The fast and slow charging speed of the Honor 7x charger depends on many factors. First of all, the quality and power of the charger itself will have an impact on the charging speed.
Secondly, the charging speed can be affected by replacing a different charging cable or using a different charging plug.
In addition, the state of the mobile phone battery will also affect the charging speed, such as the aging degree of the battery or the temperature has a certain impact on the charging speed. Therefore, if the charging speed is different, you can try to exclude the above factors and choose the appropriate charging method to obtain a faster charging speed.
It may be that the phone and the charger are not in good contact, or the phone has not had time to display the fast charge icon when it has just charged. It is recommended to reinsert the phone charger to ensure good contact, and check that the charger and the phone port are free of dust and foreign bodies to ensure that the charger is intact.
