If your phone cannot use wireless reverse charging, please follow these steps:
1. Check whether the wireless reverse charging switch is enabled
The phone Settings path is as follows: Settings > Battery, turn on the wireless reverse charge switch.
2. Please confirm whether the charging phone battery is above 20%
If the battery power of the phone is less than 20%, please use the charger to charge the phone first, and then wireless reverse charging after the battery power is higher than 20%. When the battery of the phone itself is less than 20%, the phone will automatically turn off the external wireless reverse charging to ensure the normal work of the phone itself and a good charging experience.
