Keep in mind that the check done inside an iPhone doesn't prevent the failure mode you describe. After all the phone only checks the microcontroller attached to the battery, not the actual cells(if that's even possible in any way).

It isn't, but there are some controller circuits that switch off permanently if the voltage falls out of range, making changing cells more difficult.
