Mobile phone charging heat is very hot what reason?
① The processor is a big user of mobile phone heating
The processor, that is, the mobile phone CPU is a highly integrated SOC chip, which not only integrates the CPU central chip and GPU graphics processing chip, but also a series of key chip modules such as blue, 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.
Generally speaking, the mobile phone processor is equivalent to integrating the CPU and the graphics card module at the same time, and also contains some other modules. Friends familiar with the computer know that the CPU and graphics card are hot, the two are fused together, plus a small chip module, the heat is naturally the largest, so it is very easy to understand.
② Hot battery when charging
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.
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.
