My iPhone 15 Pro won't charge, and tapping Settings on the message shows an unknown part warning. I bought it new and haven't replaced the battery or any other parts. Battery health was last at 83%.
Is there anything to check before considering a battery replacement?
I'd contact Apple Support or take it to an Apple Store for diagnostics before deciding the battery needs replacing. An unknown part warning can point to a problem with battery identification, but it doesn't establish the cause by itself.
If the phone still has enough power, back up your data and make sure you know your Apple account password before taking it in.
Can you still see the maximum capacity in Battery Health? Also check exactly what the warning says in Settings. The previous 83% reading is useful context, but it doesn't explain on its own why charging has stopped.
