Why can't the charging case of the Xiaomi OpenWear Stereo Pro be charged?

If your Xiaomi OpenWear Stereo Pro charging case fails to charge, please consider the following possible causes and solutions:
1. Using unofficial or damaged charging cables and adapters can prevent proper power supply. Always use the original charging cable and the official recommended charger.
2. Low power from the outlet or loose connections can cause the charging case to fail. Try a different power outlet to ensure stable charging.
3. Dust, moisture, or oxidation inside the charging port can block current flow. A loosely inserted cable can also prevent charging. Clean the port with a dry soft cloth or cotton swab and ensure the port is not damaged or loose.
4. Bugs in the firmware can cause abnormal charging status. Make sure the Xiaomi OpenWear Stereo Pro is updated to the latest firmware version.
5. Charging in too hot or too cold environments can prevent the case from charging. Always charge in a room-temperature, ventilated environment.
6. If none of the above solves the problem, contact the after-sales support for repair or replacement.
