1, it is possible to change a charging cable, charging will be slow.
< br >
2, the charging temperature is too high, the battery temperature will be higher than a certain value, so that the charging current will gradually decrease, so that the charging speed will be slower. The charging speed decreases.
< br >
3, the data cable interface can not be fully plugged into the phone, so fast charging may enter the ordinary charging mode, resulting in slow charging.
< br >
4, working in a dusty environment, the phone is exposed for a long time, resulting in dust into the charging interface. If you often put the phone in your pants pocket, and the charging port faces down, it is also easy to let the charging interface of the phone into dust. After the dust enters the mobile phone, it is easy to block the charging port, resulting in poor charging contact, which will also make the mobile phone charge slowly.

Extended data
Charging the speed of the method:
< br >
1. Turn on flight mode or power saving mode
< br >
Turning your phone on airplane mode can prevent harassment and actually speed up charging; The phone opens the power saving mode, which will limit the background activities of the application, stop synchronous activities, and weaken the visual effect, so that the charging will be relatively faster. Of course, it will be faster to switch off and charge.

2. Don't play with your phone while charging
< br >
When the phone is charging, it is not recommended to play while charging, because it can prevent high temperature or other safety hazards.
< br >
3, regularly clean the dust of the charging interface
< br >
When you find that the phone is charging slowly, you can also use a toothpick, paper clip or card needle into the charging port to clean up, and you can also use a hair dryer to blow on the charging port. In addition, when the phone is placed in the pocket, it is recommended that the charging port face up, so that the phone will not get on the fiber wool or dust in the pocket.

4, choose the right charger
< br >
In addition to the original, you can choose a third-party brand fast charging head that meets the fast charging specifications. On the data line, the length can be maintained at 1m; The thickness of the data line can be judged by the size of the AWG value, the smaller the value, the larger the diameter of the wire.
