6 Adjust Background Refreshes
Like on iOS, many apps on the Apple Watch refresh in the background. That comes them packed with up-to-date information, but it can also drain your battery life. You can selectively turn off background refreshing to save battery.
- Open the iOS Watch app.
- Tap General.
- Tap Background App Refresh.
- Turn Background App Refresh off completely with the top toggle, or choose apps to turn off individually.
This also goes for complications, many of which similarly refresh in the background. You may want to go through and weed out the complications that you don’t use very often. Just long press on the watch face and get rid of the unused complications.
