I removed the apps by mistake From here,it is here. 

The device was choosing applications 

Will the device return to choose from itself and put the applications in deep dormancy

If you remove apps from the Deep sleep list, the phone won’t add them back automatically. You’ll need to add them manually again through Battery & device care → Battery → Background usage limits. The system may move unused apps to Sleeping apps, but not back to Deep sleeping apps.

Is there a solution for me? Put them alone.

[Rahul_Radhakrishnan]

Unfortunately, there isn’t an option to keep specific apps out of the Deep sleep list permanently. If you want to make sure your apps run normally, the best way is to remove them from Deep sleep and keep checking under Battery & device care → Battery → Background usage limits. You may need to re-add them manually if the system moves them. Another option is to disable 'Put unused apps to sleep' in the same settings, but this could use more battery.

Will reset the settings for the device return the system to its state?

Is it better to remove all applications?

[Rahul_Radhakrishnan · Accepted solution]

Resetting the settings (from General management → Reset → Reset all settings) will only return system settings like Wi-Fi, Bluetooth, app preferences, etc. to their defaults. It won’t uninstall apps or erase your data. However, it also won’t stop the phone from putting apps to sleep again in the future, since that behavior is part of Samsung’s power management.

It’s not necessary to remove all applications from the Deep sleep list. You only need to remove the ones you use regularly (like messaging, email, music, or fitness apps) so they work properly in the background. Leaving less important apps in Deep sleep is actually good, since it helps save battery.

So, best approach:

Keep essential apps out of Deep sleep.

Let non-essential ones remain there for better battery life.

Thank you for your information.

If you remove apps from the Deep Sleep list, they won’t be automatically added back by the system. You’ll need to manually re-add them by navigating to:
Battery & device care → Battery → Background usage limits.
While the system might move unused apps to the Sleeping apps list, it will not place them back into Deep sleeping apps on its own.
