Every since the new software update came down on Dec. 02, 2015 my LG G4 battery time has sucked. It takes 6-8 hours to reach a full charge and I get about 21/2 hours of standby time from that. I have noticed no enhancements from this update whatsoever. I would guess that the new surveillance software is eating up all of my battery. Can I remove this update or can you fix my phone. It worked great until this so called enhancement software update. This phone and battery are only 2 months old. The battery heath monitor says the battery is fine. When I do use it I have to clear all apps otherwise they will bleed the battery dry in no time. Suggestions please
