How to completely remove background apps on Android: 7 proven methods

Background processes are one of the main reasons brakes i battery discharge on smartphones Android. Even after closing the application, it can continue to work in hidden mode: updating data, sending notifications, or synchronizing files. As a result Xiaomi, Samsung or Realme with 8 GB of RAM they begin to “stutter” when opening the messenger, and the battery runs out in half a day.

The problem is aggravated by the fact that that manufacturers often they build dozens of system services into the firmware that cannot be disabled using standard means. For example, there are duplicate services, and advertising modules. Even after resetting to factory settings, they return. Samsung Galaxy This Knox, Bixby and duplicate services Google, and on Xiaomi — Mi Push, Security and advertising modules. Even after a factory reset they return.

In this guide we will examine all working methods removing background apps - from safe (via the settings menu) to radical (using ADB and root access). You will learn how to distinguish critical system processes from “garbage”, why you shouldn’t blindly disable everything, and what to do if notifications or mobile data stop working after cleaning.

⚠️ Attention: Some methods require unlocking the bootloader or superuser rights. This may lead to loss of warranty, malfunctions, or even bricking of the device. Before experiments, create a backup copy of your data via Settings → Google → Backup.

1. How to find and identify background apps

Before deleting something, you need to understand which processes really load the system. To do this, it is not necessary to install third-party utilities - the built-in tools are enough Android.

Open Settings → Applications and go to the tab All applications (on some firmware - Manage applications). all installed appsare displayed here, including system ones. Pay attention to the columns:

• 📊 Memory: Applications that occupy more than 500 MB often run background processes to data caching.
• ⚡ Battery: If a app consumes more than 5% of the charge per day, it is actively running in the background.
• 🔄 Autostart: Applications with startup permissions (BOOT_COMPLETED) are launched when you turn on the phone.

More detailed information is provided by the menu Settings → Battery → Battery usage. Here you can see which apps are using up power even when the screen is off. For example, Facebook or Instagram can "eat up" up to 20% of the charge per day due to background synchronization.

For advanced users, a hidden tool is useful - Developer Options (Developer Mode). To activate it:

1. Go to Settings → About phone.
2. Find the item Build number and tap on it 7 times.
3. Return to the main settings menu - a new section will appear For developers.

Open inside it Processes (or Services on some firmware). It displays all active processesincluding system ones, indicating RAM and CPU consumption. Caution: not all of them can be safely stopped!

2. Safely disabling background apps through settings

If you are not ready to risk system stability, start with standard methods. They do not require root access and are suitable for 90% of users.

2.1. Limiting autorun

Many applications launch automatically when you turn on the phone or connect to the Internet. To stop this:

1. Go to Settings → Applications.
2. Tap on the three dots in the upper right corner and select Special access → Autorun.
3. Disable startup for unnecessary apps (for example, games or instant messengers that you rarely use).

2.2. Battery optimization

Function Battery optimization (or Adaptive battery on new versions Android) automatically limits the background activity of little-used applications. It is activated like this:

• 🔋 Settings → Battery → Battery optimization.
• 📱 Select All applications and add to the list optimizations are those that should not run in the background (for example, TikTok or AliExpress).

⚠️ Attention: Do not add messengers to this list (WhatsApp, Telegram) if you want to receive notifications on time. Battery optimization may block their background operation.

2.3. Forced stop

To immediately close the background process:

1. Open Settings → Applications.
2. Select the desired application and tap Force stop.
3. Confirm the action.

This method is temporary - the application will start again the next time you open or reboot. For a permanent effect, you need to disable autorun (see paragraph. 2.1).

3. Using Developer Options for deep cleaning

Developer mode allows limit the number of background processes and disable animations, speeding up the system. However, incorrect settings. may lead to failures!

3.1. Limiting background processes

In the menu For developers find the parameter Limit background processes (or Process limit). Here you can choose:

• 🛑 No background processes —a radical option, it can break notifications.
• ⚠️ No more than 1 process —a compromise for weak devices.
• ✅ Standard limit —recommended for most users.

⚠️ Attention: After changing this parameter, some applications (for example, music players or navigators) may stop work in the background. Test the setting gradually.

