Android 7.0 brings further enhancements to Doze by applying a subset of CPU and network restrictions while the device is unplugged with the screen turned off, but not necessarily stationary, for example, when a handset is traveling in a user’s pocket.<img src="https://developer.android.com/images/android-7.0/doze-diagram-2.png" alt="" class="fr-fic fr-dii fr-draggable " style="" />When a device is on battery power, and the screen has been off for a certain time, the device enters Doze and applies the first subset of restrictions: It shuts off app network access, and defers jobs and syncs. If the device is stationary for a certain time after entering Doze, the system applies the rest of the Doze restrictions to AlarmManager alarms, GPS, and Wi-Fi scans. Regardless of whether some or all Doze restrictions are being applied, the system wakes the device for brief maintenance windows, during which applications are allowed network access and can execute any deferred jobs/syncs.<a href="https://developer.android.com/about/versions/nougat/android-7.0-changes.html" target="_blank">Read official document</a></blockquote>
