Obsessed with getting maximum battery usage for sensation

I would like to create a a definitive guide (best Practices) to get the maximum amount of battery out of the Sensation. Coming from a LG G2x I'm finding this battery is actually equal or worse and since rooting and removing bloatware currenty seems impossible, then customizing this phone has to be within the realm of stock apps and settings..
My Experience
Using Battery monitor widget, I'm typically getting -200 ~ -300 mAh usage whenever the phone is being used, it will drop down to -30 mAh at its lowest in idle, but no where like the G2x of 5-10 mAh or -2mAh for Vibrant (in idle)..
My goal is to have this phone last 24-36 hours regularly (if possible) ... Right now I'm getting 12-18 hours, with moderate use.. 20 ~30 minutes calls..
Here are the steps I've tried to improve life, in order or decreasing effect.
General Tips/Steps to imporve
Turn off All Syncing (use power widget to toggle as needed)
Check Settings >> Accounts & Sync >> [disable auto sync]
Set Screen timeout to 15sec
Set brightness to < 15%
Check Settings >> Power >> Turn on most or all the power saving features in this menu.
Remove (or reduce) number of widgets that need to poll data (includes clock/weather, stocks, social feeds, etc)
Turn off Bluetooth, GPS (when not needed, again use Power widget to toggle)
Enable Wifi calling (yes wifi calling saves battery especially in low 3/4G signal areas)
Use camera sparingly (by far biggest battery hog)
Useful apps or widgets
General apps / widgets and tips to have
Add Power widget to home page (for quick toggling)
Install Battery monitor widget for charting battery usage.
Juicedefender or Green Power from appstore and let them help manage power
Things to share
Please add your suggestions, and tell us your
max. battery time, between re-charges.
What are your battery usage stats , what is the biggest battery drain my in screen 60%
your best practices
Lets all share our best practices..

The best things I've found to improve battery life.. Use Juice Defender pro, and set schedules, let it turn off all the battery hogs...
Dam I wish I could remove the bloatware especially that Navigation package.

wow you are severely gimping your phone to get the most battery life. I'm happy with 12-14 hours with heavy usage

Umm... Why exactly do you have a smartphone if you are disabling every single thing that makes it a smartphone? If you want great battery life return the Sensation and buy a phone that does nothing but call and text.
Without disabling anything I am able to get through a 13 hour shift at work with texting all through and internet, youtube, etc during my breaks (~1-1.5 hours) with around 60-70% battery left. Then last week I used GPS with Navigation and screen brightness at 100 for the hour and a half drive home and I still had around 30% battery when I got home. (I was trying to kill the battery on the drive btw). I think all that is pretty damn good for a phone as powerful and with a screen as big as the Sensation.

Sorry but in all due respect this is the dumbest thing I've ever seen. Go buy a feature phone and it'll last as long as you need and do the same thing as your crippled Sensation.

I couldn't agree more. Why buy a smartphone if you are going to shut every single "smart" feature off. It isn't just the OP though. The manufacturers themselves recommend these kind of optimizations in their support pages.
Time to go shopping for a higher capacity battery...

Want the best battery life? Do all that you do... then turn it off for an hour, then on for an hour, then off for an hour, then on for an hour... just keep doing this and you'll DOUBLE your battery life

GENIUS!!!! Or even 2 hours off and 1 hour on! Or 3 off! INFINITE POWER!!!
edit: wow those faces look funny with no spaces between them. I think I'll fix that

I'm just going to enjoy my device features and let the battery drain...

Seriously, why not just actually use your phone and get a spare battery?

Turning brightness to the lowest setting works wonders. That's about all I've done, and I get 14 hours on average ...sometimes north of 17 hours. In general, if I get more than 12 hours out of my smartphone without disabling anything, I'm satisfied with that. 14, and I'm quite happy.
I tried Green Power free and while it seemed to help a bit, the difference for me was just too negligible to bother.

Just enjoy your for for now til you get sick of messing with it. After your sick of it, then start messing with the battery life. That will give something to do.

When I bought Sensation I was simply conciliated with that I will charge battery every single day. That´s it. Don´t buy a smartphone if you want it to last more than 1,5 day. Let´s stop with this battery obsession and start enjoying this great phone.

I tend to use the smartphone on the go, you know like a cell phone, so I'm not always near a charger, and a cell phone (after all that's one of the things a smartphone should do) typically should last a day or two, and I think its possible... but like anything else this battery hungry device can be guided to being a little more miserly in its power consumption... ..
Just looking for advice.. but I'll take the snarky comments...

