I get a battery drain problem. when the screen is off, the battery drain is normal, but when i'm using my phone, no matter what I do, it drain 1% per 2 min(I think). And I'm not sure, but I think I have this problem on any Leak or Stock i'm on... ! what do I do?

Go into system settings > Battery and check what is using most battery.
If it's screen there's not much to do other than leave auto brightness on.
The phone does use a lot of juice when it's on though, undervolting and underclocking might help a bit...
download cpu spy and betterbattrrystats
1 double check your phone is going into deep sleep when u switch of screen
2 use betterbatterystats to find out what's using all ur juice ( disable all the things u can ie sync mobile data etc)
3 have u overlooked or undervolted
4 what is your max cpu freq set at.
5 once you've found rogue app remember to uninstall betterybatterystats otherwise it will eat your battery ( learnt from experience )
hope this helps

1. how do i check that?

3. nope.
4. how do i check that???
5. ok!
1 cpu spy tells who how long in each freq sTate your phone has been
make sure "deep sleep" got the most time
2 hmm dunno then
try setting screen brightness down.
don't worry about 3 4 5
sounds like some app us constantly updating what you got running .

the deep sleep has the most of the time. so as the 144MHz, about 1 hour, and the 200MHz, 1:24 hours.
how can I check what app uses the most of the 1400MHz and the 200Mhz???
It could be media scanner. Sometimes it get's stuck and keeps on running. You can download rescan media from playstore and disable it.

Ouch! That's a bit lot. I just flashed DL1 2 days ago and all is much better than in previous (ROM 4.0.4 BLG8). Since morning(6:30AM) down to 72% now(2:50PM).

Not really. I'm a newbie myself so sorry mate.
You could post your better battery stats on its thread. People there usually analyze it for you.
But basically your looking for apps with high time and /or count.
Each count represents that app going out of deep sleep for a microsecond or less. So an app with a high count will be constantly waking up your phone even if it's total time is only a few seconds.

Try to use watchdow to see wichs apps/process/system process are using most of your cpu, ma xcpu freq (1400mhz) shouldn't be that high so maybe a rogue app is draining your battery
If you want to see the wakelocks i recomend using GSam battery monitor, in the app sucker you can see wich apps are waking your device an how many times, but you have to try out after a period of time
The other problem could be some corrupted media files that make your mediaserver drain a lot of battery, if so, check the .nomedia files in your sd, look for image not loading in the gallery, use an mp3 checker app to se if some of your music files are corrupted (search through xda, someano posted an utility to do this) and try to re-encode your mp3, in my case, this solved my issue

it could be a whole bunch of things, people won't be able to help if you don't post any info of your device rom/kernel, wifi on? gps on? screen brightness? all that needs to be taken into consideration.
The most common problems for battery drain are media scanner as mentioned earlier, Google maps, wifi is a big drainer even if you are IDLE for some reason wifi keeps on receiving something (i'm guessing it is the "keep alive" packet) but havent dug into it, also found that "Samsung push Service" was sucking juice so I froze the bugger, the last thing I found on my S3 (runing Wanam's leaked JB DLH4) was "DRM Protected content" for some reason it kept coming up so I froze the sucker with Titanium backup and i'm doing around 20 to 21 hours average.
I've used Better Battery Stats, Battery Drain Analyzer and Android's own battery analyzer to keep track of my usage.
I hope anything of this helps you and good luck on your findings.

i'VE BEEN RUNNING CM7 for a month (about)
I update to the latest version and right now im on the KANGED version thats not OFFICIAL release but it is made by the dev.
Anyways...
Every day i wake up in the morning, from 100% my battery goes to about 90- 85% from using it then i go to school, phone in my pocket for about 7-8 hours.
It usually goes to 70% or 75% when i check soon as school is over.... but today.. it was at 32%!!?
My battery has been draining FAST this past week. IDK what's causing it, but i think its a app, but watchdog lite doesn't show anything at all.
Any tips at all guys?
- PLEASE DO NOT REPLY TELLING ME TO PUT IT ON AIRPLANE MODE WHILE IN MY POCKET- I GET TEXTS FROM MY BROTHER/MOM TELLING ME IF I HAVE TO WALK OR IF THEIR GOING TO PICK ME UP AND OTHER IMPORTANT INFO LIKE THAT-
Please help me out here.
I love CM7, and it's NEVER been this bad, but if it is because of CM7 then i have no choice but to go back to 2.2.1
EXTRA INFO:
I don't have a data plan so... my phone can't communicate with other servers and crap.
I keep wifi off, bluetooth off GPS off.
Maybe i'll have auto brightness on but thats it.
Check what profile are you using on setcpu? Also you might wanna check the signal while in you school.

