9 Disable Background App Refresh
Background App Refresh allows apps to continue running in the background while you use other apps. For instance, the Mail app will run in the background to fetch new emails as they arrive. If an app is consuming a lot of battery, then you should disable Background App Refresh so that it doesn’t run in the background.
- Go to Settings.
- Tap General.
- Tap Background App Refresh.
- Then toggle off the feature completely or on a per app basis.
If there are certain apps that are consuming a high amount of battery in the background, then disable Background App Refresh for those apps only.
