The battery used to run flawlessly since I got the phone 8 months ago, I got an average of 12 hrs of battery life. Suddenly a week ago my battery did not last more than 5 hours for some reason, even when I'm at work and it would be on idle for about 8 hours and ends up at 40-30%. I tried killing apps (never did before) and restarted the phone and all. I don't know what's wrong. I really don't want to reset the phone.
Does anyone have a similar issue or a solution to this?

I would probably just reset the phone and don't download any apps for a few days to see if it was a rogue app.
Also is it in a case and getting hot? My friends s3 was in a case and pocket and would get too hot and die fast. Also the hot phone caused a crack in his screen from a 1 foot drop.

Nope the phone does not get hot at all, it stays at the same yet cool idle temperature.

Use wakelock detector and see if you have any apps causing a wakelock.

It's most likely a rogue app.

My GS2 will not sleep. It used to be just fine but two months ago I noticed after leaving my phone alone for two hours thar the batter went from full to 30. It constantly happens. I don't use the phone or even touch it and than when I check it and hour or two later its damn near dead. Is there a reason my phone isn't sleeping when its not I'm use?

There's an app that's eating your battery. Download an app called better battery stats and leave your phone alone. Then start that app and see which things have the most usage

I'm looking for battery stats in the apply market I'm not seeing anything. When I look at my battery useage it says the Android OS is using 66% of my battery!!!!!
Sent from my SAMSUNG-SGH-I777 using xda premium
See that little box that says search at the top? Use that thing.
There's some program not allowing the phone to deep sleep. Look around on how to find what's causing that to happen. (Wakelock)

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

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?

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
I bought the S3 4 days ago, the other night its was down to 15% battery. I plugged it and and surfed the web. about 20 mins in it got super hot and rebooted. today its been freezing up. did I break it? does that much heat hurt the oled screen. thanks
You might want to get it replace, some devices have heat issues.
i don't have such problems in my s3.
plz replace it immediately. because it is very costly device

Anyone else using it? I've used it since OG Droid, and it's always the first app installed on any phone I get. It claims to be giving me 2.01x battery life, and with any other phone I believed it but I'm seeing people post 2 days no charge and I get about 1.25 days with very heavy use, unless I'm at work (12hr shifts 4 days a week). Thoughts? Some people claim it's junk, and I'm not so sure with a battery as big as ours we need it, or if there is a better alternative? I mean we already have a Battery Saving Mode...

I'm using it,I think if you configure it with the right settings it can save you a good amount of battery.

I personally don't think it's needed on this phone because how long the battery already lasts and I like my smartphone to stay smart. But on my lg spectrum I used deep sleep battery saver, it was pretty good.
Also on a side note time up isn't as important as screen time. I could get days if I didn't use the phone, but if you are always on it 12 hours is pretty good
Sent from my SCH-I605 (AKA NOTE 2)
I think battery saving apps are obsolete now because phone's are becoming more battery efficient and batteries are becoming larger (Mah). I don't see any need for a battery saving app anymore especially with this phone. Just uninstall it and some more RAM

I had some issues with my battery when I got it. Turns out the stock clock/weather thing on the lock screen couldn't get a lock on my position (just kept saying "current location"), and would run GPS for 10 seconds whenever I unlocked my phone. After fiddling with GPS and the weather settings themselves for awhile to no avail, I said F it and just let it happen. Eventually it got a lock and since then battery life has been fine.
Battery is fine for me

Buy a new phone.
I started this morning around 75% and got to 8% in about 8 hours of heavy usage. I must have sent a few hundred texts today along with a bunch of snapchats, took a bunch of pictures, web browsing, some Navigation use, an hour or so of Skyping, and a whole bunch of other stuff. Battery saver was on, but I had data running all day, Wifi and LTE per the situation. It actually said that Messaging was the main battery hog at 32%.
What I've taken from it is that if you're going to be using the phone heavily, it doesn't hurt to have a charger.
Where do you guys see how much screen time is used? I don't see it with sense
Sent from my HTC One using Tapatalk 2
Weird, my battery just went from 8% to 32% from being on the charger for a few minutes.
I guess it's not calibrated very accurately yet.
