You can blame the battery life indicator for it While it's nice to know how healthy it is, it's guaranteed to become one of the first questions asked by your potential second-hand buyer. And god forbid it's anything lower than 99% because if it is, prepare for a bargain war. It may not be a big deal today or tomorrow, but in a year or two, things will change, for sure Whenever I sell my used Mac, the first question my buyer asks is warranty, the second - battery health Expect the same with iPhones very soon And if you think that most won't even know such a feature exists, even the ignorant learn eventually P.S. Just to be clear, I’m not upset about the feature. Am merely pointing out that it may affect the iPhone resale market in the future.
