So I have an iPhone 6s on the Apple Upgrade Program. I'm within my return period. I want to take it back to the apple store and have it exchanged for another one because I believe my battery is defective. It's behavior is not consistent with anyone else's i've seen, it is draining incredibly quick with very few background refresh apps on and not heavy usage. (for example the other night it hit 20% and I put it on low power mode. in less than an hour - probably 30-40 mins - it had dropped to 15% just sitting in my pocket. again on LOW POWER MODE.) So what is the process? Will they just scan mine back in and scan me a new one and that's it? Or will they have to cancel out the whole financing agreement, refund my money, and then start the process all over again, re-checking my credit and all that? I'm sure some of you have done this for the whole Samsung to TSMC swap, so I'm wondering what the experience is. Thanks! edit - and I'm on Verizon if it makes a difference.
