Hey everyone, If this has been answered before i sincerely apologize. I do not even know how where to start as this is my first new iphone experience. This 6 was my wifes and she upgraded to the 7 because she was having terrible battery issues. I recently started using it and now know she wasnt making it up. Was just on a call at 35% and the phone complete shut off. Plugged it in and it booted up at 26% already. I dont even know how this can happen. when i first got it i tried the "charge it all the way and let it discharge all the way" thing but that didnt really help anything. Again, sorry if this is the dead horse topic, my apologies for beating it. Thanks in advance for all advice.
