After some time, the method schedules maintenance windows significantly less and less usually, helping to reduce battery usage in conditions of lengthier-term inactivity when the device is not linked to a charger. When the consumer wakes the device by moving it, turning on the display, or connecting a charger, the program exits Doze and all applications return to typical exercise. Doze limitations
Application only demands to connect with a peripheral machine periodically to sync, or only needs to connect with units, for instance wireless headphones, linked via regular Bluetooth profiles.

No, can't use FCM because of technological dependency on Yet another messaging service or Doze and App Standby split the core function on the application.
Firebase Cloud Messaging (FCM) is usually a cloud-to-device service that lets you support actual-time downstream messaging amongst backend services and apps on Android gadgets. FCM provides a single, persistent relationship to your cloud; all apps needing authentic-time messaging can share this relationship. This shared link appreciably optimizes battery intake by making it unnecessary for many apps to take care of their very own, independent persistent connections, which may deplete the battery promptly. Due to this, if your app requires messaging integration by using a backend service, we strongly advise that you just use FCM if at all possible, instead of retaining your own personal persistent network connection. FCM is optimized to operate with Doze and Application Standby idle modes by means of significant-priority FCM messages. FCM substantial-priority messages Enable you to reliably wake your app to access the community, even though the user’s product is in Doze or even the application is in App Standby manner.

The following limitations utilize to the apps even though in Doze: Network accessibility is suspended. The process ignores wake locks. Regular AlarmManager alarms (including setExact() and setWindow()) are deferred to the following maintenance window. If you should established alarms that hearth although in Doze, use setAndAllowWhileIdle() or setExactAndAllowWhileIdle().