3.2. Disabling unnecessary animations

This will not remove background apps, but will make the interface faster. Developer Options install:

• Window animation scale → Animation disabled
• Transition animation scale → Animation disabled
• Animator duration → Animation disabled

3.3. Disabling background error checking

The system process Error Reporting constantly scans the logs for failures. For most users, it is useless:

1. B Developer Options find Disable error checking.
2. Activate the switch.

This will free up to 50 MB of RAM and reduce the load on the processor.

4. Removing system applications without root (via ADB)

Some manufacturers (Samsung, Xiaomi, Huaweiinstall tens of unnecessary system applicationsthat cannot be removed using standard methods. For example:

• 🎵 Samsung Music (duplicates Google Play Music)
• 📺 Mi Video (on Xiaomi)
• 🤖 Bixby (voice assistant Samsung)
• 📰 News & Weather (weather widget from HTC)

Delete they can be done through ADB (Android Debug Bridge) - a debugging tool that does not require root access. Advantage: applications are completely removed, not just hidden.

4.1. Preparation for working with ADB

You will need:

• 🖥️ Computer with Windows, macOS or Linux.
• 📱 USB cable (preferably original).
• 🔧 Utility ADB (download Platform Tools from the official website Google).

Action algorithm:

1. Unpack Platform Tools into a folder (for example, C:\adb).
2. Turn on phone USB debugging v Developer Options.
3. Connect your smartphone to the PC and select mode File transfer.
4. Open the command line (cmd) in the folder with ADB and enter:

adb devices

If the device is displayed in the list, you can proceed with removal.

4.2. Commands for removing system applications

First get a list of all packages:

adb shell pm list packages

Then remove the unnecessary application with the command:

adb shell pm uninstall -k --user 0 package name

Examples of popular packages to remove:

Application	Name package	Manufacturer
Bixby	com.samsung.android.bixby.agent	Samsung
Mi Music	com.miui.player	Xiaomi
Facebook App Manager	com.facebook.appmanager	Meta
Google Play Music	com.google.android.music	Google

⚠️ Attention: Do not delete packages with names com.android., com.google.android.gsf or com.qualcomm. —these are critical system components. Deleting them will lead to a failure!

How to return an application deleted via ADB?

If you accidentally deleted the desired package, you can only restore it through a full reset or flashing it. Therefore, before experiments, write down the commands in a notepad.

5. custom firmware

If you are willing to take the risk, root access give full control over the system. With their help you can:

• 🧹 Delete any system applications without restrictions.
• 🔧 Freeze processes using Titanium Backup or Greenify.
• 📉 Disable system services (Google Play Services, Location History).

However, there are also disadvantages:

• ❌ Loss of warranty (on most devices).
• ⚠️ Risk of being “bricked” in case of an error.
• 🛡️ Vulnerability to viruses (root access bypasses protection Google Play Protect).

5.1. Obtaining root access

The most popular methods:

• 🔓 Magisk —a universal method for most devices.
• 📱 KingRoot —simple, but less reliable.
• 🔧 Manual patching boot.img via TWRP (for advanced).

Instructions for Magisk:

1. Unlock the bootloader (fastboot oem unlock).
2. Install custom recovery (TWRP).
3. Flash the ZIP file Magisk via recovery.
4. Reboot and check root using Root Checker.

5.2. Removing system applications from root

Suitable for this:

• 🗑️ Titanium Backup — allows you to delete and freeze packages.
• 🧊 Greenify — “freezes” background processes without deleting.
• 🔍 Root Explorer — manual deletion of files from /system/app.

⚠️ Attention: Before deleting system files, always make a backup copy of the folder /system! bloatbootloop).

5.3. Custom firmware without bloat

If you are tired of the manufacturer's built-in applications, consider the firmware:

• 🤖 LineageOS — clean Android without bloat.
• ⚡ Pixel Experience —firmware with functions Google Pixel.
• 📱 Havoc-OS —customizable firmware with many settings.

Installing custom firmware requires an unlocked bootloader and TWRP. Find detailed instructions on the forum XDA-Developers for your model.

6. Third-party utilities for managing background processes

If you don’t want to delve into the settings, you can use specialized applications. They automate cleaning, but require caution.

