Check battery level Fitbit Versa 2
Swipe down from the top of the screen. Wait 2 seconds for the control center to
disappear. The battery level icon is in the top left.
If your watch’s battery is low (less than 24 hours remaining), a red battery indicator
appears on the clock face. If your watch’s battery is critically low (less than 4 hours
remaining), the battery indicator flashes.
Wi-Fi won’t work on Versa 2 when the battery is 25% or less, and you’ll be unable to update your device.
