I searched the internet on a method to backgrade or back out from marshmallow to lollipop or kitkat on Verizon LG G3...NO JOY! The only way I get through the day is with a 6000 ma/hr battery pack. I have done every solution suggested eg several factory resets, greenify app battery savers etc. All these are band aids and not cures or solutions to the ill advised OS 6 Marshmallow upgrade being pushed by Verizon to a LG G3 that can not handle it. I am now very close to my solution which is a new free Verizon phone (? LG G4/5) that will work OR I will very reluctantly port over to AT&T which will give me a new free phone and cover all fees and contract penalties
