Let's start off with calibrating battery tips. What do you think you need to do to properly calibrate a battery?
Here is what I think is required:
1. Charge phone to 100%
2. Discharge to 0%
3. Let phone sit for 5 minutes
4. Plug it in without turning the phone on
5. Charge without break to 100%
6. Repeat 2-3 times

No problem. Please post advice about batteries if you have any.
For non rooted phones, users should lower the screen brightness, screen uses the biggest amount of battery.
Gps, haptic feedback, data should be turned off when not in use.
Also users can install auto task killers that auto kill processes/apps thus saving the battery.
With android assistant +18 app you can also do that and also disable the start up of certain apps, so they aren't on since you turn on the phone.
For rooted phones, Greenify app can lower the battery battery usage by fiddling with app processes.
Ill edit if I rememember anything else.

Thank you for the advice. No offence, but I heard task killers are bad. I heard that Android kills task in a more effective way if it needs more memory. I also heard that killing tasks require battery to do so. Is this true?
Task killers are great if you have a lot of running apps, they work good for me, set them to kill every 30 mins and you dont have to worry if you left an app running in background.
When the battery life is in question, the little things also matter

Your right task killers are pointless on Android. When you kill something android normally just restarts it (depending on what it is) It also takes more to restart it then it does to leave it be.

Take a look at Greenify app. It hibernates your apps on the fly. Meaning they're frozen until you need them. It prevents power drainage done by Facebook or Maps, and others badly written, yet useful from time to time apps.
It really does make a difference on your battery life.
On the other hand task killers are useless since Jelly Beans, as it handles memory management in other way. Low Memory Killer values are dynamic, changed by OS according to your usage odd the phone. Killing apps does nothing else but force them be run again according to their schedule, which results in bigger battery drain and to top it all task killer needs power as well.
Just my 2 cents from a noob.

It does sound like a good battery life, but I bet if would look at your wakelocks you'll find Facebook among top of them. Even if you use it just from time to time it wakes your phone to often in my opinion.

Here is charging tips. Please correct me if I am wrong.
NORMAL USE
1. Charge when >50%
2. Charge until 100%
HEALTHY CHARGE (Every month or so)
1. Discharge to >20%
2. Charge until 100%
Make sure to take your case off, it will generate extra heat that is bad for your battery.
Thank you for contributing everyone.
Follow the method of full charge and full discharge. Don’t put your phone on charging when there is the battery remaining it for another few hours unless it’s very important. Charge it when your battery is about to get totally discharged and when you put it for charging, let it get charged totally.

Is it not bad to allow your battery to run down to 0%?
Only i've read of certain handsets not being able to boot due to this.

Its actually healthy if you get it to full charge after that, laptop batteries are also kept healthy with that method.

I was wondering if there are any good battery savers for the samsung infuse4G. i have the cpu tuner and not 100% sure how to use it. i have downloaded a half a dozen task manager/killers from the market. as of now i have "advanced task manager" killing every 5 min. i have some apps ignored. on the cpu tuner i messed around with it last night and got all things working fully on it. now it says everything but the power save and performance working. if there is anyone that uses this please let me know exactly how to use it. still a little confused about some settings. and if there is anything else i could try, let me know, and how to use it. Also i am currently on a different rom "bionix 1.2" i have Bluetooth and WiFi and all that normally off. the brightness is lower than 10 % all the time.
First, you posted this in the wrong section. Should be in general.
Second, setting your task manager to auto kill apps will decrease your battery life. On older versions of Android it may have helped, but on Froyo and newer some apps are loaded automatically in the background so they can open quicker when you access them or so they can receive notifications. These apps that are loaded in the background generally aren't doing anything at all and thus aren't using any extra battery. If you set your task manager to automatically kill them they will just keep loading, being killed, loading, being killed, etc., which DOES drain your battery.

