iPhone Air — sensor array 0x2000000: Wireless charging coil
Low confidenceVerified sourceSMC: silent sensor
On the iPhone Air, 0x2000000 means: Wireless charging coil (back glass).
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 wireless coil flex sensor has stopped responding (decimal value 33554432). 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 wireless coil flex (back glass) and its connector: seating, creases, corrosion; test with a known-good back glass/coil from the same model.
