Why does the REDMI 14C heat up during use?

Severe heating during use can be caused by several factors, including poor network conditions, multiple background APPs, high ambient temperatures, or the use of power-intensive APPs. Keeping the screen brightness at a high level consumes more power, which can lead to heat generation. Prolonged use of the screen, especially for video playback or gaming, can increase heat due to continuous backlight activation.
To mitigate heating, it is recommended to clear unnecessary background APPs, use the device in a smoother network environment, and reduce screen refresh rates.
