Why it is important to control the use of RAM on Xiaomi
RAM is your smartphone’s desktop, where active applications and processes are temporarily stored. When RAM is full, Xiaomi starts to slow down: apps open for a long time, video hangs, and games crash, especially for budget models (Redmi 9A, POCO M3) with 2-4 GB of memory or flagships (Xiaomi 13 Ultra, Mix Fold 3), where background processes eat up to 50% of resources.
Unlike iPhones or Samsungs, Xiaomi’s MIUI/HyperOS smartphones aggressively cache data to speed up app re-launching. This is useful, but sometimes leads to a false sense of “memory shortage” where the system shows 80-90% RAM loading, when in fact 30-40% cache.
In this article you will find:
- 🔍 Methods to check RAM loading through built-in tools MIUI HyperOS.
- 📊 Process Analysis: How to distinguish system services from malware.
- ⚡ Optimizing memory without harming performance.
- ⚠️ Dangerous myths that spoil a smartphone (for example, “cleaning RAM manually speeds up work»).
Method 1: Built-in memory monitor in MIUI/HyperOS
The fastest way is to use the standard Task Manager, which is on all Xiaomi smartphones regardless of the firmware version, which shows not only the overall load of RAM, but also the distribution by application.
Instructions:
- Open the settings (cog icon on the desktop).
- Go to About Phone → Memory (or Storage in HyperOS).
- Slip on the RAM tab (in some versions - RAM).
- The system will display a usage schedule and a list of active processes sorted by consumption.
What can you see?
- 📈 Download schedule: peak loads (for example, when starting a game or rendering a video).
- 🔄 Cache processes: applications that have been recently used (can be closed without harm).
- ⚠️ Suspicious services: If there are unknown names on the list (e.g. com.android.XXX), it could be a virus.
Total RAM load (normal – 60-80% with active use)
Applications with consumption >100 MB (possible "gluttonous" games or social networks)
System processes with abnormal load (e.g., mediaserver eats 300MB)
Background tasks that can be turned off-->
Note: in HyperOS (new firmware for Xiaomi 14, Redmi K70, etc.), the memory monitor interface is changed - the data is displayed in real time with division into active, cached and system processes.
Method 2: Deployed statistics through "For developers"
If a standard monitor isn't enough, turn on the developer mode, which gives you access to detailed statistics on RAM usage, including hidden system processes, which is useful for diagnosing "glitch" or finding memory leaks.
How to turn on:
- Go to Settings. → The phone.
- Tap 7 times on the MIUI version (or HyperOS build number).
- Return to the main settings menu and a new section for developers will appear.
- Open it and find the items: Process statistics (showns detailed RAM consumption by each application). Memory → Average RAM usage (graphic over the last 3-12 hours).
Advantages of this method:
- 📊 All processes, including system processes (e.g., surfaceflinger or zygote) are visible).
- 🕒 Long-term usage history (useful for finding “gluttonous” apps).
- 🔧 Ability to force background tasks to stop (but be careful – it can disrupt the system!).
💡
If you see a high-consumption com.miui.daemon or a high-consumption com.xiaomi.market in the process list, that’s OK, these are MIUI system services.
Attention: not all processes can be stopped manually, such as closing system_server It will lead to a reboot of the smartphone.
Method 3: Third-party applications for RAM analysis
Xiaomi’s built-in tools don’t always show the full picture. For in-depth analysis, use third-party utilities that visualize memory consumption, identify leaks, and suggest optimization.
Top.-3 apps:
| Annex | Functions | Pluses | Cons |
|---|---|---|---|
| DevCheck | Monitoring RAM, CPU, storage | Detailed statistics, real-time graphs | Advertising in the free version |
| Simple System Monitor | Process tracking, temperature, network | Light, no background, open source | Minimalist interface |
| CPU Monitor | Analysis of RAM + processor loading | Overheating/overload notifications | Paid for full functionality |
How to use (as in DevCheck):
- Install the app from Google Play.
