Background applications on Android: what are they, how to find them and delete them permanently

Have you ever noticed that your smartphone begins to slow down, quickly discharge or heat up for no apparent reason? The culprit is often Android starts to slow down, quickly discharge or overheat for no apparent reason? The culprit is often background applications apps that continue to run even after being closed. They consume processor resources, RAM and battery power, reducing the performance of the device.

Many users mistakenly think that it is enough to press a button "Collapse" or swipe up on the application card in the multitasking menu to close it completely. In fact, most applications continue to perform tasks in the background: updating data, sending notifications, or synchronizing with servers. Social networks (Facebook, Instagram), instant messengers (WhatsApp, Telegram) and games with online components behave especially aggressively.

In this article we will look at what background processesthey are, how to detect them (including hidden system services), and we will provide step-by-step guide with photoshow to get rid of them without harming the phone. You will also learn which applications can be safely disabled, and which are better to leave - and why.

What are background applications and why they are dangerous

Background applications - these are apps that continue to perform tasks after the user has stopped interacting with them. They are divided into three types:

• 🔄 Synchronization services: update data (mail, calendar, contacts) without your participation. Example: Gmail or Google Drive.
• 📱 Push notifications: messengers and social networks maintain a constant connection with servers to instantly deliver messages.
• 🎮 Hidden processes: some games and applications run background tasks to collect analytics or display advertising (for example, AliExpress or TikTok).

Why is this bad? Background processes:

• ⚡ Reduce battery life by 20–40% (according to research Android Authority for 2023).
• 🐢 They slow down the phone, taking up to 30–50% RAM.
• 🔥 Cause processor overheating, especially on budget smartphones (Redmi, Samsung Galaxy A-series).
• 📡 Increase the consumption of mobile traffic (some applications drain up to 1–2 GB per month).

The most insidious feature of background applications is them invisibility. They are not displayed in the notification panel and are not always visible in the task manager. For example, Facebook can run up to 5–7 background ones. processes at the same time, even if you have not opened the application for a long time.

⚠️ Attention: Some system services (for example, com.android.systemui or Google Play Services) are critical for the operation of Android. Forcibly disabling them can lead to crashes or the phone crashing bootloop (infinite reboot).

How to check which applications are running in the background

Before disabling something, you need to identify the “culprits”. Here 3 ways find background applications on Android:

Method 1: Built-in task manager

The simplest method is to use standard system tools:

1. Open Settings → Applications.
2. Tap on the three dots (⋮) in the upper right corner and select Show system.
3. Sort the list by Memory usage or Battery charge.

Applications consuming >100 MB RAM or >5% battery in the background are prime candidates for shutdown.

Method 2: Battery Tool

A more accurate analysis is provided by the energy consumption section:

1. Go to Settings → Battery → Battery usage.
2. Click on the graph and select Background consumption (on some firmware — Details).
3. Look for applications marked Works in the background.

The screenshot below shows that Instagram consumes 18% charge, although it was not actively used:

Method 3: Third-party utilities (for advanced)

If you want deep analysis, install one of these applications (available in Google Play):

• 🛠️ Greenify - suspends background processes without root access.
• 🔍 AccuBattery - shows detailed statistics on battery consumption by applications.
• 📊 Simple System Monitor —displays active processes in real time.

⚠️ Attention: Applications like Clean Master or DU Battery Saver often become the source of background processes. Use them with caution or delete them after analysis.

How to disable background applications: step-by-step guide

Now let's move on to practice Below - 4 proven methods, from the most. safe to radical (require root access). Let's start with the simplest:

Method 1: Limiting background activity (without root)

This method works on all versions Android from 6.0 and above:

1. Open Settings → Applications.
2. Select an application (for example, Facebook) and tap Battery.
3. Activate the option Limit background activity (on some phones - Optimize).
4. In the section Notifications disable Show notifications.

This method does not remove the application, but significantly reduces its impact on performance.

Method 2: Disable autorun

Many applications start automatically when you turn on the phone To do this. stop:

1. Go to Settings → Applications → Autorun (on Xiaomi, Huawei, Oppo).
2. On Samsung different path: Settings → Optimization → Autorun.
3. Disable unnecessary applications (for example, games or stores like AliExpress).

