Now I'm currently on 5.1.3.0 and my battery cant even hit 4 hour screen-on time. (It was even worse in 5.1.12)
But a few months ago my battery life was normal, and i'm sure that I dont have any viruses, and the health of my battery is good.  What can I do? What can cause this? Do you guys have any problems with the battery? Im tired of using a 1 year old firmware. Somebody said that quickcharge might be the cause, but i dont know how to turn that off.
