Why does my phone get hot when charging with fast charging?

The reason why the phone heats up during fast charging may be due to fast charging technology, poor heat dissipation, high temperature environment, battery aging, etc. Detailed introduction: 1. Fast charging technology. Fast charging technology speeds up the charging speed of the battery by increasing the charging current. This can charge the mobile phone in a short time and is convenient for users. High current input will cause the electric energy inside the battery to be converted into Thermal energy will cause the phone to heat up; 2. Poor heat dissipation. The phone will generate heat during charging. If the heat dissipation design of the phone is poor or the heat dissipation holes are blocked, the heat will not be effectively dissipated, etc.

It is a normal phenomenon for mobile phones to heat up during fast charging, which is mainly caused by the following reasons:

1. Fast charging technology: Fast charging technology speeds up the battery life by increasing the charging current. charging speed. This can charge the mobile phone in a short time and is convenient for users. However, high current input will cause the electrical energy inside the battery to be converted into heat energy, causing the phone to heat up.

2. Poor heat dissipation: The mobile phone will generate heat during the charging process. If the heat dissipation design of the mobile phone is poor or the heat dissipation holes are blocked, the heat will not be effectively dissipated, causing the phone to heat up. Especially when using a mobile phone, such as playing games or performing other energy-intensive tasks at the same time, it is more likely to cause the mobile phone to heat up.

3. High temperature environment: During fast charging, due to the accelerated charging speed of the battery, the chemical reaction inside the battery will also become more active, thus generating more heat. If fast charging is performed in a high-temperature environment, the heat of the phone may be more obvious.

4. Battery aging: As the battery usage time increases, the battery performance will gradually decrease and the internal resistance will increase. During fast charging, the battery's internal resistance causes more energy to be converted into heat, causing the phone to heat up.

Although the mobile phone will generate a certain amount of heat during fast charging, under normal circumstances, the heat generated by the mobile phone will not have much impact on normal use. However, if your phone overheats, it can negatively impact battery life and phone performance. In order to avoid this situation from happening, you can take the following measures:

1. Use the original charger: In order to ensure the quality and compatibility of the charger, it is recommended to use the original charger for charging. Original chargers usually provide the appropriate current and voltage based on the phone's needs to reduce the risk of overheating.

2. Avoid performing high-energy-consuming tasks at the same time: When fast charging, try to avoid performing high-energy-consuming tasks at the same time, such as playing games, shooting videos, etc. This can reduce the load on the mobile phone and reduce the degree of heat generation.

3. Avoid using the phone for a long time: Using the phone for a long time will cause the phone to heat up, especially when charging quickly. To avoid overheating, you can appropriately reduce the use time or use it intermittently.

4. Maintain a ventilated environment: When using a mobile phone, try to maintain a ventilated environment and avoid using the mobile phone on quilts, pillows and other objects. Also, make sure the back of the phone is not covered so that heat can escape better.

5. Do not use inferior chargers: inferior chargers may not be able to provide stable current and voltage, causing the phone to overheat or even be damaged. Therefore, it is recommended to choose a charger from a regular brand and avoid using cheap chargers with unreliable quality.

It should be noted that if the mobile phone generates excessive heat, frequent heat or other abnormal conditions during normal use, there may be a problem with the mobile phone. It is recommended to consult the mobile phone manufacturer or professional technicians in time for maintenance.