Honestly if you want a smartphone and good battery life get a BB. That's the only thing I miss about my BB is the 2 day battery life. Honestly these phones are getting more and more powerful by the day and battery technology needs to catch up. IMO I think they should stop cranking out new phones every month and focus on researching better battery technology then crank them out every month It just seems like phone hardware keeps getting more and more power hungry and batteries are staying the same. I carry a little tiny blade folding charger with me or an extra battery. I tried to find the smallest folding charger I could so I could just throw it in my jeans pocket and not even notice it.

to the OP
to the OP, I like you, have not had the initial good fortune of our Sensation-al brethren. 14-17 hours is a pipe dream cuz my phone, after 4 days, BARELY got me 5 hours of light use. Since you actually asked a question, and were trying to be helpful to others who were/are in your same boat, I will give you what I did. I went from 5 - 9 hours without cutting the mythical "balls" off the phone. lol. Use if you like. (taken from another post).
"unless i am misreading, there are a lot of people with great battery life, but there does not appear to be any serious use of the phone. checking fb twice, a few texts, in standby for several hours and two calls will not put any real stress on it IMO and from my experience. So I really don't know if I can use a lot of examples that I am readings as a true gauge.
I waited to get this phone to use it in its entirety. I got frustrated the other day with my first post in this thread because I got hammered on battery life this weekend and I did NOT do anything and I barely got five hours. So I made a few adjustments (detailed below) and i can say that I am on 9 hours/ 20 mins on one charge. I have 18% battery left. My stats:
display 80% (3 hours / 12 minutes time on)
cell standby 9%
calls 4%
phone idle 3%
maps 2%
I text, sent picture mail, used maps (with gps on), had pulse, fb, twitter, gmail and friendcaster sync'd in the background, took several pics and uploaded them, used tap-a-talk to read xda posts, and facebooked. From 5 hours to 9 - I'll take it. I am still not where i want to be, but this is the first day that i felt good about having this phone as my primary device. I hope to get to upwards of 14 hours like i see here in this thread. to get here today i had to do several things to improve my odds.
1. i did not want the signal jumping around so WCDMA only
2. installed advance task killer and set it to "when screen off" and "crazy."
3. installed ultimate juice defender.
4. dropped screen brightness to 80%
I will continue to drain the battery to almost nothing and let it fully charge. I will report back any positive or negative results."

[GUIDE] Battery Management for noobs

Hey guys,
So after many months with the XT720 and alot of flashing and trying to get the most out of my battery, i've come up with a few conclusions about battery life in general and how to extend it. I thought I'd share here. This is mostly aimed at people who are new to android and have not experimented like some of the more advanced users we have on this forum. Hope you find this helpful and please feel free to make additions.
General Battery Info
The XT720 was my first android phone, and I came from a long line of typical nokia phones whose batteries would last for ages. I had no idea the kind of power an android device would use. When I started out using it, i was surprised at how quickly the battery would die. You'd think with advancing software we'd have better batteries but sadly batteries are lagging behind in technology. Generally speaking you can expect the following battery life from your XT720.
Heavy use: 10-14 hours
Moderate use: 16-20 hours
Light use: 1 day - 1 day 12 hrs.
Note: New batteries improve with each charge cycle. It is recommended to go through a few complete charge cycles when you buy a new phone. After that, complete discharges are not recommended and its smart to start charging your phone when it hits the 20-25% mark.
How to improve battery life
1: Battery Calibration
If you've ever flashed a new ROM, you must have noticed a sharp decline in battery performance. This is partly due to old battery statistics left behind from your old ROM. Android is a smart OS and collects information over time. The more you use it, the more accurate it gets. In the same way it collects information from your battery usage and reports your battery percentages according to that. When you flash a new ROM, sometimes android thinks that your battery is 100% when its really lower than that and that causes relative reduced battery performance. To deal with that it is recommended that you use a nifty free app called Battery Calibration from the android market. What this does it removes the old battery stats and allows your new ROM to create its own battery stats. Charge your battery to full, use the battery calibration. Drain once till phone turns off by itself and charge to full again. You will notice a sharp increase in battery life.
2. Battery Managment
We all know that android has its own battery management built in but it usually doesnt give complete information about the phone. For that you need to dive deeper into the settings. Usually if you experience battery drain its because of a rogue app and believe it or not some common apps you wont think off drain unnecessary battery. To see your complete Battery Stats input this code into the dialer.
Code:
*#*#4636#*#*
This will take you to a bunch of options. What you're interested in is Battery History. When you tap that it will show you two drop down menu's.
1) Other Usage
2) Since last unplugged
Other usage shows you how long your phone has been running and how long it has been asleep. Also shows you how long your wifi has been on and running and how long your screen has been on. It is important to see how long your phone has been running. For example if your phone has an uptime of 20 hours and its been running 5 hours out of that. Your run time is 25%. Which is very good. Sometimes an app can run even when your phone screen is off. This will represent a longer run time even when you have your phone lying on a desk or something. See this setting and correlate with the amount you have used your phone. Does it seem normal? If no then use the first drop down menu and select
Partial Wake:
Partial wake is basically, any app which takes your phone out of sleep mode to use the CPU even when youre screen is off. These are apps which need to sync or use the phone resources. In this you will see a list of apps and how much they have caused a partial wake lock. See anything unsual? For me one app that caused unsual drainage was latitute. Yes, i had simply signed into it and i didnt know it was updating my location every 5 minutes. Extreme battery drain for me even when my phone was idle. See which app was draining your battery and either tweak the settings or remove altogether.
GPS, Sensors, CPU:
You can also see these in the first drop down menu. Certain apps like screeble use the sensors alot, and hence cause drain. Obviously games, camera, will stress the CPU. See if anything is causing drain in that and adjust accordingly.
Miscellaneous Information
After you have dealt with rogue apps that you don't use that drain youre battery your battery life will depend on how you use your phone. But hopefull these tips will help you with increasing your battery life. I do have some more information on different settings and supposed battery saving applications.
Autosync: When you enable auto sync, you allow google and other accounts to sync on a regular basis. This is important for people who need to use push email etc. It does not drain battery IF you tweak what you need synced. In google for example you can have your contacts, calendar, google+, google reader, gmail all to sync by default. If you just need email, please untick the rest. This will help you save battery life. Increase your update times for facebook and google+ if you dont recieve many updates all the time or turn them off altogether. If you have many services syncing at the same time you will get battery drain.
Wifi Sleep Policy: This is sort of a hidden menu. If you go into wireless & networks >> Wifi settings >> settings key >> advanced >> wifi sleep policy. This has three settings. Never close down wifi, never close when charging, or close with screen off. If you choose never your wifi will always be on, which will in turn crunch the **** out of your battery. If you use it off with screen off, remember it takes about 5 minutes to turn the wifi off. I personally use the never with plugged in. Its an intermediate. So when im plugged in wifi always stays on and when im not it follows the screen off protocol.
Wifi Vs Mobile Data: Having mobile data on all the time, does not drain battery. The only time the battery gets drained is when the data connection is active i.e you have many apps on autosync youll see your battery going down. If you arent doing anything and your phone is connected to Edge or 3G your battery will drain regularly. 2G networks drain less than 3G keep that in mind. If you are actively using your connection, wifi will take less battery because speeds are faster and you will be using it for a little time. Also your signal strength has alot of effect on battery. If you have crappy 3G signals your radio will actively be searching for a connection the same goes for wifi. That is important to keep in mind.
Control Background data: By selecting this option you can allow or disallow apps to connect to data without any permission. Some apps require this like the android market. If you uncheck this apps wont be able to sync automatically in the background.
Milestone Overclocking: This is fairly obvious. The higher you overclock with higher vsel the more battery drain you will have. Some use set cpu with profiles but I found that if i set the setcpu too low while idle It takes time for the cpu to charge up when i recieve a call or turn the screen on. Ringtones lag etc etc. I let android do my CPU management and its fine. and comfortable setting would be 850 MHZ, 56 vsel but you can change according to your phone usage.
Juice Defender/ Screebl / Task killers:
In my personal experience with juice defender ultimate I found that with the above precautions juice defender didnt make much of a difference and actually used more battery. First off theres an extra process going on in the back. Second activating and deactivating the connection everytime the screen goes off uses more juice because your radio has to search for the signal hundreds of times as compared to not having it in the first place. Screebl is good if you dont want your screen to annoyingly turn off while youre doing something but it surely doesnt save battery life. Task killers are a no no for android. They kill tasks which start up anyways, its better to use autokiller memory optimizer which tweaks androids internal memory settings and allows for more free ram without killing processes without reason.
System Apps:
Some system apps run uselessly in the background specially with stock ROM's this is called bloatware. Remove all unused system apps with titanium backup to stop them from running in the background for no reason at all.
A final word
Finally after all this tweaking, just use your phone as normal. Dont worry about the battery all the time checking how much its drained, itll mess your head up and make you enjoy your phone less. Battery temperature also changes battery life. Keep your phone out of the sun or in hot places.

