If apple was being honest they would have some interface to show the battery life. When I upgraded iOS recently I got a notification saying "hey we only charge your battery to 80% now to preserve its life." That was fine and appropriate! So it's not like Apple can't do that. But if my phone had just stopped charging to 100% with no notification I would have been annoyed. Same thing here, especially since theres a fairly obvious conflict of interest in that slowing down old hardware is very useful for continued revenue. I just want a screen that says, hey, you're running at 70% speed because your battery is now garbage.
