You can check your Jaybird Vista earbuds battery status and your charging case battery status in a few different ways.
You will hear a battery status notification as soon as the earbuds are taken out of the case and automatically turn on.
During use you will hear battery status notifications when 20% of the battery charge is left, and when the battery is at 10%.
The Jaybird App will indicate your left and right earbud battery status to within 1%.
