When a cell phone is charging, the battery heats up. The \"hot\" temperature is only 40 or 50 degrees, which is normal. But if the hot hand can not hold the case, the temperature is 60 ° C, the chip temperature in the machine may reach 70 ~ 90 ° C, at this time immediately stop charging. Unplug the power cord, find out why, then let it cool down and try again.
1, when the battery is charged, the electrical energy is converted into chemical energy process, the molecules, ions and electrolytes in the pool undergo chemical reactions, and some of the energy will be converted into heat. Some mobile phones with fast charging function will have this \"high heat\" phenomenon;
2, when the phone is charging, the normal temperature of the case is between 40 and 50℃. Overheating is not normal, so be careful. Feel not hot, to look at the mobile phone battery status indicator icon, if there is no \"lightning\" symbol, it means that the charging task has not been executed. The charging cable may not be plugged in properly;
3, of course, the ambient temperature in winter is low, the heat dissipation conditions of the mobile phone are improved, and the mobile phone charging is not felt \"hot\
The mobile phone heats up seriously when the magnetic charging treasure is charging, which is right, because the magnetic charging treasure is an electromagnetic charging mode carried out by the magnetic generation phenomenon. When the electromagnetic induction is promoted, it will generate a lot of heat when working, and the electromagnetic induction phenomenon on the back of the mobile phone will also work at the same time, so if the two electronic coils work at the same time, the whole mobile phone will heat up very seriously. Generally take more than twice the heat rate.
It is not normal for the charging treasure to be hot when charging, it means that the current or voltage is too large, if the charging treasure is very hot for a long time, be sure to replace the data cable or adapter. When charging the charger, it will be slightly hot, slightly higher than room temperature is normal, but if the heat is more obvious or even hot, attention should be paid.
During the charging process, the electric energy should be converted into the chemical energy in the charging bank, there is energy transmission and conversion, and heat is normal
