how to compare a power consumption of your devices

So, for a long time reading the forum and asking a question along the way, why I have so quickly battery discharging on my phone, I came across an interesting thought: "and from what I actually compare?. someone wrote about 5% per night, someone love to confess on the tab "Journal of the battery and it shows that he is the difference between" running "and"phone on "0.5%. but what is a night (for me it's 8 hours for someone 5). which network who have (GSM or 3G)? Also, we are constantly being developed and modified ROMs and kernels, which also constantly featured the words "lowered energy consumption."
And how do you actually compared the energy consumption of the old firmware to new. usually it sounds like "on the old firmware, I charge the phone every day, and now I charge every 2 days." but we don’t know details of how actively you used options of your phone on the old version, and how use now "(for me, For example the first 3 weeks after buying the phone had lived only one days, but now 2-3 days. but not because the new firmware, but because I'm tired of constantly digging through the phone settings and install the different soft, thus discharging it).
So, our challenge is to develop an algorithm (and in the future opportunities programs), as can be correctly and objectively compare the power consumption of our devices. That at least from the transition to the firmware to the firmware, from one kernels to another to be sure that the phone will not live less than before. Search for programs of this kind I have not been successful, can someone tell me if he knows?
actually look to you for ideas, how best to develop an algorithm testing the phone, and simultaneously bring your own.
then everything will be set out with respect to the software part, because hardware is not subject to us
1. So, first of all we need to start with any initial data. Having read all the threads about power consumption, I have come to the conclusion that the original data should include the following:
- Do wipe battery stat. We fully discharge the phone till shutdown and charge it in off state. after the device is fully charged, unplug it from the charging device and do wipe batter stat from the recovery menu
- To make the calibration of the battery you need to discharge and completely charge in turned off state the device at least 3 times
Here is one of the toughest parts, considering the long battery charging our phones. charging off-state means 4 hours of losing connection. and we need to do it 4 times. One discharge-charge cycle for a complete calibration system, as I understood , is not enough.
all the widgets and programs that can perform any action to in background must be disabled.
well, and then discharges our apparatus up to 95% in quiet mode, to give the battery a little bit cool, and eliminate trouble with 99-98-97% and you can begin testing.
2. Measurement tool. I would have chosen for this purpose, program or Battery Monitor Widget (she effects on discharging battery, but it writes logs, which can be tracked over time the battery status in percentage and millivolts) or JuicePlotter (don’t have logs. We have to extract data from the graphs that it constructs). JuicePlotter showed the best result in power consumption while the CPU time drain more than BatteryMonitorWidget - here's the first interesting fact. Now I’m testing these programs repeatedly to confirm this effect
3. In order to reduce measurement error the device must be discharged at least 20% of one test. or better at 30%. then + / -1% in the testing will not be particularly significant. That why testing process will be long and tedious.
4. In order to understand the power consumption of device in general, you should at least try to understand and share the power consumption of its individual components:
5. power consumption of the screen. For this purpose you can use the widget to extend controls, where you can turn the screen on constantly. And choose any standard wallpaper with middle brightness. we need to measure how much battery discharging for 3 hours the screen on. for small, medium and very high brightness, respectively. you can check consumption on the automatic brightness too. is believed that the turning on an automatic brightness strongly discharge the device..
6. power consumption of the file system. In the good we ought to write a program that creates a file in a loop on the internal flash drive, and anything he writes and deletes the file. Repeat the loop few thousand times to the total time was about 2-3 hours. but until there is no such a program, you can simply copy the file size of 2-3 gigabytes of internal memory with a program such as ES Explorer. In this case, the screen must be enabled to minimum brightness (since we already know how much the phone is discharged from simply turn on the screen) to control the copy process and accordingly the percentage of discharge.
7. Estimation of consumption of the processor. To do this, too, we can write a program that would do any arithmetic operations within an hour of time. But here we get the maximum load, therefore the maximum power of the processor. and it is unlikely it will be different from the firmware to the firmware . But our processor is also able to reduce the frequency and consequently reduce power consumption. And here I think there is much to improve the software. Therefore, must be differences from firmware to firmware. And the best test for this, I think, show any video on device, it loads processor to 30% on average (better view a videoconcert, so there isn’t quite boring) for one hour and thus measure how much discharge our batteries from this view .
8. Estimation of Wi-fi. Then the test can serve up any file copy from PC (connected through wires to an access point, so this segment was not the brakes) to our unit. Since the maximum speed that I managed to squeeze out of the standard N on my Captivate is 0,8 MB / sec I think copying the file size of 2GB will be enough to discharge our device is not less than 20% battery. copy can be perform using the same ES Explorer
9. Rated power consumption in standby mode. here it must enable the network only GSM. turn off the wi-fi and bluetooth. the screen went off and did not touch the machine for 8 hours. Better course would be 24 hours, but I think hardly anyone will be able to perform such a test
Actually look to you for your suggestions and additions, as can be realized by comparing energy consumption of our devices.
from the general collective thoughts we can open thread with algorithm, where you can write your test results according to the algorithm ... and make any conclusions.

[HOW-TO] Battery saving tips

As some of you have been complaining about your Infinity's poor battery life, I thought we should start a thread on getting more out of its battery. I invite you all to share your experiences, hopefully we could come to sth helpful together.
Perhaps when the development's carried on further by more XDA developers, we can split this to stock ROM and custom ROMs, as probably the latter will have more of these already included.
1. Arguably full charge and discharge does nothing good on modern Li-Ion batteries and it's rather advisable to keep it balanced - discharge a little, don't push it with charging all the time (however in case of the Infinity, as with many other devices, the charger will just stop consuming energy after [almost] fully charging your device). There is one reason for doing a few full discharges and charges however - so that the battery monitoring apps/widgets can learn more about your battery's life and power consumption.
2. Monitor your battery life and monitor it wisely (don't use power-consuming apps and widgets). I personally like Battery Monitor Widget, as it gives you mA and % / hour (either drain or charge), which is pretty cool, as you can see how much your usage exhausts your battery in real time. This way I've found out that switching the WiFi off while reading books actually gives me battery drain closer to 10%/h than 15%/h etc. You can see some other in this apps thread. Try different apps and see what fits you best. Don't rely on system battery usage stats, see what other apps show us and what apps and processes drain the most of your battery, show most wakelocks, etc.
3. Use as low power mode as you need (administered most easily through ASUS/Android notification bar on the bottom of your screen). There are three power modes:
power-saving (keeps your CPU at 1 GHz according to some apps, 500 MHz according to others) <- can give you up to 2 additional hours
balanced (keeps your CPU at 1,5 GHz)
normal / performance (keeps your CPU at the highest speed - in stock kernel 1,7 GHz for the 1st core and 1,6 for the others)
You have to try these for yourself. Most games run well on balanced, but may sometimes need the performance mode (keep in mind that overheating your CPU and GPU may cause the clocks to actually slow down). You may also find yourself happy with the power-saving mode, which really helps your battery to last longer, but I've noticed issues with some apps while running it (problems with pdf rendering, for example), as it probably changes more than just the CPU clock speed, but also the system behaviour. I hardly ever leave the balanced mode, mostly when curious about benchmark results
There are also different CPU governors in Android/Linux kernel, which you can change if you are rooted, but perhaps leaving the default "interactive" one on should serve you well (you can also try "conservative", but it has been argued it doesn't save your battery so well in the long run).
(if rooted) You can also use CPU management apps like SetCPU, create your custom profiles or use the default ones according to your needs (for example ).
4. In ASUS setttings switch on both power-saving options at the very bottom of the list (WiFi and dock deep sleep [the former is the same as choosing "never" in WiFi advanced settings]).
5. Keep the screen brightness as low, as you can. It's better to adjust it manually through the notifications bar or a widget than to switch auto-brightness on (some recommend LUX app, personally I had problems with it trying to outsmart me when I was doing some manual changes). I like to keep it around 30-40% indoors during the day and 0-10% at night.
6. Switch WiFi off when you don't need it, unless you need it on constantly.
For me, it sometimes also helps organise my work too, when I don't get constant notifications or when I'm not eager to browse the web all the time, when just reading something and taking notes.
7a) (if rooted) Make your device fall into really deep sleep...
Add these to your build.prop file (see the thread on tweaking):
ro.ril.disable.power.collapse=0
pm.sleep_mode=1
7b) ...and make it scan for available WiFi networks less often, for example every 180 seconds (same as above):
wifi.supplicant_scan_interval=180
8. (if rooted) Switch off all the apps you don't need that auto-start on boot with a program like System Tuner.
(f not rooted) Use auto-killer for the apps you don't need (if rooted you can do the above two together as well).
You can also deactivate unused apps (settings -> apps -> [select app] -> deactivate). Remove bloatware, too (see the first few posts).
9. Adjust your minfree values, so the low level system task killer will take care of the apps running in the background for you (see the thread on tweaking). You can try with different settings and see what's better for you. Some apps drain your battery life even when you don't use them, while others don't and it's better to leave them in the memory than run them all over again every time. Do some tests and see what's best for you, if you have time for it.
10. Switch auto-syncing apps to lower values when possible (sometimes PUSH is better, sometimes worse for your battery life).
11. Keep it simple. Too many funky animations, floating wallpapers, lots of nice widgets will make your battery drain really fast.
12. Try different custom launchers, you can set more UI behaviour rules in these (see this apps thread).
13. Use a dark wallpaper and dark themes / night reading modes (see why).
​
PS JuiceDefender reported to having disabled deep sleep, so stay away if possible.
Hotmail app has been said to trigger wakelocks, while overriding system wifi sleep when screen is off, so keep that in mind if you want better battery life over constant e-mail syncing.
Hit [THANKS] if it helps.

