How to find RAM on the phone Xiaomi: all the ways

RAM is one of the key parameters of a smartphone that affects its performance. On Xiaomi, Redmi and POCO devices, the amount of RAM can range from 2 GB on budget models to 16 GB on flagships. Knowing the exact amount of memory will help assess the capabilities of the phone, optimize its operation or choose the right firmware.

Many users mistakenly confuse RAM with internal storage (ROM). If storage is responsible for files and applications, then RAM is used for multitasking and system speed. In this article, we will analyze all the available ways to check RAM on Xiaomi, from standard settings to hidden engineering menus.

Some methods require third-party applications, others work without the Internet, and we will also look at the nuances for different versions of MIUI and explain why some models display less memory than the manufacturer claimed.

1. Check through phone settings (the easiest way)

The fastest and most reliable method is to use the built-in MIUI tools. It does not require installing additional programs and works on all Xiaomi, Redmi and POCO models, including older firmware versions.

Instructions:

1. Open the Settings app (cog icon).
2. Go to the About Phone section (usually at the bottom of the menu).
3. Tap on Device Characteristics or General Information (the name may vary depending on the version of MIUI).
4. Find the RAM or RAM line, and the exact amount will be indicated here.

On the new MIUI 14+ versions, the path can look like this:

Settings → About the phone → All characteristics → Memory

⚠️ Note: Some models (e.g. Redmi Note 10 Pro) only display the total RAM, not the available RAM, in the specs. To see free memory, use the methods in the following sections.

Device model number | MIUI | RAM volume | Internal memory volume-->

2. Use of the Task Manager menu

MIUI has a built-in task manager that shows not only running applications, but also the current load of RAM, which is suitable for quick verification without deep settings.

How to open it:

1. Click on the recent apps button (square in the bottom navigation bar).
2. Swipe up the screen to open the extended menu.
3. At the top of the screen will appear a schedule of RAM use indicating the total and free volume.

Some firmware (e.g. MIUI 13) have a graph hidden to enable it:

Settings → Additional → Task Manager → Show memory usage

💡 Useful tip: If the graph shows a constant load of RAM at 90%+, This may indicate background activity of viruses or unoptimized applications. Check the phone with antivirus (e.g. Xiaomi Security).

Once a week |Only when it slows |Never |I don't know how to do it-->

3. Third-party applications for detailed diagnostics

If standard methods don't show the full information, you can use specialized utilities that not only display the amount of RAM, but also test its performance, detect errors and show detailed characteristics of iron.

Top.-3 Proven applications for Xiaomi:

• 📊 AIDA64 — Shows complete information about the iron, including the type of RAM (LPDDR4X, LPDDR5 etc.), frequency and kernel loading. Free version with advertising.
• 🔍 CPU-Z — It's a lightweight utility with a minimalist interface, displays the total amount of RAM and its use in real time.
• 🛠️ DevCheck is a modern analogue AIDA64 It shows how much memory is occupied by the system and how much by user applications.

🔹 How to use it AIDA64:

1. Install the app from Google Play.
2. Open the System section → Memory.
3. The RAM block will specify the total volume, type (e.g. LPDDR4X) and current boot.

⚠️ Note: Some applications (such as AnTuTu Benchmark) may show incorrect RAM on custom firmware. For accuracy, use only proven utilities from the list above.

Checking through the engineering menu (for experienced users)

The engineering menu (#4636##) contains hidden Android settings, including detailed memory information, which is suitable for advanced users, as it requires caution - incorrect actions can disrupt the system.

Step-by-step:

1. Open the Phone app.
2. Enter the combination: ##4636### (some models may require ##36446337###).
3. Select the phone information (or Usage statistics).
4. Scroll down to the Memory block – here will be the total amount of RAM and its current use.

📌 On models with a MediaTek processor (e.g. Redmi Note 11), the engineering menu may be missing or require root rights.

⚠️ Warning: Do not change the settings in the engineering menu unless you are sure of their purpose! for example, disabling the Background process limit can lead to automatic phone restarts.