try recalibrating the batter by using either root explorer or the terminal to delete /data/system/battstats.bin as sometimes CWM on cm7 for galaxy s doesn't delete it.
i have the same issues and tried everything..i dnt even have data plan to use internet and i keep my 2g on and my battery still drains like pipes in the sewers

try not using the battery claibrator app, and removing it from your phone and manually deleting the batterystats.bin file from /data/system and see if that helps your phone at all.
I also suggest getting CPUSpy from the market, and track what states your phone is in and for how long it is in certain states. if it's not going into the sleep state, then something is keeping the cpu active (possibly a governor setting).

That aint normal my friend, you should jump into another modem, regardless of what you're on. Maybe that helps and by all means, what kernel are you on?

The stock one should be battery efficient but I honestly haven't really tried it out. Give r12 or r25 a shot from here. They've been great in every aspect to me. Just make sure you're not on kang 7.1 when flashing, it doesn't support that.
As for modems I'd suggest either KB5 or KB1. If you're on either one switch to the other, may help.
don't run phone on "performance" -- it's silly to run the cpu at top speed when the phone is just sitting doing nothing. Run it at "on demand" or "conservative" especially if it is OCed. Also set screen timeout at a minute or less. If you got the phone used, it's possible the battery is old. If you reboot it a lot and install roms and stuff you'll run the battery down fast.
Well..
Yesterday I did a cleaning of apps i never use and some i installed recently.
I guess that did the trick? I have no more problems came back from school and my battery's at 76%
@Abu, thanks for the tips. i don't want to get a different kernel and modem.. im on kanged 7.1 lol.
@Nazcalito
Fearing it was that i uninstalled SetCPU.
Should i re-get it and make it OnDemand?

don't use setcpu if you don't have to. the built int scaler for the kernel is actually much better than letting setcpu run in the background polling the cpu and system for changes.
if you're running a custom kernel, get voltage control, and with it you can UV, OC, under clock, and change scheduler.
And in Settings -> CM Settings -> Performance -> CPU Settings, you can control min frequency, max frequency, and governors.

The only time i use internet is at home with WIFI
I have this S2 for about a month now and up 'til about 2 days ago I was getting quite frustrated with the battery life. From 8am to about noon I'd be down to sometimes 50% and by 3pm I'd be getting ready to put it on the charger at about 20-30%.
So a couple days ago I decided to uninstall Advanced Task Killer Pro (with advice from some members on XDA) and installed Watchdog and blacklisted at 1% threshold a whole bunch of stuff. ie. Wifi Sharing, Social Hubs, etc.
Now it's almost 4pm, same usage as before and I'm at 73%! Compared to before it's a major breakthrough. This is battery life that is expected. So maybe some of you guys should try the same and see how it works for you. Cheers.
what are all the apps you blacklisted?

Here's the best part... NO ROOT!
I just downloaded Watchdog pro, you did not make it did you , I don't want to root as i paid a lot for my simfree S2 and i have only had it a couple of days.
I see you are using "Battery Monitor Widget Pro" , I have been using it for months with a few android phones, I wish Samsung had realtime mah/current usage like HTC.
I have my S2 on charge at the moment with an 650mah Sony Ericsson charger, and "Battery Monitor Widget Pro" is saying it`s charging my S2 at 989mah
Check out my post history and you'll see where I discovered Watchdog. I have nothing to do with that app.
5:30pm and I'm at 61%. This is outrageous. Normally the battery would be completely dead at this time and already on the charger. Screens attached.

I set the threshold at 1%.
Mine is very odd. Overnight, everything on (no special settings), I typically lose 10-15%. Nothing changed. During the day, I lose 40% with maybe 10 minutes of use. Display is always listed as high, but with 10 minutes of use, that seems really weird.
This whole battery thing is also temprature related. Yesterday was kinda warm here. Had to charge my phone twice. While normaly on a lot of use I can get 12+15hours.