First of all, thanks to d14b0ll0s for yet another great write up. I am one of those concerned with the battery life of the Infinity. Though some review says it got up to 9-9.5 hours with BALANCED mode I believe is the mistake. By using Power save mode, I think we can potentially get to that level but still hard.
My system is NOT rooted, but I have noticed significant change in my battery life so far with following:
1. Balanced Mode to Power Save mode.
This gets me like extra 2 hours or so. WIthout this change, 5-6 hours for my usage and with this it goes up to 7-8 hours screen time.
2. Under Wi-Fi Setting change Use wifi during sleep mode (mine is in Japanese so exact wording may be different) to never. Default setting was always. Prior to this change, I lost quite bit overnight unplugged; however, after the change it loses negligible amount.
Now rather than these, I am trying to play around with Juice Defender, which was recommended by d14b0ll0s in best application list he created. I have initially downloaded Juice Defender Free edition, and noticed may be minimal gain over #1&#2 already instituted. But concept was great. So I ended up purchasing Ultimate edition, which allows us to control when to turn of WIFI per individual application based without Root i.e. while reading PDF I don't think I need WIFI connection.
https://play.google.com/store/search?q=juice+defender&c=apps.
I am still tweaking and playing with Juice Defender, but I am certain without change in #1,#2 (which are actually taken care by Juice Defender in its own way), I can gain same battery life and my hope/guess is I can get even more battery life.
So in conclusion, for those not rooted try Juice Defender (at least free version). I will let you all know how the ultimate version does in next couple days.

Thanks for this! ^^ Post 1 updated.
Have you noticed what power-saving mode changes apart from CPU (& GPU?) clock speed? Does it change auto-sync settings or unload some modules? I'm not using it, as it is too slow for me to render big pdfs consisting of scanned jpgs. But when I'm reading them with WiFi off on balanced, I normally get 9.9% drain per hour according to Battery Monitor Widget, which even with some other things that I do from time to time and some additional rendering when opening new files should give me about 9 hours on a single charge. Browsing over WiFi gives me about 7.
The Wi-Fi settings you mentioned are the same as WiFi power-saving settings on the bottom of ASUS setting list, but I've clarified that in post 1 now.
I'm happy JuiceDefender helped you, it's good to advertise it here. I'm adding the info about your post apart from the link to the list of apps.

Thanks
I would also add that it's good the deactivate unused apps/widgets (settings -> apps -> "select app" -> deactivate)
it's only possible for apps which cannot be uninstalled

Good point! ^ Added (-> p. 8).

Mine will be here this weekend.
Thanks d14b0ll0s

Look very useful! I'm about to try.

I think the standby time is awesome. Wifi off, power save mode enabled and left the tablet over night right after full charged battery w/o dock. After 10h still 100%.

#nice

The system measuring system isn't exact, and early on so are all the indicators, so don't rely on it too heavily. There may be a variance of 1-3% and a lot more in the usage indicators. Try different battery / apps widgets and compare the results.
Anyway, deep sleep is nice indeed. It normally drains about 0.2% (-0,5%) per hour, mine is now 98% after the night off the charger and responding to a few e-mails in bed

Thanks for the info, it's appreciated.

Antutu's Battery Saver worked great on my 101, I'm observing how it will regulate the power drain on my 700. Hopefully it will keep the back of the tab cool as well.

i think the problem is when you have wifi on!

this is good when you have wifi off. however, when you have the wifi on, it shows 80% wifi and 20% screen consumed by battery. you can stop network access by disabling wifi from Asus customized settings and also in wifi setting, you can keep wifi on during sleep to NEVER. this helps a lot..

Stock battery (usage) stats are not relevant, use other battery apps or widgets for that.
I've heard good things about AnTuTu's bat.sav., but also that it doesn't let you have more insight into what it's actually doing, so JuiceDefender seems a better option in that matter.

d14b0ll0s:
Do you know the specific voltage setting / configurations coming out of the usb line?
Is it 16V and how does it distinguish between 16V and 5V on the single USB cable.
For example does the voltage cable go on different lines for 16V and 5V for the TF700?
Or is it 16/5V dual switchable on the same power cable?
I'm asking this is because there's interest to charge the tablet by using alternative methods such as mobile battery with 16V setting.
If so, then does a DC to USB cable be suffice for the job? Or is the cable wired differently as proprietary ASUS?
Thanks!

Sorry, I wouldn't know that. There some ppl here that are doing some testing with the batteries and hardware, perhaps the_kreature or MartyHulskemper could know something. You should post it as a thread in Q&A too.

First of all, the charger gives 15V, not 16V. Avoid giving your tablet too much voltage as that can kill it...
Secondly, the included cable is a USB 3.0 cable and therefore has 5 extra pins (you can see them if you look straight into the USB plug). These extra pins are used to get 15V from the charger. I don't know exactly how that works, but I guess the tablet tells the charger it wants 15V over the power lines (same power lines as 5V) rather than the charger giving 15V over these extra pins (because that could be devastating to other USB 3.0 gadgets). This is why the tablet won't charge if you insert an old (USB 1.0 or 2.0) extension cable between the charger and the tablet.

Hey I'm running with wifi on during sleep and I seem to get great battery performance (2% loss over 11 hr standby). No build.pro tweaks so no deep asleep our anything like that. I'm wondering if anyone else has gotten similar performance?
I thought it was interesting because the results were the opposite on my tf300t, and my usage pattern hasn't changed much between the two devices.

Same here. Battery life on deep sleep with WLAN is great!
But I think the Infinity needs a lot of power while reading news, tapatalk, Reader HD..
Not more than 4 hours Screen On Time!
And that with balanced mode and 50% brightness.
Any problems with the fifth companion core?
PS: Is there an app which shows the activity of the different cores?

