[Q] Issue with batter life, root or not?
I have an i9505 for a month and it's great.
the problem is if no wifi, Bluetooth, gps and ... ON, I have around 15% battery drain from 12:00 am to 7:00 am.
I had an Htc before and it was dual core 1.5 Ghz and it's at night battery drain was around 3%.
the only thing which is annoying is this. I already turned off most of the Samsung programs but no difference.
I don't know what to do? If I root my device and use a custom ROM would be any difference?
