I have Samsung Galaxy S2 with ICS 4.0.3.
From many days, Android OS is causing too much battery drain.
Nothing is running and even then battery is discharging rapidly.
Before that, I used to enjoy 40-48 hours of battery at normal use(only calls & sms).
The screenshot is attatched as a proof...
Please somebody help..
And please forgive me if a thread on this topic already exists, coz I've short time and I m really worried about it.

Download BetterBatteryStats from here (there is a thread), and charge your phone fully, choose kernel wakelocks and when phone is unplugged. When the phone has filly discharged, look at what is causing wakelocks (preventing phone from going into deep sleep). Look up wakelocks on Google and solve problems.

Does that software require the phone to be rooted?

first of all, i dont think that this i anyhow abnormal - since you are using sammy rom, 15% for almost 8 hours gives you 48 hours time between charging.
in settings/battery you should tap the field with uptime, and you will get info about battery discharging - if there are blue bars showing that device is awake, but screen is off, you are probably experiencing wakelocks; then you should either uninstall recently installed app which could wake your phone, or install betterbatterystats and check what is causing wakelocks.

I've installed Betterbatterystats and it shows...
What does it mean?
Sent from my GT-I9100 using xda app-developers app
that means that you had only 1 kernel wakelock, and it didnt last even 1 second.
go to settings, battery, tap uptime and take a screenshot and post it.

yeah, thats the one. compare "awake" and "screen on" blue vertical lines, every time there is line at awake but screen is off, you have a wakelock (event that wakes up device from deepsleep and causes battery drain).
as i can see there are 5-6 short wakelocks which arent too important. you would have best battery life if you choose not to use sammy roms, but its a different story.

there is no easy solutions... but if you want to get deeper into system tweaking, you must read a lot, root your phone and use different kernels to see which one suits your needs best. i could suggest you resurrection remix rom v2.6.1 as one of the most developed ics roms, since jelly bean roms are still in pre-release stage. also a dorimanx kernel, because its most supported. using above combo, i have great deepsleep with almost 0 wakelocks, and about 5 hours of screen time with heavy usage (opera browser almost all the time, and opera is very cpu intensive browser). battery drain while screen is off is almost obsolete.

It's the stock Samsung rom you should do some reading in the original development section if your interested in rooting and flashing.

Hey guys,
I,Ace King 34,made this thread here for you guys to share your SGA's Battery life so that Users who want ROMs that give Good battery life can be helped.
So all you have to do is Capture a screenshot of your SGA's battery life and post it here Alongwith the Name of the Custom ROM that you are using,Scripts that you are using,Kernel that you are using and the CPU configurations that you did.
So first I will start.
I am on Apocalypse Final ROM by itasoulas and I use the Adrenaline Engine 4.2b for CM and I use Firekernel-22072012 And my CPU configuration is Max 806 MHz,Min 245 MHz and governor is Ondemand(many prefer SmartAssV2 though,but I stopped using it)
Attached is the Screenshot of my Battery life On Apocalypse Final ROM.
Your Screenshots alongwith your Personal adjustments(ROM,kernel,scripts,CPU config) will help people seeking Good Battery Backup giving ROMs and also it will lead to ways on how we can achieve good battery backup(with the help of scripts ofcourse )
So start uploading your Screenshots Now.
Note to MOD:-
Hey Mr.Tom please don't close this thread.
I think it will be helpful to users seeking good Battery backup giving ROMS(Atleast then the users(mostly newbies and noobs) won't make new threads like 'Which is good battery life giving ROM' or 'Suggest me some good battery backup giving ROMs')
However at any instance of time,if you feel that this thread is going out of control,then you can close this thread immediately
I thought there was already a thread for this.

Battery threads like these always misleads people since people are trying to brag about their max up-time. It would be better if people included information as setting, rom and daily usage.
On track: My phone usually last around +/-15hours. Data off usually when I don't use it, with below average internet usage, only checking up stuff now and then.
Listen to a lot of music and usually below 100 texts a day. A few calls now and then as well.
I'm using Apocalypse (final) and setCPU(max 844MHz) to enchant it with profiles

What matters the most is screen on time, screen brightness and connection type (2g/3g/wifi/airplane-mode, data on/off). Talk-time matters IF you talk much. Screen and internet on 3g are eating most of your battery.
But in the end everything matters and none of the results are really comparable. So if someone's battery last a little longer then yours, you just don't worry about it. Tomorrow yours might last longer.
Usually 12-14 hours when I am at home (using wifi, using no mobile data, 40% brightness). Usually 6 hours when I am outside (using mobile data, 100% brigthness, sometimes GPS). I have a special pouch for my phone, with pockets for another two batteries. When I am going outside, I have two fully charged batteries with me. 8^) So I can kill green piggies for hours with no fear of no energy. 8^)

Hi, ummm how do i do that? not very technical i'm afraid lol.. it never used to do this drain right down to the point my phone is dead in morning
Download the CPU spy app from the play store. Let your phone run for about a day or so and then check the CPU spy app. It'll show you the various speeds at which your CPU has been running and for how long it stayed at each state (speed)

Hello! I usually get about 2 hours of screen on time on my GS3. After doing some research, i found out that 2 hours is not very good...so I have some questions. Take into account that I have tried to minimalise the us on my GS3 and also watched battery tips and tricks videos and even flashed bestMultitasking fix already.
Is there someway to improve my battery life?
While making this thread, my battery dropped from 36 to 34, using wifi and power saving on...also, my signal is full, so it's not a problem from cellular reception
get checkup of your battery and apart from that also goto settings>battery and see how which activity uses the most battery

It seems that Android OS is killing some of your battery life, this usually only happens when you flash a custom ROM, Id suggest finding out what is killing your battery, download an app called wakelock detector, itll show whats using what
Also, the Greenify app is amazing, it wont let any app you chose to run unless you click it.
You could try turning on your power saving setting, itll slow the phone right down ( thats why i hate touchwiz ) but itll give you an extra 30 minutes of screen on time
Theres always custom Roms and kernels too, Ive got the Illusion Rom which ate up the battery for a day ( every new ROM does this ) and then applied the Googy Max kernel, Im running on 800 mhz with undervolting and still silky smooth
Also, try disabling Google services/ sync and disable Google now, for some reasons they seem to be the issue in most cases

-synchronization

See my current usage now. Attached screenshots.

I'm running on stock rom and stock kernel. I have disabled locations for google apps, all other apps including wheather are able to check for locations. I have sync enabled for gmail, facebook, wheather, whatsapp and exchange. As you can see I was on wifi most of the time and a few hours on 2G/3G/H. You are right with that xposed stuff! Currently running at 380dpi. My screen brighness is on auto with a preset of 50%. My usage behaviour is moderate and includes checking facebook, whatsapp, emails and xda app. I also do much browsing and a few benchmarks and camera shots. I don't play games that much. Personally I think that disabling NFC, GPS and bluetooth saves you a lot of battery. Smart Stay is also disabled because I don't really need that and it's keeping the sensors awake all the time. I should also mention that I have a flip cover with Quick Window enabled. I hope this helps you a little bit. Most of the battery drain is caused by unneccesary wakelocks.I can recommend to check these wakelocks with an app called 'wakelock detector'. As you can see, in my case there is only 1% of wakelocks, where others have 10-20% and this is what's causing the high battery drain. It's all about optimisation! If you have further questions please feel free to ask (but rather in the battery thread cause this might become a bit off topic).
