What should I do if the earbud does not charge fully?

If your earbud is not fully charging, please follow the below steps.
1. First charge the earbud continuously for more than 4 hours, and check if the problem has resolved.
2. Use a different standard adapter and cable for charging.
3. Charge the earbuds and charging case in an environment where the temperature is between 0°C and 45°C for optimum charging. If the temperature is too low or too high, it may be difficult to charge the earbuds and charging case