💡

If the engineering menu doesn’t open, try using the MTK Engineering Mode app (for MediaTek) or Qualcomm Mode (for Snapdragon).

5. ADB commands for advanced users

If you need to get RAM data for debugging or testing, you can use ADB (Android Debug Bridge), which requires connecting the phone to a computer and basic command line knowledge.

Instructions:

1. Turn on USB Debugging on your phone: Settings → About Phone → MIUI Version (Tap 7 times) → Return to Settings → Additional → For Developers → Debugging on USB
2. Connect your phone to your PC and open the command line (or Terminal on Mac/Linux).
3. Enter the command to check the total memory: adb shell cat /proc/meminfo | grep MemTotal The result will be in kilobytes (divide by 1024 to get megabytes).
4. To check your free memory, use: adb shell cat /proc/meminfo | grep MemFree

🔹 Example of inference:

MemTotal: 12000000 kB (≈12 GB)


MemFree: 3000000 kB (≈3 GB free)

⚠️ Attention: Teams ADB may not work on some custom firmware (e.g. LineageOS or Pixel Experience) if the kernel is modified.

💡

ADB is the most accurate way to test RAM, but it requires preparation, and use it if other methods fail or if you need data to debug.

6. How to find out the type and frequency of RAM

Memory is not the only important parameter: Type (LPDDR4X, LPDDR5) and frequency (e.g., 2133 MHz) are the factors that determine the processing speed, and you can learn these characteristics through specialized applications.

📋 Comparison of RAM Types on Xiaomi:

🔍 How to check the type of RAM:

• 📱 In the annex AIDA64 Go to the System → Memory. → Type of RAM.
• 🖥️ On PC through ADB Enter adb shell cat /proc/cpuinfo | grep "Hardware" Then search for your CPU specifications on the internet (e.g., Snapdragon). 8 Gen 2 supportive LPDDR5X).

💡 Useful advice: If your phone supports LPDDR5, But in benchmarks, it shows low performance, check the power saving settings. MIUI may limit the frequency of RAM.

7.Why does the phone show less RAM than claimed?

Many Xiaomi users are faced with a situation where the characteristics indicate, for example, 8 GB of RAM, and the system shows only 6-7 GB. This is not a marriage and not a fraud – this is how the Android architecture works.

🔹 Main causes:

• 🖼️ Reservations for GPU: On phones with powerful GPUs (such as Black Shark or GPUs). POCO F4 GT) Up to 2 GB of RAM can be attached to video memory.
• 🤖 System processes: Android reserves some memory for the kernel and services. MIUI 14. ~1GB.
• 🔄 Dynamic distribution: On some models (e.g. Xiaomi) 12S Ultra uses Memory Fusion technology, which temporarily “borrows” up to 3 GB from internal memory (ROM) RAM-wise.

⚠️ Warning: If the phone shows significantly less memory than it should (e.g., 4GB instead of 8GB), this could be a sign:

• Malfunctions of the motherboard (especially after falls or moisture).
• Installed custom firmware with incorrect core settings.
• Hardware restriction (for example, some Chinese versions of Redmi artificially lock part of the RAM).

8. Frequent errors in the RAM test

When trying to find out how much RAM, users often make mistakes that lead to wrong conclusions, and let's take a look at the most common ones.

🚫 Typical misconceptions:

• 📱 "Free memory = Total": Many people confuse the current free RAM (e.g., 2 GB) with total RAM (e.g., 8 GB). Remember: Android always reserves some memory for system needs.
• 🔄 "After cleaning RAM, the phone is faster: Manually closing applications through Task Manager does not speed up, and often even slows down, as the system has to re-load data.
• 🔍 "Apps show different RAM: This is normal — different utilities may or may not take into account redundant memory. AIDA64.

🔧 How to avoid mistakes:

1. Use at least two methods of verification (e.g. settings + AIDA64).
2. Check the data with the official characteristics of your model on the Xiaomi website.
3. If the data is very different, check the phone for viruses or reset the settings.

💡

Don’t trust benchmarks (like AnTuTu) to test RAM – they often show overvalued or undervalued values due to firmware optimizations.
