iPhone 13 Pro Max - restarts every 3 mins / Sensor 0x800

On previous model iPhones the errors are more specific; in particular there are two sensors known to fail on the charging port assembly; one is labelled mic1, but it's not clear exactly what the sensor associated with the microphone does. It may indeed be possible for the sensor to fail but the microphone works fine.

Secondly, there's another sensor called PRS0 that has to do with the barometric vent at the bottom of the phone; PRS0 is commonly understood to be a reference to a pressure sensor.

However, as of the iPhone 13 model, the distinction between those sensors is gone and you only get the indicator that the charging port is bad. In your case, for example, if the PRS0 sensor has died then sure your charging port and microphone will still work fine while the phone lives it its eternal boot loop.

As Mr. Lex has already suggested, replacing the charging port will almost certainly fix the problem. I have replaced the charging port assembly on an iPhone X due to that sensor and it did indeed resolve the issue.

@rizz2greedy, Unfortunately it sounds like a motherboard issue. Assuming you're getting the exact same error even in a different chassis, that points to a problem with the I2C bus communication between the processor and the charging port. I2C consists of two signal lines, a clock and a data line, and those two don't just go to the lightning connector assembly, but travel through paths on the motherboard. Any component that fails along the way such as a resistor or capacitor can disable the I2C bus and cause that kind of failure.

While that sort of issue can be repaired, it does require specialized equipment and expertise that not many repair shops have. You might try iPad Rehab as one source, but look through the business listings here on iFixit to find other options as well.

I have the same problem with the 0x800 sensor. I had dropped my phone and there were two cables behind the broken glass that poke just out of the shielding behind the phone. If its the backglass facing towards you with the cameras on the top its to the bottom right. I had been touching those wires and one of them broke off lol. My mic doesn't work when it's connected to speakerphone. Same thing with voice memo, however recording using the camera it picks up my mic. The proximity sensor still works too and the charger is fine as well.

I will replace the charger assembly but would be open to possible answers.

Just wanted to add a little addition to the topic. It is confirmed that, if replacing charging port flex doesn't get rid of the issue, then its a motherboards problem. If you trace pins on the charging port connector - two of them are connected with the interposer pads, which continue to the CPU. In case of cracked joints on either of these pads, the error 0x800 will show. What I did is just reflowed the entire motherboard on the preheater plate (without splitting) and the restart issue is now gone.

happy fixing!

Hi I’ve tried everything to resolve the 3mins restart , even putting logic board in another iPhone 13 Pro Max frame but still it restarts every 3mins. I’ve tired charging port replacements and battery replacements. What else should I try or what can I do
