How to find out how much memory on Xiaomi: full analysis

Xiaomi smartphone owners often face a shortage of space to install new applications or slow down the system, which is directly related to filling internal storage and RAM. Understanding how space is allocated is key to optimizing the performance of your device. Modern shells MIUI and HyperOS hide some of the system files, which can mislead the user about the real volume.

In this article, we will discuss in detail all available ways to check the amount of memory on Xiaomi, Redmi and POCO smartphones. You will learn to distinguish between physical volume and available to the user, and also find tools for deep analysis of occupied space. Proper diagnosis will help avoid errors when buying a gadget or allow you to correctly plan the data cleanup.

Differences between operational and permanent memory

Before we get into the instructions, we need to be clear about the difference between the two main types of memory that you have installed in your smartphone: RAM is a temporary storage where the processor holds the data of applications running right now. Once you turn off the phone, all the data in RAM is erased.

In turn, persistent memory (ROM/PZU) is used for long-term storage of photos, videos, installed programs and system files, which is the volume most often interested in users when choosing a model, as it determines how much content will fit on the device.

💡

Note: advertised volume is always larger than the user’s available, as the Android system and MIUI shell take between 10 and 20 GB immediately after purchase.

Many people confuse these concepts by trying to “expand” photo space by closing background applications, which does not work. For proper resource management, it is important to know the specifications of your model.

Checking through standard smartphone settings

The easiest and safest way to find out the amount of memory on any Xiaomi device is to use the built-in settings interface, which does not require installing third-party software and gives a basic idea of the state of the drive.

For information, go to the Settings menu, then select About Phone. At the top of the screen, you will see the total amount of internal memory, for example, 256 GB. Clicking on this item, you will see a more detailed breakdown: how much is occupied by the system, applications and media, as well as how much is left free.

The same section often displays RAM, but not always explicitly. If you don't see RAM numbers on the About Home screen, try clicking multiple times in a row on the line with the MIUI or HyperOS version to activate the extended menu, or go to the Advanced Settings section (if you have one in your firmware version).

⚠️ Note: The values in the settings may differ from those declared by the manufacturer due to differences in number systems (1000 versus 1024 bytes) and.

Use of the "Security" application

Every Xiaomi smartphone has a Security app, which is a powerful resource monitoring tool that provides more visual information about what is eating away at your space, and is the first step in diagnosing if your phone is slow.

Run the app and select Cleanup. The system will automatically scan the device and show the percentage of memory occupancy. By clicking on Cleanup (or just going to the detailed browsing), you will see a breakdown by category: garbage, large files, rarely used applications.

Here, in the Acceleration section, you can see the current RAM load, the app will show how many megabytes or gigabytes of RAM is free at the moment, and suggest closing the background processes to free up resources.

Accurate diagnosis through the engineering menu

For users who need technical details that are not available in a normal interface, there is an engineering menu, which is a hidden part of the system, designed to test the hardware, and you can see the exact number of CPU cores, the modem version, and the actual amount of memory without rounding.

To get into this mode, open the Phone app and type ##6484##. If the code is right for your model, the CIT menu will open. Find Version Info or Memory on the list, and it will specify the exact specification of the memory chips.

Be careful when changing the settings in the engineering menu. Incorrect actions can lead to unstable operation of the radio module or recalibration of sensors. Your goal here is only to view information (View), not change parameters.

⚠️ Note: Some new HyperOS models may block the codes from entering the engineering menu for security reasons.

Third-party applications for detailed analysis

If built-in tools are not enough, specialized utilities from the Google Play Store come to the rescue, applications like CPU-Z, AIDA64 or DevCheck read data directly from memory controllers, providing comprehensive information.

After installing, for example, the CPU-Z, go to the Device or System tab. Here you will see the exact amount of RAM (for example, 7.8 GB of 8 GB of physical) and the type of memory used (LPDDR4X, LPDDR5). The Storage tab will show the real storage capacity and current wear (if the controller supports SMART).

These programs are useful not only for volume checks, but also for detecting fakes. If you bought a phone with your hands and the app shows that the physical volume is less than the stated settings, then the firmware was modified fraudulently.

💡

Third-party apps are the only way to see the type of RAM (DDR) and how often it works, which is important for assessing the performance of gaming smartphones.

Why is the amount available less than the stated

A common question users ask is, "Where did 30GB of 128GB go?" The answer lies in the storage architecture and operating system features. Manufacturers specify the full size of the chip, but some of it is reserved for the needs of the system.

First, the Android operating system itself and the graphics shell MIUI And secondly, there's a difference in numeral systems, where manufacturers use the decimal system (1 GB = 1 000 000 000 bytes, and computers are binary (1 GB = 1 024 Because of this, only about 85-90% from the declared volume.

• 📂 System partition: takes 10 to 15 GB depending on the Android version.
• 🔄 Recovery: A reserved area for resetting settings.
• 🛡️ Overflow protection: the system leaves a buffer for the cache to work properly.

Don't worry if the numbers don't match perfectly, it's a standard situation for all modern smartphones, regardless of brand, and the main thing is that the user has enough free space for a comfortable work.