It's called 'Watchdog Task Manager Lite' or 'Watchdog Task Manager Pro'
The Pro version has the blacklist feature, the lite version works more like a task manager, monitoring CPU and killing apps when they reach a certain threshold use of your CPU. In the UK the Pro version costs £2.14 (exVAT).
I have a problem with my battery I have my new sgs 2 and I rooted and did a new rom and all but my battery is draining really fast under moderate use! 3 hours of moderate use and I lose about 30% battery! What can be the problem? I calibrated and did speedmod kerenel, still heavy drain... in sleep mode I guess it can last like 2 days but I want to use my phone constantly without loosing so much battery
Sent from my GT-I9100 using XDA App
As far as I can tell based on this information, you have no drain. It's normal that the screen consumes power. If you standby time is 2 days, then you have no battery drain.
Lower your screen brightness and avoid using white colours. And no there is nothing else you can do.
But I see slot of people who get 10 hours of use on moderate and even heavy use,.. maybe it's my rom? I use rarity rom with speedmod kernel, maybe I should use checkrom?

No one gets 10 hours with screen on. Thats what you are talking about right? You get 3-4 hours max.
So 30% in 3 hours is normal and not bad.

Whichever ROM makes you not use your phone. Probably best to choose the worst looking one you can find, so you're less likely to use it.
You still don´t understand it. The screen uses power. No matter what rom/kernel you use.

Sent from my GT-I9100 using XDA App
No there isnt, at least not afaik.
Get urself Android Assistant, switch to Tools and check out Battery Use. If u click on the "Other" button u'll see exactly what drains the most power. I'm almost certain it'll look like this:
Display
Android System
Android OS
Display can only be reduced by brightness, auto-rotate screen and Auto adjust screen power (See Display settings)
Android System includes many packages. (Look up the details in the Assistant to see which ones u can kill for now)
Android OS is mostly ur CPU clock. U can get urself SetCPU (root required) to lower ur clock frequency (mines set to min 200/max 800; on demand). Everyting runs smooth and I dont see any difference besides 2-4 more hours of battery
Dont set it too low or it wont start up anymore!
The Assistant quick boost widget is also pretty useful. Just click on it and it'll kill all unused apps increasing ur TTL, even if its only a lil bit.
Hope this helps!

After experiencing extremely bad battery life and searching everywhere around the web for answers i have found a solution for wakelock problems that solved all my battery woes.
Thanks goes to the people that originally found these fixes.
This step stops the AudioOut_1 partial wakelock bug from keeping device in awake mode:
0.go to settings > sound and turn off touch sounds and screen lock sounds
These steps stop the kernel wakelock 100% problem:
1.turn on aeroplane mode
2.turn off device
3.take out battery for 10 seconds
4.turn on device
5.wait for everything to load
6.turn off aeroplane mode

for facebook wake ups the only thing I found is freezing it with titanium and make sure your disconnected from it every time you quit this app

for the rest I don't think we can make something unless sammy release the source and finally an official ICS !

These fixes will help your battery only if you have wakelock problems,they don't do anything otherwise.
I also resent black magic recipes. Some time ago I read that many common battery saving apps and tips don't help the battery,sometimes even causing more battery drain.It was an independent research where they regularly tested the battery itself with ampermeters.

You neet to find out which wakelock are draining your battery when the screen is off before you trying out some "Black Magic Recipes".For instance ,if you installed some instant message app which keeps pulling something from the server and prevent your phone from going to deep sleep, disabling sound will not help you get better battery life.

These steps stop the kernel wakelock 100% problem:
1.turn on aeroplane mode
2.turn off device
3.take out battery for 10 seconds
4.turn on device
5.wait for everything to load

Or do I wipe after I perform the update to ICS? Along with a factory reset? Someone please help, thanks..

I had issues with reboots and poor battery life after upgrade. I went back to gingerbread and done factory reset. Once booted I immediately went to kies and upgraded to uk ics. I have no issues now with reboots or battery. Very happy now and speed is great. Remember to factory reset in gingerbread and not ics. Just reinstall apps from the play store after.

