iPhone 16 Pro — sensor array 0x200000: Charging port flex

Low confidenceVerified sourceSMC: silent sensor

On the iPhone 16 Pro, 0x200000 means: Charging port flex / barometric pressure sensor (uncertain attribution).

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; Repair Wiki groups this value (2097152) with 3145728 under the charging port; an iFixit thread on a 16 Pro Max with this code has no confirmed diagnosis. 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?

Work by elimination with known-good parts: charging port flex (and pressure sensor), front sensors flex, wireless coil flex.
