This mechanism effectively minimizes battery consumption during periods of inactivity, leading to extended standby times. As an example, leaving a phone undisturbed overnight would trigger Doze, preventing unnecessary battery drain from background processes and network synchronization.
-
Impact on Application Behavior
The implementation of Doze necessitated adjustments to application behavior. Applications were no longer able to freely access the network or execute background tasks while the device was in the Doze state. To address this, Android 6.0 introduced “exemptions” or “whitelisting,” allowing specific applications to bypass Doze restrictions. For example, messaging applications often require uninterrupted access to the network to receive incoming messages promptly. However, indiscriminate use of exemptions could negate the benefits of Doze, emphasizing the need for judicious application design.
-
Maintenance Windows
To ensure that important background tasks are not indefinitely deferred, Doze incorporates periodic “maintenance windows.” During these short intervals, the system temporarily exits the deep sleep state, allowing applications to synchronize data, receive push notifications, and perform other essential tasks. The frequency and duration of these maintenance windows are managed by the operating system to strike a balance between battery savings and application responsiveness. This ensured, for instance, that email applications could periodically check for new messages without continuously draining the battery.
-
Integration with App Standby
Complementing Doze is the “App Standby” feature, introduced concurrently with Marshmallow. App Standby analyzes application usage patterns and places infrequently used apps into a restricted state, limiting their access to system resources. This feature works in conjunction with Doze to further optimize battery life on Android 6.0 devices. For example, an application used only once a month would be placed in App Standby, preventing it from consuming background resources when not actively in use, thus extending battery life.
