This is the same as the iphone 5 battery replacement program that was started in 3/15 18 months after they went on sale. My iphone 5 did the same thing as these phones. It would change levels instantly and shut down early everytime. I thought it was the cold weather causing it . In 1/15 i ordered a battery from ifixit and changed it myself. It fised the problem. 2 months later apple offered to fix all the affected iphone 5 and pay back all who had paid someone to change the battery. I was not included because i did it myself. I paid for the battery and tools. I was told that i voided the warranty on my phone that was already out of warranty by 4 months in 1/15 . I bet the same game goes on with this battery program.
