How to find out the amount of RAM on the Xiaomi phone: all the ways

RAM is one of the key parameters of a smartphone that determines its performance. On Xiaomi, Redmi and POCO phones, the amount of RAM affects the number of applications running simultaneously, the speed of switching between tasks and the overall smoothness of the interface. But how do you know how much RAM is installed in your device? Especially if you bought a phone with your hands or do not remember its exact characteristics.

In this article, we will look at all the available ways to check RAM, from standard settings to hidden engineering menus, how to determine the amount of memory without additional applications, what nuances are in different Xiaomi models, and what to do if the system shows incorrect data, and we will also explain why sometimes the actual amount of RAM can differ from the stated manufacturer.

1.RAM check through Xiaomi's standard settings

The easiest way is to use the built-in MIUI tools. This method works on all modern Xiaomi smartphones, including the Redmi Note 12, POCO X5 and Mi 11. You do not need to install third-party apps or obtain root rights.

Instructions:

1. Open the Settings app (cog icon).
2. Go to About Phone (usually at the bottom of the list).
3. Slip on the item All characteristics or characteristics of the device.
4. Find the RAM line, and it will show the exact amount in gigabytes.

On some firmware, the path may be slightly different. For example, on older versions of MIUI (up to 12th), you need to go to Settings → About Phone → General Information. If you have a POCO shell with a POCO Launcher, the menu may look different, but the logic remains the same.

Open "Settings"|Find "On the Phone"|Select "All characteristics"|Check the line "Rapid memory"-->

⚠️ Note: Some budget models (e.g. Redmi) 9A or POCO C31) The characteristics may display total memory capacity rather than the separation between RAM and ROM. In this case, use alternative methods from the following sections.

2.Use of the application "Security" (Security)

Xiaomi’s proprietary Security app not only protects the device from viruses, but also provides detailed information about the system, which provides not only the amount of RAM, but also the current memory load, which is useful for diagnosing “brakes”.

How to check:

• 📱 Open the Security app (shield icon with tick).
• 🔍 Go to the Optimization or Acceleration tab (name depends on version) MIUI).
• 📊 At the top of the screen, you'll see a memory usage graph.
• 📋 A window will open with detailed information, where the total capacity of RAM and current use will be indicated.

The advantage of this method is that it displays real memory available with system reserves in mind. For example, if your Xiaomi 12T has 8 GB of RAM, then about 6.5-7 GB can be available for applications - the rest is reserved for the system.

4GB or less |6GB|8GB|12GB or more-->

3. Check through the engineering menu (code ##4636##)

The hidden engineering menu allows you to get technical information about the device, including RAM data.This method works on most Android smartphones, but on Xiaomi may be limited due to the security policy of MIUI.

Instructions:

1. Open the Phone app.
2. Enter the combination: ##4636## (no spaces).
3. In the menu that opens, select Phone Information or Usage Statistics.
4. Scroll down to the Memory block - the total amount of RAM will be indicated here.

On newer models (Xiaomi 13, Redmi Note 12 Pro+), this code may not work due to locking.

adb shell cat /proc/meminfo | grep MemTotal

This command must be entered through ADB (Developer Tool) and will output the exact amount of memory in kilobytes. For example, the MemTotal string: 6166604 kB stands for ~6 GB of RAM.

Third-party applications for RAM verification

If standard methods fail, you can use specialized utilities that not only show the amount of memory, but also provide additional information about the processor, battery and other components.

Top.-3 apps:

• 🛠️ AIDA64 — Shows the full specification of the device, including the type of RAM (LPDDR4X, LPDDR5) frequency.
• 📊 CPU-Z — displays the amount of RAM on the Memory tab, as well as information about the processor and graphics.
• 🔍 DevCheck is a user-friendly interface with a division into "Hardware" (hardware) and "System" (system).

Example of AIDA64:

1. Install the app from Google Play.
2. Open it and go to the System section.
3. Select Memory – here will be the total amount of RAM and current usage.
4. For detailed information, tap on RAM - data on memory type and frequency will open.

