Since I have installed kitkat ( b510, b511 and now b512) after my battery gets to 9%, it drains so fast, in 1 minute with the screen on, is at 4% and after just 20-40 seconds, is shutting down. I have sync on, a bunch of notifications, but really, 9% in 2 minutes.
The battery life is not perfect, but from 100% to 9% i have to say it drains normally .
I am the only one who is experiencing this? What can i do about it?
