Why is "Andriod System" usage so high and draining my battery. Im a Flight Attendant, so my phone is mostly in airplane mode.i unplug it at the hotel fully charged and within 4hrs my phone drops to 65% in battery life. What gives? If i cant have a working phone then Verizon needs to allow me to upgrade. My work gives us a IPhone 6 plus and that last me all day long in battery life. If i have to buy a new phone so i can have a reliable phone, will Verizon allow me to upgrade early??
