iPhone 16 — sensor array 0x80000: Charging port flex

Medium confidenceVerified sourceSMC: silent sensor

On the iPhone 16, 0x80000 means: Charging port flex (USB-C) / barometric pressure sensor.

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 sensor in the charging port assembly (the lower microphone module / barometric pressure sensor must be connected) 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. Code shown in decimal in the log: 524288.

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.