Getting a full day out of your battery isn't something that should be fantasized over, but rather is absolutely attainable with most phone configurations. With following this [GUIDE] you should have no trouble getting more from your Atrix 2's battery life. I will outline several "usual suspects" and "battery butchering bandits" that some may already know of, and some that you might not have ever considered. However, if you try all of these it, may ruin your Android experience because you’ll be constantly fussing with your battery; that's not what this is for. These are ALL the tips/tricks I know. Even I don’t use all of them. Using just a few of these (possibly even one or two) should be enough that you notice an increase in your battery life. So, n00bs and more knowledgeable users can both benefit from this, and for the more resident members here, we've all seen the threads like, “Please help with my battery issue”, “Does undervolting save you battery life” or “Getting horrible battery life”, so this should help give everyone some great ways to improve upon your battery's performance and lifespan between charges.
First off, let me start by telling you all to be realistic. What I mean by that is this: You Atrix 2 is meant to be used! Your Atrix 2 is more than just a phone, it is a pocket-sized computer, an arcade full of your most favorite games, it is meant to be talked on, played with, downloaded to, uploaded from, tweaked/modded/themed/rom'd and everything else that you may desire! So, again, after reading and implementing some of (or all, if you're neurotic) the things I'll outline, hopefully this will alleviate some of the questions you may have as to why your battery performance isn't everything you anticipated it to be. Though, if you think you will get days out of your battery's life by following these suggestions, you're either not using your phone for anything other than holding down a stack of papers, or you're just not being realistic. Will these suggestions help give you more from your battery? Absolutely. I know this is all (well, mostly) very elementary in effort, but overall this WILL HELP you.​
*"There are many things to consider when thinking of your battery's performance, such as: Animation Speed. Polling For Notifications. GPS, WiFi scans, Overclocking. CPU/Ram Usage, Proper Sleep, Widgets, Brightness, 2G/3G/4G Data Usage, Call Time, Text Volume, just to name a few ~THESE are the things that really affect your battery life. The bottom line is, if you truly want to save battery you are going to have to get your hands dirty... there simply isn't a "one-click" (or one-flash) solution."​
*STANDARD DISCLAIMER: I cannot be held responsible for any and all damage related to Hardware loss or Data or Software, which the user might cause while attempting these procedures. Additionally, I am taking the liberty to assume that anyone who attempts these procedures understands the potential risks involved. Though, there should be no such issues to arise from following this guide, I am still exempting myself from any liability.
---For All Users (Rooting Not Required)---
​
1) Turn Off Your Radio(s) When Not Using Them:
Radios are what connect your phone to the rest of the world. You have your general mobile connection, WiFi, data/internet connection (3G), GPS, and/or 4G. Those are listed in order from least to greatest in battery consumption. If you’re not using the radio turn it off. If you know you won’t be online for a long time, why turn 3G data on? If you’re at home, use WiFi instead of 3G. If you’re not using Google Maps why is your GPS on? You’d be amazed at how much battery life you can save just by turning off the radios that you aren’t using.
2) Vibrate Uses More Battery:
Anytime your phone vibrates a lot of battery is used. This include haptic feedback. A lot of keyboards have the option to turn off haptic feedback and I would recommend it. If you’re a heavy texter you’ll notice very quickly how much longer your phone will last. Also, if you’re in a place where you can easily hear your phone why do you need to have vibrate enabled? If you know you’ll be able to hear your phone there’s no reason for it to be buzzing too.
3) Don’t Use Task Killers:
Crazy, right? Android has it’s own task killer that’s actually very good. If programs are using too much memory your Android OS will kill it. A common misconception is that apps run in the background forever; this is not true. If an app is using too much memory (which links to battery life) it’ll be killed by your phone. That’s why if you play a game, check a message, and come back the game is still running. It’s memory usage isn’t that high. However if you put your phone down, walk away for an hour, and the game is still trying to run in the background, there’s a good chance it will be closed before you come back. Separate task managers have to constantly be running in the background which can actually use more battery than it saves. Yes, task managers can use more battery than claim to save.
4. Power Cycling:
Not sure about the real effectiveness of this charging policy, but some users have tried it and have claimed to have had good results from it. So, to begin with the phone in the on position, fully charge the battery with the phone on. Once your Atrix 2 is fully charged, unplug the charger until the led goes off. After the led goes off, plug the charger back in. When the led turns green , power off the phone. Now, with the phone fully powered off, 1) Unplug the charger. 2) Wait until led goes off. 3) Plug charger back in until the led turns green. When it turns green, unplug the charger again and go to step 1). Repeat steps 1) and 3), 10 times. This may take anywhere from 30 seconds to 30 minutes per cycle. Typically only about 1 minute though. It takes too much work for me, but I’ve done it once just to test it.
5) Don’t Use Live Wallpapers:
They look awesome, right? They also use a lot of battery (especially the more complex ones). We’ve all used live wallpapers to show off how cool our phones can be, but for daily use they can KILL your battery. Also, your animations will be a factor in diminished battery life expectancy. To adjust this, simply navigate to: Settings>Display>Animations>set to "Off or Medium". #1 when it comes to what is eating your battery, is your display. It always has been and always will be, so accept it and try to do something about it. If you don't believe me, go to your Settings>Battery> and see just how much percentages the screen takes up. But, you want to do something about this, right? This part is easy. Just lower the brightness. You can set it to a brightness that is low but you are still able to see well enough to function. Live Wallpapers fall into this category. They are cool to look at but static ones take up less RAM and also less display because they are not running all the time in the background. These screens are very bright at 100%, so tone it down.
6) Watch Your Applications:
You have to pay attention to your applications. I repeat. You have to pay attention to your apps! Especially if they run in the background. This can be anything from a harmless .99¢ game to a monster like a Live Wallpaper. The battery drain threat is twofold here because the application is running in the background but it could also be using its anonymous data collection abilities and sending that back to the Mother ship. Ever wonder why your signal bars in the status bar have arrows or other animations going back and forth when your phone is just sitting there? This is because some application is transmitting data, whether you are using it or not. There are apps in the market that monitor these situations like Watchdog Task Manager Lite or you can adjust app permissions like LBE Privacy Guard. Data transfer is #2 on the "What Kills My Battery" list.
7) Worthless Widgets:
They look cool. But widgets are nothing more than RAM and battery hungry monsters that you purposely put in your home screen. Think about it. What does a widget really do? All it really does is monitor an app that you have running. So not only is it running and taking up battery and RAM but the app that it is linked to is running in the background a la Facebook, Twitter, Google+, CNBC, MSNBC, BBC, …the list goes on and on because they want us to put THEM on our home page. What a great marketing campaign the widget is: "Hey, look at me new home screen!" "Cool. Hey what widget is that?" "Oh, it is (whatever widget)." "Nice, I’ll have to download that tonight when I get home." Right then and there, they have you and your battery. If you're serious about getting the very most out of your battery, get rid of the widgets. I know, they're hard to resist, but trust me, your Atrix 2 will be a better place if you want the most out of your battery.
8) Set Your Screen Timeout:
Some phones start with their screen timeout at 3 minutes or more. That’s completely unnecessary. While you don’t want it to be instant, you know your preferences. Set it to as low as you see fit. The sooner your screen goes off, the longer your battery life will last. I set my screen timeout to the lowest "never" -but, in doing so, every time I am done checking emails or sending a text, I kill the display with the power button to turn off the display. This takes some habitual conditioning, and if you're used to allowing your phone the responsibility of turning off the display for you, it might bode well for your battery capacity crusade to simply adjust this to the minimum. But, if if you're like me and like 'control' over your display, I recommend you still set the timeout to the lowest possible setting, in the event that you forget to manually shut the display off yourself. It's just good practice when going for battery life longevity.
9) The Charger, and What You Can Do Regarding it:
Using certain chargers causes a wakelock on your phone that prevents it from going into deep sleep. This can result in roughly 10% battery attrition, regardless of activity or screen on time. Before you try anything else, you should test each of your chargers and make sure they aren’t causing a wakelock. Though this shouldn't be of concern if you are using the stock wall charger that came when you purchased your Atrix 2, there are other aftermarket ones that you may not suspect as reasons to worry about charging your phone with. If you are not using the stock charger, and you suspect you may have a problem, or may be curious to find out: Install CPU Spy from the Play Store. Open the app to see how much time your phone spends in each CPU state. If Deep Sleep is a very small percentage, or Deep Sleep doesn’t even appear, you have a problem with your charger. Or, follow the method below to test each of your chargers:
Testing CPU Spy:
1) Plug your phone into the charger and turn the screen off. Leave it charging for about 30 seconds. (Don't do this with a fully charged phone, as I don't know how that affects the testing)
2) With the screen still off, unplug the phone from the charger.
3) Open CPU Spy, hit the menu button, and "Reset Timers". Turn the screen off.
4) Let the phone sit idle for a few minutes with the screen off.
5) Turn the phone back on and refresh the timers in CPU Spy (menu button again).
If Deep Sleep doesn’t appear in the list of CPU states, your phone is experiencing a wakelock brought on by the charger. It’s probably spent the majority of time at 192mhz or 384mhz. To further confirm this, leave your phone unplugged, restart it, leave the screen off for a few minutes, and then check CPU spy again. You should now see it going into Deep Sleep.​​
10) Your Camera Flash and Battery Don’t Get Along:
If you like using your camera LED for a flashlight realize that will absolutely MURDER your battery. In all seriousness, your flash uses battery more than any other process on your phone. Turn off the flash. Don't set it to "automatic", you should know when you will need it and when you will not. By setting it to "automatic" you're relying on the phone's light meter to determine if the flash is needed. Sometimes it is, and other times it isn't.
11) Low Cell Signal Hurts Battery
Your phone is always searching for a stronger signal…This process gets more hectic as the cell signal goes down. So if you’re at one bar your phone’s battery life will drop faster than if you’ve got full coverage. There’s not much you can do here, but if you’re in a place where your phone has little to no signal anyway, you probably won’t be making calls so you might want to just turn on airplane mode or your phone off. And with Airplane Mode, you can toggle the airplane mode on/off 3 times in a row, that will reduce your Cell Standby battery usage. It should only be necessary to do it once after flashing but if you think Cell Standby uses too much power at some stage, you could toggle again the airplane mode 3 times. This is a handy little trick, not well known, but should give you some relief with Cell Standby usage. I travel for my job, which means that at times, I do not get good reception, or bounce around between Edge/3G/4G, and each time that happens, your Atrix 2 is sucking more juice by trying to find a good signal. If you are not in a static network, meaning one that is either 3G/4G at any given time, without locating off-network tower connections, turn your radio off or switch to Airplane Mode.
12) Speaking Of Syncing…:
Check your settings to see what is syncing and when. You probably have things syncing you don’t even use (stocks, news, contacts, etc). You can turn those off and edit the other ones. I don’t need my contacts’ statuses every hour, so my facebook sync is scheduled for once a day rather than the old once an hour. Find out what you need and how often you want it, and turn the rest off. I know you are very important and you need to know what LeBron James is doing right now, or that you need to upload a picture of you and your girlfriend every time you two are at a party, drinking beer. That is fine and I applaud you for it, and will probably download the picture and Photoshop myself in your place. This is not the problem. Syncing your accounts is. That is what is causing battery drain. Do you really need to have your FB widget (see widgets section) streaming all day long? I doubt it. Kill it (not LeBron, but rather the auto-syncing). Every time you “friend” someone their numbers, contact info gets sync’d to your phone. Also, there are settings in Facebook, Twitter and Google+ that you can upload pictures instantly. Don’t do that. Once you do, it is out in the Ether-World and just swallowed a bunch of battery doing it too. Settings>Accounts and Sync>Auto-sync>uncheck it
13) Don’t Use GPS Unless You Have To:
Some apps give you the option to precisely determine your position using GPS, or make a general estimate (usually within 100 meters) based on WiFi or 3G data. While this isn’t always the best (like if you’re driving or getting navigated), try to use the 3G connection when it doesn’t really matter. The data radio uses far less battery than GPS.
14) We're Gonna Need A Bigger Boat, erm... I Mean Battery:
If still not completely convinced that you have have stellar performance from your stock Atrix 2 battery, you can always check out the Atrix 2 Accessories threads for suggestions and/or discussions on extended capacity batteries. I've never used one myself, but don't see as to why this wouldn't certainly add to your life expectancy of your battery -assuming you're choosing foregoing the suggestions above, and simply insist on having your widgets and eating them to -or your battery, for that matter. Nonetheless, there are several manufacturers that supply an aftermarket extended capacity battery for the Atrix 2, just use your pal Google to help you find one.

