Managing mobile device resources often becomes a stumbling block for users who notice system slowdowns or rapid battery drain. Application Manager is a central hub through which you can control running processes, free up RAM and fix frozen apps. In the Android ecosystem, the approach to this tool has changed dramatically with each new version of the operating system, which often causes confusion among owners of smartphones of different generations.
Users used to be able to easily access a list of all active tasks through the Menu button or a special switch, but modern interfaces have hidden these capabilities deeper in the settings. Today, in order to find and open the desired section, you need to understand the difference between simply switching windows and fully managing services in the developer menu. We will analyze all the available ways to access these functions on various shells, such as MIUI, One UI and clean Android.
It is important to immediately note that thoughtlessly closing all processes can lead to the opposite effect: the system will spend more energy on restarting important services. Therefore, before you start “cleaning”, it’s worth figuring out exactly what tools your OS version offers for activity monitoring. Below we will describe in detail the ways to access these settings and explain how to use them effectively.
Evolution of task management in Android versions
The history of the development of the task management interface in Android goes back more than ten years, and each major release brought its own changes to the logic of working with memory. In earlier versions, such as Android 4.0 Ice Cream Sandwich i 5.0 Lollipop, there was an explicit list of running applications, which was accessed by long pressing the Home button. This allowed the user to see not only previews of windows, but also buttons for forced stop.
With the release of Android 6.0 Marshmallow and subsequent versions, Google's philosophy changed: the system itself began to more aggressively manage background processes, believing that the user should not interfere with this work manually. Recent applications menu transformed into a visual task switcher, where the “Close all” function became basic, and access to technical information was hidden. This decision was dictated by the desire to simplify the interface for the mass user.
⚠️ Attention: In modern versions of Android (starting from 10 and higher), the standard multitasking menu does not show the actual consumption of processor resources or the exact amount of RAM used for each application.
Currently moment, if you are using a device with a shell from a third-party manufacturer, the situation may be different. The company Samsung in its interface One UI retained deeper access to memory management through the sidebar, while Xiaomi in MIUI moved the memory clearing button to the main multitasking screen. Understanding these differences is critical to properly configuring the device.
It should also be taken into account that many pre-installed “cleaners” from manufacturers are often just a marketing ploy. They create the illusion of vigorous activity by shutting down processes that the system will immediately restart. Real control is only possible through system settings or specialized debugging tools.
Standard access methods through the settings menu
The most reliable and universal way to find information about running apps is to use the standard smartphone settings menu. This method works on most devices regardless of firmware version, although the names of the items may vary slightly. First, you need to go to the main menu and find the section responsible for the operation of the device.
In pure Android, the path usually looks like this: you need to open Settings, then select the item Applications or Applications and notifications. Inside this section you will see a complete list of installed software. Here you can select a specific app and press the button Stopif it is active. This action is equivalent to forcefully ending the process through the task manager.
Device users Samsung can find extended information in section Device maintenance or Battery and device care. This often includes visualization of memory and CPU usage over the last 3, 7, or 15 days. By clicking on the graph or list, you can see which applications are consuming the most resources in the background.
- 📱 Go to
Settings→Applicationsto view the full list of apps. - ⚙️ Use the search in settings by entering the word “Applications” to quickly find the desired section.
- 🛑 The “Stop” button is available only for third-party applications, protect system services from being closed.
It is worth remembering that in this menu you manage applications one at a time, which is convenient for diagnosing a specific problem, but inconvenient for mass cleaning. If your goal is to quickly free up memory before launching a heavy game, this method may seem too slow compared to hardware buttons or gestures.
Use the search in Settings (the magnifying glass icon at the top of the Settings screen) to instantly find the Applications section without wandering through complex manufacturer menus.
Using the Developer Menu
For For those who need a professional monitoring tool, the Android system offers a hidden section - Menu for developers. This is where the analogue of the classic task manager is located, which displays running services in real time. However, by default this section is hidden from the eyes of the average user for security purposes and to prevent accidental breakdown of the system.
To activate this mode, you need to go to the section About phone or System information in the settings. Find the item Build number and quickly click on it 7 times in a row. After a few clicks, the system will ask you to enter your PIN code or pattern, and then inform you that you have become a developer. After this, a new item will appear in the main settings menu For developers.
Inside this section you need to find the item Running Services or Running Services. Once you open it, you will see a list of all currently active processes, the amount of random access memory (RAM) they occupy and the time of continuous operation. This is the most accurate tool for identifying “parasitic” applications that quietly drain your battery.
Settings → For Developers → Running ServicesIt is important to understand the risks of using this section. Forcibly stopping system services through this menu can lead to unstable operation of the phone, network failures, or even a cyclic reboot. It is highly not recommended to interfere with processes whose names you do not understand without first studying the documentation.
⚠️ Attention: Changing settings in the developer menu may void the software warranty in some service centers. Be extremely careful when disabling system services.
What to do if the “Build Number” item is not found?
On some devices (for example, older HTC or Sony models), activating developer mode may require clicking not on “Build Number”, but on “Kernel Version” or “MIUI Version”. Try to quickly click on all items containing the word “Version” or “Build”.
Features of interfaces from different manufacturers
Large smartphone manufacturers strive to stand out not only with hardware, but also with software functions, so they often modify the standard application management mechanism. This creates a situation where the instructions for one brand are completely different for another. Let's look at the key differences in popular shells.
