    If you have AirPods connected, this will display their current battery life as well.

  3. The percentage of remaining battery life will be displayed, along with a button labeled Power Reserve. Slide this button to the right if you’d like to enter Power Reserve mode, which conserves your battery by turning off all features with the exception of the current time clock.
