How to check RAM (RAM) on Xiaomi: all the ways from settings to ADB

RAM is the brain of your Xiaomi smartphone, which is responsible for app speed and multitasking. If your phone starts to slow down, shut down programs spontaneously, or overheat, the first diagnostic is to check the state of RAM. But how do you know how much memory is in the device, and how much is free right now?

In this article, we’ll look at all the available ways, from standard MIUI settings to hidden engineering menus and ADB commands. You’ll learn not only how to view the volume of RAM, but also how to check its load in real time, identify “gluttonous” applications and even test memory for errors. Instructions are relevant for all models Xiaomi, Redmi and POCO based on MIUI 12-14 and HyperOS.

Important: Some methods require developer rights or PC connectivity. If you're a beginner, start with the simple (sections 1-3) and then move on to the advanced ones.

1. Check RAM through standard MIUI settings

The fastest and safest way is to use the system’s built-in tools.It doesn’t require third-party apps to be installed and works on all Xiaomi smartphones regardless of the firmware version.

Open the Settings → About the phone menu. Here you will see basic information about the device, including the line “RAM”. For example, on the Xiaomi 13 Pro, it will say: 12 GB. This is the physical amount of RAM installed in the smartphone — it does not change over time.

But this method only shows the total volume, not the current load, to see how much memory is being used right now:

1. Go to Settings → Applications → Application Management.
2. Click on the three dots in the upper right corner and select Memory Use.
3. A graph will open with data on free / occupied RAM and a list of applications that consume the most resources.

💡

If you see an unknown process with high RAM consumption (e.g. com.android.abc) in the app list, check your phone for viruses using Google Play Protect or Malwarebytes.

Note that MIUI aggressively manages memory, so even when you close applications, the system can keep them in the background for quick start-up. This is normal behavior, but if the free RAM is less than 20%, it is worth optimizing the boot (for this in section 5).

2.Use the Security Menu for RAM monitoring

The Security app in MIUI is not only an antivirus, but also a powerful diagnostic tool, and it provides detailed statistics on RAM usage, including background processes and cache.

How to open it:

• 🔍 Find the Security icon (or Security in Global Firmware) on your desktop).
• 📊 Go to the Optimization tab (or Boost).
• 📈 Click on Memory – here you will see a pie chart with the distribution of RAM by category: System processes (cannot be closed) User Applications (can be cleared) Cash (temporary data)

At the bottom of the screen, there's a Clean button, it will force the background applications to close, and don't overuse it, because frequent RAM cleaning can actually slow down, because the system will have to re-download the data the next time it opens the applications.

The Security → Memory menu also has a usage log for the past 24 hours, which will help identify applications that eat up memory in the background (such as Facebook, TikTok or instant messengers).

3 Hidden codes for diagnostics of RAM (Engineer Mode)

For advanced users, Xiaomi has an engineering menu that checks not only the amount of RAM, but also its speed, delays and errors, a method that works on most models, but may not be available in some global firmware.

Instructions:

1. Open the phone app and enter the code: ##4636##
2. In the menu that opens, select Device Information (or Device Information).
3. Scroll down to the Memory block, and you will find data on Total RAM and Available RAM.

For more detailed diagnosis, use the code:

##284##

It will open the RAM test. Don't interrupt the process, it can cause the system to crash. The test takes 1-2 minutes and, when completed, will show PASS (OK) or FAIL (Error).

On some models (for example, POCO F5 or Redmi Note 12 Pro+) is available advanced diagnostic mode through the code:

##36446337##

It will open the MTK Engineer Mode menu (for devices running MediaTek chips), where you can run the RAM stress test in the Hardware Testing → Memory section.

4. View RAM through ADB (for power users)

If you want the most accurate RAM status data, including details on each process, use ADB (Android Debug Bridge), which requires connecting your smartphone to your PC and enabling debugging over USB.

Step-by-step:

1. Enable Developer Mode: Go to Settings → About Phone. Click 7 times on MIUI Version. Go back to Settings → Additional → For Developers and activate Debugging over USB.

Connect the phone to the PC and confirm the debugging permission.

adb shell dumpsys meminfo

This command will provide complete information about RAM usage, including:

• Total volume (MemTotal)
• Free Memory (MemFree)
• List of processes with indication of consumption (Pss, Rss)

For simplified output, use:

adb shell cat /proc/meminfo

This command will show the key parameters in the format:

MemTotal:       12129748 kB


MemFree:         3129748 kB




Buffers:          512974 kB

If you need data about a particular application, use:

adb shell dumpsys meminfo com.android.chrome

(Replace com.android.chrome with the desired application package).

5. Third-party RAM monitoring applications

If standard MIUI tools don’t suit you, you can use apps from Google Play, which offer advanced features like real-time graphics, overload notifications, cache cleanups, and even performance tests.

Top.-3 apps:

How to use DevCheck:

• 📥 Install the app from Google Play.
• 📱 Open it and go to the Hardware tab.
• 📊 In the Memory block you will see: Total RAM — Total Available – Free Used memory – Occupied Cached memory – Cached data

💡

RAM monitoring apps are useful, but don't manually clear memory too often. Android is optimized to control RAM automatically, and forced cleaning can reduce performance.

For testing. RAM errors can be used MemTest86 (However, this method is risky and can lead to loss of warranty, so we recommend it only to experienced users.

6. How to increase the amount of RAM on Xiaomi (Virtual Memory)

Starting with MIUI 12.5 and HyperOS, Xiaomi has added the option to expand RAM with an internal drive, not by physically increasing RAM, but by creating a virtual swap file that helps with memory shortages.

How to turn on:

1. Go to Settings → Additional → Memory Extension (or Memory Extension)
2. Select the virtual RAM volume: 1 GB, 2 GB or 3 GB (maximum depends on the model).
3. Click Apply and restart the phone.

Important:

• ⚠️ Virtual RAM It does not replace physical – it only smoothes peak loads.
• ⚠️ The function takes space from internal storage (for example, 3 GB of virtual storage). RAM = minus 3GB on the disk).
• ⚠️ On weak smartphones (for example, Redmi). 9A) This can reduce performance due to slow internal memory.

The effectiveness of virtual RAM depends on the model:

If after turning on the virtual RAM phone began to work slower, turn off the function and clear the cache in the Security menu.

7. Optimizing the use of RAM: 5 practical tips

Even if you have enough RAM, inefficient use of it can lead to lags. Here are proven ways to optimize:

• 🚫 Limit autoload: Go to Settings → Annexes → Application management → Autorun. Turn off autorun for unnecessary applications (especially instant messengers and social networks).
• 🔄 Clean the cache regularly: In the Security Menu → Press Deep Cleanse once every 1-2 weeks (no more often!).
• 📱 Use the "Lite" versions of the apps: Replace Facebook with Facebook Lite, Messenger with Messenger Lite. Use YouTube Vanced (if available) or NewPipe to watch videos.
• 🔋 Follow the background processes: In Settings → Battery → Battery use check which apps are active in the background. Turn off background activity for unnecessary programs.
• 🛠️ Update the firmware: In new versions MIUI HyperOS optimized memory management. Check the updates in Settings → The phone. → Updating the system.

💡

If you play heavy games (like Genshin Impact or Call of Duty Mobile), close all background apps through the recent task menu before launching, which will free up to 30% of RAM.

If after optimization the brake problem remains, check the phone for viruses or perform a factory reset (don’t forget to make a backup!).
