iPhone 15 Pro — sensor array 0x100000: Charging port flex

High confidenceVerified sourceSMC: silent sensor

On the iPhone 15 Pro, 0x100000 means: Charging port flex (USB-C).

What does this code mean?

SMC “BSC failure” panic: the system management controller (built into the SoC) periodically waits for a response from each mandatory sensor; here, the charging port flex sensor has stopped responding. With no response, it forces a restart, which repeats roughly every 3 minutes (≈180 s) as long as the sensor stays silent. Value recorded in the lab by disconnecting only the USB module (DFRWS 2025).

Which part to test first?

Check the seating and condition of the charging port flex (tears, corrosion, FPC connector pins), then test with a known-good genuine flex; if the panic persists, measure the connector pins on the logic board in diode mode.