Thanks, good article.

Very detailed and useful

Thanks for this interessting article!
Could you make a list of the bloatware that can be safely removed?

I figured this would just list all the usual stuff I've heard. I'm glad to say I was wrong! A bunch of useful info here I now plan to put to use. Many thanks
Might want to mention the display being the biggest drain of battery on this phone. Setting it to automatic brightness or lower will increase battery life. I love the screen at full brightness so I don't really follow that, but for those looking to squeeze some extra time and don't mind less brightness...

Thanks guys, glad you people found it useful.

Yes! Can't believe I missed that one out. In the start id use the lowest brightness setting, which would be fine indoors. But outside it was impossible to see the phone because of its insanely reflective glass. Since we have an ambient light sensor I use it on automatic and it does a good job. Full bright strains my eyes abit thats why I dont keep it on full bright So for people really wanting to save the juice you can keep your brightness on the lowest level. Also when you take the phone out of your pocket and use it, its better to put the phone to sleep with the power button than let it timeout by itself. Those 10-15 seconds for each time you use phone count towards many minutes of unused display time in the end and does make a difference.

This is a very gd post with lots o useful info!! ok i have a qn, is using the phone a lot while the charging good for the battery? And if u let the battery charge even though its already 100 percent for an hour good? srry if it is noob qn...

1. Using your phone while charging does not affect your battery life, and is neither good nor bad. It is perfectly normal to use your phone while charging and is sometimes recommended while doing battery intensive tasks for example navigating while driving, wifi tethering, playing memory intensive games and finally outputing video through HDMI.
2. Overcharging was a phenomenom is older lithium ion battery. New batteries have bypass circuits. So when your phone reaches complete charge, it does not charge any further. So you should not be worried about overcharging your XT720.
Hope this helps.

