Because the internal voltage of the fast charging battery is high, the current is also very large during the fast charging, which will make the temperature inside the battery soar, when the temperature reaches a certain degree, the smart chip will automatically turn off the fast charging function to protect the health of the battery and avoid accidents. Therefore, when your device battery is very low, the fast charge can help you charge quickly, but when the battery is increased, the internal pressure of the battery becomes large, resulting in a rise in temperature, which will make the fast charge automatically shut down, and only normal charging can be used. Therefore, it is recommended to choose fast charging when the power is below 50% to maximize the efficiency of fast charging, and when the power is more than 50%, choose ordinary charging to protect the health of the battery, which can not only extend the battery life, but also avoid the high temperature caused by the fast charging process to the equipment.
1 May be the problem of the fast charge line or the charger itself.
2 Fast charging needs to be carried out at a certain voltage and current. If the current or voltage is unstable due to the damage of the line or charger, the fast charging will fail.
3 You can try to replace a new line or charger, or check whether the mobile phone supports the fast charger, and ensure that the normal connection can use the fast charge function.
Regarding this problem, it may be because the refresh rate of the fast-charging display is very high, and the charging status can be displayed only when charging, and will disappear immediately once the charging is completed or stopped. In addition, some devices may automatically turn off the display screen while charging, which can also result in a short display time for fast-charging displays.
2, change the lock screen style of the phone (with other lock screen styles, the screen will not display the related icon of flash charge when charging;)
3, confirm whether to use the original charger, data cable;
4, the connectivity of the socket will also affect charging, you can replace other sockets to try charging;
5, disconnect the power, restart the phone and put it for a while, and then try to charge it;
6, mobile phone Settings -- system management\/more Settings -- Backup and reset\/restore factory Settings -- restore all Settings;
The system is so set, or in the screensaver state to insert the charger, the charging icon will generally show about ten seconds, ten seconds after the charging image will disappear, you can judge the charging from the upper right corner of the battery status
