I have an LG G2 - VS980 4G LTE, Android Version 5.0.2. Ever since the last android update, my battery drains every single day. It used to last several days - I would charge maybe once or twice a week. Now I have to plug in every single day. The phone is always shutting off, I am missing calls because it's dead more than alive. I've checked every setting possible, constantly clearing task manager, but nothing helps. Very frustrating. Anybody have any ideas at all? Do I need a new battery? What the heck is going on??