---For All Users (*Rooting Required)---
​
*FOR ROOT USERS: If you’ve rooted your phone you have a few more options. You don’t gain too many more options, but they are even more effective than the ones listed above.
Underclock Your Phone:
Just like SetCPU can overclock your phone, it can underclock it as well. Set it to underclock when the phone is sleeping or even lower the max clocking speed. This will give your CPU's scaling frequencies a lower "resting" point, and will not allow the load of the CPU to be any higher than the maximum setting you permit. I know everyone who likes to get their hands into the belly of their Atrix 2 and start tweaking it loves the idea of overclocking, but c'mon, you don't have to run your CPU at 1.3GHz all day, everyday. Scale that baby down when you don't require such a high CPU load, and trust me, your CPU and your battery will thank you. Also, along with underclocking your CPU, you can undervolt as well. This will allow (after some testing you'll need to do first to make sure you're not undervolted too low for stable CPU loads) for your Atrix 2 to run at a lower voltage consumption, and with these types of settings, you can allow your Atrix 2 to run at your desired CPU frequency scaling, but a slightly lower voltage rate. *Note: As aforementioned, some testing is required for this to be effective with both your CPU's table values, as well as how it may improve your battery's life. Also, please reference This Thread for the latest kernel/module overclocking and undervolting methods.
Wakelocks That Destroy Your Battery Life:
If you're not familiar with wakelocks, they're basically processes that run on your phone that prevent it from going into deep sleep. Deep sleep is the mode your phone should go into when you're not using it so that it can conserve battery. Some wakelocks are intentional, while others can be the result of rogue apps or system processes. If you're trying to maximize your battery life, you know this already. Some wakelocks are happy, friendly things, but many are silent leeches, sucking away your battery life while you remain blissfully unaware of what's happening. First off, you have to understand the difference between kernel wakelocks (KWL) and partial wakelocks (PWL). KWLs are wakelocks caused at the kernel or hardware level. Some of these are benign, and some of them are vampires. The only way to solve them is to change how your phone behaves. To effectively find your wakelocks, you'll need Better battery Stats It's free to us XDA users. You can get it IN THIS THREAD. More on wakelocks can be found in the post below.
Use SetCPU:
Create a special profile that forces the device to run at low clock speeds when the display is off.
Go to profiles
Check Enable
Press Add Profile
Set the following:
Condition: Screen Off
Max: 600MHz Max
Min: 300MHz Min
Governor: ondemand
Priority: 50
Press Save
On the Main tab make sure you have
Max: 1000MHz
Min: 300MHz
Governor: ondemand
Scheduler: deadline
Clean Out the Bloat:
Some of the bloatware and unnecessary applications on our Atrix 2's can drain battery. I really recommend you freeze the applications by using Root Freezer and run your Atrix 2 for a few days after you have frozen an unwanted application, and certainly before you decide to uninstall. This way you won’t accidentally uninstall something your phone needs to remain stable. Albeit, most of the custom roms that you will see here are already "de-bloated", if you're new to rooting and Android, and haven't quite decided that taking the next jump to flashing roms is for you, use Root Freezer to "freeze" applications that you suspect are bloat, until you decide to run a de-bloated ROM -and you will, eventually...
The Stock ROM Sucks:
If you’re still unrooted and on stock Gingerbread, I feel sorry for you. What the heck are you doing on this forum if you’re scared to flash a new ROM? This guide would be way too long if I tried to explain the battery improvements you might see by stepping up to the Stock ICS leak. You’ll probably see even more improvement if you flash one of the many custom ROMs in the Development section. If you’re dedicated to getting the most out of your phone, spend a weekend reading the ever-loving crap out of the stickies in the Development forum, and the [ROM] threads. Only after you have read those threads and feel like you have a good understanding, backup your phone and flash a new ROM on it. As long as you’ve backed up properly, you can flash between several ROMs and choose the one that works best for you. If you have any questions about the ROM you’re trying to flash, ask in that ROM's specific thread, don’t start out by creating a new thread in the General Section. You did do a search first, right?
Lost DIR Liability:
Let's say that you have your phone plugged into your PC and for some reason you, in a fit of rage, jerk the plug out without unmounting it first. This creates a file that is put into your LOST DIR folder on your SD card. Anytime you don't safely unmount the SD card, it will create a file in that folder. In the scheme of the SD card, it isn't too much, but I don't like having useless items free floating about. Clear them out using Root Explorer or a like Root File Explorer, and this will free up some (depending on how many times this has been done) valuable memory real estate.
Tombstones:
So you are downloading an update from the market and for some reason your phone freezes and the Force Close-Retry-Wait doesn't work out for you. You have to do a battery pull. Frustrating I know and the memory takes a hit too. Every time you have to do a battery pull because of a freeze up or something of the like, it creates a TOMBSTONE file in /data. These are useless and can be deleted. If you are flashing ROMs and are constantly having to do battery pulls b/c market crashes or an app freezes, then you are creating a Tombstone file. Here is where your file manager (with root) will help. Go into /data and scroll all the way to the bottom and open /tombstone. There should be some files in there and depending on how many there are, I could be a nice chunk of wasted memory. Just select all and delete. They are not needed. Your internal memory should go up by doing this.
Lost & Found:
Same scenario, but now go into /data/ cache or /cache and you'll see Dalvik Cache (don’t mess with this), Lost & Found and Recovery. If you tried to download an app and it got frozen for some reason and had to do a battery pull, the apk will be free floating in there, uninstalled (free floating radical). You can delete this. While it isn't in the Dalvik Cache folder, it is taking up space. Once you are able to download something completely and correctly from the market, it will populate into Dalvik Cache correctly and won't be a free radical, as I like to say.​
---For All Users (Miscellaneous)---​​​​​​
Some More Memory Clearing Tips:
Home Launcher:
If you have a 3rd party home launcher, see if it has the ability to long-press an icon to take you to its screen in the Manage Apps section. I use ADWex and if you long-press on say Market, it takes me to the same place as is I were to go to Settings>Applications>Manage Apps>Market. Instead of all that, just long-press on the icon and BAM! it takes you there. Here you can clear out your cache for the market or delete the data (if you need to do that). Or clear the cache of the XDA app because you looked at too many posts with pictures, etc.
Browsers:
These develop cache that takes up memory and space, especially the stock browser. If you use a 3rd party, you can get the settings to clear cache, cookies, passwords,…on exit. I use Dolphin, but I am pretty sure that most have something like this on them. (side note: most 3rd party browsers once exited will not run in the background unlike the stock one)
Media:
So you download a bunch of mp3's from the internet or you've clicked on some pix and saved them to your SD card. Or maybe you just felt like wiping your card and having a fresh start. Every time you reboot, you phone will scan media. No big deal, but the more you criss-cross things from PC to phone and back again, it can create a bunch of double files in your media cache on the phone. With the proper placement of .nomedia files (this prevents your media scanner from doing just that, scanning media- i.e. pix, jpegs,…Don’t place a .nomedia in your music, album art or DCIM files**bad). Every once in a while, I'll hit the Diskusage or go to Manage apps and clear the media cache. Then I got to my file manager and the DCIM->Thumbs and delete the thumbnails files (should be 2). Unmount the SD card and remount to start the media scan, pull up the Gallery and wait for the thumbs to come back (depending on how many you have, this could take awhile). By doing this you can get almost 5 mb back if you have a bunch of double scans in your media folder.​
Applications That Use Advertisements:
Try to avoid ad-supported applications, if you can. A research showed that in apps where there is adds, 70% of the power use comes from downloading and managing those adds to your screen. With just a 30 second use of an application that uses ads, it might drain your fully charged battery anywhere from 0.35% to 0.70%, which is enough to completely discharge the battery within a couple of hours if the process is repeated. This, according to a team of researchers, show that applications using advertisement support can take a high toll on your Android smartphone’s battery. The researchers analyzed how Android apps use the battery and concluded that the ad-serving processes that run in the background are responsible for heavy battery drainage. This may not seem like much, but so many applications that are free utilize advertisements and are blasted about the bottom or top of your application. I know I'll likely get ostracized for mentioning this, at least by some of the developers who rely on ad-support within their applications, but there is a way to eliminate these ads from showing themselves in your application(s). This is for BOTH rooted and un-rooted devices, as there are applications available from Google Play Store, such as AdFree Android (for ROOTED users only) or you can find one that will work on a non-rooted device. Or better yet, you could pony up the nominal dollar or two and show your own support for your favorite applications by buying the paid version, and thus eliminating the ads in that manner.​
*I will be updating this OP as I see necessary, and if anyone has useful tips that I may have missed or overlooked, please let me know. I'm aware that there are threads of this capacity floating about through XDA, but I have taken the liberty to create on specifically for our community.

