You can check your FREEDOM 2 battery status in a couple of ways.
When FREEDOM 2 are on and not playing music, pressing “Volume +” or “Volume -” will announce the battery level. The LED will indicate a single green flash for more than 10% battery remaining and a single red flash when below 10%.
Your FREEDOM 2, phone and the Jaybird App will also indicate battery status. Please be aware the voice notification on the FREEDOM 2 will round the battery level to the closest 20% and the Jaybird App will give the FREEDOM 2 battery level to within 1%.
