iPhone 15 — sensor array 0x200000: Wireless charging coil

High confidenceVerified sourceSMC: silent sensor

On the iPhone 15, 0x200000 means: Wireless charging coil (MagSafe, 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 sensor carried by the wireless coil flex 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.

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.
