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

Why check RAM on Xiaomi and what it gives

RAM is a key component that affects the speed of your Xiaomi, Redmi or POCO. When apps start to slow down and the system produces errors like “App is closed due to memory shortages,” the first thing to check is the state of RAM. But how do you do it correctly?

Unlike internal memory (ROM), which stores files, RAM is responsible for multitasking: the more free it is, the faster applications are switched. On new models Xiaomi 13/14 or Redmi Note 12 with 8-12 GB of RAM problems are less common, but on budget devices (for example, POCO M5 with 4 GB) every megabyte on the account. In this article, 5 proven ways to find out the amount of RAM, its use and even hidden data that do not show the standard menus.

Important: RAM data may vary depending on the version MIUI (global, Chinese, EU-So, if your Xiaomi is running on HyperOS, the new shell after that. MIUI 14), some paths on the menu will be different - we will specify alternatives.

Method 1: Standard MIUI/HyperOS settings

The easiest method is to use the built-in system tools. It is suitable for all models, from Redmi 9A to Xiaomi 14 Ultra, and does not require the installation of third-party applications.

Instructions:

1. Open Settings (the gear icon on the main screen).
2. Go to About Phone (HyperOS – Device Information).
3. Slip on the item Characteristics of the device or All parameters (depending on the firmware version).
4. Find the RAM line – the total volume will be listed here (for example, 6 GB or 8 GB).

Method limitation: here you will see only the total amount of RAM, not the current load. To see how much memory is used right now, read the next section.

💡

On some models (e.g. Xiaomi 12T), the path may be different: Settings → System → Advanced Settings → Memory.

How to watch the use of RAM in real time

For this:

1. Open the Settings → Applications.
2. At the top of the screen, select Working (or Active) tab.
3. At the top, a graph will appear that says RAM usage and download percentage (e.g., 3.2GB of 6GB (53%)).

Method 2: Hidden Menu of Engineering Settings (#4636##)

This menu is designed for developers and testers, but is available on all Xiaomi without root rights, and you can see detailed statistics on the use of RAM, including hidden system processes.

How to open it:

1. Launch the phone (calling) application.
2. Enter the combination: ##4636### (some firmware may not work – see the alternative below).
3. Select the item Phone information (in English firmware).
4. Scroll down to the Memory block - here it is displayed: 📊 Total RAM — total. 🔄 Used RAM — currently occupied. ⚡ Free RAM — freely. 🗑️ Cached RAM — cached (may be released).

If ##4636### is not working,

• 🔧 Try the alternative code: ##225## (shows memory and battery information).
• 📱 On HyperOS, the engineering menu can be blocked – use method 3 or 4.

Method 3: The Security App from Xiaomi

In the firmware MIUI/HyperOS There is a built-in Security app (shield icon) that not only clears the cache, but also shows detailed statistics on memory.

Step-by-step:

1. Open the Security app (if it is not on the home screen, search through the system search).
2. Go to the Optimization or Acceleration tab (name depends on the version of MIUI).
3. At the top of the screen, you’ll see a circular graph labeled RAM Use and an exact value (e.g., 4.1 GB/8 GB).
4. Slip on the schedule – will open an extended statistics with a list of applications that consume the most memory.

The advantage of this method is that you can close all background processes in one tap, freeing up RAM. However, be careful - forced closure of system applications (for example, com.miui.home) can cause failures.

🔹 Close unnecessary applications manually

🔹 Clear the cache through "Security" → Cleanup"

🔹 Reboot the phone (releases "hang" processes)

🔹 Check for viruses (some malware consume RAM in the background)

Method 4: Third-party applications (CPU-Z, AIDA64, DevCheck)

If the built-in MIUI tools seem inadequate, use specialized utilities that show not only the amount of RAM, but also the type of memory (LPDDR4X, LPDDR5), the frequency, and data about the processor and other components.

Top.-3 check-in:

Example of CPU-Z use:

1. Install and open the application.
2. Go to the Memory tab.
3. Note the lines: Total RAM is total. Used RAM is occupied. Type is type of memory (e.g. LPDDR4X). Frequency is frequency (e.g. 1866 MHz).

💡

Applications like AIDA64 show redundant memory, the part of the RAM that the system gives to a graphics processing unit (GPU) or camera modules. For example, on the Xiaomi 13 Pro of 12 GB of RAM, up to 2 GB can be reserved for the Adreno 740 GPU.

Method 5: Through ADB (for advanced users)

If you want the most accurate data or you are developing applications for Xiaomi, use Android Debug Bridge (ADB), which requires connecting the phone to a PC, but gives access to hidden settings.

What you need:

• 🖥️ Computer with installed ADB-driver.
• 📱 Included Debugging by USB on the phone (Settings) → The phone. → Version. MIUI — Tap 7 times, then go back to Settings → Additionally. → For developers).
• 🔌 USB-cable (preferably original).

Commands for RAM verification:

adb shell cat /proc/meminfo

This team will provide detailed information where:

• MemTotal is the total amount of RAM in kilobytes.
• MemFree is a free memory.
• Buffers and Cached are cached data.

For convenience, convert the values from KB to GB by dividing by 1,048,576. For example, MemTotal: 6250000 KB ≈ 5.96 GB.

💡

If the adb shell cat /proc/meminfo command returns an error, try root accessing (on the unlocked bootloader) first or use an alternative command:

adb shell dumpsys meminfo

What to do if the RAM is constantly loaded at 100%

If your Xiaomi is slowing down and RAM is always loaded to the end, the problem may be:

• 🤖 Background processes – some applications (such as Facebook or TikTok) consume RAM even when folded.
• 🦠 Viruses or malware – Advertising Trojans or mining bots can load the system.
• 🔄 Failures MIUI — After updates, system services (for example, miui.analytics) sometimes “hang” after updates).
• 📱 Lack of memory – on devices with 3-4 GB of RAM, modern games (Genshin Impact, Call of Duty Mobile) require optimization.

Decisions:

1. Cache Cleanup: Settings → Applications → Select the App → Clear the Cache.
2. Disable Autostart: Settings → Applications → Autostart Management.
3. Reset to factory settings (extreme case): Settings → System → Reset settings.
4. Firmware update: Sometimes memory bugs are fixed in newer versions of MIUI/HyperOS.

💡

On Xiaomi with virtual memory (RAM Expansion), part of the internal drive is used as an addition to RAM. To turn it off: Settings → Advanced Settings → Memory → Virtual memory.

FAQ: Frequent questions about RAM on Xiaomi

💡

If you buy used Xiaomi, check RAM through CPU-Z – some sellers indicate in the ad the amount of memory “before expansion” (for example, write 8 GB, although actually 6 GB + 2 GB virtual).
