Some heat may be generated during wireless charging. This is normal and does not indicate any issue with the charging case.

It is normal for the FreeClip charging case to heat up during wireless charging as it contains metal sheets that conduct heat. The temperature will drop quickly once charging stops. There is no need to be concerned.

If the charging case heats up significantly during charging, perform the following steps:

1. Check the charging environment: It is recommended that you charge the earphones in a well-ventilated environment with a temperature of 20°C–25°C, for example, on a desk indoors. Avoid charging the earphones in a hot, high-humidity environment.
2. Make sure that you correctly place the charging case to charge it, by referring to Charging instructions and precautions for HUAWEI FreeBuds series earphones.
3. Connect the charger to a standard adapter and cable for charging. If you use a non-HUAWEI wireless charger or a non-certified wireless charger, the charging case may fail to charge properly or may even be damaged.
4. Restore the earphones to their factory settings and try again.

If the issue persists, take your device and proof of purchase to an authorized Huawei Customer Service Center for assistance.
