Use Samsung’s built-in Background usage limits settings to manage apps that run in the background. Add an app to Sleeping apps for a lighter restriction, or to Deep sleeping apps if it should run only when you open it. These limits can delay notifications and updates, so keep apps you rely on for timely background activity out of deep sleep.

Open Background usage limits

On many Galaxy phones, go to Settings > Battery and device care > Battery > Background usage limits. On some newer models, the path is Settings > Battery > Background usage limits. Samsung says menu names and locations can vary by model, software version, and region. If you do not see the first path, check the Battery page in Settings; on older software, Battery may be under Battery and device care. Samsung US support and Samsung Canada support describe these paths.

Choose the right background restriction

Setting What it does What to expect
Put unused apps to sleep Automatically puts apps to sleep after they have not been used for a while. Useful for routine management of apps you rarely open.
Sleeping apps Lists apps that are sleeping; they may still run in the background when needed. Less restrictive than deep sleep. Samsung Australia warns that apps may run intermittently and updates or notifications may be delayed.
Deep sleeping apps Stops apps from running in the background; they work only when opened manually. Choose this only when background activity and timely notifications are not important.
Never sleeping apps or Never auto sleeping apps Exempts selected apps from sleep management. Use selectively: exempted apps can remain available in the background and may use more battery.

These definitions come from Samsung US support; the notification and update caveat for sleeping apps is described by Samsung Australia. The exact exemption-list wording differs across Samsung materials, so use the label shown on your phone.

Add or remove apps from a list

  1. Open Settings and navigate to Background usage limits using the path available on your phone.
  2. Tap Sleeping apps, Deep sleeping apps, or the relevant list.
  3. Tap the plus or add control, select the app or apps, then tap Add.
  4. To undo the restriction, open the same list and use its edit or remove control. Its placement and wording depend on the software version.

Samsung’s support pages explain the add-and-remove process, though the control labels can differ by version: Samsung US and Samsung Canada.

Which apps should you keep out of deep sleep?

Consider how you use each app rather than applying deep sleep across the board. If you need an app to deliver timely alerts or perform background updates, avoid deep sleep; Samsung says a deep-sleeping app works only when opened manually. Sleeping apps are a lighter option, but Samsung warns notifications and updates may still be delayed. Use the never-sleeping exemption only for apps that genuinely need background availability.

Samsung Developer documentation describes automatic sleeping and deep-sleeping management based on usage patterns and background battery consumption. It also notes that, since One UI 6 with Android 14, foreground services for apps targeting Android 14 are guaranteed to work as intended when those apps follow the updated foreground-service API policy. That is a qualified statement about conforming apps, not a promise that restricted apps will deliver timely notifications. Samsung Developer: Application management.

Will this save a specific amount of battery?

Samsung’s cited support material does not quantify a guaranteed battery-life improvement for putting apps to sleep. The practical effect depends on app behavior and which restrictions you choose; treat these controls as a way to limit unwanted background activity, not as a promise of a fixed battery gain.
