tb0v — Missing sensor

Watchdog panic: thermalmonitord no longer receives readings from the TB0V sensor, which iPad Rehab lists among the battery sensors; with no news from it for ~3 minutes, iOS restarts the iPhone, in a loop as long as the sensor stays missing.

First check

Check whether the battery percentage is displayed (a reading stuck at 0–1% reveals lost battery data), inspect the battery connector (bent pins), test with a known-good battery, then measure the connector's data lines in diode mode.
