[Q] why is 'phone' eating my battery?

The phone app is eating more battery than my screen. At night, it eats away 25% of my battery. Anyone else have this problem? Stock, no root.

Same problem here! I don't know why the phone app is draining my battery in stand-by mode.

I find using the phone drains the battery. I try my best not to pick it up, but I have no control. Can anyone help please?

Used to, but not anymore

i had the same issue, just disable auto sync (and google now if you dont use it, because it keeps searching for info when the screen is off).

Yeh thats usually what happens when you use the phone, it will use the battery... I have some good news thou, you can actually charge it back up with the included charger and use it again :good:

All kidding aside, ill try the sync and Google now tip. Will report back.

I also have the same problem....
I have installed Cpy Spy and it shows it does not go too deep sleep......

[Q] Battery life? WTF? 10% an hour doing NOTHING ?

I lose 10% an hour (sometimes more) doing absolutely nothing with my phone. I check battery stats and like 98% is screen.
Question: how can that be possible if the screen isn't even on ?
I have tried everything. I'm running CM10 stable (which is supposed to be good for battery life)
10% an hour? This is a joke right? I have like no apps running. I even tried using apps that put the phone into DEEPSLEEP as soon as the phone/screen shuts off -- meaning every app is closed.
Nothing.
Any ideas? please help i love this phone but im going through 2 batteries a day and im not even using the phone that much.

Battery drain by unknown usage

Hello guys,
I'm having issues with my battery when using the same ROM more than 2 days. I explain myself, my problem is after a complete battery cycle (from 100% to 1% then charging...) my battery drains drasticaly (look at the screenchot). I did a reboot and it dropped from 95% to 30%. It happens to me on these ROMs (Rootbox, Carbon, SlimBean, Illusion...) I use KT kernel and sometimes BMS but same result. So i dunno if the problem comes from the ROMs or the kernels... I will look further into better battery stats to see which app is causing this.
Thanks for helping and sharing your stats !

I would try a full cycle or two with the stock kernel.
Or if you want to go one step further. Backup everything, nandroid and Odin back to stock and try a full cycle on that.

You could install Wakelock detector, [https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en] maybe its some crazy thing that eating battery.
Try using intellidemand as your governor on kt kernel, i was having problems like you until I used that governor.
Hope this gets resolved

Thanks man for your help but I think my problem got solved by doing 2x full battery cycle with stock kernel (I cross my fingers ). If the drain issue still comes after that I'll try using intellidemand as my governor!

After two or three charge cycles if your battery problem persists, it's most likely an app draining your battery. Or worse yet, your battery is shot.

Wow this morning I had a full draining after charging my battery to100%. About an hour to drop to 0%. I used battery calibration since yesterday so this could be one of the battery stability issues. Any idea?
Sent from my SGH-I747 using xda premium

Now my phone cannot perform a clean deep sleep without having a full battery draining... Battery calibration is definitely the problem. Any suggestions to solve this?

Take ur battery on smooth surface and rotate it does it rotate more that1080° then ur battery is problem.after reading can i suggest u something try some stock(factory) roms like from ur company provider and check and let me tell u one thing calibration works only when ur fones battery is old and it works like little bit not a great advantage of it and no battery savers actually save battery infact they are the ones to eat them and use task manager from ur system to check which app is running in background
Press thanks if i helped u

[Q] [Battery Drain] Android OS sucking a lot of battery

Hello,
From the last 2-3 days my phone's battery life reduced by 4-5 hours. Upon checking I found that Android OS is taking a lot of battery (Image attached). I have just a couple of sync settings on. Its also keeps the CPU awake. Please suggest any way to stop this.
Thanks

When did this happen? What did you do anyway that made your Android OS blow up the roof?

Thanks for the reply, I ain't on CM11. Just the stock rom with gravity Box Mods.

44% is too much. Which FW you are using? And are you rooted?
If yes set lower CPU when screen off, that saves battery a lot, n did you turn stamina mod on?
Look at mine

Thanks for the reply. I am using Stock 4.1.2 Build 15.1.C.2.8 (Fully Rooted with busy Box). How to set lower CPU? Also, I don't use Stamina mode as I get a lot of Emails and I need push notification to work for that. Any other solution that you can suggest?

You can use Stamina mode with push notifications, just whitelist the apps you need working with screen off...

Dont say thanks,Hit thanks ,
Go to stamina mod and add apps you want,like gmail,whatsapp,etc,and then turn on stamina mod
Am using du battery saver pro there you get option to lower CPU frequency when screen is off,
And also I recommend install greenify and put apps which you use rarely,

I also noticed the battery drain after the KitKat update of my device... Previously my device used to last for 1 1/2 day after full charge with a moderate usage. But now with the same usage, Its draining fast and lasting up to evening only...! Is there any way to revert back to Jelly Bean...? My primary concern for buying this phone is 6" display and battery stamina... The kitkat update is eating up my battery...! :crying:

Yes.. The battery drains out quickly
few days after upgrading to kitkat... the battery is draining out quickly.. now i have to charge the battery twice a day... tried to force stop many applications... but no use... please anyone help me....
