Why does the Redmi Buds 6 Pro suddenly fail to charge?

The possible reasons for this issue are as follows:
1. The earbuds have not been used for a long time, resulting in power consumption and shutdown;
2. Poor contact between earbuds and charging case or dirty contact points;
3. The charging adapter used is incompatible.
To resolve this issue, please refer to the following solutions:
1. It is recommended that you charge the earbuds for at least 30 minutes to ensure activation;
2. Repeatedly insert and remove the earbuds from the charging case 3 times. If the contact is fine, the LED light will turn on when the earbuds are inserted into the charging case;
3. Use a cotton swab to wipe and clean the charging contacts of the earbuds and charging case.