⚠️ Note: Some applications (such as AnTuTu Benchmark) may show incorrect RAM on smartphones with Memory Extension technology. AIDA64.

5. Check through Fastboot mode (for advanced users)

If your Xiaomi is not turned on or stuck on the logo, but you need to know the amount of RAM, you can use Fastboot mode. ADB/Fastboot.

Step-by-step:

1. Turn off the phone.
2. Press the Power + Volume Down button before the Fastboot logo appears.
3. Connect the device to the PC via USB.
4. Open the command line (Windows) or terminal (macOS/Linux) and type:

fastboot getvar all

In the output, find the line ram: – here will be the amount of memory in megabytes (for example, ram: 0x200000000 means 8 GB).

For convenience, you can use the MiFlash utility (the official tool from Xiaomi), which automatically recognizes the model and characteristics of the device in Fastboot mode.

💡

If you frequently work with Fastboot, save the command fastboot getvar all > info.txt – this will write all the device data into a text file for further analysis.

6.How to find out RAM on a switched off Xiaomi phone

If the smartphone is discharged or not turned on, but you need to know the amount of RAM, there are several ways:

• 📦 Phone box – the sticker usually shows the main characteristics, including RAM.
• 🔧 Serial number – it is possible to determine the model and find the specifications on the official website of Xiaomi.
• 💻 PC software – if the phone is determined by a computer (for example, in Device Manager), you can use utilities like XiaomiTool V2.

Example of serial number determination:

1. Find the serial number on the box or under the battery (if removable).
2. Go to mi.com/verify.
3. Enter the serial number – the system will show the model and basic characteristics.

On Xiaomi phones with a non-removable battery, the serial number can be found on the phone. SIM-under the back cover or under the back cover (if removed).

7.Why the actual amount of RAM may differ from the stated

Many users notice that the settings display less memory than indicated in the specs. For example, the Redmi Note 11 Pro with 8 GB of RAM shows only 7.2 GB. This is normal and due to several factors:

• 🖥️ System Reserves – Android and MIUI reserve some memory for the kernel and drivers.
• 📱 Memory Extension technology – some models (for example, Xiaomi 12) use virtual memory, which adds 1-3 GB of physical RAM from the drive.
• 🔄 Binary vs decimal score – manufacturers specify volume in gibbytes (1 GiB) = 1024 MiB), and the system can show in gigabytes (1 GB = 1000 MB).

For example, if the characteristics indicate 6 GB of RAM, then:

• Physically available: ~5.5–5.8 GB (after system needs are deducted).
• Virtual memory: can be displayed as 8-9 GB (if Memory Extension is activated).

💡

Xiaomi phones with Memory Extension technology (such as the POCO F4 GT) can display the total amount of physical and virtual memory in the settings. To see real RAM, use AIDA64 or the engineering menu.

8. Frequent mistakes and how to avoid them

When checking the amount of RAM, users often encounter inaccurate data or misunderstandings.

• 🔄 Confusion between RAM and ROM – both parameters are specified in the characteristics of the phone (for example, 6/128 The first number is RAM, the second is internal memory.
• 📱 Use of inappropriate applications – some benchmarks (e.g. Geekbench) show only available memory, not total storage capacity.
• 🔧 Ignoring virtual memory – on new Xiaomi models, part of the drive can be used as RAM, which distorts the real numbers.

To avoid mistakes:

1. Always check data from multiple sources (settings + AIDA64 + engineering menu).
2. If the RAM volume seems suspiciously large (for example, 12 GB on a budget model), check if Memory Extension is activated.
3. On phones with custom firmware (for example, LineageOS), RAM data may not be displayed correctly - in this case, focus on the physical characteristics of the model.

⚠️ Note: Some Xiaomi models (e.g. Redmi) 10C) The total amount of memory (RAM) can be displayed in the settings + ROM) instead of separate ROM. Use an app to avoid confusion. AIDA64 Or check the box from the phone.
