iPhone 16 Pro Max — sensor array 0x100000: Charging port flex

Low confidenceVerified sourceSMC: silent sensor

On the iPhone 16 Pro Max, 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; an iFixit Answers reply links 0x100000 (1048576) to the charging port and extends it to the 16 and 17 series, with no confirmed case. With no response, it forces a restart, which repeats roughly every 3 minutes (≈180 s) as long as the sensor stays silent.

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.
