iPhone 14 — sensor array 0x500000: Charging port + wireless coil

Medium confidenceDisputedSMC: silent sensor

On the iPhone 14, 0x500000 means: Charging port + wireless coil (DFRWS test) — or battery according to iFixit.

Sources disagree on this code. Both readings are shown: confirm with a known-good part.

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; the value 0x500000 matches, bit for bit, charging port (0x100000) + wireless coil (0x400000), a combination reproduced in the lab; iFixit and iPad Rehab, however, attribute it to the battery. 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?

Start with the charging port flex and the wireless coil flex (seating, corrosion, known-good parts); if nothing changes, test a known-good battery and measure the battery connector in diode mode.
