root and battery drain

My battery status acts weird.
When I root a rom the status and the battery drains in one hour...
If I flash a samsung firmware the battery drains normally... Even with overcome kernel and stock rom the battery stays at normal drain. When I root the tab the battery flips out. anyone can help?

Try to use "BatteryCalibration" from Market. But first you have to root you device.

Thanks for your try, but I´ve made ´t often...

Battery problems

I am having some battery issues, and I cannot understand why.
I was on JB 4.3 stock and rooted, and battery was working fine. But when I updated my tablet to Kit Kat (I flashed purity rom), my battery drained because of google search. On the battery usage, sometimes it had more than 40%.
So, I flashed CM, because I thought it was probably a bug from the rom. But now my battery drains with google keyboard, it keeps downloading data all day long. If I put my nexus on airplane mode the battery doesnt drain.
Any help would be appreciated,
thanks in advance!

My battery keeps doing funny things.

Hi All,
I've attached a screenshot of the battery settings, my screen-on-time at this point was 1h48m - it seems to not be able to calibrate at all and drops and rises as it feels. I unplugged my phone this morning when the alarm went off and snoozed myself for a few hours, the phone was off when I woke up, when I turned it on it was at 66%
I've reloaded my ROM (MIUI v5) and it doesn't seem to have made a difference. Is it my battery dying or is it the ROM? I haven't seen anyone else using MIUI have these issues.
Any advice? Should I think about replacing the battery?

Seems really bad and battery problems really gets fustrating at times..
Check if you have any apps you recently installed that might be causing the drain (Games tend to stay in background hogging batteries)
Reflash your rom if possible, with a full wipe to be assured of no rogue apps.
If the problem persists, then it might be due to a worn out battery. Replacing the battery usually solves most problems :good:

Hello!
It might not be a ROM issue and it may be actually an issue caused by some apps. Facebook and it's craps, but also Play Services drain alot of battery and also eats alot of memory.
1) Install BetterBatteryStats (aka BBS). There's a free xda version attached at the end of that post.
2) Charge your phone to 100% and unplug it.
3) Use your phone as you did until now and next time you need to charge the phone, open BBS before doing that and check what has drained your battery (wakelocks, alarms etc.).
