I've had this lg g4 for a few days now and the battery life isn't all that great. Today I've been using it quite heavily but looking at the battery usage my screen is over 50%. To me that is just not normal at all. Right now I'm at 40% with almost 8 hours of usage since last charger and I have an estimated 6 hours remaining with the screen taking up 52% of the batteries usage and just over 2 hours screen on time. Any ways to fix that?