Excelent article and good quality info. Thanks and best regards!

awesome article! Great information. Thanks a lot for putting that together. I have already started using a few of the tips mentioned.

u da maaan dude, thanks for a very detailed and informative article

Advanced Tricks for Saving Battery (it Works)

EDIT: Last Update: 10th Sep 2011 with New INfo (trick no.7)
Advanced Tricks for Saving Battery
The following tweaks can greatly save battery if you done it right. But bear in mind that risk are relatively higher since its involve those deep system components.
If you know what you're doing, there is not much to worry about.
Note: I will not responsible for the any damage of your device
My Result:
Before: After moderate usage of 20 hours, Battery Left 30% - 35%
After : After moderate usage of 20 hours, Battery left 70% - 75%
Note: Battery Usage is very subjective matter. The numbers here is not trying to give you an exact calculation, it just trying to give you a feel of how the battery saving. But i have try my best to be consistent on the usage pattern, cpu loads and temperature to do this comparison. Of cause, you might discover different result on your device. With different ROM, kernel, radio, usage, screen brightness, all the other factors come into play, the result would varied.
Kindly please post a feedback on how it works on your device>
1. Use Undervolted Kernel / ROM
- Undervolted means that your device will use relatively less battery to give the same CPU frequency
- (e.g. normally CPU run at 1.61ghz @1350mv, after undervolted it may require only 1275mv at the same frequency)
- Tested on my device, it is the most effective tweak to increase battery life (I reduced -100mv at most of the CPU frequency (except 1), give me about 30-35% more battery)
- Because the undervolting value is varied depend on the ROM and kernel, so no point i post all the numbers here. (PM me if you need the list)
- Ask at your respective ROM thread for the availability of undervolted tweak
- If you wanted to try to change the undervolting value, i recommended to use OC/UV beater2 http://forum.xda-developers.com/showthread.php?t=1207546

}
- Because the tool have ease-to-use interface (no need use terminal emulator), just few taps will do.
- Most importantly, we can test new UV value with "Temp Activate", if the device freeze, just restart and it will go back to the last good state (last best config for you, instead of kernel's default value), and no need to flash the vddreset.zip / other reset.zip
2. Use "GSM auto (PRL) to save more juice while still connecting through 3G
- in the phone setting>wireless and network>MobileNetwork>NetworkMode
we are only allow to choose GSM only/ WCDMA / Auto between two
- but if you use type "*#*#4636#*#*" to phone Information, you can choose more type of networkmode. It is claimed that choose "GSM auto (PRL)" allow you to save more battery (cell standby) while allow you to connect to 3G network.
- This might somehow depend on your carrier / provider
- Please provide feedback on this. THanks
3. Try out different CPU Governor
- nowadays a lot of ROM have advanced CPU governor like Smoothass, Smartass, Interactive, etc.
- Try different combination during wake up and screen off to look for the best setting that let u save more juice
- This are my settings:
Governor during awake = On Demand
Max Wake = 998mhz​ Min Wake = 122mhz​ Governor during Screenoff = PowerSave
Max Sleep = 307mhz​ Min Sleep = 122mhz​ - NOTE: if you put min sleep too low, there is a chance that you device might freeze and won't wake up!
- I personally recommended "DaemonController" from Sybregunne for controlling the CPU governors and frequencies. It is a ease-to-use, yet sophisticated enough for the purpose of OC/UC. It is my favourite OC/UC controller since it released.
- DaemonController is a smart tool that it will bypass virtous daemon, and use direct frequency if we choose governors that is incompatible with the virtuous o/c. Hence, only 1 deamon is run which is more efficiency.
- Refer to the original thread here for more details: http://forum.xda-developers.com/showpost.php?p=16726715&postcount=2
- Quoted from original thread: "It is a Graphical tool that allows users to change andrev_oc/virtuous_oc frequencies and governors without having to reboot their device. Confirmed to work on Android Revolution HD 6.1.0 and a lot more ROMS.
4. Use AutoKiller Memory Optimizer
- This tool is different from other app killer
- It fine tunes android systems inner memory manager to keep your device fast over time.
- As a side effect it also lowers battery consumption.
- At certain free memory level (e.g. 250mb), the android os will automatically close those apps not in use (according to original android os logic)
- The lowMemoryKill level can be modified to suit your style of usage. It is to find a balance point between "not killing the apps you're need" and "sufficient free RAM to avoid sudden out of RAM / Laggy ".
- What i experience before is that these values are set to be too low. It keep most of the apps opened in background. So we can use the apps much faster and consump less cpu. Result: we have lower free RAM. The tradeoff: When I open heavy game, I experienced run out of RAM (it tell me not sufficient RAM to run).
- When the values set too high. It will kill the apps in background faster. So we will spend more cpu, and slower to reopen it. Tradeoff: you will have alot of free RAM back there. But for what?
- Therefore, it is to find the middle point that satisfy both ends. Generally, users with more apps better off with lower lowmemorykill value. Users with less apps (always switch between fews app only), are better off with higher lowmemorykill value.
- MY case: I only have 25+ apps installed. and Only use few apps (other rarely use). THis is my setting (in Pages): 3072, 8192, 16384, 50688, 58368, 76288. I have experimented with many values for 3 months. Just 1 month ago, i found these value suit me very much. It keep balance between the two tradeoff mentioned. Maybe you can try to figure out your own.
- Generally, we play with the last 3 numbers only. The first 3 numbers is related to:
(Foreground app)
(Visible app)
(Secondary server)
Which offer no significant benefits if we kill them.
5. Use Autostart
- Instead of closing them, it would be better if we don't let the app start from the begining
- You can choose to disable those app that u feel unnessary, so that they will not run during your phone startup
5. Check your Battery Consumption
- Download "Current Widget" or "battery monitoring widget" from market
- these apps will monitor your battery usage and recoded in a log file
- This is the normal consumption rate (varied across ROM, kernel and CPUI frequency and other factors)
Sleep/ScreenOff Consumption: 2mv - 8mv
WakeUp Consumption (no wifi, just use local apps, no gaming): 150mv - 250mv
Gaming consumption: about 300 - 400 mv (varied across diff games)
- To be comparable, it is suggest that you try to compare the consumption rate with your friends with same ROM, kernel, radio)
- With the monitoring log, you will able to notice adnormal peak / adnormal high drainage easily
6. Use "Battery History for GingerBreak" to check what running in background (Especially thanks for Saluco for this useful way to check battery drainage )
- this is a free tool can be download from xds forum http://forum.xda-developers.com/showthread.php?p=13328125
- Go to "Partial Wake Usage" to see what apps running when your device is sleeping
- Please "thanks" the developers of the apps for creating and letting us use his useful tool
- Give the screenshot of "Battery History for Gingerbreak" to the community of your ROM, this will give them more clues for them to help you
- For consistency, please monitor your usage for at least 3 hours (@ frequency 1 - 5 minutes) in order to have sufficient data and reliable readings.
7. Disable "Receiver" of application using AutoRun Manager (Really for Advanced User ONLY)
- Receivers are the "condition" where if it is fulfilled, the app will be executed
- For stance, Google Map has 8 receivers. Either 1 of these 8 conditions is met, google map will be open and run automatically.
- Now we actually try to disable this autoRUN by disable the "receiver" = means that even if the condition is met, the app won't run
- TO do this we need donated version of AutoRun Manager (available in market) to do this, go setting enable advanced mode
- Go second tap of the menu (advanced menu) to disable the receiver of particular app
- It is HIGHLY recommended to disable 1 receiver at 1 time, so that you can know the impact and trace back to the receiver
- you might get confused if you disable too many receivers at 1 time
- WARNING: ONLY disable those receiver that you know. DIsable system's receiver will make your system instable. So better only disable the user app.
- WHY IT IS USEFUL? Example: i used "Battery History for Gingerbreak (tip 6) to found out that "Facebook for android" is locking my device from being deep sleep (as it shown as high minute usage in the "partial wake menu"). Then i wanted to disable the feature of the that keep my device awake. THen i disable the "awake service" receive of it. Then it will help to save more battery by preventing those app that run automatically when certain conditions are met (example: Wifi-on, location changed..etc_

