I bought this Motorola phone some months ago and it is not showing performance as a 3900 mAh phone should. It dies almost really fast.no gps in, not extra apps( in fact disbled some not-uninstalleble apps), no wifi location on, no improvement message sending, absolutely no nothing. But I think I kinda figured out what was draining the battery: wifi screen and chrome. But I have no idea how to fix it.any help?
