I used to be simply questioning about how an Apple iPhone is aware of that you simply aren’t an authorized service supplier when, for instance, you exchange the battery. I am conscious that it checks the serial variety of the battery when it boots and compares that to the earlier battery, however what steps does an “official” service vendor undergo to make sure it is aware of that the substitute was official? Is there particular {hardware} that they plug into the Lightning port/pins contained in the system?
