It is normal for mobile phones to generate a certain amount of heat during charging, but if excessive heat occurs, it may be due to the following reasons:
First, the charger and data line are in poor contact, and the current can not be transmitted, resulting in excessive heating of mobile phones and other devices.
Second, the charging efficiency is low, the charging time is too long, and the heat of the mobile phone is released in the form of waste heat emission, which affects the battery life and mobile phone performance.
Third, the use of inappropriate chargers, data cables, power is too high or too low, may cause damage to the phone, produce abnormal heat. The use of appropriate chargers and data cables, as well as reasonable control of charging time, is an effective way to avoid excessive heating of the phone.
Heat is a common phenomenon when charging mobile phones, especially support fast charging, super fast charging mobile phones, when charging, the current and voltage are larger, so the temperature will be higher than ordinary charging.

If wireless charging is being carried out, because there will be energy loss in the wireless transmission process, and then generate a certain amount of heat, there will be a phenomenon of heat when wireless charging, which is normal
Mobile phone charging heat is the problem of battery aging, if you find that the mobile phone charging heat, should immediately get the mobile phone repair shop, open inspection, most of the battery problems, replace the battery can be solved.
