Short battery life

If the battery charge level drains at a faster rate than expected, try the following:

Music playback at full volume will significantly reduce the battery life.

Battery life depends on what type of music you’re playing and at what volume. Use of the speaker at extreme volumes will reduce its playback time. Playback time may be as little as a few hours if the speaker is used continuously at a high volume level while streaming audio over Bluetooth. High intensity, heavy rock music, or music with a lot of bass will consume more power at a high volume level.

To increase the playback time, reduce the volume level.

Check for and install any available product updates.

On a computer, visit btu.bose.com and follow the instructions to ensure your product has the latest features and enhancements. See Updating the software or firmware of your product.

Verify that the battery LED status being indicated.

The battery status indicator can vary depending on whether the system is plugged in, operating on battery power, or checking battery status. For more information, see Understanding LED indicator status lights and information.

Determine if the battery has been fully charged.

For the maximum expected battery life, be sure the battery is fully charged. For more info see, Checking the remaining battery charge.

Be sure the unit is off while not in use.

Leaving the unit on when not in use will drain the battery. However, it will shut off if the system does not detect a Bluetooth signal for 20 minutes*. We recommend turning the system off manually to prevent the battery from draining.
This setting is adjustable within the app. For more info, see Enabling or disabling Auto-Off Mode.
