The mobile phone is not charged or charged less, generally because the current input of the charging device is not enough to offset the electricity consumed by the mobile phone itself. If you use a Huawei mobile phone, perform the following steps to rectify the fault:
First, please confirm whether you use the original charger, data cable to charge
When using a non-original charger, data cable or mobile phone to connect to the computer USB charging, it may be due to the small output current, the charging amount can not offset the power consumption of the mobile phone, resulting in no charge or less charge.
You are advised to use Huawei standard charger and data cable to charge the mobile phone. Do not use the USB port to charge the mobile phone.
Second, please confirm whether there are foreign objects in the data cable interface or mobile phone charging jack, or the interface is loose and has poor contact
There is a foreign body in the interface or the interface is loose, which makes the phone and the data cable have poor contact, the output current of the charger becomes smaller, and the charging amount cannot offset the power consumption of the phone, resulting in no charging or less charging.
Before charging the phone, ensure that the charging port is clean and the port connection is stable.
Please confirm whether the phone is running a high power consumption program when charging
Third, the mobile phone running high power consumption programs (such as taking photos, videos, games, etc.) when charging is easy to lead to the charger input current is not enough to offset the power consumption of the mobile phone itself. In addition, when the ambient temperature is high, running a high-power program while charging can easily cause the temperature of the phone to overheat. Huawei mobile phone has a special overheat protection design. When the temperature of the mobile phone is high, the charging current will decrease. In this case, it is more likely to fail to charge or charge less.
