How to find out how much RAM on your Xiaomi phone: all working methods

RAM is one of the key parameters that affect smartphone performance: RAM volume determines how many applications can run simultaneously without hanging, how fast tasks are switched, and how smooth the interface works. Owners of Xiaomi, Redmi, and POCO often face the need to know the exact amount of RAM — whether it is to check the characteristics before buying a used device, optimize the system or diagnose problems.

Fortunately, there are several ways to check the amount of RAM on Xiaomi phones, from standard MIUI tools to third-party utilities and even engineering menus. In this article, we will analyze all the current methods, including nuances for different versions of firmware and models, learn how to distinguish real RAM from virtual RAM (if it is used), and also what to do if the phone shows less memory than the manufacturer stated.

Important: On some Xiaomi models, some RAM may be reserved by the system for background processes or functions like this. RAM-This is normal, but sometimes it leads to confusion. We'll explain how to recognize these cases.

1. Check RAM through standard MIUI settings

The easiest way to find out the amount of RAM is to look at the settings of the smartphone, which works on all Xiaomi, Redmi and POCO devices regardless of the version of MIUI (including MIUI 12/13/14 and HyperOS).

Instructions:

  1. Open the Settings app** (cog icon).
  2. Go to About Phone (sometimes called About Device).
  3. Slip on the phone specifications or all parameters.
  4. Find the line “RAM”** (or RAM) and it will show a physical volume, such as 6 GB or 8 GB.

Some firmware may have a slightly different path, such as HyperOS, where you need to go to Settings → About Phone → Basic Features. If you don't find a RAM item, try an alternative method in the next section.

Check the "Memory" section in the settings

Update MIUI to the latest version

Use a third-party application (see Section 3)

Restart your phone and try again.-->

Nuance: Some models (e.g., Xiaomi 12T or Redmi Note 11 Pro+) may display a +3GB or +5GB message next to the physical RAM. This is virtual memory created by an internal drive. Real RAM is the number to the + sign.

2. Quick check through the "Task Manager"

If you want to know not only the total amount of RAM, but also the current memory load, use the built-in task manager, which is suitable for diagnosing brakes or checking how much memory is occupied by running applications.

How to open it:

  1. Click on the “Recent Apps” button** (square or swipe up with a delay on gesture screens).
  2. At the bottom of the screen, find the words “Clean everything or Close everything” – next to the indicator of RAM usage (for example, 3.2 GB of 6 GB).
  3. Slip on this indicator to open up the extended statistics.

Here you'll see:

  • 📊 Total RAM (e.g. 6 GB).
  • 🔄 Real-time memory used.
  • 📉 Free memory and list of applications that consume the most resources.

💡

If the task manager displays less RAM than the manufacturer claims, this may be due to a system memory reservation or function. RAM-To see the actual volume, use the method in section 1 or 3.

On POCO and some Redmi, the path to the task manager may be different. If the swipe up doesn't open the application list, try holding the Home button (if you have one) or using the swipe up gesture with pause.

3. Third-party applications for detailed diagnostics

If standard methods don’t show full information or you want to get advanced data (such as memory type, frequency or kernel loading), use third-party utilities.We recommend proven applications that don’t require root rights and are safe for Xiaomi.

Top.-3 RAM-testing applications:

  • 🛠️ AIDA64 — Shows the full characteristics of the device, including the type of RAM (LPDDR4X, LPDDR5 And so on, the frequency and even the temperature of the chip.
  • 📱 CPU-Z — lightweight utility with a Memory tab, which displays the amount of RAM and information about the processor. Supports Russian language.
  • 🔍 DevCheck is a handy application with real-time memory usage visualization and detailed specifications.

How to use (in the example of AIDA64):

  1. Download the app from Google Play.
  2. Open it and provide access to device information (if requested).
  3. Go to the System or Memory section.
  4. Find the Total RAM string – this is the total amount of RAM.

Important: Some applications (e.g. AIDA64) may show RAM in megabytes (MB) rather than gigabytes (GB). To translate MB to GB, divide the number by 1024. For example, 6144 MB = 6 GB.

Checking through the engineering menu (for experienced users)

The Engineering Menu (#4636##) is a hidden Android tool that allows you to get low-level information about the device, including RAM data. This method is suitable for advanced users, as it requires caution (missteps can disrupt the phone).

How to open the engineering menu:

  1. Open the phone application** (keyboard set).
  2. Enter the code ##4636## (no spaces).
  3. Select Usage Statistics or Usage Statistics.
  4. Scroll down to the Memory section – here will be information about the common and available RAM.

