i've rooted my phone a while ago and had no problems with quick battery drain...it started this yesterday i unplug it from charging..and an hour later i've got one bar left..its done the same today...how do i fix this?
Try fully charging. While it is plugged in, restart in Recovery. Go to the Wipe menu, then Wipe battery stats. Restart the phone; unplug as soon as you see the ROM's splash screen. Leave it unplugged until it is as close to drained as possible.
Let's see if the battery stats were bad or something.
