How to remove “app running in the background” notification in Android?

Advancements in the Android operating system brought many new challenges. While Google is doing a great job covering all the aspects and optimizing Android, there are still some areas which need some fixing. Ever since Android Nougat, Google became battery focused. As the system and apps became heavy, they used a lot of battery. Hence, Google introduced Doze Mode to increase system on time (SOT) and standby time. However, apps still kept running in the background and consumed a lot of battery juice. To further optimize the apps usage, a new feature was introduced that would kill or stop apps running in the background.
Though the feature kept the apps from running in the background, it brought the Android System’s annoying notification. As some of the apps would always run in the background, “running in the background”, notification will show up more frequently in the notification panel.
Some notifications we say include “WhatsApp running in the background is using too much battery”. Or the classic Android System’s notification of – 2 apps are running in the background. These notifications are basically from Android System and there is no option to disable it from Settings. However, here is a simple trick which will let you hide or remover the annoying running in the background notification.
