It's normal for Apple wireless charging phones to be hot.
The working principle of wireless charging is to convert electrical energy into electromagnetic waves, and then electromagnetic waves will import electrical energy into the inside of the mobile phone, this process will produce a certain amount of energy loss, but also produce a certain amount of heat. However, if the phone is overheated for a long time while charging, it may cause certain damage to the battery and circuit inside the phone. Therefore, it is recommended to choose a wireless charger with reliable quality, and pay attention to whether the heat of the phone is moderate when charging. If the phone is overheated or even hot, it is recommended to stop charging and check the quality of the wireless charger, and confirm whether there is a quality problem. In addition, if the phone often appears hot when charging, it is also recommended to reduce the frequency of using the phone when charging, so as not to increase the burden of the phone.
It is not normal for the phone to be very hot when Apple is charging the phone wirelessly. In general, the phone should be warm when wireless charging, but it should not be very hot. If the phone is very hot, it may be caused by too much power of the wireless charger or a problem with the phone battery. It is recommended to check whether the power of the wireless charger is appropriate first, if the power is too large, you can try to reduce the charging power or suspend the charging, and let the phone cool down before continuing to charge.
If the phone is still very hot, there may be a problem with the phone battery, it is recommended to stop using the wireless charger, and contact Apple's official after-sales service for overhaul.
