Step by step

Open Battery
Open Settings and tap Battery.

Tap Background usage limits
It is below Power saving on the Battery page.

Leave Put unused apps to sleep on
With this switch on, apps you have not used for a while are put to sleep by themselves.

Open Deep sleeping apps
Deep sleeping apps never run in the background. They only work while you have them open. Sleeping apps is the milder list: they run in the background only now and then.

Tap + to add an app
Tick the apps you want to stop and confirm. Apps the phone added by itself are listed under Automatically added.

Protect the apps that must keep working
Back on Background usage limits, tap Never auto sleeping apps and add apps such as WhatsApp, your alarm or a fitness tracker. A sleeping messenger may deliver messages late.
About this guide
Apps you rarely open can keep running in the background, using battery and data. One UI can freeze them until you open them again. On our phone, six apps had already been put into deep sleep automatically.
The screenshots are from a Samsung Galaxy A57 5G with One UI 8.5 and Android 16. Other Galaxy phones on One UI 8 use the same menus; on older One UI versions a few names and positions differ.
Good to know
If notifications from an app stop arriving, check that it is not in Deep sleeping apps. Open it once and remove it from the list.
Deep sleep does not uninstall anything or delete data. The app wakes up when you open it.
