Modern smartphones database Android are powerful computing systems capable of performing many tasks simultaneously. However, it is multitasking that often causes the device to slow down when the user notices slowdowns or rapid battery drain. Understanding exactly which active processes are currently consuming the resources of your gadget is the first step towards proper system optimization. Without this information, the fight against lags turns into guesswork.
Unlike desktop operating systems, the mobile platform hides detailed information about the operation of the kernel and background services from the average user. Google developers have deliberately limited access to this data to prevent inexperienced users from accidentally deleting critical system components. However, there are several legal and safe ways to look “under the hood” of your smartphone and see the real picture of what is happening.
In this article we will examine in detail all the available methods: from built-in engineering menus to advanced PC tools. You will learn to distinguish system services from parasitic software, understand why the phone heats up when idle, and will be able to make an informed decision about what exactly is worth leaving in memory and what needs to be mercilessly stopped.
Using developer mode for monitoring
The easiest and most accessible way to see the list of running applications is to activate a special mode in the system settings. By default, this feature is hidden to protect the user from accidental changes to critical parameters. To activate, you need to go to the section Settings → About phone and find the item Build number. By clicking on it 7 times in a row, you will receive a notification that you have become a developer.
After enabling the mode, a new section will appear in the main settings menu For developers. This is where the key to memory management lies. You need to find a subsection, which may be called Running applications, Services or Active Services depending on the version Android and shell manufacturer. This displays a list of all processes that are currently occupying random access memory (RAM).
The interface of this section usually shows the name of the process, how long it has been running and the amount of memory occupied. This allows you to instantly identify "heavyweights" that should not be running in the background. For example, you may find that a browser or social network is consuming hundreds of megabytes even if you haven't opened it for several hours.
⚠️ Warning: Do not terminate processes whose names you do not understand. Forced stop of system services (for example
android.systemor display drivers) can lead to an emergency reboot of the device or unstable operation of the sensor.
It is worth noting that in modern versions of Android (starting from 10 and higher), Google is gradually cutting down the functionality of this menu, believing that the system itself copes better with memory management. Therefore, on new smartphones this section may be hidden deeper or contain less detail than on older devices.
If you cannot find the "Running applications" section, use the search in settings by entering the word "services" or "memory".
Battery usage analysis as an indicator of processes
Often the user does not need to see the exact name of each system stream, it is enough to understand which application loads the processor the most and consumes energy. Battery consumption statistics are an excellent indirect tool for identifying hidden background processes. Go to Settings → Battery → Battery usageto see a detailed report.
Here you will see a list of applications sorted by the percentage of energy consumption over the last 24 hours or since the last full charge. If you see an application that you have not used, but it is at the top of the list, it means that it is executing some kind of background application. This could be synchronization, collection of analytics, or, in the worst case, cryptocurrency mining by malware. process. This could be synchronization, analytics collection, or, in the worst case, cryptocurrency mining with malware.
By clicking on a specific application in this list, you will receive more detailed information: how long it worked in active mode (screen on), and how long in the background. A high percentage of background time without your activity is a sure sign that the app needs to be limited or removed.
- 🔋 High consumption in the background: a sign of unoptimized code or malicious activity.
- 📉 Sharp consumption spike: may indicate a hung process that does not go to sleep.
- 🛡️ System services: usually consume little but constantly (Google Play Services, Phone).
This method is especially useful for identifying “vampires” that do not appear in the list of running applications, but actively wake up the processor to perform their tasks. The Android system tries to aggregate such processes under the name of the main application, which simplifies diagnostics for the average user.
Advanced monitoring via ADB and computer
For those who want to get the most complete and technically accurate information about processes, the best solution is to use USB debugging and utilities ADB (Android Debug Bridge). This method requires connecting the smartphone to the computer and installing drivers, but it provides access to data that is hidden even in the developer menu.
After connecting the device and authorizing debugging on the phone screen, you can run a command in the computer's terminal, which will display a detailed list of all running processes with their PIDs (identifiers) and resource consumption. This is a professional level of diagnostics used by engineers and advanced enthusiasts.
adb shell top -m 20This command will show the top 20 processes that load the processor in real time. You will see not only the package name, but also the CPU percentage, memory usage and process status (Running, Sleeping, Zombie). If you see a process with a name containing a random set of characters that loads the system by 50-80%, it is almost certainly a virus or a miner.
There is also a more detailed command for viewing exactly the services and linking them to users:
adb shell dumpsys activity servicesThe output of this command can be very voluminous, but it contains comprehensive information about which service belongs to which application and in what state it is located. This is an indispensable tool when the phone slows down, but it is visually unclear who the culprit is.
⚠️ Attention: ADB commands give the rights to deeply interfere with the system. Incorrect use of commands like
killorstopcan lead to data loss or the need to flash the device.
How to install ADB on Windows?
Download the Platform Tools package from the official Android developers website. Unpack the archive into a convenient folder. Open a command prompt in this folder (Shift + Right mouse button → Open Powershell window here) and enter the command to test the connection: adb devices. If the device is detected, you are ready to work.
