Apple typically offers an easy way to identify whether you may have the faulty part, such as with a range of serial numbers, though it didn't this time. The company also didn't offer more detail about how many iPhones it believes may've been affected, though it did say no other iPhone models are part of the announced repair program. The company didn't respond to a request for comment Friday evening.

This isn't the first time Apple has offered a repair program for its iPhones. In September, the company said a "very small percentage" of iPhone 8 devices had faulty logic boards that led them to unexpectedly restart, freeze the screen or not turn on at all. And in February, the company said a small percentage of iPhone 7 devices contained a faulty part that would lead the phone to tell people there was no cell service when in fact there was.
