One earbud battery drains faster than the other

This is normal if:

You may notice one earbud discharging faster than the other due to the following normal usage conditions:

• One earbud is primarily used for calls, microphone functions, or touch controls.

• A master–slave configuration is active, where one earbud handles the main connection.

To balance battery usage:

• Use both earbuds together instead of using a single earbud frequently.

• Ensure both earbuds are fully charged before use.

If the battery drain difference is excessive or sudden, please contact customer support for further assistance.
