Property Value
Type: Microsoft.Phone.Shell..::.IdleDetectionMode
Type: IdleDetectionMode.
Remarks
When user idle detection is enabled, the operating system will go into a low power usage state when the user is idle. Disabling this property requests that the operating system not perform this service. Use this property to disable user idle detection if your application needs to continue running even when the user is not physically interacting with the screen or hardware buttons. Example scenarios include turn-by-turn navigation applications and games that use the accelerometer for input.
This feature should be used with caution. Applications that disable user idle detection will continue to run and consume battery power when the user is not using the phone. It is recommended that applications that disable user idle detection implement their own form of idle detection and enable UserIdleDetectionMode when appropriate. For example, an accelerometer-based game could enable user idle detection if the accelerometer shows no activity for a period of time.
In the current release, the operating system considers the user to be idle when they have not touched the screen or the hardware buttons within the device lock timeout window, specified in the device’s Settings page. The conditions for detecting user idle status may change in future releases. For more information about using this feature, see Idle detection for Windows Phone 8.
