Why does the system experience lag as the Redmi 13C 5G temperature rises?

Several factors will cause a temperature rise of the Redmi 13C 5G, such as running intensive applications, environmental temperature, battery issues or network usage.
The reasons for lagging caused by temperature rise are listed below:
1. During the use of the phone, the system will gradually limit the CPU frequency as the temperature rises. High-temperature frequency limiting measures will solve the problems of system lagging, which will release your feeling of heating, prevent severe heating during phone use, and extend the phone's use life;
2. If there is a high-temperature lag phenomenon, high-load processes running in the background (such as charging, downloading, flashing, Wi-Fi hotspot, etc.) will be turned off.