This is what I do and may or may not matter but I get great results. Before I flash a ROM, I make sure my battery is charged to 100%. Once you are done flashing the ROM, calibrate the battery by:
- Charge to 100% turned on. Wait for the beep and notification that it is fully charged.
- Unplug and turn the phone off. Once off, plug in and let charge until you see 100% on the screen.
- Unplug again and turn the phone on. Once fully loaded, plug in and charge 100% again.
- Power down into recovery and delete Battery Stats under Advanced menu then reboot.
- Power on and charge to 100% again.
Usually it takes a few days for the battery to settle in but following these instructions, I get instant results.

I just did this. I have the infuse tomm with community voodoo and the battery goes from 100 to 60 in 2 hours with moderate use. I am a heavy tester and the brightness is almost 0 I'm not sure what I am doing wrong
Sorry I was on a phone when I typed that. Meant to say. I have the infuse the rom and I am a heavy texter. Have the brightness on almost 0 and I have CPU tuner going and task manager killing everything except 6 things every 5 min and when the screen is off. I can't figure out why my batter is dying so fast. Like it'll die with moderate use for around 5 hours. even if I have the screen off it'll die. I have some apps frozen with this bloat freezer.

Did you read post #2 here http://forum.xda-developers.com/showpost.php?p=14885241&postcount=2 Auto killing some apps will drain your battery faster than leaving them running. I didn't know this until now. So I have deleted all taskmanager apps I was trying and will only use JD without any task killing functions enabled.
I only use Advanced Task Killer to manually kill tasks. I also am careful not to install tons of stuff at once - that way if I get a "bad app" that eats battery I've got a good guess what the culprit is.
The autobrightness/swipe-brightness trick works great.
Kill WiFi if you're not using it.
The new Infusion undervolt kernel is awesome. One day I was at 50% at the end of a work day (admittedly WiFi was turned on but not in use for a good portion of that), the next day I was at 79% at the end of the day. (WiFi turned off + Infusion kernel set to undervolt with no overclocking.)

Task killers don't work in froyo and above, because google disabled them.
They're bad. Period.
The one that comes with it is best to use sparingly.

Wrong. Google did nothing to disable them, they just reduced the need for them and the effectiveness of them against many apps.
However, some apps just need a good killing when you're done with them, like Facebook. Facebook seems to inhibit a lot of power management functions from working properly... On my old device (AT&T Tilt2 running XDAndroid), Facebook was the #1 culprit as far as wakelocking a device.
However, as I said - autokillers are BAD, and randomly killing stuff unless you KNOW it's a pesky app can be bad.
use setcpu for profiles, e.g. screen off 100mhz - 200mhz with 100% priority.
running Infused 1.5 with Infusion 1.5 kernel (note that the UV in Infusion 1.5 is broken atm)
screen on auto
wifi/data on 24/7
made couple phone calls
navigation used for ~30 min
online surfing facebook/banking
work e-mail refresh every 5min from 7pm to 10am.
15% after 29hrs use. (is that good?)

No, you are, as evidenced by you linking to an article that is almost a year old without checking to see if anything had changed since it was published. Advanced Task Killer is more than capable of killing apps - Google may have disabled it temporarily last August but it's been working since March of this year at least (That's when I first got a Froyo device). As I stated - some apps (like the Music app) are set up so they auto-respawn when killed, but they CAN be killed (However, autokilling them is going to eat your battery). A number of apps also do NOT auto-respawn, as I said before, Facebook is one example, and it's an example of an app that is notorious for eating battery and needing a task killer to take care of it.
Now the way sleep and power management works on our Infuse might mean Facebook is less problematic on our devices, but in the case of XDAndroid builds on MSM devices, the Facebook app clearly would prevent the device from entering deep sleep in a timely manner, causing it to eat battery like crazy. Killing it with Advanced Task Killer would fix the problem.
Edit: As another example, it can also kill the Browser process successfully, which is great for when the Browser process gets wacked out. I haven't had any issues with the Browser on the Infuse, but it could easily make the whole system extremely sluggish on XDAndroid Froyo builds.
I'm currently running Valhalla final rom and it drains my battery very fast with even minimal use.. I aslways have GPS and wifi off. Always quit all my apps and free the ram when I'm done... any good roms out there with good battery life?

