Many smartphones have a feature that automatically puts unused apps to sleep in the background to save battery life. This can be frustrating for users who want to receive timely notifications from apps or who want to be able to quickly switch between apps without having to reopen them. Some Android phones allow users to prevent apps from sleeping in the background by configuring the settings for individual apps, while Samsung phones refer to this feature as Never sleeping apps. This feature is particularly useful for apps that are critical to have running in the background, such as alarm clocks or blue light filter apps.

What You'll Learn

Never sleeping apps on Samsung devices
Samsung devices have a feature called "Sleeping apps" that allows you to manage your apps' background activity and improve battery life. Sleeping apps are apps that run in the background on your device even when not in use.
The "Never sleeping apps" setting on Samsung devices allows you to specify apps that will never turn off or sleep in the background, ensuring that they are always active and accessible. This can be useful for apps that you want to receive instant notifications or updates from, such as messaging or email apps. To add an app to the "Never sleeping apps" list, go to your device's Settings, tap on 'Battery and device care', and then tap on 'Never sleeping apps'. From there, you can tap the "+" sign, select the app you want to add, and then tap "Add".
It's important to note that while keeping certain apps active in the background can be convenient, it may also impact your device's battery life. Samsung devices have other power-saving features, such as "Deep sleeping apps" and "Put unused apps to sleep," which can help conserve battery by restricting background activity for apps that you rarely use. For example, if you rarely use the Calculator app, setting it to "Deep sleep" will prevent it from draining battery life.
Additionally, Samsung's "App power monitor" feature, introduced with the Galaxy S8, allows you to manage background app activity individually for each app. To do this, go to Settings > Device maintenance > Battery, where you can whitelist specific apps to exclude them from App power monitor's restrictions.
By customizing your Samsung device's sleeping app settings, you can strike a balance between keeping important apps active and managing battery life by restricting background activity for less frequently used apps.
