Why does my mobile phone get hot while charging?

The reasons why mobile phones become hot during charging include the quality of the charging cable and charger, application operations when using the phone, battery problems, ambient temperature, the operation of software and applications, etc. Detailed introduction: 1. The quality of charging cables and chargers is a major cause of heat in mobile phones. Low-quality charging cables and chargers may cause excessive or unstable current, thereby generating excessive heat. It is recommended to purchase genuine chargers. Adapter and charging cable to ensure its quality and stability; 2. Charging when using a mobile phone will also cause heat, and when using the mobile phone for high-intensity applications, such as games, video playback, etc.

It is a common phenomenon for mobile phones to become hot while charging, but the specific reasons may vary depending on various factors. Below I'll detail some common causes and solutions.

First of all, the quality of the charging cable and charger is a major reason why mobile phones heat up. Low-quality charging cables and chargers can cause excessive or unstable current flow, which can generate excessive heat. Therefore, it is recommended to purchase genuine chargers and charging cables to ensure their quality and stability.

Secondly, charging when using a mobile phone can also cause heat. When we use our phones for high-intensity applications, such as gaming, video playback, or using a large amount of network data traffic, the phones will require more energy to support these operations, thus causing heat. At this time, you can choose to reduce the charging time when using the mobile phone, and then recharge the mobile phone after use.

Third, the heat generated on the back of the phone during charging is due to the heat generated by the battery charging. When charging, the battery will receive current and convert it into energy, while also generating a certain amount of heat. If the back of the phone is too hot, it may be because the charger outputs too much current or there is a problem with the phone battery. At this time, you should replace the appropriate charger and consider replacing the mobile phone battery.

In addition, the heat generated by the phone during charging may also be related to the ambient temperature. When charging in a high-temperature environment, the phone will heat up even more, because high temperatures will cause the battery temperature to rise. Therefore, try to avoid exposing your phone to high temperatures when charging, such as directly exposing it to the sun or placing it near a heat source.

Finally, the operation of some software and applications may also cause the phone to become hot while charging. Some apps continue to run in the background, using up your phone's processing power and generating heat. You can reduce heating issues by closing apps running in the background or uninstalling unnecessary apps.

To sum up, there are many reasons for the heat of mobile phone charging, including the quality of the charging cable and charger, application operations when using the mobile phone, battery problems, ambient temperature, etc. The main ways to solve this problem include purchasing high-quality chargers and charging cables, reducing charging when using mobile phones, replacing suitable chargers and mobile phone batteries, avoiding exposing mobile phones to high temperatures, closing applications running in the background, etc. If the problem persists, it is recommended to consult a professional technician.