I get 2-3 DAYS with valhalla final, so I'm not sure that swapping roms will change your battery life much. You can try one-click gremlin remover before you flash your next rom of choice though.
also, do you have any apps/services that run in the background, like facebook?
+1 to Mike
Alex - there are several recent threads tegarding battery life in the Q&A section. Browse them and see if you can learn a few things how to improve battery life and what the big battery drainers are.
All the ROM's, for the most part, have the potential for great battery life if you use them correctly. WiFi, Sync and GPS need to only be on when you need them. Many apps sync on their own - adjust the sync intervals on them. Use Gemini App Manager or AutoStarts to disable autorun scripts in the apps. Adjust screen brightness. Any data hungry apps (i.e. music streaming, Netflix, etc) will drain your battery regardless what you do. Undervolt with Tegrak Premium. Minimal widgets on home screens.
It is not the ROMs - it is how the end-user uses the ROM and their phone.
Turn off data and background data, until you need it. I get over 2 days sometimes depending on usage

Im noticing a big difference in battery life from stock gingerbread... I know for a fact that my battery is good because i was always able to use it fully for one day.. i dont charge my phone often to keep battery health in best condition I charge only when its super low.. and once in a while I let it die completely then recharge it fully
I even see a better life on icbinb rom than valhalla.. just wanted to see if anyone else notices the difference guys
You saw Mike says he gets a couple days on Valhalla. Try the Gremlin Remover. Do everything the thread says. It is effective.

Stop doing this. Li-ion batteries are a different breed.
I suggest taking a read over this page.
http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
In brief stop treating your li-ion battery like its a ni-cad otherwise you will never have good battery life.
http://forum.xda-developers.com/showpost.php?p=23108980&postcount=33
Last run was for 5 and half days with about 3:30 of display time (internet and such), 1:30 of music streaming and like 20 min of voice calling on stock rooted and debloated KJ6.
Yup, I know, for 5 days that's not much of a usage but point is that SGS4G does not use too much juice when idle.

I keep GPS and Wi-fi on all the time, use the phone pretty hard during the day, and still have 60-70% battery left each evening.
You say that you "quit all my apps and free the ram", so I assume that you are using an app killer. My experience is that they are actually detrimental since they aren't needed and many apps just restart in the background, sucking more battery.
Omg people...your using an android....you want everything at your finger tips and wonder why it eats battery
Try all this while on your laptop without plugging it in.....just get an external charger,and a few extra batteries....all in which are very cheap now.......and then we dont have to listen to all this over and over any more.

hey im a noob here so im sorry if this has been asked before but right now i upgraded my phone to ics and the battery life is horrible and im too cheap to get a battery extender so is there anything i can do to improve it or am i just going to have to deal with it?
Get your phone to 100% battery and then just play whatever you like until it completely dies. Then, plug it in to charge and dont touch it until it gets back up to 100%. That is supposed to increase the battery lasting time by 20%. It only works once...so dont do it 5 times hoping for results. This is supposed to be done when you first get the phone, but if its never been you've never done it, its worth the shot.

Let the ROM 'soak' in. It'll get better. You are probably busy messing with it figuring out all the features which is normal and makes the battery seem terrible. But overall it is pretty good.
And the post above is an old wives tale these days. It's funny to read people still recommending it.

Kinda, when you first flash with a factory reset, you don't have a battery stats file. This is another good reason to flash when your battery is 100% charged. When Senior Members here say "soak in", they are saying that the first boot all of the system apk (application packages) are cached to /cache. Doing too much while these apps are being cached screws up the statistics of the battery stats. If I really want good battery life, I totally wipe, and let the phone sit for 10-15 minutes. I leave usb plugged in till it's 100%, then pull the usb and use the phone until it totally dies.
By this time, the day is over and it needs to be charged anyways. I plug it into the charger before bed and let it charge up all the way with nothing running (no wifi, no bt, no background apps running).
After that charge, battery life seems soo much better. ymmv. it would be good to know if that works for you too.
Otherwise, everyone uses their phone differently, and some people install stupid apps that have intensive background services running that eat batteries, then complain about the rom sucking instead of introspecting about how they use their phone.

