The most common for iPhone 15 series are:

Back Glass/Wireless Charging Flex- This is the flex that is attached to the Back Glass. It can damaged during a drop or screen replacement
Proximity Flex -This is the flex that is attached to the screen. It can easily be liquid damaged or torn during a screen replacement.
Charging Port Flex - This is the flex towards the bottom of the phone. It is easily damaged with a drop & the back glass is breaks. Or when someone has repaired the back glass.


After a back glass repair, the iPhone will restart on its own every few minutes
After a hard drop, the iPhone will restart every 3 minutes.
After a screen repair, the iPhone will bootloop every 3 minutes
The iPhone will reboot randomly when using it.
The iPhone will seem to freeze and restart every 2-5 minutes.
Diagnostic Steps
Before you start blindly replacing parts, it's important to try to confirm what is causing the restarting issue by reviewing the Panic Log file. This is a file that is generated by the Operating System, to document the fault causing the restart.


An example of panic log files you'll find in the iPhone when it has been randomly restarting.
To find the panic log on the device, go to Settings-> Privacy-> Analytics & Improvements-> Analytics Data->
Scroll down to the files starting with "panic-full..." & click on the most recent dated file.

Then you'll want to scan through the text for keywords that may point you to the cause.

For this model, look for where it says "SMC PANIC - ASSERTION FAILED" ... "Sensor Array" .. "0x...."

If you see:
0x200000 (or 2097152) - it's the Wireless Charging Flex (Back Glass)
Make sure it's plugged in & the flex is not torn
Check that there's no liquid damaged, or that it's defective
Test with OEM or Premium. Aftermarket Flexes have a high defect rate
Diode mode the FPC connectors for any faults
Could be a sandwich issue
0x80000 (or 524288) - it's the Charging Port Flex and/or Air Pressure Sensor
Make sure this flex is plugged in
Make sure the Air Pressure Sensor is plugged in
Check that no flex is torn, liquid damaged, defective
Test with OEM or Premium. Aftermarket parts have a high defect rate
Diode mode the FPC connectors for any faults
Could be a sandwich issue

Diode mode the FPC connectors for any faults
0x280000 (or 2621440) - it's the Wireless Charging Flex + Charging Port Flex
Make sure both flexes are plugged in
Check that no flex is torn, liquid damaged, defective
Test with OEM or Premium. Aftermarket Flexes have a high defect rate
Diode mode the FPC connectors for any faults
Could be a sandwich issue
0x380000 (or 3670016) - it's the Wireless Charging Flex + Charging Port Flex + Proximity Flex
Make sure all 3 flexes are plugged in
Check that no flex is torn, liquid damaged, defective
Test with OEM or Premium. Aftermarket Flexes have a high defect rate
Diode mode the FPC connectors for any faults
Could be a sandwich issue
0xa1 (or 161) - It's a battery data issue.
Sometimes you'll see the battery percentage fluctuate or you'll randomly get a "non-genuine" message.
Check the battery connector pins. Sometimes they can bend out & battery won't make good contact.
Diode mode the battery connector pins & compare them to known good board
Test with a known good battery
Replace the battery connector
Check battery connector voltage.
