Reasons for mobile phone charging heat:
① The processor is a mobile phone heating consumer: the processor, that is, the mobile phone CPU, is a highly integrated SOC chip.
It not only integrates the CPU central chip and GPU graphics processing chip, but also a series of key chip modules such as Bluetooth, GPS, radio frequency, etc. It is the most integrated chip in the smartphone chip, and the module will dissipate a lot of heat when it operates at high speed.
② Hot battery when charging: during the charging process, the power supply circuit is in operation when the resistance is working, the resistance and the current are playing with each other, and the heat is definitely inevitable, and mainly concentrated on the battery and the internal PCB motherboard.
In the winter when the ambient temperature is not high, mobile phone charging may rarely lead to serious heat of the mobile phone, but in the hot summer, due to the increase in the ambient temperature, coupled with the heat generated by internal charging during charging.

Suggestions to solve mobile phone fever:
(1) Avoid charging, playing games, watching videos or making phone calls;
(2) When using the mobile phone for a long time, avoid the mobile phone close to the cheek, and try to use headphones or earphones;
(3) Try to close the background program of the mobile phone to reduce the burden of the mobile phone, thereby reducing the fever;
(4) Turn off automatic download, automatic update and other functions to reduce unnecessary program update installation;
(5) Avoid using the mobile phone protective case with poor heat dissipation or remove it when it is hot.
1. The battery has a life, and with the growth of mobile phone use time, the battery may age, resulting in hot charging.
2. The charger is not the original charger, the current and voltage specifications are not consistent with the mobile phone, and it will reduce the battery life while heating.