(The content is talking about HTC Desire HD, but the tricks can generally apply to any other smartphones, Hope it help you~)
Well it’s been 7½ days since I reviewed the Desire HD in which I said I didn’t want to comment on battery life until I’ve used it for 10 days. Tomorrow morning at 10am will be the 10th day, but I’m ready 14 hours early!
I’ve seen a lot of talk on the internet about terrible battery life, I’ve even experienced it myself (10% per hour on standby) but not wanting to give it a bad name without being sure, I’ve waited. I can now declare – the Desire HD does not have a battery life issue!
Read on after the break for how you can make yours last 24 hours on one charge!
Let me explain first of all, why I don’t think there is an issue. My Desire HD, last night and today, has shown better battery life than my Samsung Galaxy S and Nexus One ever did. It will probably continue to improve for the next week too.
Yesterday, after 10 hours of medium to light use (screen on was 40 minutes), I was still at 59% battery.
Today, I’ve been off for 12 hours and I’m still at 48%. The screen has been on for 50 minutes, 30 minutes of streaming music via bluetooth, 1 hour of podcasts playing through my earphones and a few text messages. Generally, on standby (and not being used) on 3G while at work, it was only using 2% an hour! I’m not [/B]sure any Android phone has ever managed that low consumption for me.
I don’t know how HTC have managed it from a 1230mAh battery, but if anyone manages to produce an ‘extended’ battery that fits, this thing could last a very long time. As for what the Desire Z might be able to do, wow!
So, what have I done to get this? As well as the usual tips I’ve given, here’s a few more for your Desire HD -
Remove apps you don’t use. You’ll need to root your device with VISIONary and then remove system apps like Flickr, Twitter, Stocks, Peep, Gmail and Friend Stream using Titanium Backup.
Syncing kills! Go to Settings -> Accounts & sync and see what apps are set to sync. For me, a big improvement came from turning off syncing my Facebook ‘Live Feed’ (this seems to turn back on at reboot). Also, only have one of the two Facebook apps syncing at all. For me, I stopped HTC Sense, News and Weather from syncing. If you really want these, maybe just drop their frequency an extra hour or two.
Lower e-mail checks. I have 4 e-mail accounts that K9 Mail checks for me. Like the other syncs, I dropped them from 15 minutes, to 1 or 2 hours, 4 for the less important one. Definitely don’t use the push e-mail setting on K9.
Try different connections. Go to Settings -> Wireless & networks -> Mobile networks and change Network Mode. For me, for some reason on Orange in London ‘WCDMA only’ works the best for me.
Calibrate. After 7 to 10 days use, calibrate your battery and you should be good to go, simple as that!
**ADDITION** Once in a while (if not always) try charging via USB rather than mains. It has been reported this is better for the battery and will actually provide better life from one charge. I can’t necessarily say this claim is true, but I have often seemingly got better life from a USB charge. Try it!
Bear in mind, there are people reporting much better life than I get. Some say they can last over 40 hours on one charge.
Also, make use of the ‘Power Saver’ in Settings. I’ve put mine at 30%. When this kicks in I tend to find battery consumption might even drop to 1% per hour, which means it may be possible you could last for 3 days on one charge! I can’t wait to see what happens when we get proper root and can use custom ROM’s!

