Hey guys I've had completely terrible battery life forever on my phone and im done with it. I can only get 1h 30 mins of screen on time MAX. it usually gets to 30% by 3:00 in the day (I unplug it at 730) so only six hours of decent battery I have wifi usually enabled and brightness at low ALL the time I am running STOCK 4.3. I have Gsam battery installed and my top battery draining things is the Kernel OS and android system Is this a problem with the OS? my battery? thanks!
