Possible issues with power:

1. The earbuds aren't charging.

2. The earbuds are still connected to my device even after returning to the case and closing the lid.

3. The earbuds aren't powering on when taken out of the case.

Steps to fix:

1. Ensure the ear tips do not obstruct the charging pins on the earbuds or in the charging case. Verify the earbuds are connected to the charging case. Place the left and right earbuds into the case separately. If the indicator lights on the charging case turn on for 5 seconds and then turn off, this indicates a successful connection.

2. Use a dry cloth or a cotton swab with rubbing alcohol to clean the charging pins on both the earbuds and the case.

3. Use different charging cables and wall chargers to charge the charging case, and ensure the case has sufficient power. The case cannot charge the earbuds when its battery level is below 5%.

If your earbuds haven't been used for a long time, charge them for at least 2 hours before use.
