So I was having issues with the battery in my 6S, it would shut off at various random percentages, claim the battery was empty then an hour or two later be able to be powered on fine (or if plugged in would turn on at the percentage it shut off at like 60% or 40%). I made a call to Apple Support and they setup a repair which has just been returned to me. The slip of paper inside says that the iPhone was sent in because of Display issues and the repair was to replace the Display Assembly. I had made zero mention of display issues. Before I start chasing Apple on this / beginning the slow process of restoring the phone: Does anyone know if the battery would also have been replaced as part of the repair process? I can see that they phone has certainly been returned to an earlier version of iOS than I had on there before (was iOS 10.1 beta 2 now 10.0.2).
