The charger responds to charging, but the battery level does not increase or decrease. In most cases, this problem occurs because the mobile phone is operating the program during charging or the mobile phone system has a high power consumption problem. As a result, the input current of the charger is insufficient to offset the battery level. Therefore, if the battery level does not increase, the charger may become increasingly charged. In addition, this problem may also occur when a mobile phone is connected to a computer, charging, or charger fault occurs. The output current of the USB interface on the computer is very low and unstable. If the output current is too low, the power consumption of the mobile phone cannot be offset, so the power consumption is not increased.
1. Do not use the mobile phone while being charged, and observe whether the mobile phone can be charged properly when it is not used.
2. It is recommended that a standard charger be used to charge the mobile phone. Do not use a USB interface of a computer or a device with a small output current to charge the mobile phone.
3. If a standard charger is used to charge the battery when the mobile phone is powered on, the battery level does not increase. It is recommended that you power off the mobile phone and charge it. If the mobile phone is powered off and charged properly, the power consumption may be fast caused by the software. It is recommended that you upgrade the system to the latest version and uninstall the high-power-consumption app on the mobile phone. Before charging, clean up the app on the mobile phone, or restore the mobile phone to factory default.
4. If the charger still cannot be powered off and charged properly, it may be a charger fault. It is recommended that you replace the charger. After the above operations, if the problem still exists, back up the data and carry the purchase invoice to the after-sales service office for repair.
