Why Use Background Refresh?
Background Refresh works great if you use specific apps on a regular basis. However, it drains battery life, as apps run in the background long enough to download the most current data. If you’re concerned about battery life, turn off the Background App Refresh feature for some or all apps.
This feature is all about convenience, but you probably don’t need every app to refresh in the background. It may make sense for your Gmail app to have messages ready for you when you open it, and if you’re a news fan, you’ll want CNN to be current when you open your iPad.
How to Choose the Background App Refresh Setting for Apps
By default, all apps are activated in the Background App Refresh settings. To change that, follow these steps:
On the iPad Home screen, tap the Settings app to open it. Scroll down the left menu and choose General. Select Background App Refresh. To turn off the Background App Refresh feature completely, toggle the Background App Refresh switch to the Off position (white). To allow some apps to refresh and not others, turn the toggle switch next to the corresponding app to the On (green) or Off (white) position.
