How to See Xiaomi Memory: A Complete Guide

Owners of Xiaomi, Redmi and POCO smartphones sooner or later face a lack of space or a slowdown. Understanding how space is distributed on your device is the first step to optimizing. Modern MIUI and HyperOS shells offer many tools for analysis, but they are scattered across different menus, which can confuse the inexperienced user.

In this article, we will go into detail all the ways to know the state of storage: you will learn to distinguish RAM from embedded ROM, find hidden files that take up gigabytes, and understand why the system shows only numbers, and the real volume seems smaller.

Proper management of the device’s resources prolongs its life and ensures stable application operation. Do not ignore overflow signals, as this can lead to unpredictable failures in the Android operating system.

Differences between operational and embedded memory

Before we get to settings, we need to be clear about the difference between the two main types of memory that are often confused: RAM is a fast storage that temporarily hosts data from running applications. It is the amount of RAM that determines multitasking: how many programs can run simultaneously without rebooting.

Embedded memory (ROM or Storage) is a permanent storage for your operating system, installed programs, photos, videos and music. When you download a file or take a picture, it is stored here. Read and write speeds are lower than RAM, but the data does not disappear after you turn off the phone.

In Xiaomi devices, these metrics can be checked in one place, but they need to be interpreted differently. Lack of RAM leads to the closure of background applications, while a lack of ROM blocks the installation of new programs and the creation of photos.

Memory check through standard Android settings

The easiest and most reliable way to find out the current state of storage is to use the regular menu of the system, which does not require installing third-party software and gives the most accurate data about what the space is occupied.

Find the Settings icon on your desktop or in the notification curtain. In the list that opens, you need to scroll down to the section that may be called About Phone or Advanced Settings depending on the version of the MIUI shell or HyperOS.

Inside the About Phone menu, you'll see a line called Memory or Warehouse, and if you click on it, it will open up detailed statistics, and it shows the total volume, the available space, and the approximate categorization of apps, images, video, audio, and so on.

⚠️ Note: Do not delete system files from folders with names that you do not know the meaning of, which can lead to incorrect interface or loss of important phone functions.

If you're using a microSD card, the same menu will show you your status, and it will show you how much space is occupied on the external media and how much is free, and it's convenient for carrying heavy media files to unload the main drive.

Using the Security Application for Cleaning

Xiaomi has built a powerful built-in tool called Security into its devices, which is not just an antivirus, but also a comprehensive memory manager, and run the app through a label with a shield on your desktop.

In the main menu, select Clean up. The system will automatically scan the device for junk files, app cache and residual data. After scanning, you will see a Clean up button that will delete secure temporary files.

For a deeper analysis, click on the Deep Clean icon, where the tool will prompt you to delete large files, duplicate photos, unused apps and APK installation packages. This is the most efficient way to quickly free up a few gigabytes.

In the Application Management section inside the same tool, you can see which apps take up the most space, and it often turns out that instant messengers like Telegram or WhatsApp have grown to unimaginable sizes because of the accumulated cache.

Why does memory fill up again?
Once cleaned, the space can quickly run out due to background processes: Messengers automatically upload new media files, and browsers create a cache of visited pages, and regular cleaning is the only way to keep things under control.

Engineering menus and hidden codes for diagnostics

For advanced users, there is access to hidden parts of the system through special USSD-This method allows you to access technical information that is hidden from the average user in the standard settings interface.

Open the Phone app and enter the code ##6484##. The CIT menu will appear on the screen, where you can check not only the memory, but also the operation of all sensors, screens and communication modules.

For direct memory check, the engineering menu often uses the code ##4636##. Going to the Storage Information section, you will see a detailed table with the total size, space used and free space in bytes.

Entered codes for diagnosis:




1. ##6484## - CIT Testing Menu




2. ##4636### - Android Test Menu




3. *#06# - IMEI check (basic information)

These codes are safe to use if you're just browsing through the information, but changing the settings in the engineering menu without understanding their purpose can disrupt the radio module or other critical components.

Memory analysis by third-party applications

Xiaomi’s regular tools are good, but sometimes a more detailed picture is required. Third-party file managers and disk analyzers can show the folder structure in the form of a visual map, which makes it easier to find β€œheavy” files.

A popular solution is Files by Google or DiskUsage, which scans the internal storage and plots the size of the rectangles to match the size of the files, and you can see what takes up the most space: Instagram cache, downloaded TV shows or forgotten archives.

You should also look at the Clean Master app or its counterparts, although Xiaomi’s built-in cleaner often does just as well.The main advantage of third-party software is the ability to sort files by date of change, which helps you find old downloads.

Use the visual disk analyzers to find forgotten files in the Download folder, often storing app installers that are no longer needed.

Optimization and freeing up space on Xiaomi

Once you've figured out that your memory is full, you have to act. The first step is always to clear the cache of heavy applications. Social media and instant messengers have a habit of accumulating gigabytes of temporary data.

Go to Settings β†’ Applications β†’ All apps. Select a voracious app (like Telegram) and click Memory β†’ Clear cache. It is important not to confuse it with the Clean Anything button that will delete your logins and correspondence.

The second efficient method is to move media files to the cloud: Google Photos, Yandex.Disk or MI Cloud let you store photos and videos online, freeing up local space. Set up automatic synchronization so you don't have to think about backups manually.

⚠️ Warning: Before clearing the messenger data, make sure to back up the correspondence if it is important. Once "only" is cleaned, it will be impossible to restore the dialogue without a backup.

It is also recommended to remove unused applications. MIUI has a feature called "Mode lite", which allows you to temporarily disable system applications, but for third-party software it is better to use complete removal.

Frequent questions about memory on Xiaomi

Why is the memory less than the specified characteristics?
Part of the internal memory is always reserved for the Android operating system and shell. MIUI/HyperOS. In addition, manufacturers use a binary number system, where 1 GB is equal to 1024 MB, and mark memory by decimal system (1000 MB) which creates a visual difference.
Can I increase memory on Xiaomi with a memory card?
You can’t physically increase the amount of internal storage, but many models support microSD cards, which can be used as portable storage for photos and videos, and in some cases as an extension of internal memory for installing applications.
What is a swap file and why is it needed?
Swap (or virtual memory) is a technology that allows you to use part of the permanent memory (ROM) as an additional RAM (RAM). This is useful for gaming, but can reduce the speed of the drive when you use it actively.
How to check if the memory card is fake?
Use applications like Fake Test or H2testw (on PCs) that record the test data to the entire map and read it back, and if the data is corrupted, then the actual card volume is less than the claimed one.

Regular memory checks and deleting junk files are the best way to prevent your Xiaomi smartphone from slowing down: Do not bring the storage to full capacity (red zone), leave at least 10-15% free space for the system to work properly.
