On Xiaomi, Redmi, and POCO smartphones, background apps can consume battery power and RAM invisibly. If the phone is slowing down or quickly draining, the first thing to do is check which programs are currently running. In this article, weβll take a look at all the available methods, from standard MIUI tools to hidden features for power users.
It's important to understand that simply closing all applications doesn't always solve the problem. Some system processes automatically restart, while others (like messengers) can run in the background by default, and we'll show you how to not only see the active processes, but also manage them correctly.
Method 1: Through the recent application panel
The fastest and most intuitive method is to use the multitasking bar, which works on all versions of MIUI (12 to 14) and does not require any additional settings.
- π± Click the square button in the bottom navigation bar (or swipe up from the bottom edge of the screen and hold for a second).
- π You will see a list of recent apps β here you will see all the programs you have recently launched.
- π At the top of the screen you will see information about the load of RAM (for example, "Using 3.2 GB of 6 GB").
Note that this list shows not only the active applications, but also the completed applications that the system stores in the cache for quick launch. To close the program completely, swipe the card up or down (depending on the model).

If the multitasking panel doesn't open, check your gesture settings in Settings β Display β Full-screen display. Another type of navigation may be enabled.
Method 2: Using the Security Menu
MIUI has a built-in tool to monitor application activity, called Security, and you can see not only the programs that are running, but also their impact on performance.
- Open the Security app (the shield icon).
- Go to Accelerate (or Optimize in older versions).
- Click on Memory Management β here you will see a list of active processes indicating the consumption of RAM.
- To close unnecessary applications, click Clean (or Optimize).
This menu also includes an auto-clean feature that automatically closes the background when you lock the screen. To turn it on, activate the Auto-clean switch when you lock it.
| Type of application | RAM consumption | Can I close it? |
|---|---|---|
| System processes (e.g. com.android.systemui) | 100-500 MB | β No (forced closure will cause failure) |
| Messengers (Telegram, WhatsApp) | 50β300 MB | β Yes (but notifications will come with a delay) |
| Games (PUBG Mobile, Genshin Impact) | 500 MB-2 GB | β Yes (recommended to close after the game) |
| Service Utilities (Mi Fit, Google Play Services) | 30β200 MB | β οΈ Partially (can restart automatically) |
Method 3: through the developer settings
For advanced users, you can view all processes, including system processes, through the developer menu.
Find the settings β The phone.|7 times press the version MIUI|Back to Settings β Additionally. β For developers|Activate the switch at the top-->
After the regime is activated:
- Go to Settings β Additional β For developers.
- Find the Debugging section and select the Process List.
- All active processes, including hidden system processes (e.g. mediaserver or android.process.acore) will be displayed here.
β οΈ Warning: Shutting down system processes manually can cause a phone to run unstable or restart. Do this only if you know exactly what the process is for.
You can also see a PID (process identifier) and a UID (user identifier) in this menu, which is useful for diagnosing problems through ADB.
Method 4: Using third-party applications
If standard MIUI tools are not enough, you can install specialized utilities from Google Play, which provide advanced information about running processes, including:
- π Detailed consumption statistics CPU, RAM and batteries.
- π The ability to sort processes according to different criteria (for example, by work time).
- β‘ Functions of automatic closing of unnecessary applications on schedule.
Top.-3 monitoring:
- Greenify optimizes the work of background processes without manual closure.
- Developer Quick Settings β Adds the process control panel to the notification curtain.
- Simple System Monitor β shows real-time activity with graphs.
β οΈ Note: Some applications (such as Greenify) require root rights to work properly.

Method 5: via ADB (for power users)
If you want to get full control of the processes, you can use ADB (Android Debug Bridge), which is suitable for diagnosis or debugging, but requires connecting the phone to a computer.
- Install ADB on your PC (download Platform Tools from Googleβs website).
- Connect your phone via USB and allow debugging (enable it in Settings β For developers).
- Open the command prompt and type: adb shell ps-A This command will output all the processes running on the device.
- To close a particular process, use: adb shell kill [PID] (replace [PID] with a real identifier from the list).
With ADB, you can also get information about resource consumption for a particular application, such as a command to:
adb shell dumpsys meminfo com.android.chromeIt will show how much RAM Google Chrome uses.
π‘
Use ADB only if you understand the consequences. Incorrect commands can cause system failure or data loss.
What to do if your phone slows down even after the app is closed?
If the performance hasn't improved after cleaning the background processes, the problem may be deeper.
- π Battery condition: worn-out battery causes lags.Check battery health in Settings β Battery β Battery status.
- ποΈ Memory occupancy: If the internal storage is less than 10%, the system starts to slow down.
- π Updates: outdated version MIUI It may contain errors. Check for updates in Settings β The phone. β Updating the system.
- π οΈ Cache reset: go to Settings β Memory. β Clean and select Clear Cache.
If nothing helps, try resetting to factory settings (don't forget to back up!).
- Open Settings β About Phone β Backup and Reset.
- Select Settings Reset.
- Confirm the action and wait for the reboot.
