Can you explain the concept of App Standby Buckets and their role in managing battery consumption and device resources?

App Standby Buckets is a mechanism in Android that helps manage device power consumption and resources by classifying applications into categories based on their activity and user usage.

Apps are distributed into "buckets," such as Active, Working Set, Frequent, Rare, and Never. The lower the app's activity, the more aggressive restrictions are placed on its background activity, network requests, and tasks.

This allows the system to save battery life by limiting resources for rarely used apps, without interfering with actively used ones. For example, an app that the user hasn't opened for a long time will fall into the Rare or Never bucket, and its background tasks will be restricted.

Thus, App Standby Buckets help optimize battery and system resource usage, improving overall device performance and battery life without recharge.