- Open the Memory tab.
- Note: Used RAM: how much memory is used right now. Cached: data for quick access (you can clean it without consequences), Free: free memory (if less than 10%, you should optimize).
Slip through any process to see details (such as which package ran it).

Warning: Some “optimizers” (like Clean Master) aggressively clear RAM, which slows down due to constant app reboots. Xiaomi manages memory more efficiently!
Method 4: ADB commands for advanced users
If you need the most accurate data (for example, to debug or search for memory leaks in custom firmware), use ADB, a tool for interacting with Android through your computer.
What can be done through ADB:
- 📋 Get a full process dump with detailed RAM consumption.
- 🔍 Find memory leaks that are not visible in standard tools.
- ⚡ Forced shutdown of system services (for experienced users!).
Instructions:
- Install ADB Tools on your PC.
- Enable USB Debugging on Xiaomi (Settings → Developer).
- Connect your phone to your computer and execute the commands: adb shell dumpsys meminfo or for a specific application (e.g. Facebook): adb shell dumpsys meminfo com.facebook.katana
Example of the output of the dumpsys meminfo command:
MemTotal: 5820344 kB
MemFree: 842136 kB
Buffers: 123456 kB
Cached: 1204567 kB
...
Applications Memory Usage (in KB):
com.miui.home: 180456
com.android.chrome: 304567
com.facebook.orca: 456789What do the key parameters in ADB output mean?
⚠️ Note: Do not remove processes through ADB, If you're not sure what they're doing, for example, killing com.android.phone will cause you to lose your network!
Method 5: System Logs for Finding Memory Leaks
If your Xiaomi suddenly starts to “brake” and RAM is clogged for no apparent reason, the problem can be in memory leaks — when the application does not free up resources after closing.
How to get logs:
- Install the Logcat Extreme or MatLog app from Google Play.
- Start log recording (start button).
- Replay the problem (for example, open/close the app after which the phone is lagging).
- Stop recording and find the keywords in the logs: Out of memory (OOM) — Memory leak signal is a clear leak. GC_FOR_ALLOC — Frequent garbage collections (a sign of overloading).
An example of a problem from the log:
05-20 14:30:45.123 E/AndroidRuntime: FATAL EXCEPTION: main
Process: com.example.app, PID: 12345
java.lang.OutOfMemoryError: Failed to allocate a 104857612-byte allocation...If you find such errors, try:
- 🔄 Reinstall the problem application.
- 📥 Update it to the latest version.
- 🚫 Limit background activity in settings (Settings) → Annexes → Permits → Auto-start).
How to optimize the use of RAM without harming Xiaomi
Many users believe that cleaning the RAM speeds up the smartphone, but in fact Android and MIUI manage memory more effectively than manual actions.
What really works:
- 🛑 Limit background activity: Go to Settings → Annexes → Application management. Select an application (e.g. TikTok or Instagram) → Limit background activity.
- 🗑️ Clean the cache regularly: In Settings → Warehouse → Clean up, click Clear cache. For individual applications: Settings → Annexes → [Select the application] → Clear the cache.
- 🔄 Update the firmware: In new versions MIUI/HyperOS Optimized memory manager (for example, HyperOS added a “smart cache»).
- ❌ Remove Unnecessary Applications: Even unused programs can run background processes (e.g., Clean Master or Unused Programs). UC Browser).
What can't be done:
- ❌ Use the “boosters of RAM” from Google Play – they only interfere with the system.
- ❌ Manually kill processes through ADB For developers without understanding the consequences.
- ❌ Disabling system services (such as Google Play Services) will disrupt your smartphone.
💡
The optimal RAM load on Xiaomi is 60-80%. If it is free, less than 10%, it is worth optimizing. But manually cleaning the memory (through “boosters”) often leads to the opposite effect – applications have to be rebooted from scratch, which wastes more resources.
