Many apps these days are location aware and are able to refresh themselves in the background. It’s how apps like Facebook can refresh that little red icon badge on your home screen without you having to launch the app.
All that background activity, though, can take its toll on your battery life. Luckily, Apple has included a way to turn this off for specific apps, or altogether.
Launch your Settings app with a tap, and then tap General. Once there, tap on Background App Refresh, just below Usage.
You’ll see a toggle switch at the top which you can tap to turn OFF Background Refresh altogether. If you’re not interested in any apps refreshing in the background, you can take care of that here.
Otherwise, swipe down through the list of apps on your iOS device and toggle the ones you don’t want refreshing in the background to OFF. There’s a surprisingly large number of apps in my Background Refresh list, so it might not hurt for you to check it out.
If you have apps in this list with a little blue arrow next to it, you’ll know that app uses your Location data in the background as well as just updating any network content.
While the amount of battery savings you’ll see will vary with the number of apps you have actively refreshing in the background, there’s bound to be some little bit of benefit to limiting the number of apps that do this on your device.
