Hello.
I'm loving absolutely everything about my s3 it's amazing.
But I have one issue, my battery life overnight.
Something is keeping phone awake!
How do I stop this?
Thank you.
Also is there going to be a fix for cell standby? Has any other phone had this cell standby issue and been fixed?

Search for betterbatterystats on xda and use that to find whatever is keeping your phone from deep sleep.

Check wifi sleep policy its by default always on turn it off it will make difference...

But his WLAN is off as you can see. I have the same problem loosing 30% over night although being in Flightmode.
Usual suspects are latitude and the system backup. But as it has been said before get BetterBatteryStats and try to find the battery hog there.
Will do thank you.
Just charging now then will check batt stats tonight.

Download betterbatterystats from xda, just search it and you'll find it.
Android os shows you system held wakelocks, you have an app or service holding a wakelock keeping your phone from deep sleeping.

I wouldnt stress about it that much after getting over a day out of the battery.
Would be different if you had only made it for 4 hours.

With 15% of power used by screen?
That means very little screen on time so over a day isn't that good.
Look at the stats properly before you say not to worry about it.

What apps are you using, and what accounts.
Is e.g. Facebook, Skype or a Microsoft Exchange account configured?
These are known to drain battery and not necessarely under their own name.
'Android OS' means everything the battery stats program (and underlying Kernel Cgroup module) can't put it's finger on. BetterBatteryStats may help you resolve that issue, afaik it's a free APK here in the forum so you don't have to buy it.
Hay guys,
So for the first couple of weeks my battery life was awesome on the s3 and was going an entire day easy with like 40% at night before bed...
However now it is seriously draining fast, I go to work at 8 get home at 5 and I have about 12 percent left with moderately light use...
First thing I thought was maybe an app but in the battery section didn't show anything odd, I got betterbatterystats to see more detailed but don't know what alot of the wake locks are... Here are the screen shots any input/advice is welcomed!!!

WAKELOCKS ask in the better battery stats thread .

Have you changed the Rom? If so you need to download a battery calibrator from the store and reset the stats with it once fully charged.
You might have an app draining your battery, install free "Watchdog" app, and set it to monitor all processes, and it will sound an alarm if an app is misbehaving.
Also install cpuspy and reset the counter and then leave your phone for 30min or so, then check how much time your phone spends in deep sleep.

NOT TRUE.

Thanks got cpuspy and it spend most time in deep sleep... I'm Inking now it's because at work I have bad reception if that's the cause what can I do? If anything lol...

If you dont use 3g or 4g for downloads, switch your phone to gsm, A stronger signal means the phone does not have to work as hard and uses less power.
Also disable account syncing, stops your phone from waking up.

Thats a rogue app causing the high android sys.
+1, I've seen this on 2 handsets.
Using GSam Battery Monitor, then clicking on app usage ->android system -> manage -> clear defaults
The above seems to stop the issue after a reboot. I've not seen it happen again since I did that.
Correct me if I'm wrong, but 9hrs and 47% left doesn't seem like a problem... if you take your phone and leave it on (with screen off) and wait until it dies then charge and turn on you will see that the "system" eats almost all your battery. There is nothing wrong with your phone unless you used it a ton and the system still eats all your battery which If that is the case and it's been 9 hours and had 47% battery then I would think you were doing MUCH better than most, imho.

I've got the same problem. Only yesterday, mine was over 65%! My phones horrible on battery life. Some things definitely up
Sent from my SCH-I535 using Tapatalk 2
When I click manage it won't allow me to clear defaults...
And this began at around the 50% mark and as soon as it starts my battery starts dying way quicker
Do these screen shots help?
Sent from my SGH-I747M using xda app-developers app
any ideas? seems like xda needs to be manualy killed or it ends up using alot of resources in the bacground
I have seen the same on my phone, but it has not happened consistently enough for me to narrow down the possible cause...
Happened to me once so far. Charged my phone to full and went to work. I didn't use my phone for anything other than to check the time. I started noticing that the back of the phone was getting very hot, more so than when charging. I pulled my phone out and the battery was waaay down :
Hasn't happened since (fingers crossed).
Edit: I guess mine wasn't the Android system, but cell standby.

