iPhone 13 — sensor array 0x1800: Charging port flex + front sensors flex

High confidenceVerified sourceSMC: silent sensor

On the iPhone 13, 0x1800 means: Charging port flex + front sensors flex (two simultaneous faults).

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, two sensors are missing at the same time: charging port (0x800) and front sensors (0x1000). 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?

Deal with both parts: check/test the charging port flex AND the front sensors flex with known-good parts.