Just to clarify - battery stats file have nothing to do with battery performance and the battery stat file "is reset every time you unplug from power with a relatively full charge (thus why the battery usage UI data resets at that point)." Google Engineer Dianne Hackborn
ahh ok thanks guys ill do what you guys said and see if it helps
you can also install one of the battery saver apps on the market, like juice defender or similar. They will typically help and some can control how often background services are allowed to collect data.

These arent as helpful as they use to be. I have seen and challenged people to run with and without and the added battery life is either very minimal or actually worse with these apps.
Battery saver apps where created when android was very young and had bad management of the battery power. The way it works now it should lower the power to the radios low enough to save battery but not completely shut off the radios. Shutting them off will actually harm battery life because it takes so much more power to turn them on and off repeatedly then to let them idle.
no i think it was more designed for froyo and gb because if you try those battery savers in froyo or gb you can see it works and battery last long but if you test it in ics or jb (i have test juice defender with jb in the sgs3) and what i can see its that sometimes it lags (not always just when you like two or three apps open which for me in the sgs3 was weird) and data sometimes hangs i mean it doesn't load pages

Download Gemini from the play store and manage the autorun for apps. That's what I do and it saves quite a bit of battery

Ill agree with you on froyo but gingerbread towards the end was much better.
The biggest thing is people dont realize how much power is used to start and stop things. Letting them idle will use battery but not nearly as much if you start and stop many times a day. Now at night if you want to turn off those things then yeah go for it. But if you are a frequent phone checker then starting and stopping them everytime will chew through the battery.
A good example is this, its summertime go outside and look at your electric meter when the ac first turns on. It will spin reeal fast for a minute or so while the system gets everything going then it will slow down. This same thing applies to your phone and its radios. Each time you shut it off it has to go through a process so you dont get corrupted data. And when you turn it on it has to use a lot of battery to make sure things dont get messed up and get to the proper operating form.
So any app that shuts off the radios manually and such will end up costing you battery if you are a power user.
If you can follow the steps exactly as i wrote them, then install the team FAH-Q kernel found in the dev section...

I put FAH-Q kernal on AOKP and it seemed to help a bit. I was using systempanel and it said facebook was sucking cpu at night while the phone was resting... so i took off facebook for the moment to see if any other apps/processes could be causing a drain.
side note:
I spend 15-20 min in the morning going through stuff on my phone. Then I will listen to music in the car on my way to work 35 min. My phone will be at 80% by the time i walk in to work. I check things during the work day once and a while and by 2pm I will be around 40%. leaving work I will have 35-30% .... ok i'll just quit now and say running 12hrs i will have about 15% left. I think I am an average phone user. not sure how much everyone else uses theirs.

Music soaks up a lot of battery as well as display, data, and sync. You can try turning off sync and data when you don't need them. But it sounds like you are doing better. I am still concerned with what else you have running in the background though... however, 12-16 hours isn't bad at all...

What do you mean by totally wipe? do you mean go into recovery to wipe data, cache, and davlik cache? then restore after the battery is fully charged?

Yes, as well as /system/ and at least .android_secure on your microSD
I would recommend against fully discharging your battery as a matter of course. While this might have been useful in the days of NiCads, deep discharges and heat are the Kryptonite of LiIon batteries.
Hi guys and gals (if exist)
I really love my HebMIUI ROM based on Erikmm's latest MIUI V4.
I injected it the latest Team Acid kernel and auto brightness mod and it seem to work flawlessly,
Problem is battery life is just not good enough to serve as a daily driver.
I intend to merge PIMP my ROM mod and DS's A.I when I have time, but I seem to miss something.
I'd be happy to get suggestions.
Here are some XDA version Better Battery Stats raw data snaps : (10x!)
Idk but actually, when I told u my battery was not good and I meant it just could last for a day lol...and I have never used it for more than a day w/o a charge even on GB so i dont think its bad...anw, just try all things u think its good cause its hard to say anything bout tweaks and battery life I think cause...IMO and from what I have been through, scripts and build.prop lines not really help much both performance or battery life...and even OC or UV

I use cMiui 2.8.10.
so I don't know about HebMIUI but i use that rom around 20hr w/o charging.
This rom base on Hefe kernel 0.8(I think)
I tested Hefe 0.8.1 kernel but 0.8 is better than 0.8.1 battery life.
I use cMiui 2.8.10. I think cMiui and Miui is almost same.
I love this rom. I waiting UPDATE. ^^
You can try this and flash rom again.

