Why is the iPhone 13 promax hot when charging
It is normal for a mobile phone to burn when charging, even for a top equipped mobile phone like the iPhone 13 promax. Especially 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 more than 1A, which makes mobile phones more hot. Besides, do you know why the iPhone 13 promax gets hot when charging?
Why is the iPhone 13 promax hot when charging? What is the reason for the hot charging of iPhone 13 promax
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!
Why is the iPhone 13 promax hot when charging? There are many reasons, but they are basically related to the charger. Let's see if it is the above reason.
