Why encounter charging failures or charging interruptions when using the Xiaomi 17 Ultra to wirelessly charge other devices?

If charging fails or is interrupted when using the Xiaomi 17 Ultra for reverse wireless charging, please refer to the following suggestions:
1. The Xiaomi 17 Ultra supports reverse wireless charging for devices that comply with the Qi wireless charging protocol. Please confirm that the device being charged supports the Qi standard.
2. Make sure the charging coils of both devices are properly aligned. The device being charged (such as earphones or a watch) should be placed firmly against the center area on the back of the Xiaomi 17 Ultra to ensure stable power transmission.
3. Check that there are no metallic objects, magnetic accessories, or thick protective cases between the two devices, as these can interfere with wireless charging.
