Normally, the earbuds can be used for around 4 hours in ANC mode and 7 hours in Normal mode at 50% volume, but playtime may vary slightly based on the music content and volume. If you use the earbuds to make/receive calls, playtime will be shorter as it consumes more power than playing music.

To fix this issue, please try the following:

1. Use a dry cloth/cotton swab with rubbing alcohol to clean the charging pins in the charging case and on the earbuds to ensure a better connection. Ensure the ear tips are not blocking the charging connectors and fully charge your earbuds.

2. Turn off the dual connections and 3D surround sound.

3. Test the battery when only playing music.

ANC is turned on by default. If you want to test the playtime in Normal mode, switch to Normal mode first.
