So, if you own an iPhone XR, or an XS model or newer with iOS 15.2 and later (including iPhone SE 2nd and 3rd generation), if you have the battery replaced by a 3rd party repairer, you will see a message on your iPhone stating "Unknown Part - Unable to determine if your iPhone battery is a genuine Apple part".

Apple have started to serialise their parts including the screen, the battery and from the iPhone 13 upwards, even the rear camera.
There was only one way of stopping this message which meant removing the BMS (Battery Management System) board from the old battery and attaching that to the new battery. This included spot welding the BMS board to the new battery. It was a bit of a faff to do this and most repairers didn't bother doing it.

But now there are newer, modified batteries available for most of the newer iPhones. These batteries allow the repairer to remove the old BMS board from the old battery and simply plug it into an additional port on the new modified battery. This allows the iPhone to communicate with the existing BMS board, fooling the iPhone into thinking it has the existing battery information (via the existing BMS board) whilst having the benefits of a new battery.

These newer batteries are slightly more expensive than the exisiting aftermarket batteries and require a little more extra work, so these will be slightly more expensive to replace. But at least this should stop the non-genuine battery error message.

Also, as it states on the Apple website, "These messages don't affect your ability to use your iPhone or your battery".