Hi Dao
I know what you mean..
we both are more than heavy users, not leaving the phone for a minute, so in that way, yes, even on Valhalla I barely made it through the day.
Here I get this issue even if I have no activity and that's what bugs me. Batt is draining no matter what the user does. That's why I shared this technical data presented in the pics.
Thanks MJMJ
I'm not looking for a replacement.
I love the original MIUI, tune and customize it and share it, here on xda, especially for Hebrew speakers, but not only.
Every ROM has his pros and cons. Cmiui is based on cm9 and miui is based on touchwiz. I prefer Miui as it is the original ROM and is generally considered more stable.
I might try Hefe kernel though.
I think problem is related to device awake status...

That your phone is running quite a bit at 100 MHz when I might expect that it be in deep sleep caught my eye. I suspect something is keeping your phone from deep sleep. I can't tell from the BBS you have posted as I'm not sure what you were doing during the time it was collecting stats. I find the BBS from when I'm not touching my phone and it is running on battery overnight perhaps the most valuable.
As far as Hefe 0.8.0 vs. 0.8.1 on battery life, you've completely fooled yourself if you believe you are finding a difference. Go ahead and pull a source diff -- it all is about the interface to sysfs so that external apps can control the UV/OC, not the kernel operation.

I an not a professional. I'm just user of this forum.
I found this about battery life.
about WIFI I advanced setup Keep Wi-Fi during sleep -> Only when pluggged in.
use both of this hefe 0.8 and 0.8.1.
0.8 is wifi off when phone lock.
but 0.8.1 is not.
and battery life is different.
I write just my experience on my larrow professional konwledge.
I'm sorry I can not understand about source code,Interface and UV/OC.
Just experience.
Anyway I love cMiui and Hefe kernel.
Hi
I put WiFi as always on (even on sleep) because I wanted to get whatsapp and work mail in real time. Otherwise I didn't get them in time. Perhaps this is it. I will try it as on only when connected and report.
I would also try it with and without auto brightness mod. Let me know what data do you need.

