My iphone xs keeps restarting. iDevice Panic Log Analyzer I used the program and it said it could be one of them, what should I do?
Log : SD: 1 BC: 1 RC: 0 BS: 2, Missing sensor(s): Prs0
I changed the charging socket. I also removed both the face id and the charging socket from the card, but the device restarts again.

disconnect the charge port, if it still restarts try disconnecting the power button and check again

When you disconnect the charging flex. You also disconnect a thermistor. The phone turns on but after 180secs it turns off because it doesn’t know it’s temperature
@deniz keskin did you replace the charging flex with a genuine part or a copy ?
copy charging flex
@deniz keskin some copies don't come with the sensor, try a genuine port
@tech_ni where do you get genuine parts flex?

Hi deniz,
The Prs0 sensor is indeed found on the charging port flex cable, so your instinct to replace the charging port flex was the right call. Were you getting the same error before you replaced the flex, or did the error change afterward? In any case, it doesn't appear the phone is able to read the sensor on the replacement part. There are two logical possibilities as to why; either the new flex cable doesn't have or incorrectly implemented that sensor, or the problem isn't on the flex cable, but rather on the motherboard. If it's a motherboard issue it could either be the connector or the chip that handles the I2C communication to the sensor.
@flannelist has written an excellent guide to iOS kernel panics that's worth your time to take a look at.
I'd suggest you use the guide to locate the panic log(s) on the phone and either screenshot or cut and paste the first page or so of any and all the logs that are present so we can take a look at them; there may be more to them than what your analyzer is showing; i.e., there might be more at issue than just the one sensor.
Add that information to your question and we'll take a look and figure out what to do next.

I've personally changed out a few charging port assemblies and never had an issue with aftermarket parts, but you never know. In the absence of any more information I'd probably just bite the bullet and replace the port again, perhaps find one that has good ratings by users.
Let us know what you find with regard to the panic logs.

thank you for this great answer. I have now ordered a better quality charging flex. The sub-industry charging flex was causing the freezing problem in the device. Let's see if I can fix the problem
Could you fix it changing the charging flex? I also have the same problem.
@ernestotos26468 Absolutely; that is 100% the most common fix for this problem and in almost all cases replacing the charging port flex will eliminate the kernel panic.
