Hi there,
just in advance: Yes, I have read quite a bunch of battery drain threads, but non of them seemed to help me.
Compared to GB, my SGS2 doesn't even seem to last more than a day in terms of battery life.
Now I wonder - is it just me playing around with (otherwise awesome) CM9 and battery life is actually normal or is there some kind of battery drain going on?
Running CM9 14-04, stock kernel, LPS baseband.
Attached please find BBS stats and other battery stats screenshots.
Help very much appreciated

Awake over 2 hours, 1 hr 43 min screen on, down to 62%. That's on track for 5.5 hours awake time, and about 4.5 hours screen on time. Looks pretty normal.
You MIGHT be able to squeeze a bit more juice out by playing with your sync and display settings, but that otherwise doesn't look that bad.

Sync is pretty much off completely and display brightness was on 'auto'...
the graph looks pretty good without gsf and alarm manager wakelocks
Have you tried to re-calibrate your phone? I once messed around with my battery and i lost 70% battery overnight when it was on 100% because i was unplpugging, plugging my phone in randomly.
How do I do that?
Just bought a 2000mA battery and it seems I still got the same 'issue'...

Download battery calibration app from play store, put phone on charge, wait untill will be 100% charged, open battery calibration app, click calibrate, unplug you phone. Done.

Did you try to wipe your battery stats? Also, I noticed that playing around flashing the Roms, requires 2-3 full charging cycles before the battery was "stable" again
I've also read the following but didn't try it (I imagine it does the same than wiping the battery stats in the recovery, but you never know, you can try it):
Delete batterystats.bin in data/system, after full charging (with Rootexplorer or another app)
Then, use it until to 90%, and full charging.
Good luck!
When is it a good idea to wipe battery stats? When it's empty or at full charge?

The CM9 has some battery drain problems because is still developing maybe try wiyth another rom and see if the problem remains

Stats seem fine to me. Your phone shouldn't drain much when idle, but once that big screen is lit up the power drains much faster. The SGS2 stock battery is not huge to begin with either. Your 2000mah will be better though, especially after using it for a few cycles. You can also try flashing a different stock kernel or custom kernel (Siyah, etc).

Thanks guys!
So charged my 2000mA battery up to 100% now and wiped the battery stats. Hope this helps.
I really wanted to stick to CM9, because I don't wanna do a factory reset every couple of days when flashing other ROMs, because I'm tired of setting up all my stuff over and over again...
Are the other ROMs really that much better? Thought that CM9 would be best, because most popular...
Or could it be the baseband/modem too?
I am on LPS right now... I've searched the forums forever, but can't seem to find an answer for:
What is the best baseband/modem for battery life?

Hey guys,
I have been running unnamed rom lately, but on any other rom including stock. My battery lasts for like 8 hours with little use and 4 hours with moderate use. When I see what is draining my battery it looks normal as the display uses the most, but I only have it at 30% brightness most of the time I have insurance should I see if I can get a new battery? Or any other tips?
Can you post a pic of your battery usage?
Have you tried to calibrate the battery yet?

Many things could cause battery drainage, such as oc-ing. You could find the original Samsung battery on eBay for a cheap price. Before buying one, try doing the following:
Clear OC/UV settings (i.e. put to defaults)
Download Battery Calibration by NeMa (on the Play Market)
Charge your phone and wait until it reaches 100%*
Tap on "Battery Calibration" and done
Once calibrated, use your phone as you normally would until the battery dies. Only when it dies you can charge it. You can charge as you please from then on.
Note: If it does not reach up to 100%, go to CWM and clear battery stats.

The usual applies - look in battery statistics, use BetterBatteryStats to hunt wakelocks.

THIS DOES NOTHING ON ANY SAMSUNG GALAXY S DEVICE!
never tried the battery calibration?... does it actually work or no?
have you installed any new apps recently? those apps that use a lot of apps in the background are a pest to your battery life as they usually won't show up in the battery monitor. try disabling your data when not in use and see if that helps. if the current rom you are on does not have a toggle bar with data use the "data enabler widget" by Farproc.
I've been using my s3 for the past one week and my device shows 99% assoon as i remove my charger! i've tried changing the rom, erased my Battery stats, recalibated my battery using playstore apps. even though it shows 99%. please help! by battery life is worst!
All GS3's are like this only. The battery actually never charges to 100. Its purely cosmetic.
Please tell me you've actually tried searching for this before posting since there are literally dozens of threads and discussions revolving around it.
Physically it's very simple. If a battery is 100% full, it's as full as it can get. This is not true for everything but for most consumer-related stuff. (Airplane turbines, reactors and other industry-machines see it as a maximum value for long-time usage but can go quite a bit above)
If you unplug it, your phone starts draining battery since -surprise,surprise- it needs power. So the battery cannot stay at 100% if a (however tiny) part has been removed.
Phones that remain at 100% after unplugging for some time are lying to you to make them look better. And you don't want a manufacturer lying to you, do you?

Better check of you have rogue apps in the background or your screen brightness, my batterylife is quite good (about 2 days with medium/heavy) use. Running stock firmware.

That's perfectly ok. Relax Been discussed here already...
PS absolutely no need to calibrate the battery
This happens to me as well but don't fret over it.... Calibrations should be done regularly but not overly or it'll stress your battery more than necessary.
You do not calibrate your battery regular the year is 2012 not 1995 .
Battery auto calibrates itself use it ignore it .

