Do you remember when the iPhone 6/6s were shutting down with nearly a full charge. They had a battery replacement deal and then a software fix that seemed to solve the problem. Well, mine had those problems then, and then with the software update it quit having the problems. Now it is doing it again ... literally out of the blue! It went from going a whole day on a full charge one day and then the next day it now dies after about 5 minutes off of the charger (or less). Is anyone else experiencing this?
