Please try the below:
1. Check whether the charger is working properly
Connect the charger to other devices and check whether the charger is charging other devices properly. If not, it means the charger is defective and needs replacing.
Please note: Some chargers may have compatibility issues. We recommend using a mainstream charger.
2. If the charger isn't defective, please:
1) Replace the cable to check if it can be fixed.
2) Check whether there is any foreign matter in the charging port of the phone. If so, clean it with a dry brush or other small tools.
3) Please ensure that the ambient temperature is suitable during the charging process. If the temperature is too high, it will trigger the high-temperature protection and stop charging.
If the issue persists, contact our Customer Support for further assistance.
