Your phone's battery drain often stems from hidden software processes running constantly in the background. When you aren't actively using an app, it might still sync data, check for updates, and consume precious RAM. On many modern Android devices, you can stop this completely by utilizing a built-in power management setting. Learning how to put apps in permanent slumber stops unauthorized background activity, extends battery life, and speeds up sluggish devices.
Placing software into permanent deep sleep means it will never run in the background again until you open it manually. Standard sleeping apps can wake up if the operating system thinks they need to sync, but deep-sleeping applications stay frozen. This guide breaks down how the feature works, step-by-step instructions for popular devices, common mistakes to avoid, and answers to frequent questions about battery management.
Understanding Background App States
Operating systems manage installed software through distinct resource tiers. Standard apps run freely, fetching notifications and refreshing content whenever they choose. Over time, manufacturers introduced tiered restrictions to curb excessive power consumption.
Standard sleeping apps enter a semi-dormant state after days of inactivity. They consume fewer resources, but they can still wake up if you receive a notification or if another service requests data.
Permanent deep sleep, by contrast, acts as a hard stop. Software placed in this category will not check for updates, send push notifications, or run background tasks. If you want a deep-sleeping application to work, you must tap its icon and open it yourself. Once you close it, it immediately goes back into hibernation. This approach is ideal for utility tools, calculators, document readers, and shopping apps you open once a month.
Step-by-Step Guide to Restricting Background Apps
Most prominent implementations of permanent app hibernation appear on Samsung Galaxy devices running One UI. The process takes less than a minute.
- Open the Settings app on your phone or tablet.
- Scroll down and tap Battery (or Battery and device care on older software versions).
- Select Background usage limits from the menu options.
- Tap on Deep sleeping apps to view your current restricted software list.
- Tap the plus icon or Add apps button at the bottom of the screen.
- Select the software you want to restrict from your installed list, then tap Add.
You can also toggle on the option to put unused software to sleep automatically. The operating system monitors your habits and flags programs you haven't opened recently, moving them down resource tiers automatically. If you ever need to reverse a restriction, you can return to the deep sleep list, tap the menu dots, select remove, and choose the software to pull it back into regular circulation.

Common Mistakes When Restricting Background Apps
While freezing background software saves power, applying restrictions blindly causes frustrating user experience issues. Avoid these common pitfalls when managing your device.
- Freezing messaging apps: Never put instant messaging tools, SMS clients, or work communication software into deep hibernation. Because these apps rely on instant background polling to deliver alerts, deep sleep prevents incoming messages from reaching you until you open the app manually.
- Restricting smart home controls: Apps that manage home security cameras, smart thermostats, or wearable fitness trackers require continuous background syncing to alert you to emergencies. Keep them in your unrestricted list.
- Ignoring automatic update conflicts: Deep sleep can occasionally pause automatic updates for specific tools managed through app stores. If you notice a piece of software failing to update, check your battery restriction lists first.
- Over-restricting navigation tools: Map applications and transit trackers need background location permissions and active data links to provide turn-by-turn routing. Putting them to sleep breaks active navigation when your screen turns off.
Frequently Asked Questions
Will putting apps in permanent slumber delete my saved data?
No. Hibernation only stops background processes and resource usage. Your login credentials, saved preferences, and stored documents remain untouched. The software simply stays inactive until you launch it again.
How do I stop important apps from going to sleep?
Most device settings menus include a "Never sleeping apps" category alongside deep sleep options. You can manually add critical tools—such as your banking apps, email clients, or authenticator apps—to this whitelist to ensure they always maintain full background privileges.
Does deep sleep improve phone performance?
Yes. Limiting active background processes frees up random access memory and reduces processor strain. This leads to cooler device temperatures, smoother scrolling, and noticeable improvements in overall daily battery longevity. For more tips on maintaining mobile hardware, visit Samsung Support.
Can I use this feature on non-Samsung devices?
While Samsung offers the most explicit "Deep Sleeping Apps" menu, stock Android devices feature similar controls under adaptive battery settings and restricted background buckets. Manufacturers often label these controls differently, such as background optimization or battery restriction limits.
