Samsung How to Set up App Power Management

We can put individual apps on the Samsung device into standby (Sleeping apps), which means that they will no longer run in the background. So they will no longer be updated or send notifications until we call them up again.

If the automatic power management of apps is activated, some unused apps are automatically put into standby (deep sleeping apps), which causes them to receive no or only delayed updates or send notifications; this can be explicitly prevented under the menu item "Apps that won´t be put to sleep", which means that they are no longer put into standby.