6.1. data-i="270">does not delete applications, but

Greenify does not delete applications, but "freezes" them, preventing background activity. Suitable for:

• 📱 Social networks (Facebook, Instagram).
• 🎮 Games with aggressive background synchronization.
• 📰 News applications (Yandex.News, Google News).

How to use:

1. Install Greenify from Google Play.
2. Launch and select applications for hibernation.
3. Activate the option Automatic hibernation.

6.2. SD Maid (with root)

SD Maid - a powerful cleaner that finds and removes:

• 🗑️ Residual files of deleted applications.
• 🔍 Duplicates of system libraries.
• 📦 Unnecessary APK files in the cache.

For full operation, root access is required Without. their functionality is limited.

6.3. Brevent (alternative to Greenify)

Brevent blocks background activity at the kernel level, but only works on Android 7.0 and newer. Advantage - does not require root, but requires activation through ADB:

adb -d shell sh /sdcard/brevent/brevent.sh

⚠️ Attention: Some antiviruses. (for example, Avast or Dr.Web) may be marked Brevent as malware. This is a false positive - the application is safe.

7. broken

Even with careful actions, sometimes problems arise:

• 📵 Notifications do not arrive.
• 🌐 mobile data does not work.
• 🔋 The battery drains quickly.

Here's how to fix them:

7.1. Restoring notifications

If you stop receiving messages from instant messengers:

1. Check if the battery is optimized for the application (Settings → Battery → Battery optimization).
2. Enable autostart for the messenger.
3. B Developer Options disable Limit background processes.

7.2. mobile data

If 3G/4G disappears after deleting system applications:

• 📶 Restart the phone.
• 🔄 Manually select the operator in Settings → Mobile network → Network operators.
• 🔧 Reset network settings: Settings → System → Reset → Reset Wi-Fi, mobile network and Bluetooth settings.

7.3. Quick battery drain after cleaning

It’s paradoxical, but sometimes after removing background apps the battery drains even faster. Reasons:

• 🔄 The system rebuilds the cache and indexes the data.
• 📊 The remaining processes receive more resources and work more intensively.
• 🔋 Background synchronization has turned on. (check Settings → Accounts).

Solution: wait 1-2 days (the system will stabilize) or recover deleted applications via ADB:

adb shell cmd package install-existing package name

7.4. Extreme measures: reset to factory settings

If the phone becomes unstable (freezes, overheats, turns off), perform a full reset:

1. Create a backup copy of your data.
2. Go to Settings → System → Reset → Delete all data.
3. After resetting, do not restore data from backup - install applications manually to avoid re-infection with "background garbage".

FAQ: Frequently asked questions about background apps on Android

Is it possible to completely disable all background apps? processes?

No, this will lead to the crash of the system. Critical Processes (for example, android.process.media or com.android.phone) are responsible for the operation of telephony, Wi-Fi and the interface. Disabling them will make the phone inoperable.

The maximum that can be done is to limit background activity third-party applications (social networks, games, instant messengers).

Why, after deleting an application via ADB, does it return after updating?

Manufacturers often restore system applications when updating firmware. To avoid this:

• Disable automatic system updates.
• Use Magisk to block updates for specific packages.
• Install custom firmware without bloat.

How to find out which application loads the processor in the background?

Use the built-in activity monitor:

1. Enable Developer Options (see section 1).
2. Open Processes or Services.
3. Pay attention to the column CPU —here you can see which processes consume the most resources.

For detailed analysis, use CPU Monitor or Simple System Monitor from Google Play.

Is it safe to use applications like "Clean Master" to clean the background?

No, most "cleaners" (for example, Clean Master, DU Speed Booster) themselves become a source of background activity. They:

• Show false warnings about “contamination” of the system.
• Launch their own services for “monitoring”.
• Can collect user data.

Built-in tools are sufficient for cleaning Android or proven utilities like SD Maid (with root).

How to disable background activity of Google Play Services?

Google Play Services is a critical component, but it can be partially limited:

1. Open Settings → Applications → Google Play Services.
2. Tap Battery → Optimization and select Limit.
3. Disable unnecessary features in Settings → Google → Google Services (for example, Advertising or History locations).

⚠️ Attention: Complete shutdown Google Play Services will break the operation of Google Play, Gmail and other services Google.
