9 Save Power
If your Apple Watch is low on battery — or you just won’t need anything besides the time for awhile — you can save power with the “Power Reserve” option. The watch will automatically enter this state when the battery gets low. But you can also access it manually.
- Swipe up on your watch face to access Control Center.
- Tap the battery percentage and then slide the Reserve Power slider to the right.
- Tap “Proceed.” Now your watch will only display the current time.
- To exit press and hold the side button.
