Parts serialisation on Apple iPhones


Unfortunately many parts in Apple devices are now serialised. Individual components are paired to the logic board.

This means that the device will recognise a replacement part, and register it as an "Unknown Part" in service history.


iPhone parts and service history - Apple Support

Even if we bought a brand new iPhone and swapped the battery over, it would still register as an "Unknown Part" because it does not have the original coded data.

Unfortunately Apple does not provide access to their recalibration software, so we cannot remove this message.  

Affected components include: 

  • The screen on iPhone 11, 12, 13 and 14 series.
  • The battery on iPhone XS, XS Max, XR, 11, 12, 13 and 14 series, SE 2nd and 3rd gen.
  • The rear camera on iPhone 12, 13 and 14 series.

Apple does not sell spare parts. Here's what we do...


For screens, we offer original refurbished displays and high quality compatible displays. You can read more about these options here.

For batteries, we use high quality aftermarket batteries, which have an identical rating and capacity as the original battery, and perform just as well.
We can purchase original refurbished batteries, but these are not as reliable in our experience.

For rear cameras, we usually opt for original pull components when available. These are original working camera modules that have been removed/harvested from iPhones.

All of these replacement components come with a 12-month warranty to protect against defects.

We strive to deliver an affordable and reliable repair service to our customers in spite of Apple's efforts to suppress third-party repair.

Here is a detailed breakdown by iFixit on measures taken by Apple to make their devices more difficult to repair.