What follows is my opinion and it is not completely backed up by experimental evidence, so take it as you will.
I don't believe that any ROM or kernel can significantly improve battery life over any other "good" ROM or kernel. I do believe that there are ROMs and kernels out there than can significantly reduce battery life though.
In my opinion, the two biggest factors on battery life (past battery againg) are
How you use your phone
The applications you or the ROM have running
The most insight I have gained on battery life is running BetterBatteryStats on a "full" battery (unplugged) overnight, when I'm not interacting with the phone at all. As soon as you wake up, turn on the phone, go to BBS, and save a full log.
With a good ROM/kernel, I think you should be getting 90-95% "deep sleep" and no more than ~2% per hour (on a typical 1800-2300 mAh "advertised" capacity battery in good condition) drain. If you're not getting that, I'd look carefully at what is keeping your phone awake. If you have questions about interpreting the results, I know the BBS author and has a great thread where you can post your logs and get some feedback.
When the phone is running, it is my opinion that the screen consumes most of the current, assuming you're not a "gamer" or streaming music or other content. Running with dark themes in your apps (as you can), as well as keeping the brightness reasonably low (auto-brightness should help most users here), are good steps to take.
The GP2A light sensor reports 0.75 mA current consumption in Android, so I have a hard time believing that turning on auto-brightness is any worse that running at similar manual brightness levels. If the phone were to be able to run for 18 hours with the screen on (which we know it can't), it would be averaging ~100 mA -- the GP2A would account for less than 1% of that. Of course, that 0.75 mA may not be the correct number. I'm hoping to see if I can do some measurements on the screen drain at various brightness levels, as well as confirm that the GP2A draws minimal current itself. (Unfortunately, the I2C version of the light sensor used in the SGS4G and other phones does not seem to have a publicly available datasheet.)
I think that the way someone uses the phone has a significant impact, even day-over-day. I know that Hefe Kernel v0.8.0 and v0.8.1 have no meaningful differences in how power is managed. The report that one is noticeably different than the other says to me that day-to-day differences in how a phone is used, even when the owner thinks they are using it the same way, are perhaps more than may exepct.
Werd to your grandma!
Good post Jeff!
Good post Jeff.
Sometimes something as simple as playing a game and then switching to something else without the game exiting properly can do it. Once or twice a day on my PC, I'll go to my task manager and notice that IE or Chrome is still running despite my windows being closed. It's stuck in limbo. On a PC, it may suck up a bit of RAM or CPU cycles but if you have 6cores/8gb like me, you don't notice. Something like that on a phone can suck up battery life like a hog though.
Installing 1 badly coded app from the market can do it. Viewing webpages with more of a white background can affect battery life. There is a million things. It's like laptops. They may advertise 6hours battery life. Sure on the dimmest settings with the screen turned down and very few apps running. Stream and HD movie from Netflix and watch how that 6 hours turns into 2. lol.
Thnak you very much good informantion about battery life.
I understand what you say.
About my post.(I use cMiui and Hefe kernel 0.8)
WIFI I advanced setup Keep Wi-Fi during sleep -> Only when pluggged in.
I tested both of this hefe 0.8 and 0.8.1.
0.80 is wifi off when phone lock.
but 0.8.1 is not.
kernel version : 2.6.35.7-Hefe-ics-00044-g151987a and
2.6.35.7-Hefe-ics-00046-g83ec25b
Do I something worng?
I am not complain about your KERNEL or ROM.
I'm very glad you guys about good efect,time and everything for make good ROM and KERNEL.
Thanks again.
I don't think you did anything "wrong" at all!
The control of the WiFi is mainly a ROM thing. Android says "turn off the WiFi" and the kernel does it. I'm puzzled as to why you are seeing a difference. Since v0.8.0 and v0.8.1 are the same as far a WiFi goes, I suspect something else. Perhaps settings not "sticking" between flashes? If it happens again, logcat and dmesg might provide a clue as to why. If you do would you post in either the Hefe Kernel Q&A thread or the Q&A thread for your ROM?
Hi Jeff
Thanks for the detailed posts.
Did what you asked : got 96% after 7 hours of no use, no charge. Deep sleep is 98%.
So I come to conclusion that wifi is sucking up the battery on miui. It has very good reception and always shows full bars for all spots.

Hi
I installed 'Better WiFi' (from the creators of BBS) and set it to open wifi connection only when screen is on and keep it if there is network activity.
Left it at night and dropped from 65% to 35%.
I'm now sure WiFi is over draining when opened.

We all want good battery life, that is a given. With the large batteries and the optimized operating systems versions most of us are running today, we all should have it. But often times we don't, why not? Apps with services causing wake lock issues are often to blame. So, I wanted to start this thread to post all apps we have found to either avoid or with workarounds to prevent bad battery life from ensuing.

I agree, facebook its battery sucker...
Wifi, Scrreen brightness, Auto sync, GPS and games in general seem to be the big culkprits for my battery draining. Even simple things like turning auto rotate off can help a tiny bit for performance and battery life. Limiting your amount of active widgets and screens animations on your fancy launcher can cut down as well on battery and performance. Certain IM apps like facebook chat, skype, and a ton of others will kill your device fast. Google + is known to be a bandwidth hog and batttery killer. I noticed when im browsiing youtube simple things like turning off hd will dramatically help improve battery life because your network is not sucking as much bandwidth.
There is all kinds of stuff to do . It is a constant battle.
Greenify app & use Lean Kernel if possible
Like many have said, apps running in the background are the main culprits of a shirt battery life. Unless you feel those apps are truly essential I recommend uninstalling those apps.

No issues with lux lite here. I got the paid version and the dusk/night features are great
USB Chargers
I don't know if anyone realizes this, but what I have experienced with my phones(from Nexus One - Nexus 4) I have noticed when I charge my phone through a computer the battery seems to go out faster. When I connect it directly to power it lasts much longer.
Has anyone else noticed this"?
