What to do if the Redmi Buds 6 Play cannot be charged?

If the earbuds cannot be charged when placed in the charging case after the battery is depleted, please refer to the following steps to troubleshoot the issue:
1. It is recommended that you charge the charging case for at least 10 minutes to ensure that the earbuds are activated;
2. Repeatedly insert and remove the earbuds from the case 3 times. This action helps reset the connection between the earbuds and the charging case contacts. If the contact is normal, the charging case indicator will light up when the earbuds are inserted into the case, indicating that charging has begun;
3. Use a cotton swab to gently wipe and clean the charging contact copper pillars at the bottom of the earbuds. Dust, dirt, or debris on the contacts can prevent proper charging. Ensuring that these contacts are clean will promote normal contact with the charging case, facilitating efficient charging.
