View App and System Activity information

The App and System Activity section helps you understand what’s using your battery by listing the percentage of battery used by each app and system task.

You might see the following information under an app or system activity, or when you tap an app to view more details. Here’s what they mean:

  • On screen: The app or system activity was open and visible on your screen. A long duration of onscreen time can explain higher battery usage compared to previous days.

  • Background: A long duration of background time can explain higher battery usage compared to previous days. Background activities include directions, playing music, syncing photos, fetching mail, and more.

  • Cellular coverage: The app was used in a low signal environment, which used more battery.

  • Notifications: The app or system activity woke your device and used battery to check for new information. You can manage an app’s notification settings to reduce how often this happens.

👁 The Battery Usage screen in Settings on iPhone displays the “App and System Activity Usage” list, breaking down battery consumption by app. Each app is listed with its corresponding percentage of battery usage and its on-screen or background activity time.
