Original parts return
Is apple obligated to return original parts when performing non-warranty customer paid for service on a customer owned device? I.E...the original battery for my iPhone 8 which I paid to replace this eve. Apple verified the battery was fully functioning w/81% life yet when I requested the original battery (I own the phone) be returned to me after paying for a new battery, the apple store refused to return my original battery.
iPhone 8, iOS 14
