1. One of the reasons why the mobile phone can't be charged may be the static electricity generated by the charger at work. This static electricity will accumulatemore and more in a dry environment, resulting in that the mobile phone can't be charged. Therefore, we can wipe the charger with a wet towel after charging.

2. The second reason may be the voltage problem of the charger. For some mobile phones, if the charging voltage is wrong, it will also lead to failure to charge.For example, sometimes when charging with a computer linked data cable or using a non original charger, the touch screen will fail. The solution is to use the original charger or a better quality charger as much as possible.

3. In addition, if the mobile phone charger cannot charge the mobile phone normally, check whether it is a data cable problem; And whether it is the dust and other sundries accumulated at the charging port of the mobile phone, which leads to poor contact between the mobile phone interface and the charging line
