As android-12 introduces a new Restricted standby mode. as per android doc, it says the app goes to restricted mode based on app behavior + app usage
The system considers your app's behavior, in addition to usage patterns, to decide whether to place your app in the restricted bucket. Your app is less likely to be placed in the restricted bucket if your app uses system resources more responsibly.
Q. What kind of app behavior puts an app into a restricted bucket? Any Example?
