Why does the new phone get hot within a week after purchase?

Solution:

MIUI is a highly customized system with a large number of functions. The new phone will go through the process of restoring data, updating the system version, etc., and there is a certain heat phenomenon. At the same time, in order to use all installed apps more smoothly, they will be compiled after the download is completed, and the cloud data will be synchronized centrally, so the power consumption in the background is high, and the temperature rise will return to normal after the phone completes all initial configurations. It is recommended that you observe and use it for a while time.