Wakelocks Explained
Two final notes before I get started with the Wakelock Portion of this guide: Do not go wakelock hunting right after installing a new ROM or clean-wipe reinstalling your current one. New ROMs cause the phone to go nuts for a little while, as things decache and little behind-the-scenes tweaks are made. Wait one full battery cycle (100% to 0%, which you're probably doing to calibrate after a clean ROM install anyway) before trying this, or you'll drive yourself nuts. Also, remember that solving one wakelock will often create another, especially early in this process. That's normal and to be expected. God does not hate you, your ROM of choice is not crap, your phone is not glitched, and a clean install while your current ROM is still settling in will only make things worse.
So, how do you track these wakelocks down with BBS? This is a really complicated procedure, so make sure you're with me. First, open BBS. Then, see the drop down menu at the top that probably says "Other" right now? Tap it, and then you'll see "Kernel Wakelocks" and "Partial Wakelocks" below. That was obscenely difficult, right?
There are a couple of other features of BBS that we'll make extensive use of later, but there's one you need to know right now. Tap your phone's menu button to get the BBS menu up. Tap on "More". See the button that says "Set Custom Ref."? You'll need it--you'll need it a lot.
Last, but certainly not least: modifying your system in any way, including altering or deleting processes needed to resolve wakelocks, can have unpredictable results. Use caution and make backups of your apps and data, as well as nandroid backups, frequently while finding and eliminating wakelocks. Any modifications you make are done at your own risk, and I assume no responsibility for any damage you may do to your phone while cleaning out wakelocks.
With that said, we'll get started with the KWLs, as they're the trickiest to get rid of. Use the guide below to identify your wakelock, what is causing it, and how to get rid of it.
KERNEL WAKELOCKS
wlan_rx, wlan_rx_wake, wlan_wake: This is a wakelock caused by network traffic. The easy solution would be to just turn off Wifi, but be careful doing so! If an app goes to sync and it sees that Wifi is off, it will search for a mobile data connection (which causes the ConnectivityService wakelock). If it can't find a mobile data connection, it will wait and search again at its next sync interval and/or automatically sync when the phone wakes up. This wakelock can also, deceptively, be caused by the Wifi network itself as it refreshes connections or refreshes IPs.
To fix: This is a tricky little sucker to fix, as there are so many possible causes for it. Airplane mode is a safe bet--syncing apps seem to "respect" airplane mode, whereas if Wifi alone is turned off, they'll just try to find a way around. But then, of course, you lose your ability to talk on the phone. If you're particularly unlucky, your Wifi network itself will be the problem.
PowerManagerService: This is probably your #1 or #2 kernel wakelock, and you'd probably love to get rid of it at all costs, right? Hate to say it, but there's not much that can be done about this one. PowerManagerService is a KWL that serves as a "catch-all" for your PWLs. It's a placeholder, nothing more, nothing less. Don't spend much time worrying about it.
To fix: Reduce PWLs. See below.
deleted_wake_locks: Remember what I said above about force-stopping an app and deleting its cache and data before uninstalling it? This wakelock is why. It's the PowerManagerService for deleted apps. Once the app is gone, the wakelocks it caused suddenly become unknown to the system, so they get lumped in here. This number can also go up as the system "looks for" deleted apps and/or finds more wakelocks associated with them, but not dramatically.
To fix: Make sure to force close apps and wipe their cache and data before deleting. A reboot should eliminate the wakelock entirely. If it's still showing up, wipe phone cache and Dalvik.
sdio_al: This is an annoying wakelock, as there are two potential causes for it. One's easy, and one sucks. The easy one is that you've fallen victim to the charger wakelock. If your charger shows up as AC Regular Charge, there's your problem. If it's AC Fast Charge or USB Normal Charge, your wakelock is caused by your SD card. That can be an irritating fix, but the SD card version of this wakelock is typically small enough that it's not worth addressing.
To fix: Check your charger and adjust if needed. If it's the SD card, it's probably not a strong enough wakelock to be worth fixing, but if you want to fix it, you'll have to format your SD card. If formatting doesn't work, format it again, then wipe cache and Dalvik.
alarm_rtc: This is your phone's internal alarm scheduler, set to wake up your phone for sync, push, etc. Closely related to the AlarmManager PWL.
To fix: Check your apps and make sure they're only set to sync when you want them to, not for constant push or stupid-short intervals.
mmc0_detect, mmc1_detect, mmc2_detect: I'll be honest, I have no idea what causes these. Fortunately, they seem to be minimal, so I've never wasted much time worrying about them.
To fix: Good question!
vbus_present: This is a weird one. I never could quite figure out what causes it, but it seems like it's there as long as the phone's plugged it. Strange...
To fix: Check your phone. Is there a cord plugged into it? If so, does that cord lead to a source of power? Like, I don't know, an adapter plugged into a wall socket? That's your root cause. vbus_present is a completely harmless wakelock, which will appear for as long as your charger is plugged into your phone. Set a custom reference point in BBS when you unplug, and you'll note that it's magically disappeared.
There are a number of other, lesser KWLs that I'm not going to worry about here because you shouldn't worry about them either. You might occasionally see a battery cycle with very low (sub-1%) KWLs, but that's the exception and not at all the rule.
PARTIAL WAKELOCKS
PWLs are a different beast. These are almost all caused by an app (with a couple of notable exceptions). For that reason, I won't go in-depth on too many of them, as the solution is usually to delete the app causing them. There are a few notable ones, and a few apps that merit mention.
AudioOut_1: This is an evil leech of a wakelock that will drain you dry if given the chance. For being such a pain in the app, it's surprisingly easy to get rid of. This wakelock is created whenever the phone's speaker plays a sound. With 99% of sounds, it goes away almost instantly. With keypad sounds, however, it doesn't go away so quickly, and it will sit there draining your battery for as long as it goes unnoticed.
To fix: Open Settings, then select sound. Turn off key tone sounds, touch sounds, screen lock sounds and vibrate on screen tap. It'll take some getting used to, but the extra battery you'll coax out just by solving this ridiculously simple problem is more than worth it. See DoctorQMM's post (#5), linked at the end of this one, for info on additional causes of this wakelock and how to fix them.
ConnectivityService: This will appear whenever your phone is trying to connect to a mobile data network. Excessive wakelocking here suggests that your phone is having a hard time finding a network, and an even harder time staying on it.
To fix: Test out different radios and see if one's better in your area. If you're able to control your radio bands and you don't live in an LTE area, setting your phone to hunt for GSM/HSPA connections only can save you a little bit of juice here. Not much, but every drop counts, and if you're not using LTE anyway.
AlarmManager: This isn't a wakelock unto itself so much as it's a compilation of app alarms and the time they held the device awake for. Seeing the wakelock alone doesn't tell you much, but here's where one of those features of BBS that I said we'd be using comes in.
To fix: Open BBS. Tap the menu button, then "More", then "Raw Alarms". That will show you which apps are waking up your phone, and how often they're doing so. Google will have a ton of wake-ups, but they're mostly innocuous. We'll discuss some of Google's problem apps later. Email clients will also have a ton of alarms. If anything else looks out of whack, though, first check the app settings to see how often it's refreshing. If the app is set to refresh every hour but it's set off 400 alarms in the last 30 minutes, get rid of that sucker and email the dev. You can't eliminate this wakelock, and it's constantly my #1 PWL at this point, but you can minimize it.
MediaScannerService: This is a wakelock created by the system as it scans your device for music, movies, pictures, etc. Once in a while, it will randomly get hung up and hold the phone at 384 MHz for...well...until you notice and do something about it. Like AudioOut_1, this is a heavy-drain wakelock. Luckily, like AudioOut_1, it's almost always easy to fix.
To fix: Reboot. Ninety-nine times or so out of a hundred, this solves the problem. If the problem persists, go to Settings>Applications>Running then tap on "Show cached processes". Find the Media process and stop it manually to kill the wakelock. That's a short-term fix, though, as a persistent wakelock from this process most likely means you have a corrupt media file somewhere on your phone- and there are a lot of sounds, movies and images on your phone. This is one of the few wakelocks that, if it's a regular problem, justifies considering a full wipe and clean reinstall. That's not because it's doing any kind of damage to your phone, but more because sifting through every single media file on your phone to find the culprit isn't really a practical solution.
SyncLoopWakeLock: This is exactly what it sounds like; your phone is being held awake while apps sync. There are two possible causes for this: apps syncing (duh) and a bad data connection.
To fix: Open BBS. Tap the menu button, then "More", then "Raw Network Stats". This will show you which apps are using the most data, and help you narrow down possible culprits. Once you've done so, check those app settings and make sure they're not set to constantly push notifications, refresh every five minutes or anything dumb like that. If they're set correctly and still holding sync open that long, try downloading the Speed Test app off of the Play Store and test your phone's connection. If your connection is on the slow side, it's possible that the apps are struggling to sync because of your bad data connection. Try flashing different radios to see if that solves it. If the troublesome apps remain so after you've found a better radio, it's best to just delete or freeze them.
GTALK_ASYNC_CONN family: Despite its name, this wakelock doesn't seem to be directly related to Google Talk. How do I know? I haven't had Google Talk on this phone in over a month, but the wakelock still pops up from time to time. These wakelocks can be absolute destroyers of your battery if given the chance, and unfortunately, there's no known root cause for them, and no reliable way of eliminating them.
To fix: These wakelocks will often disappear within a minute or so of generating. If one becomes persistent, reboot into recovery and wipe cache and Dalvik ASAFP. That solves the problem temporarily, but it will reoccur. Thanks, Google.
NetworkLocationLocator: What a lovely name for such a lovely wakelock. It's a minor annoyance usually, nothing more. If this one is persistent, it's because you're in an area with crappy cell coverage and very few Google-mapped WiFi networks.
To fix: Why, exactly, are you leaving Network Location on all the time anyway?
SCREEN_FROZEN: Uh oh.
To fix: If this is high on your list, you've got bigger problems than a wakelock.
PWL OFFENDING APPS
We're almost done, I promise!
Down here, I'm going to list off for you apps that will cause you severe PWL migraines, and what to do about them.
A note when uninstalling Google built-ins: Google built-ins are often system packages, and deleting them can have unpredictable results. I highly recommend freezing them in Titanium Backup for several days to see how the phone runs before uninstalling them through there as well. Deleting system processes is inherently risky, and I assume no responsibility for your own decisions.
Facebook: Any social networking app will want to sync as often as it can, but you can overrule that by setting notification intervals. Thing is, Facebook doesn't respect those intervals, and wakes up the device for data exchanges pretty constantly (even though your news feed may only update every hour or so when you want it to). This app is no better than bloat, and should be treated as such when you clean house.
Alternative App: Friendcaster. It's as good a third-party Facebook client as you'll find on Android, and it only wakes up when you tell it to.
Gmail: A running theme here will be that if there's a non-Google equivalent to a Google app, you should probably kill the Google and download the alternative. Gmail is an alarm fiend, and one of the main offenders if you have an excessive SyncLoopWakeLock problem.
Alternative App: How many email clients are out there? I've had the best luck with the stock Email app, but K-9, Kaiten, MailDroid, even Enhanced Email and Touchdown for the power users are all great alternatives. Speaking of which...
Whatever email client you're using: Email clients will always be high up on the list of alarms, and that's by their nature. Keep an eye with raw network stats on how long they're connected for, and don't be afraid to experiment. I tried K-9, Kaiten and MailDroid before settling back on the stock Email app as the one that gave me the best balance of battery life and necessary features.
Alternative Apps: Download and try out different clients until you find the one that works for you. Nothing ventured, nothing gained, right?
Google Latitude: Latitude is a tracking service. As such, it tracks you. Beyond the creepiness aspect of that, it holds your phone awake pretty often while doing so. Kill it. Kill it with fire.
Alternative App: Personally, I'm not into the whole stalking thing, but I've heard that Glympse works quite well.
Google Maps: Colossal waste of space and battery. You can do better. An important note on Google Maps: this app will still wake your device up even after being frozen in Titanium Backup. I don't know how it happens, but it does. To truly solve the alarms from Google Maps, you have no choice but to uninstall it. Do so at your own risk.
Alternative Apps: I'm a fan of Waze for navigation and MapQuest for a Google Maps-ish "browseable" interface. OSMAnd is also a great alternative, but it uses a ton of internal memory because of its offline nature.
Google Play Music & Movies: Updates itself constantly and wakelocks. Even if you freeze it, it still somehow manages to tell you that there's an update available. It's the Google zombie.
Alternative App: There are literally 100+ music and/or movie players out there. I'm sure you can find one that works for you. I'm a big fan of RocketPlayer for music, and I just use the stock video app more often than not.
JuiceDefender: What's that you say? JD sets off tons of alarms and holds the device awake for more time than I'd care to discuss, largely because of its data control settings. More harm than good, in my opinion.
Alternative Apps: JuiceDefender's main goal in life is to minimize the amount of time your device is held awake. Therefore, if you've just gone through all this to clear out wakelocks, do you really need another wakelock-prone app to do what you've already done?
Skype: Occasionally, after a call, Skype will wakelock. This is not designed to happen, and is more a glitch in the app than a forced sync. Force-stopping the app and clearing its cache have solved it for me on the rare occasion that I've seen the wakelock occur.
Alternative Apps: No idea. I don't personally consider this a "replace" situation.
That's the bulk of what I've learned from clearing out wakelocks. Remember how, early on, I specified that the search engine of your choice was the third tool? Simple fact is, I haven't installed every app on the planet, so I haven't seen every PWL out there. Because of the way my phone's set up, there are KWLs that I've never seen and never will. If you've got a pesky wakelock that won't go away and it's causing noticeable battery drain, Google (or Bing, or Ask.com, or whatever) is your friend. Good luck, happy hunting, and enjoy the extra battery life you'll get just by spending a few hours over the course of a few days tracking down and killing those wakelocks.

