Samsung Galaxy phones have a feature that allows users to put apps to sleep to save battery life. This prevents them from running in the background and wasting battery power. While sleeping apps may still run in the background, notifications and updates may be delayed. Deep sleeping apps, on the other hand, will never run in the background and only work when manually opened by the user. Users can also choose to select never sleeping apps that will never turn off or sleep and are always accessible. This feature is ideal for essential and frequently used apps.

Waking sleeping apps on the Galaxy Note 9 can be done by tapping the app icon
To put an app to sleep on a Samsung phone, you can press and hold the app icon on your home screen or in the application tray. From there, you can choose to sleep or disable the app. Sleeping apps will not use any battery life and will be temporarily shut down.
Samsung divides background limits into three categories: sleeping apps, deep sleeping apps, and never sleeping apps. Sleeping apps will run in the background but only occasionally, meaning notifications and updates may be delayed or irregular. Deep sleeping apps will never run in the background and will only work when you open them. Never sleeping apps can always run in the background and are not restricted by battery usage.
You can add or remove apps from these categories by going to Settings > Battery and device care > Battery > Background usage limits. Tap the category you want, then tap the + sign, select your desired app(s), and tap Add. To remove an app, tap More options (the three vertical dots), tap Remove apps, select the app(s) you want to delete, and tap Remove.
It is important to note that system apps such as Phone, Camera, Clock, Messages, and Bixby cannot be put to sleep as they are integral to the phone's operating system. Additionally, sleeping apps may not receive updates or send you notifications until you wake them up.

If you want to wake sleeping apps on your Galaxy Note 9, you can do so by going to Settings > Battery and device care > Battery > Background usage limits. Here's a step-by-step guide:
- Go to Settings: This is where you'll be able to access and adjust your phone's various settings and options.

- Tap on Battery: This will allow you to view and adjust settings related to your device's battery usage and performance.
- Tap on Background usage limits: This section lets you control how your apps behave when they're running in the background, including the ability to put them to sleep or allow them to run freely.
- Find the Sleeping apps or Deep sleeping apps option: Here, you'll see a list of apps that are currently sleeping or set to deep sleep. These apps may have restricted functionality and may not run in the background.
- To wake an app, tap on the three vertical dots or the More options icon: This will open a menu that allows you to edit and manage your sleeping apps.

Toggle off 'Put unused apps to sleep' in the Background usage limits menu
To toggle off 'Put unused apps to sleep' in the Background usage limits menu on your Galaxy Note 9, follow these steps:
- Navigate to and open the Settings menu on your device.
- In the Settings menu, locate and tap on "Battery and device care". This will open a menu that allows you to manage your device's battery usage and performance.
- Within the "Battery and device care" menu, find and tap on "Battery". This will provide you with options to optimize your device's battery usage.
- Under the "Battery" menu, look for "Background usage limits". This setting allows you to control how apps behave when they are not actively in use.
- In the "Background usage limits" section, you will find the option "Put unused apps to sleep". This is the setting that automatically puts apps to sleep if they haven't been used for a while.
- To disable this setting, simply toggle the switch next to "Put unused apps to sleep" to the off position.
By disabling this setting, you are preventing your device from automatically putting unused apps to sleep. This means that your apps will continue to run in the background, potentially impacting battery life, but ensuring that they remain active and receive updates or notifications.
It is important to note that managing background app behaviour can be a delicate balance between optimizing battery life and ensuring app functionality. While disabling "Put unused apps to sleep" keeps your apps active, it may also result in increased battery drain. Additionally, some apps may still enter a sleep state if they are not specifically configured to remain active.
