iPhone X High Temperature Shutdown
Posted by
Fixing iPhone X with high temperature shutdown has two cases:
- The machine heats up during use or touches the IC, so the temperature should be reported.
- Machine does not touch. The power-on line is normal, but it's just started up for a while.
In the first case, it can be called correct, because a component near the area has hot thermistors, so the thermistor changes value and the temperature alarm. At this time, it is necessary to identify the touch IC and handle it (If there is a functional error, check which IC manages the faulty function)
The second case is that the machine is completely cool but the temperature is reported, it is called a virtual alarm. At this time, one of the thermistor pairs arranged on the main board is faulty, so the machine always understands that it is hot.