A Little Charging Trick
If, after rooting or more likely that case after flashing a new ROM, you often have battery reporting errors, and re-calibrating the battery along with some steps I will outline for you below will ensure that your battery is getting a full charge, and the battery reporting accuracy is right on. I run my device's CPU governor in performance mode all the time, and with a CPU overclock of 1.25GHz and various tweaks, I have about a day and a half - to a day and a quarter of full run time from my battery. This is with moderate usage (calls, emailing, text, gaming, web browsing, etc.) so you should have no problems getting acceptable battery performance after following these steps, coupled with the ones I've given in the OP:
1. Take the case off your Atrix 2 (one of the latter steps involves taking the battery out from the phone while it's plugged in. Make sure your case won't stand in the way.)
2. Install Battery Calibration app from the market
3. Plug in your Atrix 2 to charge while it's on, wait till it gets to a 100%
4. When the charge is 100%, open the BatteryCalibration app and lookup what the charge is in MV while at 100%. Write it down.
My Atrix 2 was showing ~3400MV while at 100%, which is definitely not the maximum capacity.
5. Discharge your Atrix 2 completely until it shuts off.
A good way of doing this quickly is by turning on wifi, and a video player.
6. Without turning on the phone plug it into a wall charger and let it get to 100%
7. When it's at 100%, without unplugging it from the wall charger, take off the battery cover, and take the battery out.
Your phone will "reboot" and show a Missing Battery icon.
8. Without unplugging the phone from the wall charger or turning it on, put the battery back in and wait until the phone recognizes the battery.
9. Your battery should now be recognized by the phone, and showing a charge % significantly lower than 100%.
Mine showed only 5%.
10. Let it sit there charging for 2-3 hours (or more).
My phone wouldn't charge past 10%, but yours might. The numbers don't matter much as the phone is definitely getting additional charge that could have been lost while flashing ROMs, etc.
11. After 2-3 hours (or more), turn the phone on while holding the volume down button and get into CWM.
Do not disconnect it from the charger still!
12. Wipe battery stats in CWM, reboot.
Do not disconnect it from the charger still!
13. When the phone turns on, go into Battery Calibration app again and look up your MV numbers -if you were like me, they should be significantly higher than before. After this whole process I had 4351MV at 100%, comparing to 3400MV before calibration.
Do not disconnect it from the charger still!
14. Before going to sleep - Install Watchdog Task Manager Lite from the market. Go into it's preferences, set CPU threshhold to 20%, check "Include phone processes", check "Monitor phone processes", check "Display all phone processes", set system CPU threshhold to 20% as well.
Do not disconnect it from the charger still!
15. Make sure your wifi and data connections are off. Now finally unplug the phone from the charger.
Go to bed, let your phone sleep too.
16. Success! Next morning check where your battery % is at and if you followed the instructions correctly / got lucky like me, your battery life should be 90% or more.
I went to bed with 98% and woke up to 94%. So, I consider this mission a success.

