Work with the Battery Saver featureīattery Saver is a system-level feature that users can configure in Settings. This can be accomplished by Launching the Settings App to the Background Apps or Battery Usage Details page. If your app has been denied permission to run in the background but requires background activity to complete an action for the user, you can notify the user and point them to the Settings app. In your app, you can use the BackgroundAccessStatus enum value returned by a call to the BackgroundExecutionManager.RequestAccessAsync() method to determine its current background activity permission setting.Īll this is to say that if your app doesn't implement responsible background activity management, the user may deny background permissions to your app altogether, which is not desirable for either party.

When the box is unchecked, the background activity will be disabled. When the box is checked, the app will be allowed to run background tasks at all times. If the user switches to Off, they are presented with a checkbox with which they can manually define the background activity permissions. On desktop devices, the 'Managed by Windows' setting is presented as a toggle switch, set to On by default. Background activity can be set to 'Always allowed,' 'Never allowed,' or 'Managed by Windows,' which means the app's background activity is regulated by the system according to a number of factors. On mobile devices, users will see a list of radio buttons that specify the background task permission setting for that app. For UWP apps on this list, users can select the app to open up controls related to background activity. Here they will see a list of apps and the percentage of battery life that each app has consumed (out of the amount of battery life that has been used since the last charge). On desktop and mobile devices running Windows 10, version 1607 or later, users can view their 'Battery usage by app' in the Battery section of the Settings app.

See Create and register an out-of-process background task for more information. A background task is any program activity that has been registered with the system to run without the app being open. All-day battery life is a desirable feature to every user, but it requires efficiency from all of the software installed on the device, including your own.īackground task behavior is arguably the most important factor in the total energy cost of an app.

On battery-powered devices, power consumption is a critical factor in the user's overall experience with your app. Universal Windows apps should perform consistently well across all device families.
