> Adding code and microchips to enforce serial paring of batteries, screens and camera modules to the device it was originally installed in... is a cost cutting measure? This absolutely can be the case. What is the engineering cost of supporting third party components? What happens to apples image if a crucial calibration is not performed after swapping a component? They might lose that customer forever because “Face-ID doesn’t work”. What is the cost if your PR image is damaged as a result of third party battery fires? “iPhones explode” would be the headline and third-party batteries would be the footnote.
