I am buying an used iPhone X running iOS 16.7.8 that supposedly had a brand new battery replaced by Apple according to the seller. However, in the settings, there was no service record at all, including one stating that there was a genuine battery. This is true whether or not iCloud is signed in or not with the original owner’s ID.
I seem to recall that service record for the device can be seen under iOS 15.2 and higher, even for iPhone X (not just for iPhone 11 and higher). Can someone elaborate on this?