Not really sure anything here is new information...

Cheers, I'll try a couple of these.

How about putting your phone into Flight mode while at work.
I, for my part, get my mails to my desktop machine anyways and i like the fact, no one can distract me while I'm hacking in a gazzillion lines of code.
If it's important my lazy colleagues can use their legs and walk into my office.

flight mode is as good as switching off your phone

My battery already goes down like 1% every hour when the screen is off. So it's fine to me. It's only when I'm actively using WhatsApp, Facebook and Twitter that it goes down faster.
Main killer of the battery is the screen. The screen with high backlight burns through it. While idle it hardly drains.

thanks for this

I use Juice defender beta with ultimate features and i did calibrate my battery. It's 1:26 AM and through moderate to heavy usage i'm still at 41%. It still has a lot to do with your CPU speed (over/under clocked), ROM, Radio and kernel. I'm CM7 Lordmod's CFS kernel and the latest Radio from AT&T Stock (I have the Inspire the Desire HD's identical cousin.) and a RIL to match. Oh and I'm Overclocked to ~1.2 GHz using the ondemand governor.

Juice Defender of any use?

Is there any practical reason to install these battery-saving apps? Most of them I have seen just tweak the menu options of your phone you can already access manually and give no additional functionality to the phone itself that you couldn't already do.
Is this any different? Or will it just sit in the background consuming battery life itself just to run its "function"?

I've always had horrible time with these "battery saver" apps
Just let android do its thing
Turn brightness down, turn off GPS, BT and 4G/LTE when not in use and lower the intervals of background updates (and by that i mean turn the time up higher lol) on apps and your battery should last longer

I used Juice Defender for awhile and realized it wasn't what I wanted. I tried Easy Battery Saver and that really helped out a lot.
What it did was to disable all internet, GPS etc when not in use or screen locked. It really helped out a lot in helping to save battery

I don't find they help much anyway and will just drain your battery faster, I think they're kinda designed for the average user who keeps everything on and don't know how to do all the things alot of us who are more better with Android already do.

All I had is bad experience with battery savers and they drain alot more then they save for me plus I already turned off all online stuff like Wifi, bt, 3G, mobile data etc.

Juice defender pro is doing a great job for me. Recommended! No joke at all.
Also it has come to my attention that it has a feature of learning. The more time you have it in your phone then it will do a better job to save you battery. Also alot of settings to do depending on how much juice you want to save.
Sent from my GT-I9300 using xda premium

On my phone, I used to run Juice Defender all the time. After awhile, I realized all it was doing was turning 3G off when my screen was off and turning it back on when the phone woke up. Since I wasn't necessarily using 3G every time I woke up my phone, I got into the habit of just turning 3G off and on only when I need it and stay on Wi-Fi as much as possible. After uninstalling Juice Defender and growing accustomed to found this, my battery life has improved at least 3x and I have never looked back. Just my 2¢.
Sent from my AOKP Swagged Out Nook Color

Yep, I also stopped using JD a long time ago. There are much better ways of saving battery than adding one more application - if you know what you're doing. Using JD is less work, but it's not the best way.

If you are toggling wifi, data, gps etc by your self you dont need JD. I used it sometime but I have habit to control all toggles myself and just found JD interfering with my choice and it shows it saves some 1.8X battery but I didnt find it that much.

I have tried many of them; in my use/ my phone (Nexus S, unrooted, stock JB) is Battery Stretch far the best, really almost doubling battery life.. JD, etc did save some juice, but far less, than Battery stretch. Just my 2c.

