Why is the mobile phone overheating seriously in standby under the 5G network environment?

Solution:

At present, the 5G networks in various cities in China are still under construction, and the base station density and network coverage are low, which is prone to weak 5G signals. The mobile phone will increase the transmission power of 5G accordingly, and the increase in system power consumption will cause the mobile phone to heat up. Therefore, it is recommended that you turn off the 5G network switch in the settings when you are not using the 5G network. Settings--Dual SIM and mobile network--5G network (set to off).
