1, mobile phone motherboard heating is generally overloaded work, there may be short circuit. If you do not play with the mobile phone is also very hot is the main board circuit board short circuit, this to after-sales maintenance. 2, open too many applications, is a dozen applications, and then the memory does not end the operation, so the mobile phone will be tired, tired certainly heat.
3, the optimization of the system is not enough, or the optimization of the Android system is not enough.
Solution:
1, don't play with your phone while charging. When charging while playing with the mobile phone, the burden of the battery of the mobile phone is increased, and the heat is difficult to avoid in the working state of this large current for a long time. So don't play big games while your phone is charging. And it's not safe to charge your phone.
2, do not open too many applications, unused applications can be closed. This can not only improve the speed of the phone, but also reduce the loss of power, while avoiding the phone heat.
When the mobile phone is fast charging, the motherboard is hot, it may be that the fast charger you use does not match the mobile phone, so the motherboard will be hot, and when this problem is serious, the mobile phone should be stopped in time to charge or change a charger to try it, and the original charger that matches the mobile phone should be used when using the charger
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 you are conducting wireless charging, 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, this is normal
During the charging process, the resistance is working when the power circuit is running, the resistance and the current are playing games with each other, and the heat is definitely inevitable, and it is mainly concentrated on the battery and the internal PCB motherboard.

In the winter when the ambient temperature is not high, the mobile phone charging may rarely cause the mobile phone to be hot, but in the hot summer, due to the increase in the ambient temperature and the heat generated by internal charging when charging, the internal temperature and the ambient temperature are not large enough to reduce the heat dissipation efficiency, which will naturally cause the mobile phone to be hot.