Owners of smartphones Xiaomi, Redmi and POCO with a shell MIUI or HyperOS have access to the memory clear button directly in the menu multitasking. When you click on the “Close All” button (usually a cross or broom icon), the system does not simply minimize windows, but tries to unload processes from RAM. In addition, these shells have a separate Security application, which functions as an advanced task manager with game acceleration features.
Devices Samsung with shell One UI offer the “Edge Panel” function. If you activate it in the display settings, then when you swipe from the edge of the screen, a toolbar appears with tools, including “Memory Cleaner”. This allows you to free up resources without interrupting your current work in another application. Also, in the recent applications menu at the bottom there is often a “RAM” button showing the free amount of memory.
| Brand / Shell | Location of the cleanup button | Additional functions |
|---|---|---|
| Xiaomi (MIUI) | Task menu (cross) | Security application, game acceleration |
| Samsung (One UI) | Side panel / Task menu | RAM widget, auto-optimization at night |
| Google Pixel | Absent (swipe only) | Adaptive battery, deep sleep |
| Huawei (EMUI) | Task menu (broom icon) | Phone manager, one-touch optimization |
On devices Google Pixel and other smartphones with pure Android, the approach is as minimalistic as possible. There are no explicit buttons to clear memory, as the system relies on artificial intelligence algorithms to decide which processes to keep in memory and which to unload. The user is only asked to swipe up applications to close them, which in fact only removes them from the list of recent ones, but does not always stop code execution.
Manufacturers add their own cleaning tools, because the standard Android mechanism often seems to users not efficient enough to free up RAM.
Third-party solutions and manager applications
If the built-in capabilities of the system are not enough for you, the store Google Play offers thousands of applications positioning themselves as advanced task managers. Among them are such popular solutions as Greenify, Files by Google or complex combines like CCleaner. These apps promise not only to close applications, but also to analyze their behavior, preventing autostart.
The application Greenify, for example, uses a unique "hibernation" approach. Instead of constantly closing the application, it puts it into sleep mode, preventing any background activity until the user opens the app. This is especially useful for social networks and instant messengers, which tend to keep the connection constantly active.
However, using third-party software has its pitfalls. Such applications themselves consume resources, run in the background and require broad permissions to access data. In some cases, they can conflict with system power-saving mechanisms, resulting in notifications from important apps no longer arriving on time.
- 🚀 Greenify great for “putting to sleep” rarely used applications.
- 🧹 Files by Google safe and helps clear the cache without affecting system processes.
- ⚠️ Avoid applications that promise to “speed up your phone 5 times” - this is most often marketing.
Before installing any manager, carefully read reviews and check permissions. If an application requires access to contacts or microphone for the “memory cleaning” function, this is a clear sign of malware or low-quality software. Trust only trusted developers with a good reputation.
Optimizing background activity and autorun
Simply closing applications from the manager often gives only a temporary effect. A much more effective method is to set restrictions on background activity and autorun. This allows you to prevent unnecessary processes from starting even before they begin to consume resources.
In the settings of any specific application (via the menu Settings → Applications), you can find the section Battery or Battery consumption. There are usually three operating modes: “Unlimited”, “Optimized” and “Limited”. Selecting a mode Limited prevents the application from running in the background when you are not using it. This radically reduces energy consumption and the load on the processor.
For To control startup on some devices (especially Chinese brands), there is a separate item in the settings, which is called - Autostart. Here you can check off those apps that are allowed to start immediately after turning on the phone. It is recommended to leave only instant messengers and the alarm clock here, and turn off everything else.
⚠️ Attention: If you limit background activity for instant messengers (WhatsApp, Telegram), you may stop receiving messages instantly. They will come only after you manually open the application.
It is also worth paying attention to the “Adaptive Battery” feature, which appeared in Android 9 and became standard. It learns your usage habits and automatically limits rarely used apps. Make sure that this function is enabled in the section Battery, as it works more efficiently than any manual cleaning of the manager.

Frequently asked questions
Why does the memory quickly fill up again after closing all applications?
This is normal behavior of the Android operating system. The way memory works is that free RAM is useless RAM. The system pre-loads frequently used applications into memory so that they open instantly. If you force clear memory, the system will immediately start reloading the necessary services, which will require more processor power than if they simply remained in the background in a “frozen” state.
Is it safe to use the “Close All” button in the task menu?
Yes, it is safe from a data integrity point of view, but it is not always good for performance. Closing all windows once will not harm the phone. However, if you do this constantly every 5 minutes, you will interfere with the multitasking algorithms, which can lead to sluggish interface and reduced battery life due to constant rebooting of processes.
How to find out which application slows down your phone the most?
The best way is to use the built-in statistics tools. Go to Settings → Battery and see the list of applications sorted by energy consumption. Those apps that are at the top of the list, but which you rarely used, are most likely the reason for the high load on the processor and overheating of the device.
Do you need to install third-party antiviruses with the task manager function?
In most no cases. Built-in Google Play Protect and Android system mechanisms are quite effective. Third-party “antiviruses” that constantly hang in the background and scan running processes often themselves consume more resources than the potential threats they protect against. This can paradoxically slow down the smartphone.
