Android 6 onward 'Background Running Issues' 

Android has introduced 2 new power-saving features that extend battery life for users by managing how apps behave when a device is not connected to a power source.

The release of Android 6.0 onward has introduced 'Doze' and 'App Standby'. 'Doze' reduces the battery consumption by deferring background CPU and network activity for apps running in the background when the phone has been idle for a long period of time. 'App Standby' defers background network activity for apps with which the user has not recently interacted.

Thus, optimising the performance of the battery. 

'Doze' and 'App Standby' manages the behavior of all apps running on Android 6.0 or higher.

Apps such as, CAT Manager are designed to run in the background as it needs to access the network and to sync with the online portal providing updates and notifications at regular intervals.