Personally I'd call my level of use on Android to be near expert. Not really a developer here, but I'm a very proficient user.
I'd say Juice Defender is totally full of crap.
So what can it do? It turns off "3G?" I swear this misnomer came from the US or something. We somehow equate 3G with data. I thought it meant it would throttle me back to 2G while the screen was off, but all it does is turn data off. Now here's a question: What the hell is the point of a smartphone with its data off? If you like social networking, email, communication, you WANT those notifications to come through. So what does turning data off while your screen do? You might as well turn off data manually and then turn it back on when your screen is on.
Furthermore, if you're interested in saving battery, use wifi in places where data sucks. The minute you turn wifi on, data is switched off. You don't need Juice Defender to figure this one out.
I can see 2G/3G auto toggle being useful, but this can be installed separately as the 2G/3G toggle app for CyanogenMod.
You should be able to tweak your battery to max it out without the use of any 3rd party apps or rooting or anything like that. Tons of newbies install a bunch of apps and as a result here's what could be draining for example:
- Google+ instant upload
- Dropbox instant upload (wow way to duplicate Google+ and effectively double your data use and battery consumption)
- Pulse news sync
- Google currents sync
- Gtalk 24/7 push
- Google latitude
People always say turn off GPS but I ask why? Are you leaving your maps on for 10 minutes at a time? I use location services a few seconds at a time. Show up to work? Checkin at foursquare. Walk into a bar? Checkin to foursquare. About to go home? Take a look at Google Maps. All that takes 1-2 minutes tops. How much battery should that even consume? 1%? Turning off GPS means what? I consume 0.5%? Woohoo. BIG SAVINGS there bro. Furthermore you gotta remember to turn it back on if you ever want to use navigation, and if anything having GPS accuracy helps when using location services like for Foursquare of Facebook checkins. You could find that venue as one nearby rather than scrolling around trying to find it because the cell tower puts you a mile away. You save time like that too.
Screen is the big one. Autobrightness should work well on most stock ROMs and even most stable ROMs. IF you're using your phone outdoors expect that screen to drain like mad, but indoors it should be fine.
Honestly, JuiceDefender accomplishes its task by crippling your smartphone. That's not what a smartphone was built for. You should be able to use all its features and get through a day unless you're on your phone 5 hours straight surfing. Then expect it to die soon. No juicedefender will save you there.

I think the point of JD is that you don't need 3g data on all the time, you can set it to enable 3g data every min/5 mins/30 mins/hour etc for a set time, if background processes are sycn'ing (gmail, facebook, twitter etc) it will wait until the sync is done, this means its up to you when you sync data, I sync evey 15 mins and it works really well. When you switch the screen on, data is automatically enabled, i have set it to use wifi when in range, or 3g when out of range (again its automatic) JD does save you battery and it does it all on its own, millions of downloads can't be wrong
Sent via TCP/IP

And that's exactly what Battery stretch does - with a much smaller footprint/memory/battery load than JD!
Just give it a try - I have tried all of them- and judge it for yourself

Another one to check out is 3GBattery, very basic but maybe that was the point too

Juice Defender is a fickle mistress. It does what you want, but it can get in the way. I use it when I know I'm going to be away from power most of the day and I either forgot my Sparq or it won't be practical. When properly configured Juice Defender bloody works. I usually end the day with a 2.4x boost when I use it. Normally my phone needs a pick-me-up after about 8-9 hours. With Juice Defender I had 35% left after an 18 hour day. The only difference was Juice Defender and using Screen Filter to drop the brightness. Had about 3.5 hours of screen on time.
Juice Defender's bread and butter is its data toggle tool, and there are some things to keep in mind with it to make the most of it.
When the data state on the phone goes from not connected to connected programs that can sync want to sync. This adds a lot of data use and cpu cycles. Because of this I've used the Application Specific control rather than having data toggle on at screen on/unlock. I don't want data coming on because I reply to a text. Data comes on when I call up an app that needs it, and data runs in the background for Music and Spotify only.
There's the argument of crippling a smartphone, but honestly, 99% of communications that come over the data network aren't urgent. Urgent communications are calls or texts. No power is more crippling to a smartphone than no data.

It's an absolutely fantastic app, but the memory footprint is huge! Even really fast devices like my evo lte slow down a little over time

[Q] How to Get Amazing Battery Life

Hey everyone,
Lately I've been in the works of trying to get better battery life, as I only get about 2 - 2.5 hours of on screen time. I've seen other users get anywhere between 5-7 hours. I do use facebook, and have uninstalled the official facebook app for the friendcaster one, but have yet to still hit anywhere near that amount of time.
Out of curiosity, and hopefully future reference for other users, what are some great ways to boost battery life? Do you use apps? Uninstall software? Please, do share!

Manually controlling screen brightness was the biggest increase for me. The other one that helped was 2g data when i turn off the screen.

Freeeeze apps with Titanium Backup. You wont miss anything neither you loose perfomance, no you gain.

Change notification updates to suit your needs. Stuff that you don't need to know right away, lower frequency or turn to manual. For instance:
- Change weather updates to every 1-2 hours, unless you really need to know that it changed by a couple degrees as it does.
- Decrease facebook notifications (big one. If you use it a lot, then keep it high, but realize that this WILL drain battery.)
- Manually update stocks (again, if you don't need them instantaneously)
- Blog & News apps usually set notifications on by default, disable or lower frequency on them
- Lower screen brightness
- Turn display to auto sleep 30sec-1min tops
Note that while some of the notification controls can be found within the system settings, many apps will require you to go to their individual settings to adjust them.
All depends what you do with it. Navigation, internet, talk time and intense games all suck up more battery. That doesn't mean you shouldn't do that stuff, but it's just the way it is on any device.

