Before talking about this matter, let's first understand the principle of the charger heating, in fact, the charger is very hot components: high-voltage capacitor, switching tube, high-frequency transformer, these three components are quite high temperature. It is not difficult to reduce the temperature of these three components, in general, in the case of constant output current, the power of the high-frequency transformer is relatively large, and the temperature of the high-power high-frequency transformer is much smaller. Simply put, it is to give it extra power, just like a big car pulling small things as effortlessly. Of course, the switch tube heat dissipation is easier, as long as it is equipped with enough heat sinks. However, due to volume limitations, it is not possible to reduce the heat generated. Therefore, it is inevitable that the charger heats up.

Understanding the principle, we can easily understand why the current charger will heat up:

1, first of all, this is related to the current intensity of the charger output and the ambient temperature. With the popularity of smart phones, now the charger requirements are getting higher and higher, the 500ma charger in the era of functional machines can no longer meet the needs of users for charging speed, the emergence of the fast charge we said before, in fact, is the inevitable history, so we see that the current of the common charger is above 2A.

2, in addition to the current increase, the volume of the charger is also a key factor, in order to be easy to carry, we often like smaller chargers, manufacturers are also developing towards small and fine. However, the volume is smaller, the heat dissipation performance will be worse, and the requirements for electronic components are higher. Take capacitors, high voltage capacitors in the case of maintaining the same capacity, the volume is getting smaller and smaller, and in terms of voltage and temperature is better, but not enough voltage will breakdown the capacitor, not enough temperature will explode the capacitor.

3, in addition, the high temperature of the charger also has a great relationship with the switch tube of the charger, if the switch tube specifications are not high, then the current passes through, the heat will be more.

Heat caused by mismatch between mobile phone and charger.
3. The mobile phone is used while charging, or the background running program is large, resulting in large current and high temperature.
4, the mobile phone motherboard has leakage.
5, the charging interface or line has dirty things, there is a slight short circuit.
6, the phone battery is bad.
7. The charger is broken.