⚠️

Warning: Do not change the settings in the engineering menu unless you know what they are intended for! This can cause your phone to malfunction, overheat or even fail.

On some Xiaomi models (e.g. Redmi 9 or POCO X3), the engineering menu may be blocked.

5. How to distinguish physical RAM from virtual

Many modern Xiaomi smartphones (e.g. Xiaomi 13, Redmi Note 12 Pro+) support RAM-extension technology, where part of the internal memory is used as additional RAM. This can be misleading: the phone shows, for example, 8+3 GB, but the real amount of RAM is only 8 GB.

How to recognize virtual memory:

    ⚠️

    Attention: Virtual memory is not the same as physical RAM in speed. It helps with multitasking, but it doesn't replace real RAM. If your phone is slowing down, turn it off. RAM-Extension in settings (Settings) → Advanced settings → Memory. → RAM-expansion).

    What is it? RAM-Extension and whether it is worth using?
    RAM-Extension (or Memory Extension) MIUI, It reserves a portion of the internal drive (usually 1-3 GB) to simulate RAM, which helps keep more applications in the background, but has drawbacks: ✅ Pros: you can run more applications at the same time, less often there are reboots of background processes. ❌ Cons: virtual memory works slower than physical, increases the wear of the internal drive, possible lags with intensive use. 🔹 Recommend: Turn off the feature if you notice hangings or if you have enough physical RAM (8GB or more).

    6.RAM verification via ADB (for developers)

    If you're familiar with the developer's tools, you can find out the amount of RAM you need through ADB (Android Debug Bridge), which is a method that's good for deep diagnostics or if other methods don't work.

    Instructions:

    1. Turn on USB debugging on your phone: Go to Settings → About Phone. Tap 7 times on MIUI Version to activate Developer Mode. Return to Settings → Additional → Developer. Activate USB Debugging.

    Connect your phone to your PC and open the command line (or terminal on Mac/Linux).

    adb shell cat /proc/meminfo | grep MemTotal

    MemTotal: 6144000 kB

    6144000 / 1048576 ≈ 5.86 GB

    This method shows the exact amount of physical RAM, without taking into account virtual memory, and it's useful if you suspect that the phone is showing incorrect data in the interface.

    💡

    ADB-cat /proc/meminfo — The most reliable way to find out the real amount of RAM, since the data is taken directly from the Android kernel, without intermediaries like MIUI.

    If you are just planning a purchase or want to check the data, here is the current table with the amount of RAM in popular devices Xiaomi, Redmi and POCO (as of 2026):

    ModelRAM volume (base version)Maximum configurationSupport RAM-expansion
    Xiaomi 148GB16GBYes (up to +8GB)
    Redmi Note 13 Pro+8GB12GBYes (up to +6GB)
    POCO X6 Pro8GB12GBYes (up to +5GB)
    Xiaomi 13T8GB12GBYes (up to +7GB)
    Redmi 124GB8GBYes (up to +3GB)

    ⚠️

    Note: Budget models (such as the Redmi A2 or POCO C50) can only have 2-3 GB of RAM installed. These devices do not do well in multitasking – keep this in mind when buying.

    Frequently Asked Questions (FAQ)

    🔹 Why the phone shows less RAM than claimed by the manufacturer?
    This is normal: part of the RAM is reserved by the system for Android and MIUI. For example, on Xiaomi with 6 GB of RAM available to the user can be 4.5-5 GB. Also check whether RAM-extension (virtual memory) is activated.
    🔹 Can I increase the amount of RAM on Xiaomi?
    Physically, no, because the memory is soldered to the motherboard. RAM-Extension in settings (Settings) → Memory. → RAM-Extension, but it's not equivalent to a real RAM replacement. Alternatively, buy a model with more memory.
    🔹 How to find out what type of RAM is installed in my Xiaomi (LPDDR4X, LPDDR5 etc.)?
    Use the AIDA64 or CPU-Z app. The Memory section will specify the type of memory, for example, flagship models (Xiaomi 13, 14) are equipped with LPDDR5, and budget models (Redmi 10A) are equipped with LPDDR4X.
    🔹 Why Task Manager Shows 100% RAM Boot Even When Your Phone Is Standing idle?
    Android and MIUI are optimized to maximize RAM: free memory is wasted. The system keeps in the background frequently used applications to run faster. That's okay if the phone doesn't slow down. You don't have to manually clean the memory!
    🔹 Can a RAM malfunction cause the phone to overheat or turn off?
    Yes, if the RAM module is damaged (for example, after a fall or moisture), this can lead to overheating, accidental reboots or blue death screens (BSOD). In such cases, contact the service center. You can not repair RAM yourself - you need to replace the motherboard.
