Xiaomi smartphone owners, including Redmi and POCO, often face the need to clarify the specifications of their device. Especially relevant is the question of how to find out the RAM Xiaomi when the device is bought from hand or requires accurate information to install resource-intensive applications. Many users confuse internal storage for files with a fast buffer for running processes.
It's easy to understand this, given where to look in the operating system menu. Modern MIUI and HyperOS shells provide fairly transparent access to system information, but the paths to this data may differ from firmware to firmware, and we'll look at all the options, from standard settings to hidden engineering codes.
Understanding the amount of RAM available is critical to estimating the potential performance of a gadget, and it's this parameter that determines how many applications can run simultaneously in the background without having to reboot. Let's go through each diagnostic method in detail.
Checking through standard system settings
The easiest and safest way to get specifications is to go to the regular menu of your smartphone. Current versions of the MIUI shell usually hide the path to data in the About Phone section. You need to open Settings, scroll down the list and select About Phone, which displays basic model and processor information.
However, in some interface modifications, the memory capacity is not specified on the first screen, in which case you should click on the line with the name of the processor or the version of the system several times in a row, this action activates a hidden menu or an extended card of the device, where RAM and ROM parameters are detailed.
It is worth considering that manufacturers often indicate total memory, but some of it is reserved by the system. Therefore, the actual available volume may be less than stated in the specifications.
💡
When viewing the characteristics in the settings, pay attention to the type of memory (LPDDR4X or LPDDR5), as this directly affects the speed of the interface.
Use of the Engineering Menu for Detailed Diagnostics
To get deeper into the technical data, you can use the engineering menu that is built into the firmware of each Xiaomi device, which allows you to see not only the volume, but also the current loading of memory chips in real time. To enter this mode, open the Phone application and type the combination # # # #64663##.
Once you enter the code, you will see a list of test features, you will need to find a section related to Version or Hardware Info. Depending on the smartphone model, the item names may vary, and you will see information about all the hardware components, including the type of RAM installed and its manufacturer.
⚠️ Note: Be careful when navigating the engineering menu.Do not run hardware tests (such as screen or speaker tests) unless you plan to do them, as this may temporarily change the display or sound settings.
The engineering menu is especially useful if the standard settings don’t show the full picture or if you suspect that the device has replaced components, which is often found when buying used equipment, where unscrupulous sellers can programmatically change the displayed data, but hide it in deep system logs is more difficult.
What if the code doesn't work?
Third-party characterization applications
When built-in tools are scarce, specialized tools come to the rescue from the Google Play store, the leader in this area is the CPU-Z application, which provides comprehensive information about the hardware. Once installed, run the program and go to the Device or System tab.
Here you'll see the exact amount of memory you've installed, the type of memory you've got, and the current frequency, and apps like this read data directly from the memory controller, so it's almost impossible for them to lie, and that's the best way to test the performance of a smartphone when you buy it from your hands.
- 📱 CPU-Z — Classical tool for detailed analysis of processor and memory.
- 📊 AIDA64 — powerful combine, showing the temperature, load and volume of all modules.
- 🚀 DevCheck – utility with a convenient interface that displays information about the system in real time.
Using third-party software also allows you to track how much memory is occupied by the system right now, which is an important parameter, since heavy shells MIUI can consume a significant amount of RAM immediately after turning on, which affects the speed of launching games.
Checking through a computer and ADB-team
For advanced users who are used to working with the command line, there is a method of connecting to a smartphone via ADB (Android Debug Bridge), which provides the most accurate data, since it requests it directly from the kernel of the system, bypassing the graphical interface. First, you need to include debugging over USB in the menu for developers.
Connect your smartphone to your computer with a cable and open the terminal on your PC. Enter a command to list all processes and memory usage. The system will give you a detailed report where the string will be responsible for the total amount of physical memory.
adb shell cat /proc/meminfo | grep MemTotalThe result will be presented in kilobytes. Dividing the resulting number by 1024 twice, you get volume in gigabytes, which is ideal for testing devices on which standard menus can be blocked or modified.
⚠️ Attention: To work with ADB You need to install the device drivers on your computer, and without them, the computer won't see the smartphone in debugging mode, and the command won't execute.
Using console commands also allows you to see how memory is distributed between different processes, which is useful for finding memory-eating applications that slow down the system.
☑️ Preparation for verification via PC
Comparison of characteristics of different Xiaomi models
Understanding how much storage you need comes with the experience of using different models: The Redmi Note series budget devices often come with 4 or 6GB of RAM, while the Xiaomi and POCO F series flagships boast 8, 12 and even 16GB.
The difference in volume directly affects multitasking. If you used to keep open dozens of tabs in the browser and several messengers, the minimum comfortable volume today can be considered 6 GB. 3D-It is preferable to choose devices with a stock.
| Smartphone model | Volume of RAM (GB) | Type of memory | Recommendation |
|---|---|---|---|
| Redmi 12C | 3 / 4 | LPDDR4X | Basic objectives |
| POCO X5 | 6 / 8 | LPDDR4X | Games and multimedia |
| Xiaomi 13 | 8 / 12 | LPDDR5 | Flagship productivity |
| POCO F5 Pro | 8 / 12 | LPDDR5 | heavy gaming |
When choosing a new device, always pay attention not only to the volume number, but also to the type of memory. LPDDR5 standard works much faster than its predecessor LPDDR4X, which allows smoother interface and faster application launch.
💡
For comfortable work in 2026-2026, the best choice will be a smartphone with 8 GB of RAM type LPDDR4X or higher.
Virtual memory expansion: myth or reality?
Recent versions of MIUI and HyperOS have introduced a virtual memory extension feature, which takes a portion of the internal storage (ROM) and uses it as an add-on to RAM, and can be found by Settings → Advanced Settings → Expanded Memory.
The technology allows you to add 2 to 5 GB of virtual volume, but it is worth noting that the speed of the internal flash drive is much lower than the speed of a real RAM. Therefore, the performance gains will only be noticeable in scenarios where the physical memory is completely full.
Enabling this feature may be useful for devices with a small amount of memory (3-4 GB), but on powerful smartphones with 8 or more GB, the effect will be minimal.
If you decide to change the extension settings, the device will require a reboot. After you turn on the About menu, you will see an updated value for the total amount of RAM available.
