This is because there is a temperature detection system in the circuit design of iOS devices, and there is a complete temperature overtemperature protection mechanism. Cause analysis and solution;
1. Too much open software, too many background tasks, and too much heat caused by a program occupying hardware resources. For example, navigation, video recording and other applications can be closed or restarted.
2, the use of beta version of the system, due to the imperfect system, resulting in high power consumption of the mobile phone, large heat. Restore the system to the latest official version.
3, hardware damage, due to liquid intake, external force and other human factors caused by NTC thermistor damage or chip damage short-circuit caused by temperature detection system damage. Example Damage to the NTC thermistor and power management chip will cause the iPhone to enter the overheated protection state. At this time, what the user needs to do is to shut down the equipment and send the equipment to a professional maintenance organization for maintenance.
