When Background App Refresh is turned for a specific app, that app has permission to download new information even when it's not open on your iPhone.
Why Should I Turn Off Background App Refresh?
Leaving Background App Refresh on for many apps can significantly drain your iPhone's battery life because the apps will use your connection to Wi-Fi or data network to constantly download new data or information.
I recommend going through your apps one-by-one and determining which ones you want to allow to download new content even when you're not currently using it.
How Do I Turn Off Background App Refresh?
- Open the Settings app.
- Tap General.
- Tap Background App Refresh.
- Tap the switch next to the apps that you want to turn off Background App Refresh on. You'll know Background App Refresh is off on a particular app when its switch is gray and positioned to the left.
