The setting is called Sleeping Apps. You will find it at Settings > Battery > Background usage limits. Turn it on, and One UI starts tracking apps you do not use often and puts them to sleep.
It keeps track of apps you don’t use often and puts them to sleep, essentially stopping these apps from running in the background constantly and consuming resources.
One MakeUseOf writer reported that this ended up improving his phone’s battery by more than 30%, without making any compromises.
I tested it on my Galaxy S26 Ultra running One UI 8.5. Same result. Here is exactly how to set it up and which apps to leave alone.
I am Ameer Hamza, and at Global Tech Press, I test every Samsung battery setting before recommending it. This one is the real deal.
How Sleeping Apps and Deep Sleep Actually Work
Samsung’s One UI has two tiers of background restriction.
Regular sleep restricts background activity significantly. Deep Sleep prevents apps from running in the background entirely. Deep Sleep works perfectly for apps you need installed but rarely use.
According to Samsung’s own developer documentation, background applications that have not been used for about 3 days and are causing poor system health will go into sleeping mode. A bucket restriction applies to any sleeping applications, and features such as Job, Alarm, and Foreground service are restricted.
That means an app in Sleep mode can still occasionally check for updates, but it cannot freely run in the background. An app in Deep Sleep is completely frozen until you manually open it.

How to Set It Up Properly
Here is the step by step path:
Open Settings. Tap Battery. Tap Background usage limits. You will see three lists: Sleeping apps, Deep sleeping apps, and Never sleeping apps.
Head to Settings > Battery > Background usage limits > Sleeping apps or Deep sleeping apps. Tap the plus icon at the top, and start adding apps. If you want to remove any app from the list, tap the three dot icon in the top right corner and choose Remove.
The system works automatically by default. But you can also take manual control and add specific apps to whichever list makes sense for your usage.
The key benefit of this Samsung battery setting is that it doesn’t force you to make any compromises for battery life, like lowering the screen refresh rate, reducing the screen brightness, or keeping the power saving mode on.

Which Apps to Never Put to Sleep
This is where most people make mistakes.
Don’t put every app to sleep. Cloud storage apps need background access for automatic backups. Messaging apps require it for timely notifications. Work collaboration tools become useless if they can’t alert you to updates.
Add apps like WhatsApp, Telegram, OneDrive, Google Drive, and Samsung Health to the Never sleeping apps list. These apps are useless if they cannot send you notifications or sync data in the background.
If you want to make sure an app never gets deep slept, go to Settings > Battery > Background usage limits > Never sleeping apps, then add the app there manually.
Everything else, those 150+ apps you installed but barely touch, should either be in Sleep or Deep Sleep.
Deep Sleep: The Nuclear Option
Deep Sleep is the most aggressive Samsung battery setting available.
The problem with adding apps to the Deep Sleeping list is that they are delinked from Google Play Store and would not receive any updates until the app is launched again. Deep Sleeping Apps setting is likely the more aggressive setting to prevent apps from running in the background.
Use Deep Sleep for apps like airline check in apps, old games, loyalty card apps, and anything you keep installed “just in case” but open less than once a month. These apps do not need to run in the background at all.
If you are on a Galaxy S26 and want to protect your battery health long term, we also covered the 80% battery protection setting most S26 owners get wrong.
The Bottom Line
This is not a flashy feature. Samsung does not advertise it on stage during Unpacked events. But the Sleeping Apps feature inside One UI’s background usage limits is the single most effective Samsung battery setting you can change today.
No reduced brightness. No lower refresh rate. No power saving mode. Just smarter resource management that stops apps you barely use from draining your battery all day.
Go to Settings > Battery > Background usage limits right now. Spend five minutes adding the right apps to the right lists. Your battery will thank you by dinner time.