After experiencing extremely bad battery life and searching everywhere around the web for answers i have found a solution for wakelock problems that solved all my battery woes.
Thanks goes to the people that originally found these fixes.

Thanks!! It worked for me when my Galaxy Note was running ICS and now again when I have downgraded to GB.
CPU Spy showed 200 Hz to be the lowest state touched and there was no Deep Sleep. After these steps, it goes to Deep Sleep when not used.
Ok people I could use some help. I think I am getting some average battery times but the score card would definitely say 'could do better'.
So what I want to know is what screen shots from BetterBatteryStats/Phone/other would I need to upload here to help someone with far more technical nous than me identify what is causing the drains and how to stop them?
To start here is my battery screen shot for today. This is with approx. 3.20hours of screen on time.
The screen is a real battery-hog due to it's size. You may want to lower brightness, that helps a lot.
For starters, please attach Kernel Wakelocks and Partial wakelocks from BetterBatteryStats, that shall show if something drains your precious juice.

Excellent. I'll start with that. Would have done it this minute but I just plugged my phone in....Doh! Will upload this this afternoon.

OK here we go....I guessed from looking around the forums this is the best way to deliver the information? If not let me know and I'll change it.
Analyse away
Not sure whether this is relevant but I have Tasker turning WiFi on and off in two locations.
Alright, let's see: Your phone's screen was on for an hour, but the phone was awake for two. That means we found a wakelock. Unfortunately I have no idea what "deleted_wake_locks" stands for. Maybe someone else knows more about this. Besides that wake lock, you seem to spend quite some time in an area with bad or no signal at all. That will drain your battery pretty quickly too as the phone is constantly searching for a better signal. You might want to turn of phone data in that area to prevent to phone from trying to get a better signal all the time. Finally, you should consider getting rid of the Facebook app. I've read that it isn't exactly gentle when it comes to saving battery.
Rationale: In the API available to android drivers it is advised to call wake_lock_destroy before freeing the memory of the wakelock struct that you created. This is probably done on shutdown OR perhaps if for some reason a driver is unloaded from the kernel. Whenever it does this it ads the wakelock stats to the deleted_wake_locks.
Know actions: AlarmManager itself is not generating partial wakelocks but the applications (intents) that were set to be called when an alarm goes off do. Alarms can be listed through the menu "Actions -Alarms".
Known conditions of occurence: In relation to Wifi and depending on the sleep policy wakelocks seem to be collected when screen goes off and Wifi is turned off

That doesn't help battery life, that just fixes an error in battery stats reporting.
That cell standby problem was NOT draining excess battery it was just being reported incorrectly by the android battery stats.

easy. use speedmod kernel
i am use ninphetamin3 1.20 with criskeloron v5.1 and my battery life is good
Surely it's not just the kernel though? I'm using Siyah as I thought that was supposed to be good? Will changing it help? Surely it's not that causing the wakelocks?
Any other suggestions or comments on the stats I posted ?

Maybe post a batterystats dump in the betterbattery stats forum.. it would be cool if some guy who could really read onto batterystats very well to start a betterbattery stats thread just for us gs3 owners.. would help everyone..cos gs3 is a popular device and it would be easier to post them here for quick answers

Mmmmm maybe you sometimes find that responses get lost in those things.
Anyone else able to help here?
Your battery goes down steep all the time, but according to your screenshot of the battery stats there are 2 critical points, the latter not ending.
Please next time also include a screenshot of the menu appearing after tapping on the graph (which includes screen-on, wifi and signal quality)
According to BBS some of the issues are related to:
No or Unknown Signal (): 1 h 26 m 54 s (5214 s) Ratio: 20.5%
Poor Signal (): 1 h 4 m 45 s (3885 s) Ratio: 15.3%

No or poor signal causes heavy battery drain since it keeps searching for the network until the connection is re-established.
Are you on 3G connection? If so, Facebook is a known battery drain.
Try using 2G whenever you're not needing the speed and see if that improves your battery life. (Only to test for now)
Alternatively disable Sync (all of Sync, not only Google or Facebook) and check if that improves the life.
You are on an old ROM version, try upgrading to a BLFB-based firmware or a CM9/AOSP based one. Both have great battery life improvements over the old ALEx Roms.

Can I just upgrade the Rom from the ALEx one I currently use or will I have to go back to stock in order to do it?