NICE JOB!!!!
Sticky... I will ask...

Nice Guide just fixed minor things and my battery is already better!

what causes battery temperature rising ? oc? data? games?

Battery temperature is a direct result of device usage. If you go to sleep at night, and are NOT charging your phone overnight, in the morning when you wake up and roll over to check xda or Facebook or whatever, the phone isn't warm, right? During the day, if you're running a browser or streaming music or just have a lot of screen time on, your phone will get warmer and warmer. It's hard to say without seeing any test results from your phone as to what is causing higher temperatures, but it's safe to say that any or all of the things you listed could be a cause. Obviously, overclocking WILL cause your phone to run warmer. Your permitting a higher CPU load value at the maximum frequency scaling, and subsequently your phone's CPU is working harder. Try some (or most) of the suggestions in this thread and see if you notice a lower temperature and battery drop as a result of the changes...

Great guide mister strider!
Motorola lied and I'm still locked mb865

Nice! Thanks for putting this together, Apex... Keep on striding, man!

Apex_Strider,
Can you tell us the final result when you applied these trick on your phone ?
Mine was not used any above, and gave me ~24hrs with heavy use, wifi on 24/24, screen on 5h using wifi. Phone for 15 mins/day, sometime movies for 2hrs.
I charged it at 22:30 PM every night.

Awesome guide. I made my lady read it. She was constantly complaining about her new atrix2's battery life. She learned quit a bit. It was easier to take this way than coming from a frustrated loved one.
You should use your skills to write a guide about how to use the report button and what help or response should be given and how to give it by non op's or those not involved in a given project for all the sudo (ha!) forum cops. (See I can't do it. My sentences are too long.) The constant correcting of anyone by everyone is getting annoying.

Nice guide Apex!! Keep up the excellent work!

Thanks guys, your appreciation of my time doing these is more appreciated than I can say. Writing has always been a passion of mine, and really the only thing I was good at in school/college- when I wasn't ingesting illicit substances by the truck load. I'm working another guide thread now, hopefully completing it by tonight or tomorrow sometime. Thinking, since I'm nowhere near "dev" status or knowledge, I might apply for Recognized Contributor. Not sure we have any here in this community, at least that's not as present here as I am. Not to slight anyone who might be one, just haven't seen any floating around in here...

Wait isn't "ingesting illicit substances" part of the college curriculum? If it is not officially it should be, cause it does, ur, um, it did help... LOL.

Are you asking for my "results", meaning my battery usgae stats (i.e.: maximum duration of battery from full charge to full discharge, screen time, etc.)? If so, I'll have to do this again, as it's been a couple of months since I had. Keep in mind, that everyone's results will vary, as it depends on so many different variables.
Also, being on WiFi will demand less from your battery than relying solely on the network connection. So, if you're 'always' on WiFi, you will get more from your battery than not. On my Atrix 2, I can get a full day or more from one full charge. Now, this is from my usage, and like I mentioned -everyone's will vary. Generally speaking, in practical use Wi-Fi isn’t any more or less friendly on your battery than cellular is. Sure there are differences, but the biggest one of all is distance. Since you’re probably a good-deal closer to your Wi-Fi WAP than you are to your cellular tower, it’s likely that your battery life will be better if you’re using Wi-Fi rather than cellular data.
The charging trick I outlined in this thread is very useful for battery reporting errors after flashing a new rom, or just is one feels like their battery isn't getting the kind of "full" charge it should. It helped me out, as well as others...

I have an extended battery that I've run through several full drain/charge cycles over the past two weeks (when I got it). However, it still doesn't register the charge % properly - it will say 5% for over a day. I used the BatteryCalibration app to no avail.
Ideas?

Try the battery charge trick above, without the Watchdog part -sounds like a battery reporting error. Are you using 1% battery mods?

No, I'm completely stock with root.
The Battery Calibration app DOES list the appropriate mV levels, though.
I'll give it a shot.

Increase Smart Phone Battery Life

Hi, firstly I'm sorry my english is a little bad )
Did you even harder to charge your smartphone is based on the first day? Here are tips that you fully based. Get away from the stress of the outside end charging of battery life and increase your phone.
1 - Home Screen Wallpaper and Theme you are using:
If you are using a smart phone with AMOLED screen, predominantly black wallpaper should be preferred. AMOLED technology while light colors such as white because it consume more power. LCD and SLCD screens, such a situation is not in question.
My suggestion is not to use an animated wallpaper for Android users in particular. Animated wallpaper, using the phone's hardware more. This is going to have to consume more power than the components.
Android users should note also displays add to the widgets. Widgets are always synchronized with the running and intense 3D graphics, as well as the equipment used for the data connection şarjınızı effects shot.
2 - Display Lighting:
It is best to leave the automatic setting of this area.
But I do not like to remain on automatic. If you need to talk I'm being honest, I always light at the highest level. Because all the ingredients here, and it will not have to perform the charging period will be longer.
But I do not want to go up to the maximum number of days gidebilecekse say it, my proposal is worthwhile to listen to. Big and wide screens of smartphones, especially in the light of day very well read. Do not force the phone to the light a little bit, then move to a higher level.
But it starts to get dark, shine your light, especially in the evening turn down the screen. Smart phones display lights to a minimum, even offers sufficient light in the evening. This is an effective tactic.
3 - Wireless Connections:
Smart phones are undoubtedly the most power-consuming units, wireless connections. WiFi, Bluetooth, GPS and 3G that are overviewed, 3G and GPS fully charge the enemy.
According to their attempts, with the closure of all wireless connections between all of them to be open to play at least half a day I've noticed.
For example, turn off the GPS. Only helpful both when business is active. Shortcuts available in Android and Symbian Belle. The option to turn on and off in a practical way. We also do not walk Bluetooth is on. It is also charged unnecessarily waste.
A clear grasp of 3G and WiFi when it is, let's not say conect. When connecting to open it. If you say'm going to necessarily turn off syncing on Android.
Sync / Sync, for a certain period of time it şarjınıza negative effect on the data are drawn. When you use the most sense to synchronize.
4 - Your RAM (temporary memory) Operate the program free to leave and at the bottom:
Most are at fault here. If you open up the application on the phone and waiting at the bottom. E, the processor is running at full speed all the time. The conclusion is obvious.
And then they were going at the charge of the phone as well as the complaints are coming slowly. Take a notebook and a lot of that time in the program's run, so let's wait. Let's see what is going to charge?
There are applications for the program terminates, especially Android. But most of these applications 24/7 has an adverse effect charging them for trying.
I would recommend this program to Android users. Download this app. Click on the widget closes all running applications. However, if you open the program by clicking the icon, you can see and what you want Implementations running off. I would recommend this method.
When you close all the system applications to open them again, the power turns off, and then spends the processor. Here you can download the program[/URL]
5 - Efficiently Manage Your Smart Phone Processor:
This section applies to users Root'lu. Root evaded users have this right, they do not die. Linux-based smartphones, especially those driven into exile in the market with a certain processor speed settings.
In general, the phones are set to OnDemand, the processor can adjust the speed according to the amount of use. For example, a 1 GHz processor that the phone does not work all the time at 1 GHz.
Their phone for the sake of example, a 1 GHz - 265 MHz range is running. I changed speeds. If you charge the phone and the maximum to withstand reduced from 500 to 128 can do. But later in your job will be completed on the processor to use 100% of himself. This will mean that the screen backlight to stay on and wait for you. I mean, at least let it charge the struggle, suffering Pull spend more charge.
I phone 1190 - 450 range using the. I can do my work as well as installing and getting faster. Charging time is important, 1190 - 128 range I choose.
Forget! Reduce the processor speed on the phone, when trading amplify şarjınızı. Because it is trying to slow the processor 100% to use and work will be completed on your screen light will stay open late.
6 - When charging the phone's battery Full Fill:
Do not say we already have would remove 100% charge to fill it. Phone software does not fully charge the battery. Leaves a certain margin of tolerance. Here we also benefit by it. In particular I saw that HTC Desire'da tried and successful. Each company's share of each model, it will not stop. But you can be on your left. Does not hurt to try.
Explaining the steps for:
-Phone up to 100% of full charge.
-Turn off the phone, remove and charge the phone.
-Install and charge the phone again, wait until bekleyebildiğiniz. (1-3 hours)
-Turn your phone into the phone, and remove the charge.
-Wait for your phone to do nothing between 2-5 minutes after opening. (Not attached to Sharjah)
-Turn off your phone again and again for at least half an hour into charging.
Remove and use the phone in the normal-charging. The procedure is finished.
This method has been calibrated with the battery is charging and fully. Enough to do this once. And then he goes to full charge.
7 - Special Edition Operating Systems Aim for:
Android users who root for in this Article. Made by the manufacturers of Android devices, phone skins, chargers doing negative effect on life.
TouchWiz, Sense interfaces, such as, the system is more tiring, as they lower the charge time. So we have the benefit of using a pure version of Android.
With pure Android versions like CyanogenMod custom Android versions sure to use similar interfaces. The term of charge with a very stretched. Will be surprised.
Of course, I do not recommend this method to anyone. Aware of the change and the risk of all the phone's Android software will recommend it to our readers.
Suggestions useful to you?

