How to check RAM on Xiaomi: all ways

Have you bought a new Xiaomi smartphone but aren’t sure if the seller has honestly listed the amount of RAM? or want to know how much RAM is actually available to the system after the MIUI update? In this article, we’ll look at all the possible ways to check RAM on Xiaomi, Redmi and POCO devices – from standard settings to hidden engineering menus.

RAM directly affects multitasking and smartphone performance. For example, models with 4 GB of RAM can start to “brake” when running 10+ applications simultaneously, while 8-12 GB allows you to keep up to 20 programs in the background without hanging. But how to make sure that your Xiaomi is really equipped with the declared volume? Next, detailed instructions for all versions of MIUI (including MIUI 14 and HyperOS).

1.RAM check through Xiaomi's standard settings

The easiest way is to use the system’s built-in tools, and it’s suitable for all models, from the Redmi Note 4X (2017) to the flagship Xiaomi 14 Ultra (2026).

Open the Settings menu → About the phone. Depending on the firmware version, the path may be slightly different:

• 📱 MIUI 12–14 / HyperOS: Settings → The phone. → General characteristics
• 📱 Old versions (MIUI 11 and below: Settings → The phone. → Memory and storage
• 📱 For POCO: Settings → The phone. → Full specification

In the memory or RAM block, you will see two digits: total volume (for example, 8 GB) and available (for example, 5.2 GB). The difference arises from the fact that part of the RAM is reserved for the system and the GPU. On devices with Qualcomm chipsets (Snapdragon), it is usually “eaten” 1-1.5 GB, and on MediaTek (Helio/Dimensity) up to 2 GB.

⚠️ Note: Some models (e.g. Redmi) 9A) This menu only shows the total amount. To see the available memory, use the methods in the following sections.

2.Use of the Task Manager menu

This way you can not only find out the amount of RAM, but also see how much memory is occupied by running applications in real time, useful if the smartphone has started to “lag” and you want to identify “voracious” programs.

Instructions:

1. Click on the latest apps button (square or swipe up with a delay).
2. At the bottom of the screen, you'll see a panel that shows you how much RAM is used. Click on it.
3. Task Manager with detailed information will open: 📊 Total RAM: Total volume (e.g. 6 GB). 📉 Used: Current boot (e.g. 3.8 GB). 🔄 Free: available for new tasks (e.g. 2.2 GB).

On MIUI 14 and HyperOS, this menu also shows the average RAM load over the past 3 hours, which helps to assess the stability of the system. If the graph is constantly clogging 90%+ of memory, this is a sign that it is time to close the background applications or consider upgrading.

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

The hidden engineering menu allows you to get technical information directly from the Android system.This method works on all Xiaomi smartphones, but you need to be careful - do not change the settings if you are not sure about their purpose!

Steps:

1. Open the Phone app.
2. Enter the combination: ##4636### (some models may require ##225###).
3. Select the Phone Information tab.
4. Scroll down to the Memory block, and here's the MemTotal string. To translate it into gigabytes, divide it by 1,048,576. For example, MemTotal: 6291456 KB ≈ 6 GB.

Example of data from AIDA64 for Xiaomi 13 Pro:

Memory:




Total RAM: 12 GB (LPDDR5X)




Used RAM: 6.3 GB




Free RAM: 5.7 GB




Memory Clock: 3200 MHz




Bandwidth: 51.2 GB/s

These apps are also useful for diagnosing memory leaks when RAM is not released after programs are closed, for example, if 5 GB out of 8 is free after a restart and only 1 GB is free after an hour, this is a sign of a firmware or virus problem.

💡

If your free memory has decreased dramatically after the MIUI update, try resetting the cache to Settings → Memory → Clear the cache. This will free up to 1-2 GB of RAM without deleting data.

5. Check through ADB (for advanced users)

If you want the most accurate data, or you suspect that the seller has locked up some of the RAM (for example, on the Chinese versions of smartphones), you can use ADB (Android Debug Bridge), which requires a PC and minimal command line knowledge.

Instructions:

1. Enable USB Debugging in Settings → About Phone → MIUI Version (click 7 times, then go back to Settings → Additional → For Developers).
2. Connect your smartphone to your PC and open the command line (Windows) or Terminal (macOS/Linux).
3. Enter the command: adb shell cat /proc/meminfo
4. Find the MemTotal string – this is the total amount of RAM in kilobytes.

Example output for POCO F5 Pro (8 GB of RAM):

MemTotal:        8122348 kB




MemFree:         2100352 kB




MemAvailable:    3800124 kB




Buffers:          300124 kB

⚠️ Note: Some Chinese firmware (e.g., Xiaomi) 12S Ultra) the adb shell command may be limited. In this case, use the alternative command: adb shell dumpsys meminfo

6.How to know if the RAM on Xiaomi is not “cut off”?

Sometimes unscrupulous sellers or resellers software limit the amount of RAM to sell the smartphone as a model with less memory. For example, Xiaomi 11T Pro with 12 GB can be “cut” to 8 GB. How to check this?

Signs of "circumcised" memory:

• 🔍 B Settings → The phone displays a smaller volume than stated in the characteristics of the model.
• 📉 Apps like this AIDA64 The discrepancy between Total RAM and hardware specifications.
• 🔧 In the engineering menu (#4636##) MemTotal is less than expected.
• 🛠️ When connecting through ADB cat /proc/meminfo low-value.

If you suspect fraud, do the following:

1. Check the serial number of the device on the official Xiaomi website (Support → Check Warranty section).
2. Compare the data to the GSMArena database for your model.
3. If a discrepancy is confirmed, contact the service center with a check (if any) or return the goods to the seller.

💡

It is common in the Chinese market to downgrade smartphones before selling abroad. Always check RAM in a number of ways, especially when buying from hand.