The screenshot shows an example for Redmi Note 10:

Method 3: Forced stop (radical)

If the application stubbornly does not want to “die”, you can forcefully stop it:

1. B Settings → Applications select the one you need.
2. Click Force stop (on some firmware - Stop).
3. Confirm the action.

⚠️ Important: After rebooting the phone, the application may start again. To avoid this, combine this method with disabling autorun.

Method 4: Freezing via ADB (for experienced)

If you have a PC and are ready to experiment, you can “freeze” the application via ADB (Android Debug Bridge):

adb shell pm disable-user --user 0 com.facebook.katana

Where com.facebook.katana —package name Facebook. To find the package name of any application, use the command:

adb shell pm list packages | grep "keyword"

⚠️ This method requires enabled USB debugging and may cause crashes if the system application is frozen.

Which applications can be disabled and which cannot

Not all background processes are equally useful. Here a list of what you can and cannot touch:

✅ Safely disable

• 📱 Social networks: Facebook, Instagram, TikTok - they aggressively consume resources even in the background.
• 🎮 Games: Clash of Clans, PUBG Mobile, Genshin Impact - often launch background tasks for updates.
• 🛒 Stores: AliExpress, Wildberries, Ozon - monitor your activity and show notifications.
• 📰 News applications: Yandex.News, Google News - constantly update the feed.

❌ Dangerous to disable

• 🔒 System services: Google Play Services, Android System, com.android.phone - critical for the operation of the phone.
• 📞 Telephone services: com.android.dialer, Telecom - are responsible for calls and SMS.
• 🔄 Synchronization: Contacts, Calendar —without them contacts and events will not be updated.
• 🛡️ Security: Google Play Protect, Device Health Services —protect against viruses.

If in doubt, check the application through the search in Google by request type "is it possible to disable [package name] on Android". For example, com.sec.android.app.launcher is a launcher Samsung, and disabling it will cause the interface to crash.

⚠️ Attention: On some firmware (for example, MIUI from Xiaomi or EMUI from Huawei) disabling system applications may block access to proprietary functions such as Game Turbo or App Twin.

How to permanently remove unnecessary background applications

If restrictions and stops do not help, there remains radical method - deletion. There are two options here:

Option 1: Removal through settings (for regular applications)

1. Open Settings → Applications.
2. Select an application (for example, Facebook) and click Delete.
3. If the button is inactive, first click Disableand then Delete.

Some pre-installed applications (for example, Google Duo or YouTube Music) cannot be completely removed, but you can disableso that they do not interfere.

Option 2: Uninstalling system applications (requires root)

To remove built-in applications (for example, Bixby on Samsung or Mi Browser on Xiaomi) you will need root access and an application like Titanium Backup or Root Uninstaller:

1. Get root access (for example, through Magisk).
2. Install Titanium Backup from Google Play.
3. In the list of applications, find the unnecessary one and select Delete.

⚠️ Warning: Removing system applications can lead to:

• 🔄 Endless reboot (bootloop).
• 📵 Loss of functionality (for example, the camera or Bluetooth will disappear).
• 🔒 OTA update block (over the air).

If you are not sure, it is better to freeze application (option Freeze v Titanium BackupThis will allow you to return it back without flashing it.

How to prevent. the appearance of background applications in the future

In order not to constantly struggle with background processes, follow these tips:

• 🛡️ Install applications only from Google Play. Third-party APKs often contain hidden services for collecting data.
• 🔍 Check permissionsIf the messenger asks for access to geolocation or contacts for no reason - refuse.
• 📱 Use "Light" versions. For example, Facebook Lite or Messenger Lite consume 2-3 times less resources.
• 🔄 Clear your cache regularlyclick Settings → Storage → Cache data click Clear.
• 🛠️ Update the firmwareIn new versions Android (12+), control over background data has been improved. processes.

• 🚫 Disable everythingFor example, they turn off Google Play Servicesand then stop working Google Maps, Gmail and other services.
• 🔄 Use "cleaners" like Clean MasterThese applications themselves become the source of background processes and often show false threats.
• 📵 Close all processes manually. Android optimized for multitasking, and force closure system services can degrade performance.
• 🔒 Delete system applications without a backup. This can lead to brick (turning the phone into a “brick”).
