1, because there is a temperature detection system in the circuit design of iOS devices, and there is a complete temperature protection mechanism. The iPhone has NTC, short for Negative Temperature Coefficient, embedded in several circuits. It means negative temperature coefficient.) A thermistor.
The resistance value of NTC thermistor decreases with the increase of temperature. This feature can be used to make an iPhone internal temperature detection sensor to detect the internal temperature of the iPhone. When the temperature is too high, the iPhone enters the protected state, and stops all programs until the temperature drops to the normal temperature. The overtemperature protection mechanism can effectively protect the iPhone motherboard circuit and the original to avoid the original from being damaged by its own fault. How to solve 1, application problem. This can happen because there are too many apps or games open and too many tasks running in the background. An application or game uses too many hardware resources and generates too much heat. Try closing some apps and restarting your iPhone.
2. System problems. It is possible that the iPhone is using a beta version of the system, and due to the imperfect system, the phone consumes too much power and generates too much 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.
