1. Check whether the original charger is used, the general charging time is 6-8 hours, and test after full charge

2. Check whether the battery is aging or damaged and cannot store power, if it is damaged, it needs to be replaced with a new battery

3. The use environment and method will affect the battery life, for example, using it in a low temperature environment will lead to a decrease in battery output power and actual usable capacity, shortening the battery life, and using it in the case of high volume or complex audio processing, the battery consumption will also be accelerated

4. If you exclude the usage method and environmental factors, the replacement battery still does not store power, or the battery life is poor, it may be an internal hardware failure, please contact the official after-sales inspection and repair
