Xiaomi’s current smartphones, which run MIUI shells or the new HyperOS, have powerful functionality that requires significant resources to work sustainably. One of the most common problems users face after a year or two of active use of the gadget is a lack of free space in internal memory. The device starts to work slower, applications fly out, and the system insists on freeing up space.
Many Redmi and POCO owners don’t know where to find detailed information about what precious storage is occupied. Standard icons often hide details, and standard notifications may not be clear to beginners. Understanding the structure of the file system and the ability to correctly interpret data about occupied space is a key skill to extend the life of your smartphone.
In this article, we will take a look at all the ways to check memory, from standard settings to hidden engineering menus, learn how to distinguish system files from user data, understand why memory is eaten by itself, and learn how to safely clean your gadget without losing important information.
Use of the standard "Security" application
The fastest and most affordable way to check how much space is left is to use a pre-installed system tool, which is handled by the Security app on Xiaomi smartphones, which has a green icon with a shield, which is integrated into the system at a deep level and provides the most accurate data about the current state of the drive.
Once you start the app, you'll immediately see a pie chart or download bar showing the ratio of occupied space to free space, showing the total capacity of the physical drive and the amount available to the user, and automatically calculating the occupied space by summing up the apps, photos, music and system cache.
⚠️ Note: Do not ignore the red zone of the indicator. If the free space is less than 10% of the total volume, the operating system may begin to forcibly close the background processes, which will lead to the loss of unsaved data in open applications.
For more detailed analysis, click on the Cleanup button or go to the Memory section inside the application, where MIUI will suggest removing junk files. However, it is important to understand that automatic cleaning is not always effective: it often only deletes temporary files that will soon reappear, ignoring large files that occupy real volume.
☑️ Memory status check
Using a built-in scanner is the first step that every user should take when they notice a shortage of space, and it is a basic level of diagnostics that allows them to quickly assess the situation.
Analysis of the storage through system settings
Deeper and more structured analysis is available through the operating system settings menu, a method that is preferred if you want to understand which application or file type takes up the most space, and the path to this menu may vary slightly depending on the firmware version, but the logic remains the same across all the brand devices.
To get to the right section, open Settings and find About phone. From the menu that opens, select Storage. Here are detailed statistics broken down into categories: apps, images, videos, audio, documents, etc. Data visualization helps you instantly identify the memory eater.
- 📱 Appendices: Shows the amount of work occupied by the installed programs and their data.
- 🖼️ Images and Videos: Displays the weight of media files in the gallery and hidden folders.
- 🗑️ Other: a category that often scares users, as it includes system logs, messenger cache and residual files of remote programs.
Clicking on any of the categories, you'll go to a detailed list, for example, in the app section, you can sort them by size and see that Telegram or TikTok can take up tens of gigabytes, and you can immediately go to manage a particular application to clean its cache or data.
💡
The category "Other" is often inflated by social media cache. Regular manual cache cleaning in app settings can free up up to 5-10 GB of space.
This settings section is the main tool for deciding what to delete and what to leave, and here you see the real picture of your Xiaomi resource allocation.
Use of the "Conductor" application for manual search
Standard settings give the big picture, but point-to-point file management is required. Xiaomi smartphones have File Manager preinstalled with a yellow folder on the icon, which allows you to see the file system as it exists physically.
When you run the Explorer, you'll see internal categories and a path to the root folder, and the Internal shared storage folder is of particular interest, and that's where all user data is stored. Navigating the folders allows you to find forgotten downloads, old archives, and duplicate photos that you can't see in the gallery.
For example, the Android/media/com.whatsapp or Tencent/MicroMsg path (for WeChat) can contain gigabytes of video and documents received, and many users do not even suspect that these files are taking up space, since they are hidden from standard viewing in the gallery.
Hidden Android folders
Manual Explorer search is the most efficient way to find specific files to delete or move, giving you complete control over the file structure of the device.
Hidden functions and engineering menu
For advanced users who want to get the most technical information about the state of the drive, there are hidden partitions of the system. In MIUI and HyperOS, they are often accessed through special codes in the Phone application, which allows you to see technical statistics that are not available in the usual interface.
One of the most useful memory diagnostic codes is ##6484##. When you enter it, you'll be taken to the CIT (Customer Interface Test) menu, where you can select the Internal Storage or Storage test to see the technical report on the health of the drive, the number of write cycles and the current response rate.
| Parameter | Description | Norma. |
|---|---|---|
| Total Size | Full physical memory capacity | Depends on the model. |
| Free Size | The available space right now | > 10-15% |
| Used Size | System and user occupied space | Variable |
| Health Status | Technical condition of memory chip | Good |
Using the engineering menu requires caution, changing the settings in this section without understanding their purpose can lead to unstable system operation, but viewing statistics is completely safe and useful for diagnosis.
This method is suitable for those who want to make sure that the hardware of the smartphone is working properly or are looking for the cause of sudden freezes associated with the disk.
Why does memory fill up on its own?
A common complaint from users is, "I cleaned it up, but it's over again after a week," which is normal for today's Android operating systems, and the way apps work involves constantly creating temporary files, cache and logs to speed up content loading.
The main culprits are usually social media and instant messengers. Telegram, Viber, WhatsApp and Instagram automatically store all the photos and videos you've viewed into internal memory. Even if you just flip through the tape, the media files are cached by taking up space. Without manual settings or periodic cleaning, this process is endless.
System updates and error logs are also worth considering: If an application crashes frequently, it can generate huge log files that take up hundreds of megabytes. In addition, some games do not delete old resource packets after an update, leaving them deadweight on the disk.
⚠️ Note: Memory Extension, which uses a portion of the internal storage as RAM, also takes up a fixed amount (usually a fixed amount). 2-5 GB), which the system marks as reserved.
Understanding the nature of these processes helps not to panic at the sight of filling memory, but to systematically adjust automatic cleaning or change the habits of using applications.
Effective methods of vacating space
Once you've figured out where to look for memory and what's taking up it, that's the cleaning phase, and the easiest way is to use the built-in Cleanup feature in the Security app, which is secure and deletes really unnecessary temporary files, but deep cleaning requires more drastic measures.
The first thing to do is clear the cache of heavy applications. Go to Settings → Apps → All apps, select a “gluttonous” app (like YouTube or TikTok) and click Clear the cache. Don’t confuse it with the “Clear Data” button, which will reset the app to factory settings and require re-authorization.
- 🗑️ Removing Duplicates: Use built-in tools or third-party apps to find the same photos and videos.
- ☁️ Cloud services: set up sync with Google Photos or Xiaomi Cloud and enable the “Free Space” feature, which will delete local copies of already uploaded photos.
- 📥 Download folder: regularly check the Download folder where the installation folders accumulate APK-files and documents from browsers.
If even after all the procedures, the space is critically small, transfer some of the data to an external drive (if the model supports memory cards) or to a computer. In extreme cases, a complete reset to factory settings is a radical method, but this requires prior backup of all important information.
💡
Regular preventive cache cleaning once a month is more effective than emergency file deletion when memory is crowded.
Compliance with these simple rules will allow your Xiaomi to work quickly and consistently, avoiding situations where the phone refuses to take calls or take photos due to space shortages.
