> Throughout iOS, people—not apps—are in control. An app can suggest a course of action or warn about dangerous consequences, but it’s usually a mistake for the app to take over the decision-making.
See also various UI guidelines from Microsoft at times when not a single MS app that was profitable followed those guidelines.
Of course implying that there are only two possible solutions to this problem is exactly what Apple wants you to think. It's kind of like Kevin Spacey raping minor boys and saying "okay, you caught me - I'm gay," to avoid any real consequences. It's misdirection.
There are two real solutions to this issue, none of which is being offered or hinted at by Apple:
1) increase battery size to match that of competitors (so up to 2x from what it is now), making the lower battery life over the years a much smaller problem for users
2) compromise a millimitre of thickness and allow users to replace the battery on their own, especially now after Apple gained more space by giving up the audio jack.
But of course Apple doesn't want you to think of any of these. Instead it wants its customers to keep fighting over the "Battery or Performance* faux choice.
