Hot mobile phones are generally normal, but if they overheat it may negatively affect the phone's performance and battery life. If the phone overheats, it is recommended to suspend charging and allow it to cool down for a while. At the same time, ensure that the charger and charging pad are well ventilated, and avoid using the phone for a long time or charging in a high temperature environment.
If the phone is frequently overheated or hot, there may be hardware problems, it is recommended to consult Apple customer service or go to a professional repair point to check.
