iPhone X — prs0: Charging port flex
High confidenceVerified sourceMissing sensor
On the iPhone X, prs0 means: Charging port flex (barometer).
What does this code mean?
Watchdog panic: thermalmonitord no longer receives readings from the Prs0 barometer, mounted on the charging port flex; with no response for ~3 minutes, iOS restarts the iPhone. Typical after a back glass repair (exposed flex) or a charging flex replacement.
Which part to test first?
Test with a known-good genuine charging port flex; inspect the resistors around the flex connector on the logic board.