Third-party utilities for system analysis
If you don’t want to mess around with the command line, and the built-in tools are not enough, specialized applications from the store come to the rescue. Google Play. There are many tools that visualize process data in an easy-to-use graphical interface. However, the choice of such software must be approached with extreme caution.
Most popular “cleaners” and “accelerators” are themselves parasitic processes that constantly hang in the memory and show intrusive advertising. Instead of real help, they only create the appearance of activity. useful utilities should be lightweight and provide honest statistics without unnecessary embellishment.
One reliable option is to use system monitors, which simply display data rather than attempt to aggressively clean up memory. They allow you to see the CPU core load graph, temperature and list of active applications in real time.
| Utility name | Access type | Presence of ROOT | Main function |
|---|---|---|---|
| CPU-Z | Custom | Not required | Monitoring frequencies and CPU load |
| SystemPanel 2 | Custom | Not required | History of launching applications and services |
| Simple System Monitor | Advanced | Desirable | Detailed overview of processes and networks |
| GSam Battery Monitor | Custom | Not required | Deep analysis of the causes of discharge |
When installing such apps, be sure to check the permissions they request. If a simple process monitor requires access to contacts, microphone or geolocation, this is an alarming signal. Uninstall such an application immediately, as it may collect your personal data.
The best third-party tool is the one that runs minimally in the background and does not require constant notifications about “garbage found.”
Differences between system processes and user processes
When you finally saw the list of running tasks, a logical question arises: which of these can be touched and what cannot? The list is usually a mixture of clear application names and strange system designations. Understanding this difference is critical to device security.
User processes usually have friendly names that match the names of installed apps (for example, com.telegram.messenger or com.spotify.music). Ikh mozhno smelo zakryvat, esli oni ne nuzhny v dannyy moment. System processes are often named by acronyms or technical terms related to the operation of the Linux kernel on which Android is based.
Critical system services run the phone, screen, communications and sensors. These include system_server, android.hardwarevarious demons (daemons). Completion of such processes will lead to the fact that the phone will stop responding to presses, the sound will disappear, or the device will go into an eternal reboot (bootloop).
- 🤖 system_server: the main process that manages all other services. Do not touch!
- 📡 rild: responsible for the operation of the radio module and cellular communications. Stopping will deprive the network.
- 🖥️ surfaceflinger: responsible for rendering the interface. A failure will cause a black screen.
If you see a process with a name that is Googled as a virus or miner, but it is disguised as a system one (for example, it is called com.android.update, but is located in the user’s folder), this is a reason to immediately scan with an antivirus. Real system processes are always located in protected sections of the system.
☑️ Checking a suspicious process
Optimization and management of background activity
Just looking at the processes is not enough - you need to be able to manage them. Modern Android has built-in mechanisms for limiting background activity, which work more efficiently than any manual closures. Instead of constantly “killing” applications, it is better to configure the rules for their behavior.
Go to the settings of a specific application (Settings → Applications → [Select application] → Battery) and select the restriction mode. The option Limited or Austerity will prevent the application from running in the background when you are not using it. This is ideal for apps that you rarely use, but which like to hang around in memory.
For games and heavy applications, you can use the "Sleep" function or force stop after use. It is also useful to disable autorun for unnecessary apps. Many manufacturers (Xiaomi, Samsung, Huawei) add their own startup managers, where you can use checkboxes to prohibit the start of certain services when you turn on the phone.
⚠️ Attention: Energy saving settings may differ on different firmwares. What is called “Background Limitation” on pure Android may be called “Activity Control” in the MIUI shell. Always check the official information for your model, as interfaces change with each update.
Regularly rebooting your smartphone is also an effective method of clearing the memory of accumulated errors and “zombie processes” that are not unloaded correctly. It is enough to do this once a week to keep the system in good shape without using third-party software.
Why do applications start again after closing?
Many services are interconnected. Closing one may cause the other to restart via interprocess communication (IPC) mechanisms. In addition, some applications use system alarms (alarm clocks) to revive themselves at a given time.
Is it possible to delete system processes via ADB?
Technically, this is possible if you have root access or special access rights, but it is strictly not recommended. Removing a critical system process (for example, PackageManager or Settings) will make the phone inoperable, and a complete flashing of the device via the computer will be required.
Why does the phone show many running processes even though everything is closed?
This is normal Android behavior. The system pre-loads frequently used applications into RAM so that they open instantly. Empty RAM is bad RAM. Processes are unloaded automatically when memory is needed for a new task.
How to find out which process is heating up the phone?
Use the command adb shell top and look at the CPU load. Processes with high CPU usage over long periods of time generate a lot of heat. Also check the battery statistics, the leading application in terms of energy consumption is often visible there.
Is it harmful to constantly close applications from the multitasking menu?
Yes, it can be harmful. Forced closing forces the system to spend more resources on restarting the application from scratch, which drains the battery more than if the application was simply hanging in a minimized state in RAM.
What is the "android.process.media" process?
This is a system service responsible for working with media files, data storage, and access to the file system for applications. It is necessary for the gallery to work correctly, download files and save data. Stopping it will lead to errors when saving photos or downloading documents.
