How to Turn Off Background Apps on LG V30

If your LG V30 feels sluggish, drains its battery quickly, or uses too much mobile data, background apps are often the culprit. This guide shows you how to close and disable background apps on the LG V30 running Android 8.0 Oreo, helping you reclaim performance and extend battery life. You’ll learn quick methods for recent apps, a deeper dive into settings, and how to stop apps from auto-starting.

What You’ll Need

• Your LG V30 (any variant, as long as it’s running Android 7.0 Nougat or newer)
• Screen lock method (PIN, pattern, or password) if you have one set
• Optional: A list of apps you rarely use but that run in the background

Step-by-Step

Method 1: Close Recent Apps (Quick Swipe)

1. Tap the Square (Recent Apps) button at the bottom of the screen. It’s the rightmost of the three navigation icons.
2. You’ll see a carousel of all apps currently in your recent list. Swipe left or right to find the app you want to close.
3. Swipe the app’s preview upwards to dismiss it. This removes it from the recent list and closes it.
4. To close all background apps at once, tap the “Clear All� text at the bottom of the screen (it looks like a small broom icon).

Method 2: Force Stop via Settings (For Stubborn Apps)

Some apps, like social media or messaging, restart themselves quickly after you swipe them away. Use Force Stop for those.

1. Open the Settings app. You can find it in your app drawer or by swiping down from the top of the screen and tapping the gear icon.
2. Scroll down and tap “Apps & notifications.�
3. Tap “App info� (or “See all apps� depending on your software version).
4. Scroll through the list and tap the app you want to stop. For example, tap “Facebook� or “Instagram.�
5. On the app’s info page, tap “Force stop.â€� A confirmation dialog will appear.
6. Tap “OK� to confirm. The app will be terminated and will not run in the background until you open it again.

Method 3: Disable Auto-Run (Prevent Future Background Activity)

The LG V30 has a built-in “Smart Doctor� feature that lets you control which apps can auto-launch at startup or in the background.

1. Open Settings and tap “Smart Doctor� (usually near the top or under “General�).
2. Tap the “App management� card (it might say “Manage apps� or have a gear icon).
3. Tap “App permission� or “Auto-run� – the exact wording varies. Look for a section called “Auto-run apps.�
4. You’ll see a list of apps that are allowed to run in the background. Toggle off the switch next to apps you want to restrict. For example, turn off “Google Play Servicesâ€� if you don’t need instant sync, or turn off games you rarely play.
5. Be careful: disabling auto-run for essential system apps (like Phone, Messages, or Launcher) can cause issues. Only disable apps you don’t rely on for notifications or background updates.

Method 4: Use Battery Optimization

1. Go to Settings > Battery.
2. Tap the three-dot menu (top right) and select “Battery usage� or “Battery optimization.�
3. If you see “Battery optimization,â€� tap it. You’ll see a list of apps.
4. Tap an app and choose “Optimizeâ€� (or “Restrict background activityâ€�). This tells the system to put the app to sleep when you’re not using it.
5. For apps that misbehave, you can also tap “Battery usage� and then tap the app name to see its specific battery drain, then choose “Background restriction.�

Common Mistakes

• Force-stopping system apps: Apps like “Google Play Services,â€� “System UI,â€� or “Launcherâ€� are essential. Force-stopping them can cause crashes, missing notifications, or a frozen screen.
• Using a task killer app: Third-party task killers often do more harm than good. They force-stop apps that restart immediately, causing extra battery drain. The built-in methods are safer.
• Clearing all recent apps too often: Android is designed to keep some apps in memory for quick reopening. Clearing all apps frequently can actually make your phone slower because it has to reload everything from scratch.
• Ignoring the “Smart Doctorâ€� warning: If you disable auto-run for an app that needs to run for system stability, you might get a warning. Don’t ignore it; revert the change if you see unusual behavior.

Tips

• Check which apps use the most battery first: Go to Settings > Battery > Battery usage. Focus on apps that show high usage but that you rarely open. Those are the ones worth force-stopping or restricting.
• Use “Dozeâ€� mode: The V30 automatically enters Doze when the screen is off. You can help it by not moving the phone and keeping it face down if you don’t need notifications.
• Restrict background data: For apps that use too much data, go to Settings > Apps > App info > Data usage, and enable “Background data restriction.â€� This prevents them from syncing in the background.
• Reboot weekly: A simple restart clears temporary files and stops rogue processes. It’s a quick fix that often helps.
• Update your apps: Developers often fix background drain bugs in updates. Keep your apps updated via the Play Store.

Troubleshooting

Apps keep restarting after I force-stop them

Some apps are designed to restart via a system trigger (like a network change or alarm). To prevent this, you need to disable auto-run for that app (Method 3) and restrict its background activity (Method 4). If it still persists, the app might be a system app – you can’t permanently stop it without rooting, which is not recommended.

My phone is still slow after closing all apps

If closing background apps doesn’t speed things up, the issue might be low storage space. Go to Settings > Storage and check if you have less than 1GB free. If so, delete unused apps, clear cached data (Settings > Apps > App info > Storage > Clear Cache), or move photos/videos to an SD card.

I can’t find the “Auto-runâ€� option

On some V30 software versions (especially after updates), the auto-run menu is hidden. Try this: Settings > Apps > App info > tap the three-dot menu (top right) > “Show systemâ€� – then look for “Auto-runâ€� under the “Generalâ€� tab. If it’s not there, your carrier may have removed it. In that case, use the battery optimization method instead.

Notifications from an app stopped after I disabled it

That’s expected. If you want notifications back, re-enable the app’s auto-run or remove the battery optimization restriction. Go to Settings > Apps > App info > Battery > “Unrestrictedâ€� and set it back to “Optimizedâ€� (or just “Allowâ€� if it was “Restrictâ€�).

Frequently Asked Questions

Does swiping away an app really close it?

Yes, on the LG V30, swiping an app from the recent list removes it from memory. However, some apps (like music players) may keep running if they have a foreground service. Check the notification shade – if the app shows a persistent notification, swipe the notification away to fully stop it.

Will force-stopping an app delete my data?

No. Force-stop only halts the app’s process. Your login details, saved files, and settings remain intact. The app will start fresh the next time you open it, but your data is safe.

What’s the difference between “Force stopâ€� and “Disableâ€�?

Force stop ends the current running process, but the app can be restarted by you or by system triggers. Disable (Settings > Apps > App info > Disable) prevents the app from running at all and removes it from the app drawer. Disabling is more permanent, but it’s only available for non-system apps.

Is it safe to disable auto-run for all apps?

No. Some apps need to run in the background for core functions – for example, your messaging app needs to run to receive messages. Disable auto-run only for apps you rarely use, and avoid system apps like “Google Play Services� or “Android System.�

Will turning off background apps improve battery life significantly?

It depends on which apps you close. If you have apps that constantly sync (like email, social media, or news), yes, you’ll see a noticeable improvement. If you only have light apps, the effect may be minimal. The biggest battery drain is usually the screen, so also reduce brightness.

Can I set the V30 to automatically close apps after a certain time?

Yes, the “Smart Doctorâ€� feature has an option called “Auto-restartâ€� that can restart the phone at a scheduled time (e.g., 3 AM) to clear memory. It’s not exactly closing apps, but it achieves a similar effect. To set it: Settings > Smart Doctor > Auto-restart > toggle on and set a time.
