Disabling Background Apps on Android: A Step-by-Step Guide

Introduction

Background apps on Android can silently drain your battery and system resources even when you're not using them. This leads to reduced battery life, slower device performance, and unwanted notifications. Disabling unnecessary background apps is a simple and effective way to improve performance and extend battery life. In this guide, you'll learn how to easily do this using standard Android settings.

Requirements

Before you begin, ensure that:

• You have a device running Android 8.0 (Oreo) or newer to support modern background process management features.
• Access to the device's Settings (administrative rights are not required).
• The interface may vary slightly depending on the manufacturer (Samsung, Xiaomi, Huawei, etc.) and Android version, but the general steps remain similar.
• It is recommended to create a system restore point (if supported) before making changes, especially when working with system apps.

Step-by-Step Instructions

Step 1: Opening App Settings

On your device's home screen, locate and open the Settings app (gear icon). Scroll down the list and select the Apps or Apps & Notifications section (on some firmware it may be called Application Manager). This section contains a complete list of installed apps.

Step 2: Stopping Background Apps

In the opened app list, find those that you believe are running in the background. Typically, these are messengers (WhatsApp, Telegram), social networks (VK, Facebook), or news apps. Tap on the selected app to go to its settings page. Press the Stop or Force Stop button (the name may vary). Confirm the action in the dialog box if it appears. Repeat this step for all unnecessary background apps.

⚠️ Important: Some system apps (e.g., system interface, Google services) cannot be stopped without root access. Avoid stopping critical components to prevent device malfunctions.

Step 3: Disabling Auto-start

To prevent apps from automatically launching after a device reboot or certain events (e.g., when connected to a network), disable their auto-start. Return to the main Settings menu and find the Auto-start section. It may be located under subsections like Accessibility, Additional Settings, or Security. In the list, disable the toggles for apps that shouldn't launch automatically.

If there is no Auto-start section in the general settings, check the settings of individual apps: some programs (e.g., messengers) have their own auto-start option in their parameters.

Step 4: Activating Battery Saver Mode

Android includes a built-in Battery Saver mode that automatically restricts background app activity, reduces processor performance, and disables some features. Go to Settings → Battery (or Battery & performance). Toggle on the Battery Saver mode. You can configure its activation: manually, at low charge (e.g., 15%), or on a schedule. This mode also restricts background data for apps.

Step 5: Checking Background Processes (Optional)

For more advanced users who want detailed control over background processes, you can use Developer Options. To enable them:

1. Go to Settings → About phone.
2. Find Build number and tap it 7 times until you see the message "You are now a developer!".
3. Go back to Settings and find the new Developer options section.
4. In it, select Running processes or Active apps. Here you'll see a list of active background processes and can stop unnecessary ones manually (be careful, avoid system processes).

Checking Results

After completing all steps, check the effectiveness:

• Battery: Open Settings → Battery and check the usage graph. Background app consumption should decrease.
• Performance: The device should respond faster, and app transitions smoother.
• Notifications: The number of pop-up notifications from background apps (e.g., ads) should decrease.
• If something goes wrong (e.g., an important app stops working), reboot your device—this restores default behavior.

Possible Issues

• Error "App not stopped" or Stop button unavailable: This is a system app or service that cannot be terminated without root access. Don't insist to avoid crashes.
• Apps automatically restart after being stopped: Likely auto-start is enabled or they're tied to system events. Check Step 3 and disable auto-start. Some apps (e.g., antivirus apps) may be protected from being stopped.
• Battery Saver mode doesn't reduce battery drain: Ensure it's enabled and check the mode's exception list. Some apps may be added to exceptions and continue running in the background.
• Loss of important notifications: After disabling background apps (especially messengers), you might not receive messages promptly. Solution: Only disable unnecessary apps, or set up priority notifications for important apps in their own settings.
• Settings interface differs: On some manufacturer firmware (Xiaomi, Huawei), sections may be named differently. Use the settings search with keywords like "apps", "auto-start", "battery".
