I agree, it was the right call to make -- a temporarily-impaired device is always better than a temporarily-failed device, especially when you're talking about something you may need in an emergency situation.

That said, Apple _significantly_ erred in not over-communicating what they were doing. At that point, the OS would pop warnings to users if the phone had to thermal throttle, and adding a similar notification that led the user to a FAQ page explaining the battery dynamics wouldn't have been technically hard to do.