Thanks!!! i will follow these tips :good:

Phone(s) still hot when turned off. Also, wicked power draw.

G'day,
I've had some odd issues with two consecutive Xiaomi phones, and I'm hoping someone here can shed some light on it for me.
With both my Mi Note 2, and now my current Mi Mix 3, after less than a year of owning each one (respectively), out of nowhere, the battery life drops through the floor, the phone gets really hot, and most oddly, I got wicked battery drop while the phone is off (e.g. I turned the phone completely off at 77%, and about an hour later, I turn the phone back on and it's at 43%).
On both phones, I've tried a factory reset, but it didn't work. It was, for all intents and purposes, fecked. At the moment, I'm waiting for the 15 day countdown for my Mi Mix 3 bootloader to be unlocked so I can try flashing the EU MiUI ROM and see if that helps, but that's still a hell of a long time to wait with a phone that idles at 50+° C and has a battery life of about 3 hours with minimal SoT.
I've installed BetterBatteryStats (using ADB to provide permissions), CPU-Z, CPU Monitor and Ampere to see if I could get some more information. I found a few things:
1. Somehow, with mobile data and WiFi enabled, the system was drawing SO MUCH power (reported by Ampere) that it literally wouldn't charge while plugged into a 2A wall port. It was drawing like 1300mA when it wasn't plugged in, and when it was, it was STILL drawing about 130mA, meaning no matter what, while the phone was on, I was losing battery.
2. BBS reported the biggest battery killer was under the 'Alarms' tab, caused by Android, which were "Intent: *job.delay*" and "Intent: *job.deadline*". I have literally no idea what these are, what's causing them, or how to stop it triggering.
3. I've done a full factory reset. The first hint that something was wrong was when I noticed that the phone wasn't charging when it was plugged in and turned on. I did the full factory reset, didn't help.
I'm currently running Global MiUI 11.0.4.0, Android 9.
Does anyone have any ideas? I haven't manually updated anything, I'm not particularly rough with the phone, but for two phones in a row, this has come straight out of nowhere. It's a shame, because the Mi Mix 3 has spoiled me with it's 100% screen real estate (no hole-punch, no teardrop for front camera), but I think my next phone is gonna go with something else.
Cheers.

Update: I've taken a squizz at the Google Battery Historian and basically, I have no feckin' idea.
The best I can get out of it is "Yep, something in the labyrinthine generic 'Android' system is causing it, but good luck narrowing it down or stopping it."
That being said, I've found that this Partial Wakelock is triggered fairly often (1-6 times per minute, give or take): IntentOp:.common.broadcast.BackgroundBroadcastReceiverSupport$GmsReceiverIntentOperation
I have no idea what the hell it is or does, and the only information I can find about it is from developers asking questions where it just happens to be part of their codebase, or a breakdown of how the WakeBlock app works.
It's getting woken up about every minute or so (usually more than once a minute). However, the wakelocks appear to be part of the core Google/Android systems that can't be individually disabled.
I'm still feckin' confused.

Any ideas as to how I'd further troubleshoot? I've gone into *#*#4636#*#* and changed the sort of signal it looks for, but it doesn't appear to have fixed anything.

In case anyone is interested, I've attached on of my Bugreports (from running adb bugreport), which can be viewed through Google Battery Historian.
I'm not saying there's a cash prize for anyone who can tell me what is happening and why, but I'm also not saying that there isn't.

So, I think we have our culprit (maybe).
I have attached several screenshots from a Battery Historian I took after having my phone on all day. The total phone on time was about 4-5 hours with, no joke, maybe 10 seconds of screen on time. Let's go through this absolute bullshittery together, shall we?
Battery - Full Time: The full length of time captured by the Battery Historian/bugreport command. It's in Zulu Time (GMT+0) and I'm in Australia (GMT+10), so the line starts going up at 5PM last night, which is more or less when I plugged it in to charge. You can see, while 'off', it took 16 hours to charge to 100%, and this was from a 'cold boot' (phone is completely dead), so it didn't have any information about what had been running, etc.
Battery - Discharge: The five or so hours time in which the entire battery discharged, starting from when I woke up in the morning and got ready for work. In the Screen row, you can see the small, three-to-four second windows throughout the day that I turned the phone on to check the battery. For almost the entirety of the time, the screen was off. You can see where the line next to Phone State goes from black to navy blue. This indicates that the phone has been put into Airplane Mode - you can see this is also where everything relating to network connectivity or mobile strength completely disappears. You can also see that App Processor Wakeup completely dies here - that means that actual installed apps (including GOOGLE_SERVICES and Xiaomi's preinstalled Facebook app stop sending commands to wake the CPU.
Battery - Cause: At least once a minute, usually more, two things fire that keep the CPU running - Abort:Wakeup IRQ detected during suspend: 999 msoc-delta and Abort:Wakeup IRQ detected during suspend: 663 qpnp_rtc_alarm. I have no feckin' idea what either of those are, and Googling results in either developer guides or threads that lead nowhere. If anyone knows what they are, for the love of God let me know.
Battery - Foreground Processes: While the phone was off, with every app closed, in Airplane Mode, we can see that there are still four apps that are somehow in the foreground: com.miui.mishare.connectivity (odd, since there's no connection), com.miui.securitycenter (which I tried disabling through ADB last night, and it stopped my phone from booting. Oops), com.miui.notification, and com.android.providers.contacts (which disappeared shortly after entering Airplane Mode).
Battery - Video: You can see here, for the ENTIRETY of the time that the phone was turned on, this odd Video row was enabled. There is no other information about it - what causes it, where it's coming from, what 'Video' means, anything.
Battery - 7 Second Slice: This is just a close-up of a seven-second period of time, wherein the above 999 msoc-delta and 663 qpnp_rtc_alarm kept the CPU running six times within 7 seconds. Not a lot on its own, perhaps, but over the course of hours, it clearly causes issues.
I've also attached the latest bugreport where I took these screenshots from if anyone wants to try and make sense of it.

This looks to me like an hardware issue more than anything, what is the idle state of the cpu?
