How to see memory on Xiaomi phone

Modern Xiaomi, Redmi and POCO smartphones offer users a huge number of options, but even the most powerful processor will not be able to work quickly if internal storage is crowded. When space runs out, the device starts to run slower, applications fly out, and the system can stop saving new photos or updates. Many users face a mysterious message about a lack of space, although it seems nothing extra downloaded, in which case you need to know exactly how to look at the memory on the Xiaomi phone to understand what exactly takes up precious gigabytes.

In this article, we’ll look at all the available ways to diagnose storage, from standard MIUI and HyperOS tools to advanced methods of analysis through an engineering menu. You’ll learn to distinguish app cache from system files and understand why the amount of “busy” can differ from the actual weight of your photos and videos. Proper analysis is the first step to speeding up your gadget.

We will look not only at visual occupancy assessment, but also at the technical details of RAM and ROM resource allocation. Understanding these processes will allow you to manage files competently without removing anything superfluous, and maintain the performance of your smartphone at a high level for many years.

Checking through the standard Security application

The easiest and most affordable way to know how much space is left is built into the default firmware. Xiaomi preinstalles Security, which serves as the main resource management center of the device, and that's where diagnostics often begin, because it's where the information is presented in the most understandable way for the average user.

To access the data, open the app and find the Cleanup option. The system will automatically scan the device and give you a summary of how many megabytes or gigabytes can be freed up right now by removing garbage. However, for a more detailed analysis, you need to click on a pie chart or the Detail button, usually located in the center or at the bottom of the screen, and here you will see a breakdown by category: images, videos, applications and documents.

⚠️ Warning: Do not use the "Accelerate" function too often. Constant forced cleaning of RAM can cause the system to reopen background applications, which increases battery consumption.

It is important to understand the difference between clearing a cache and deleting data. When you click the clear button on this menu, the system deletes temporary files that do not affect the operation of programs. However, if you decide to clear the data of a particular application through settings, you may lose logins or progress in games. Always check what is marked with the tick before final confirmation of the action.

Detailed analysis in storage settings

For a deeper dive into the file structure, you should refer to the Android system settings. This section provides more accurate information about how disk space is distributed, and allows you to manage file categories directly, without third-party utilities.

Go to the Settings menu, then select About Phone and click on Storage (or Memory). In newer versions of the HyperOS shell, this item can be immediately in the main settings menu. You will see a list of all categories occupying space, from system files to downloaded documents from the Internet.

  • 📱 Apps: Shows the weight of installed programs along with their data and cache.
  • 🖼️ Images and videos: media files from the gallery, screenshots and downloads of messengers.
  • 📂 System files: data required for the operation of the OS that cannot be deleted without loss of functionality.
  • 🗑️ Other: often the most mysterious category, including browser cache, remnants of remote programs and archives.

You should pay special attention to the App item. Often, instant messengers like Telegram or WhatsApp take up tens of gigabytes because of the accumulated media files. In this section, you can select a specific application and click Clear cache to make room without deleting correspondence. If you choose Clear everything or Erase data, the application will return to state immediately after installation.

☑️ Checking the vault

Done: 0 / 1

Automatic analyzers don't always see everything. Sometimes large files hide in deep directories or have custom extensions. For these cases, the indispensable File Manager is a tool that allows you to manually examine the folder structure and find the heavyweights that the system missed.

Launch Explorer and go to the Folder tab, which shows the entire file system. Look for folders called DCIM (camera), Download (downloads) and MIUI (system data). Inside the MIUI → Gallery → cloud folder, thumbnails and deleted photos often accumulate, which take up space but are not visible in the gallery.

So, for easy search of large files, use the sorting function. In Explorer, you can sort files by size by selecting the option "Size -> On descending. This instantly lifts up the videos and archives that weigh the most. Often users forget about downloaded movies or backups that lie dead for months.

Hidden Android folders
The Android/data folder contains the application data. In the past, you could go freely, but in newer versions of Android, access is limited. Viewing may require a third-party file manager with extended rights.> Table: Memory Type Distribution in Xiaomi To get a grip on the terms, let's organize the information. Understanding the difference between memory types will help avoid cleaning errors. Below is a table explaining the basic concepts you will encounter in the analysis. Type of memory Designation Designation Can I clean the operational RAM Temporary storage of running applications Yes (automatically) Internal ROM / UFS Storage of photos, OS, applications, music Partially (user files) Cache Temporary files for fast download Yes (safe) System System System System Firmware and kernel No (breakdown risk) As can be seen from the table, the main threat of overflow is internal memory (ROM). RAM is cleaned by itself when rebooting or lacking resources, so all efforts to vacate space should be focused on analyzing the file storage, not constantly cleaning up the file storage. RAM. It's worth noting that the amount of memory available is always less than the specified data, part of the space is reserved for the system partition and service needs. If the box says 128 GB, the user has access to about 110-115 GB. This is a normal situation, not a marriage or a cheating of the manufacturer (RAM) Often, when people ask how to view memory, they're asking the amount of RAM that multitasking depends on. RAM So you can use the developer menu or the sidebar right now. MIUI Just swipe open the menu of running applications and look at the top of the screen, where the free volume is displayed, for example, 4.5 GB / 8 GB. For more detailed statistics, activate the developer menu. MIUI or OS In the section About phone. After activation in the settings will appear a new item Additional -> For developers, you can run the Display Memory mode, and there's always a use counter in the corner of the screen. RAM real-time. If you see RAM being 90% full even without heavy gaming, there may be too many services running in the background, and in such cases, the Extension Memory feature helps, which takes a piece of internal storage and uses it as virtual RAM. This option is in the Additional section -> Expanding memory and requires restarting the device. ⚠️ Note: Memory expansion function is slower than physical memory expansion RAM. Don't expect performance marvels in games, it's more useful for keeping more apps in the background. Hidden sections and engineering menus For advanced users, there is a way to arrange complete technical information through an engineering menu. This is a hidden part of the system that's designed to test the hardware, and you can see the exact wear of the battery, the status of the memory cells, and other technical parameters that are hidden from the normal interface. To get there, open the Phone app and enter the code ##6484##. CIT. You can choose Storage or Internal Storage, and the system will test the total volume, the space used, and, importantly, the health status of the drive, and if the memory has critical errors, the system can report this, which will signal backups. Code for logging into the engineering menu: ##6484## Also in this menu you can check if the device is remade (refabricated), where the memory was soldered software. This is useful when buying a used phone to make sure the honesty of the seller. 💡Engineering menus are a powerful diagnostic tool, but beware: changing settings in other sections CIT This can cause unstable phone operation. Frequently Asked Questions (FAQ) Why does Xiaomi memory fill up on its own? This is due to messengers that automatically upload photos and videos to chat rooms, and the accumulation of browser and social media cache. Regularly cleaning the cache solves the problem.
