Some friends of iPhone owners reported on the social platform that the iPhone 14 Pro will get hot when charging. This problem is not a small problem, which troubles many iPhone 14 Pro owners. But you know what? This problem is actually avoidable. As long as we understand several reasons why the phone is hot during charging, we can effectively avoid it. What I brought today is the reason why the iPhone 14pro is hot when charging!

Why is the iPhone 14pro hot when charging? What is the reason for the hot charging of the iPhone 14pro

It is normal for the charger to generate heat when charging the mobile phone, which is related to the current intensity output by the charger and the ambient temperature. With the popularity of smart phones, the requirements for chargers are getting higher and higher. In the era of functional phones, the 500mA charger can no longer meet the user's demand for charging speed. Therefore, we can see that the current of common chargers is above 1A, and many chargers have reached 2A.

In addition to the current increase, the size of the charger is also a problem. For the convenience of carrying, people often prefer smaller chargers. However, the smaller the size, the worse the heat dissipation performance, and the higher the requirements for electronic components. Take the capacitor as an example. When the capacity of high-voltage capacitor remains unchanged, the volume is smaller and smaller, and the withstand voltage and temperature are better. If the withstand voltage is not enough, the capacitor will be broken down, and if the temperature is not enough, the capacitor will burst

In addition, the high temperature of the charger also has a lot to do with the switch tube of the charger. If the switch tube specification is not high, the current will pass through and generate more heat.

The components of the charger that generate a lot of heat are: high-voltage capacitor, switch tube and high-frequency transformer. The temperature of these three components is quite high. It is not difficult to reduce the temperature of these three components. Generally speaking, when the output current is unchanged, the power of high-frequency transformer is relatively large, and the temperature of high-power high-frequency transformer is much smaller. In short, it is necessary to give it extra power, just like a cart pulling small things. Of course, it is easier for the switch tube to dissipate heat, as long as it is equipped with enough heat sinks. However, due to volume limitations, it is impossible to reduce heat generation. Therefore, it is inevitable that the charger will heat up.

Of course, the above only refers to the heating of the genuine charger. If it is a counterfeit charger, it is another matter. The stability of the output voltage of the counterfeit charger itself is not as good as the original charger, which will cause slow charging, serious heating of the charger and other problems. It is strongly not recommended to use fake chargers here! Keep away from danger!

Basically, the reason why the iPhone 14pro gets hot when charging is the above. I would also like to advise you that in addition to the phone components, improper use methods may also cause the phone to get hot when charging. For example, playing games while charging will not only make the phone hot, but also may affect its service life.