Simple, root and install CPU sleeper, that should give u a lot of battery life.. at least that's how I do it and today I unplugged my phone at 10 am and its 9:25 and I have 65% left

Almost all of em are running on custom roms I beat and I'm the one you said that with 5 - 7 hours screen time everyday. There are many things to do to maximum the battery performance and first thing is root and unlock your phone and flash a custom rom. If you are on stock rom, it would be almost a no go.
1. Flash ViperOneS 1.2 rom or One maximuS V2.5 rom, they are the best sense based rom with the greatest battery performance I've seen.
2. If you don't need sense, flash cm10 or aokp. They should give you more battery because they aren't as resources hog as sense. However, you couldn't use sense UI and access to the dedicated image chip in camera.
3. Turn the brightness level down to as low as possible, this is the major battery killer.
4. Switch to 2G when you are in standby mode. Disable fast dormancy, it will save you battery in standby mode at the cost of connection speed when you surf web it will be slower but it does save you some battery in standby status. You can disable it in ViperOneS's tweaking but you'll have to do it manually in all other roms but that is very very easy. Personally, I let it on because the 3G speed isn't good in Hong Kong, too many iphone/android everywhere here, over crowed. In every street in HK are messed up by SGS3/Note/Note2/Iphone, think about how horrible it is.
http://forum.xda-developers.com/showthread.php?t=1684604
5. Turn off wifi when you don't use it, disable max performance in wifi setting. Turn the auto-sync off when you don't need it too.
6. Just remove all apps and bloatware you don't want. When you flash ViperOneS/maximuS 's add-on, you will have a list to do it.
7. Some bloatware will still be there after flash the add-on. You have to download systemapp remover to del those apps.
8. Some apps like to run as services mode and they drain battery in background like youtube, google map, playstore. You need to download AutoStarts and force them to disable as an auto-startup services after bootup.
9. Download Systempanel and check any non-system apps running at services mode in background. Force them stop in control panel. I only have four non-system apps let them running as services like whatsapp.
10. Don't run too many widgets, I only have two widgets on. Don't use 3D wallpaper.
11. Use opera mobile to surf web. The stock browser and chrome should faster but sometimes they drain battery real quick.
12. Turn the cpu mhz down when you are just doing some normal/easy works because the stock kernel has very suck governor performance(only ages governor: on-demand, save battery, max performance) and drains battery fast. Turn the cpu mhz back to high level only when you play games, this will save you great battery. Don't worry S4 CPU is still very powerful even you set it to half speed. You can flash custom kernel if you don't like to turn cpu speed up/down, they introduce more efficiency governors to handle it automatically but all 3rd kernels are likely to have some bugs at this time. There aren't many active developers out there.
13. After a heavy or long using like a full battery cycle, reboot the OS to clean up the cache/memory leak.
14. Use nova launcher or apex launcher to replace the sense launcher.
Well, I basically do ALL the stuffs above and got 5 ~ 7hrs screen time. Today, I do surf the web like mad(4hrs), 1hr 720p movie(software decode in MX Player as it's a rmvb movie), 30mins+ music with poweramp. Guess what? I got exactly 5hrs screen time and 1% battery left when I get back to home, very lucky though. I think my usage is a bit high today, normally I have 6hrs screen time average.

A lot of people on stock ROMs can get that sort of battery life too.
This is mine on stock:
http://forum.xda-developers.com/showthread.php?p=27010378#post27010378
Also wrote a quick guide, pretty similar to the above:
Terminator19 said:
Leave "best wifi performance" turned off.
Disable any apps that you don't need in settings>apps>click on app>disable at top right
Don't have weather etc. syncing every 30 minutes etc. set to something like 2 or 3 hours.
Manually control the screen brightness as auto makes the battery life worse, install qbright from the market and set a gesture so when you swipe up or down on the homescreen or dock icons this app is opened like the below:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I have it set to currently; night is 0%, indoor 30%, outdoor 50% and sunshine 70%
Keep wifi on as much as possible and set to never sleep
Keep GSM mode selected instead of WCDMA in mobile network settings as one; the voice reception is stronger and better battery life even when connected to wifi I found.
If you aren't going to be using any internet at all for quite while (meaning no need for weather, emails to sync etc.) then turn wifi and mobile network data off.
Only enable WCDMA when you want to browse or stream something (only when wifi is not possible)
Don't use any form of a task killer, if an app isn't responding just use the built in one.

WOW! Thanks guys! I'll definitely be trying these tips today.
Lets keep'em coming!

I'm running CM10 and all I did was lower my CPU clock to 1134 and I get great battery life. I also try to keep my wifi off as often as possible. I have auto-brightness and auto-sync on and usually get 6-7 hours and don't have to charge it all day. I prefer being able to use the better governers on top of the decreased frequency, but I haven't been able to get the Fusion AOSP kernel working on CM10 for quite some time.

I've always thought about under-clocking my CPU. I'll give that a try too. I'm sure i don't need the full 1.5ghz. I'll play around with them and see which will fit my needs .

My battery lasts twice as much just by turning the mobile internet off. I turn it on only when I need to surf the web/sync my apps and turn it back off right after.:victory:

Change governor to smartass2 and set your max CPU frequency at 1ghz. Also you can install app called llama for profiles switching and battery saving.
