How to find out how much RAM on your Xiaomi phone: 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 in budget models to 16 GB in flagships. Knowing the exact amount of memory helps assess the capabilities of the gadget, select the optimal settings or diagnose the causes of brakes.

In this article, we'll look at all the ways you can test RAM, from standard settings to hidden engineering menus, how different methods are for different versions of MIUI, which apps give you the most accurate data, and what to do if your phone doesn't show real memory, and why sometimes 6GB of RAM is listed in specs, and the system only sees 5.5GB.

1. Verification through standard MIUI settings

The easiest way is to use the built-in MIUI shell tools. It is suitable for all Xiaomi models, including the Redmi Note 12, POCO X5 and even the outdated Redmi 4X. The main advantage of the method is that you do not need to install third-party applications.

Instructions:

1. Open the Settings app (cog icon).
2. Go to About Phone (sometimes called About Device).
3. Tap on All Characteristics or Memory and Storage (depending on the MIUI version).
4. Find RAM. This will show you a physical volume, like 8 GB.

⚠️ Note: On some devices (e.g. Redmi) 9A) This menu displays only the available memory, not the full volume. To see real data, use alternative methods from the following sections.

Device model number|Version MIUI|The volume of RAM|ROM (internal memory)|Battery status-->

2. Use of the Diagnostics menu (hidden section)

MIUI firmware has a hidden engineering menu that displays technical data, including the exact amount of RAM, which works on 90% of Xiaomi devices, but may not be available on some custom firmware.

How to open it:

1. Launch the phone (calling) application.
2. Enter the combination: ##4636##
3. In the menu that opens, select Phone Information.
4. Scroll down to the Memory block – here will be a Total RAM string with an exact volume in megabytes (e.g., 6144 MB = 6 GB).

⚠️ Note: Not all combinations work on new versions MIUI 14+. If the code doesn’t work, try alternative methods or update the firmware.

Redmi Note Series Series Series|POCO F/X series|Xiaomi 11/12/13|Redmi 9/10 series|Another model-->

3. Third-party applications for detailed diagnostics

Applications like AIDA64, CPU-Z or DevCheck not only display the amount of RAM, but also provide data on its type (LPDDR4X, LPDDR5), frequency and load in real time.

Top.-3 check-in:

• 📊 AIDA64 — Total shows up RAM, Available RAM And even the temperature of the chip. The free version is pretty functional.
• 🔍 CPU-Z — The Memory tab contains data about the type of RAM and its manufacturer (for example, Samsung or Micron).
• 🛠️ DevCheck is a minimalist interface with a focus on hardware specifications, including Used RAM and cached RAM.

⚠️ Note: On some Xiaomi devices, apps may show less RAM than the specs indicate. This is normal: some memory is reserved for the GPU (GPU) and system needs. POCO X3 Pro with 6 GB of RAM available ~5.3GB.

4. Check through ADB (for advanced users)

If you want the most accurate data, including information about each RAM module, use ADB (Android Debug Bridge), which requires connecting the phone to a PC and basic command line knowledge.

Instructions:

1. Turn on Developer Mode on your phone: go to Settings → About Phone and tap the MIUI version 7 times.
2. Return to Settings → Additional → For developers and activate Debugging over USB.
3. Connect your phone to your PC, open the terminal and type in: adb shell cat /proc/meminfo | grep MemTotal The answer will be in the format: MemTotal: 6144000 kB (6 GB).

For detailed information about each RAM bank, use the command:

adb shell dumpsys meminfo

In the conclusion, find the MemTotal and MemFree block.

💡

If the adb command doesn’t work, install Google’s Platform Tools or use Minimal ADB and Fastboot.

5. How to find out RAM on a switched-off phone (by model)

If the phone doesn't turn on or you're just planning to buy, you can tell the RAM volume by model.

1. Find a sticker on the box or under the battery (on removable batteries), usually it shows specifications, such as 6GB+128GB.
2. Check the model in the official Xiaomi catalog: 🌐 Go to mi.com. 🔎 Type the name of the model in the search (for example, Redmi Note 12 Pro).+ 5G). 📋 In the Specifications section, find the line RAM.

GSMArena

DeviceSpecs

⚠️ Note: On AliExpress and other marketplaces, sellers sometimes indicate the wrong amount of RAM. Always check the data with the official Xiaomi website or check through the official Xiaomi website. IMEI (services like IMEI.info).

6.Why does the phone show less RAM than the specifications?

Many Xiaomi users are faced with a situation where the settings display, for example, 5.8 GB instead of the declared 6 GB. This is not a defect – this is how the Android architecture works.

Main reasons:

• 🖥️ Reservations for GPU: The video processor uses a portion of RAM for textures and rendering. On Snapdragon chips, it's 512-1024 MB.
• 🤖 Systemic requirements MIUI: sheath ~300–500 MB for background processes.
• 📉 Marketing rounding: 6GB is actually 6,144MB, but the system shows a binary value (6GB) = 6300 MB in binary system).
• 🔄 Dynamic distribution: on some devices (e.g, POCO F4 GT) RAM is divided between CPU and GPU real-time.

💡 How do you check the actual volume? Use the command ADB section 4 or annex AIDA64 — They show the physical amount of memory, not the amount available to the user.

💡

If the difference between the declared and actual RAM volume exceeds 10% (for example, 6 GB → 5 GB), this may indicate a hardware defect or an unofficial firmware.

7. Optimizing RAM on Xiaomi: Cleanup Tips

Knowing the amount of RAM is useful not only for diagnostics, but also for optimizing the phone. If the device is slowing down, try:

• 🧹 Background clearing: in MIUI There is a built-in tool - go to Settings → Annexes → Clean and press Clear Memory.
• ❄️ Disable animations: activate Developer Mode and install Windows Animation, Transition Animation and Animator Duration at 0,5x.
• 🚫 Limitation of background processes: C Settings → Battery → Power mode select Saving charge – this will reduce RAM consumption.
• 🔄 Reboot: Xiaomi with 4-6 GB of RAM is recommended to reboot every 2-3 days to release cache.

⚠️ Attention: Forced cleaning of RAM through Settings → Memory. → Cleaning can impair performance. Android is optimized to manage memory automatically - manual cleaning resets cache, making apps run longer.

💡

To find out which applications consume RAM the most, go to Settings → Apps → Application Management → Memory and sort by usage.
