Re: Why does my phone charge good with certian chargers
may be there is a problem with plugging issues? or battery issues? check them too if not buy g4 charger instead of g3 some charges wont accept even though they are of same model.
Most probably its because of cache ! its wise to remove apps which say they clean cache but indeed they do it temporarily. faced same problem but its genuine and long back faced same issue and figured myself!