The fix for the cell standby drain is easy, see here: http://techsplurge.com/10665/solution-samsung-galaxy-s3-cell-standby-battery-drain-problem/ As for the android system drain it seems to have resolved itself. I still get alot of kernel wakelocks from bam_dmux_wakelock though
Hi guyz, i recently bought a new samsung galaxy S2.....the problem is that it is giving very poor battery backup.....i switched off wifi, gps, auto-sync etc etc
But still i'm getting very poor backup e.g. I slept at night near 12 with 96% battery but wen i woke in morning at 8, battery remains to 32%....in battery usage it says 61& battery is used by Android OS
What shud i do?

Install betterbatterystat(bbs) and check what is causing wakelock. And we need more info like is data on or wifi on the whole day?

Your phone is not going to deep sleep.install cpu spy and watch the frequences because i think one app is not letting your device to go te deep sleep hope this helps

As it shows 60-70% used by 'Android OS' then it must be some app like thing!!

Just so you know data used quite an amount of battery. Wifi is better than data on term of battery use.

i had something similar not too long ago, and it was also happening first few days when i bought device the most:
http://forum.xda-developers.com/showthread.php?t=1871454
after few days my ICS and my battery made some sweet love i quess cuz i now have decent battery time.
read trough the thread, some say it really could be OS "learns" after some time about your battery (calibrates it)
some say its not that, anyway, i dident do anything and its good now.
cheers

Did you follow the advice of LexterAce in post #2 and install BBS?
If so, why not let it collect information for 5 to 10 hours and then analyze the dump? Almost always the dump can help you to find out what keeps your phone awake.
If not you could also post the dump and maybe someone else can help analyzing it. In the BBS thread are many useful tips and links about how to read and interpret the dump.
Hi, did you resolve the battery problem?
I am in the same situation, can you give me advice guys?
Thank's

I am new to Android and very new to Samsung devices coming from iphone. Last night I was at 100% battery before bed and woke up at 71%. I didn't use the phone once. Is that normal? Should I be turning things off or something? 30% overnight drain seems wrong.

Seems like something is amiss. I left mine on all night lastnight at 33% I THINK and its at 18% right now. 1d 1h 55m 47s on battery with 3h 43m 23s of screen on time right now at 10:29AM
Hmm. I forgot to say I have power saving enabled and the usual battery saving tips too.

That js a very big problem. as you can see i get alot of time on battery. The graph shows that it charged about 10% while I was sleeping (not true). Are you rooted?

I am rooted. I checked battery usage and messaging was at the top? An exchange account is fully set to manual and nothing else.

my device drains less than 2% over the course of 8hrs when sleeping...you have a app causing a wakelock.

No. There's something wrong. Force Close the messaging app and restart it. Wait a few hours and see if its battery usage goes down.
Possible...
The most likely culprit is the "wakelock" issue mentioned above.
Basically it means something... most likely a poorly written app (also most likely a 3rd party non-google app) is preventing the phone from entering its idle/sleep mode, in which it scales back the CPU to minimum, and other bits enter low power states to conserve battery life.
An app that likes to live on the internet or update frequently, or constantly wakes the device to do things, can cause large amounts of drain as well.
It is also possible that signal strength is a cause. Poor/low signal can keep the radio working at higher power levels and that drains battery fast.
Is there any way to check for wakelock applications causing issues? I have removed a few possible applications and force stopped others. I seem to be losing 1-3% battery per hour on idle. Normal now based on everyone's experience?
If it is a signal strength issue I can live with that but the drain still seems steep.
Sorry for the questions. Too new to this to be able to determine if there are issues and everyone is having great battery life.

Several battery apps that can show that type of info, I've used Gsam battery monitor before myself.
gsam battery moniter is what i use on a daily basis. it will let you know what is draining your battery. Link is for the free version. I have the paid.

Gsam battery monitor is pretty amazing. Thank you. I have an application called "Media" that seems to be running at idle. I can disable it but it looks like I would disable the Download application. It includes a process com.android.providers.media and android.process.media.
