The reasons for the slow charging of Huawei chargers may be as follows:
1. Poor contact between charger and data cable: Please check whether the charger and data cable are plugged in to ensure good contact between the two. If the contact is poor, it may cause the charging speed to slow down.
2. Using non-original data cables: Using non-Huawei original data cables may slow down the charging speed. You are advised to use the data cable recommended by Huawei.
3. Charging interface dirty: If the charging port is blocked by dust, it will cause poor contact, not only the charging speed is slow, but more serious may make the phone unable to charge. Use a needle or toothpick to carefully clean the charging port.
4. Aging mobile phone battery: After the mobile phone battery is used for a long time, its capacity may decrease, resulting in slower charging speed. In this case, you may want to consider replacing your phone battery.
5. System problems: Some system problems may affect the charging speed. It is recommended that you check the battery options in your phone system Settings to see if there are relevant charging Settings, or upgrade your phone system to the latest version.
6. Charger failure: If the above methods can not solve the problem, please check whether the charger is faulty. You can try to use another charger to charge your phone to eliminate the charger problem.
7. Charging mode mismatch: Some Huawei mobile phones support fast charging function, if the charging speed is still slow, it may be because the phone has not entered the fast charging mode. You can view the Huawei Charging icon to check whether the phone is in fast charge mode.
Locate the problem based on the preceding suggestions, and take appropriate measures to resolve the problem. Hope your problem can be solved!
