Personally, I'd like to know when I can just fix something instead of getting an entirely new one. "This thing is mysteriously slow, so I guess I'll get a new one" is much more profitable for apple, and more user hostile than "You're phone is slow because the battery is old. It' x% slower now than at purchase". So in my view, it's a dark pattern.