I'm amazed how people can get nearly 2 days with medium usage. Do you have any apps installed? How many hours screen do you get?
It seems it's pot luck with battery life..
I am getting some strange battery behaviour.
My device will turn itself fully off when sleeping about once a day. The power use graph often has strange jumps in it as well.
I've tried resetting battery stats but it's not made a difference.
Any ideas what could be causing it or how to fix it?
I've been having the same issue for the past few days. I've also been having a good amount of crashes. I am thinking about starting completely over: Odin back to 3.2, reinstalling CWM, and then trying the nightlies again. If that doesn't make it more stable, I may try Task 14 (HC).

Well first, I would not recommend Juice Defender. I have heard that it causes the batter to drain more.
Secondly, the stats are only for not even 3 hrs. If you want a proper reading of what is draining battery it needs to be longer, if possible.
EDIT: What rom/kernel are you running? And did you do a full wipe when you flashed them?

I need an app that turns the wi-fi off when i'm not using it as I find wi-fi being creates a big battery drain. JuiceDefender has served me well for that purpose for years. Any other apps you can recommend for automatically turning off the connections?

I was running CyanogenMod 9 Nightlies Galaxy Tab 10.1 WIFI, then after a week switched to [ICS]Ganbarou GT-P7500/7501/7510/7511 CM9, and I am now as of yesterday on [JB][AOSP][ALPHA] Android 4.1.1 - Jelly Bean - [GT-P7510], full wipe as usual for them all, bar JellyBean where I had to return to stock first.
I've had the same power problem on them all, but i've noticed i've managed a 10hr stretch on JellyBean, so stats are attached.
Problem fixed.
I installed the Jelly Bean alpha, but it was still happening, so I drained the battery completely, then charged it fully, and that fixed the problem.
I was really suffering from massive battery drain....see here - http://forum.xda-developers.com/showthread.php?t=1933012

I have completed many many cycles of battery from charging to full....and discharge to 0.....Also i used the battery callibration app SEVERAL times!!!!........But nothing seems to work...
Can somebody help...Please

Did you try to delete battery stats? Or use an app to improve battery life?
I have the same issue too when booting into recovery. I don't worry about it. I suggest the same as Ramjet in your other thread.

I had this issue with my old battery and old charger,
Now I dont use my phone while charging , I charge other batteries with the wall charger while using other ones and everything is fine now.... battery % seems to be same in both android and recovery.
I have that same issue too. Lol maybe the recovery can't read the battery correctly. It'll show up higher in recovery and then when I reboot, it will read the same way like in recovery. Tried numerous batteries with the same result. Although I havnt tried battery calibrating. Ill give that a shot.
Is there any solution ??
Try klect's solution and go into recovery, wipe battery stats. Then let your battery drain and die. Then charge your battery back to 100% with no interuptions like pulling your phone off the charger too soon. When you wipe your batt stats you are getting ready to recaliberate your battery. After you let it charge to 100 percent. Let it drain to 0 a couple times to recondition your battery.
You do know that the evo 3D gives around 3 hrs of screen time dont you? even on stock rom on normal usage. If you have the wifi on all the times you'll get around 2:30 maybe 3 on a full charge.
Your battery certainly is draining faster than usual but have you tried keeping it idle and seeing what kind of drain you get? From that screenshot in the other thread it seems like your phone is getting some heavy wifi browsing or something (and do check if facebook or email apps are the culprit. Having push email on drains a lot)
And the recovery/rom reading wrong stats happens all the time. just recalibrate your battery like these good folks here have already suggested
Yes i keep wifi on all the time...
But once i kept my locked for abot 3 hours after full charge...when i unlocked it showed 99%...i was happy and i didn't do anything just surfing my screens it dropped very very fast to some 70 % !!!!
Also please hit our thank you buttons please. Even if you didn't get the exact answers you wanted. It's appreciated for helping one another.
you really should check your apps battery usage using one of the apps ramjet73 told you about
ramjet73 said:
There are a bunch of tips here.
Usually that kind of drain is caused by an app. Try running a stock ROM for a day or two and see if the issues go away. Or use one of the battery monitoring apps (BetterBatteryStats, SystemPanel Standard, Battery Monitor Widget) to determine which app is causing your drain.
It may take some work on your part to isolate the problem since there is no global solution to battery problems.

top culprits are mostly facebook,email exchange,google maps and pretty much anything that syncs alot
Also try using you phone on min brightness auto brightness is also a battery killer

Hey!
I´m running Omega on my S3 and I love it but since I first installed it I´ve been having problems with the battery, it seem like it is just getting worse and worse.
I think I am getting 1/3 of what I got with the stock ROM.
Any ideas?
Before i have the omega rom and i have the same problem
i have install the Android Evolution HD and it's very better !!
Problem , Android Evolution HD is a simply rom like the original rom, but you have mods ^^
I have exactly samr situation as above poster, Omega and Android Revolution HD.
But I figure, at least to me, it is possible due to 2G/3G network connection
Sent from my GT-I9300 using xda premium
I've been using Omega for quite some time now and I've tried many settings to maximize battery life like shutting off radio signals, disabling fast dormancy, even using a darker wallpaper to save that extra bit of juice...but i must say this rom just finds a way of sucking all the battery out some way or the other.
I might try Android Revolution now hmm
Thanks guys!
First I thought it was something wrong on the hardware side but now I am sure it´s the ROM.
It´s a shame because I really like some of the features and aside from eating battery fast it also freezes, stops and turns into a brick for a minute or two sometimes. My beloved SGS III is no longer very reliable but I thought those were the consequences of starting to play with the ROM, this is my first time I do something to my Android phone. I´ve been jailbreaking and trying different things on iPhones but never on Android.
Seems like the only solution is to try a different ROM.

Yes, everytime after flashing a new ROM, you got to do this and give it a few days for the newly flashed ROM to settle down to be able to measure battery life better.

If I understand correctly, wipe battery stats only remove battery statistics, it does not improve battery life. See:
