Background App Refresh
Just like on an iPhone, many watchOS apps use Background App Refresh to keep their feeds or other features updated in the background. But this can put a toll on your Apple Watch’s battery life. And for users with cellular data plans, it can also eat up some of your monthly allowance.
You can disable Background App Refresh entirely, but we’d recommend tailoring it on a per-app basis.
- Just head to the Watch app on your iPhone
- Select General and then Background App Refresh.
Consider turning off the toggle for apps that you don’t need to be updated in the background.
