I have been running cm10.0.0 on my i747 gs3 for a few months now and never noticed a battery issues until recently. Im all of a sudden getting very poor battery performance. (see attached screenshot). Im not sure what is causing it, but it is draining like crazy. Please does anyone know whats causing this? feel free to ask any questions because i need to get this figured out. Thanks for any and all help!
Looks like you had what I had (a bunch of other people too). I couldn't figure out what the problem was so I exchanged it at the place I bought it from.
It wasn't an app. Better Battery Stats said it was in deep sleep. I charged to 100% and left it idle with everything off, like data and gps, and woke up to 20% left.
If anyone responds to this thread saying "battery not calibrated", "turn so and so off when not in use", "use BBS", "flash a new kernel or ROM", anything cliché, they haven't experienced what we been through yet. *IT'S NOT THAT SIMPLE.*
There's something seriously wrong with AT&T's version of the S3 and no one has taken noticed yet. Noticed all the recent battery threads lately? All say phones are hot and unexplained battery drain. Something is going on and the usual solutions aren't working.

hmmm interesting... this afternoon i made a backup of all my apps and data and booted into recovery. I did a factory re-set and re flashed the same rom as well as gapps. I cleared the cache and dalvik and reloaded everything back up. In the last 6 hours, i have used about 33% battery and over 2 hours of screen time. So it is definitely much much better! Fingers crossed it remains this way!
Just curious, if anyone has seen any random reboots since upgrading to 5.0 or 5.0.1?
I've played around with lollipop for week or so now, and I haven't experienced one single reboot... Unless, I've initiated it myself that is.. How about you?
Not that but bad battery life is affecting my tablet dramatically.
No reboots to speak of for me, and battery life has been about the same if not slightly better.
I got one on 5.0 (kernel panic). Haven't had any yet on 5.0.1.

Weird. My battery's been the best it's ever been.
All location, syncing, wifi etc left on I'll get 7 hours screen time over two days no problem, with no gaming 8 hours. Idle drain is like nothing compared to all previous versions.
Find out what app is draining it or what wakelock is keeping it up. If you haven't already, flash the factory image without keeping data.
5.0.1 is ****ing NICE.
Ny battery's been draining fast as hell ever since updating to Marshmallow, and the top three consumers are: Android System, System (logd), Kernel. They have never bothered me before. They use 60% of my battery consuming. Checking again now, the "logd" changed to "dboxed_process0" and "logd" no longer exists. My battery doesn't even last 2 hours with WiFi when back then it used to last 7 hours woth WiFi. What the hell can I do?
I am seeing a faster battery drain, too. Greenify doesn't even seem to help.
Factory reset is your first thing to do after such a big update, everything else you try is a waste of time until you do this.

I have done so, it still drains fast as hell. It can't be tolerated. What should I do?
Hey guys,
I have been experiencing bad battery life on the latest 19S ROM, i also experienced same on 18S stock.
When i go to battery and view the stats. i always get ANDROID OS which is taking most of the battery life. This is annoying because it seems that it is reducing my usage time.
I read online that it is an app which is causing the OS to remain awake. I have to manually reset the phone maybe 2 to 3 times daily to prevent heavy battery drain.
Can anyone help me to solve this issue?
I deleted the TypeApp email app and had a big difference in battery, it gave me 5x as many wakelocks as anything else
A also have battery drain. Android OS is on top.. Any fix?

Where did you get the 19s rom from? the Letv website here http://bbs.le.com//zt/eui/le_pro1.html only shows 18s as latest?
Ever since upgrading to Android P (OTA) 3 days ago I've noticed the battery life is really poor. On Oreo I used to see only 1-2% drain overnight. Now I go to bed with full charge and wake up with only 60% left. The battery drains a lot faster when I'm using it as well.
I used to be able to get 6-7 hours SOT easily. Now I'm not even sure if I could squeeze 4 hours before the battery is flat.
Is anybody else seeing this? Or is this normal considering Android P just got installed and it needs time to "optimize stuff"? But then again, with Oreo I got awesome battery life from day 1.
Weird, I've gotten better battery life..
Better battery here
Interesting. I'll let it run a few more days and see if there's any improvement. Otherwise I'm going back to Oreo.

Give it some time, once adapative battery figures out your usage and adjusts accordingly, you should see better battery life

Try to factory reset ur device this may help
Thanks guys. I'll wait a few more days. If it doesn't improve will try a factory reset
I'm getting better battery life with Pie
Pixel 1 XL could last a long time. Pixel 2 XL was worse and the worst with Android P unfortunately. I upgraded from Beta, decided to factory reset since there was a bug with Wear OS eating the battery. Got a little better. Got some more little better disabling adaptive battery. I think Doze is still in Android P.
Anyway, it's still not that good. But decent.
I am having the same issue.
when I reboot the phone, the battery seems ok.
But when I start using the phone and open several apps, the battery starts draining quickly.
I installed magisk root, should I do a factory reset and not installing magisk?
I went from a day and 17 hours to 16 hours. This is definiately a piss-poor "improvement to battery life."

I'm not sure how much help adaptive battery is going to help. It's meant to limit background battery usage of infrequently used misbehaving apps. If that's not happening adaptive battery won't do much.

My battery life has been terrible. Today I unplugged at 93%. I've been off the charger for 9 hours with 4 hours screen on time. I'm at 23%. With Oreo that kind of usage would have me at about 40%.
I'd rather not have the hassle of having to do a factory reset but I might not have much choice.
It hasn't got any better since I reported the issue.
I think I'm going to flash Oreo instead of trying a factory reset as I doubt it would solve the problem. Maybe someone else could try and let us know.
I'll report back after flashing Oreo. Very disappointed. I thought this was the first phone I didn't need to tinker with all these stuff on. I was really happy with it until this issue came up.
So a few days ago I flashed Oreo only to have it tell me it couldn't find any of my backups on Google Drive during the initial setup. Of course, the backups were done when I was on Pie.
So I had to upgrade to Pie then factory reset. This time it found my backups.
Yesterday I managed to get 5 hours SOT with about 40% battery left. Life is all good now

looks like i'm going to have to do the same. It doesnt make sense how some people are getting better battery and other worse. Are there some of us running apps not 9.0 compatible? might be worth uninstalling everything and adding them back day by day. it'll take a long time though!

I had a similar experience. Battery life was awful after Pie update. Factory reset and it's back to normal.

same here, slightly better
It appears I jumped the gun. The problem came back yesterday.
The phone loses about 4-5% battery per hour even on standby. I have no idea what's going on; I haven't installed any new apps and usage pattern hasn't changed either.
One very interesting fact I have discovered is that the issue appears to happen only when I'm on Wifi. When I'm mobile data, all is good. So the phone seems to be doing some funky stuff when it's on Wifi lol.
Oh well, I guess I will try to install BBS and see if I could find the culprit.

That is entirely possible. I guess we have apps that have not been written/optimized for Pie? That would explain why some people are not seeing the issue and some unfortunate ones like us are.
I factory-resetted the phone, the issue is still there. I don't have any strange app. It seems that it's just the system that is consuming the battery.
That's very strange I've had the complete opposite, battery life has improved, if reset didn't fix it monitor your apps for unusual battery usage and limit the background activity of battery consuming apps
