You can check it according to:
1. When the wireless charger charges the device, the device first needs to support Huawei private wireless charging or be certified by the Qi standard, otherwise it cannot charge the device.
2. When charging the device with wireless charging, the receiving coil of the device overlaps with the center of the charger coil as far as possible, and the charging efficiency is reduced when the offset is too large, affecting the charging speed.
3. When charging the device, try not to use a phone case containing metal or a phone case with too much thickness, which may cause the charger to detect foreign objects or reduce the charging efficiency, affecting the charging speed.
4. If you continue to use the phone while charging the phone, such as playing games, watching videos, etc., will also affect the charging speed.
