Xiaomi’s current smartphones are packed with a huge amount of storage, but even 256 or 512 gigabytes can get busy over time. Users are often notified that space is running out, which leads to slowdowns, inability to install updates or record new photos. Understanding exactly how space is distributed is key to keeping the device performing well.
MIUI and the new HyperOS have powerful tools to monitor and manage files. However, standard notifications don’t always give a complete picture of what is eating gigabytes. In this article, we’ll look at how to make a deep diagnostic of storage, distinguish system files from user files, and safely clean up unnecessary digital junk without losing important data.
Monitoring the state of the drive helps to extend the life of the smartphone. When free space is critically low, the speed of writing data decreases, and the wear of memory cells increases, regular checking avoids sudden freezes and problems with the operation of applications.
Storage analysis tools in MIUI and HyperOS
The first thing that Xiaomi owners need to do to assess the situation is to use the built-in analyzer, which provides enough detail about which categories of files occupy the most space, and you don't need to install third-party software to access this data, just go to the settings.
Search the Settings menu, then go to About Phone and select Memory. Here you will see a color diagram showing apps, images, video, audio and system files in different colors. Clicking on a specific sector, you can see details, such as which apps occupy the most space.
The alternative is to use the system application Security, which has a built-in Cleanup tool that scans the device for temporary files, remnants of deleted programs and cache, a method that is less informative for in-depth analysis, but convenient for quick assessment of the general condition.
- 📊 Visualization: Color diagram allows you to instantly estimate the proportions of occupied space.
- 🗑️ Smart cleaning: The system itself offers to remove duplicates and screenshots.
- 📱 Application analysis: You can see which app weighs as much as the data.
- ⚙️ System Files: Separately highlighted the partition occupied by the operating system.
It is important to understand the difference between the amount of physical memory that the system displays and the actual amount of physical memory. Part of the space is always reserved for system partitioning and formatting, so on a device with a declared 128 GB of user data, about 110-115 GB can be available.
Detailed Diagnostics through Conductor and Hidden Functions
If standard analysis isn't enough, File Manager comes to the rescue, and unlike settings, it shows the real folder structure on the drive, which is especially useful when you need to find specific heavy files left by messengers or downloaded from the Internet.
Open Explorer and click on the folder icon at the top menu, and you can sort files by type, but the power comes from the location analysis function, and some versions of the shell, if you press the storage icon long enough, open an extended menu where you can see hidden folders and the system cache.
⚠️ Note: When working with files through Explorer, be extremely careful with Android, data, and obb folders. Deleting the contents of these directories can lead to resetting of game progress or incorrect operation of installed programs.
For more advanced users, it is possible to view the location via ADB (Android Debug Bridge) by connecting the phone to a computer. the adb shell dumpsys diskstats command allows you to get technical statistics on partition usage, but this method requires a PC and a configured debugger.
What is a Data Section and Can I Touch It?
Using third-party file managers like Total Commander or FX File Explorer also gives more flexible tools to sort files by size.This helps find forgotten videos or archives that can take up gigabytes of space.
Application location analysis: cache and data
Often, the main memory eater is not photos, but social networks and instant messengers. Telegram, WhatsApp, Viber and TikTok tend to accumulate huge amounts of cached data, over time, the cache can reach 10-20 gigabytes, which significantly affects the state of memory.
To check the location of a particular application, go to Settings → Applications → All applications. Select the desired program and click Memory. Here you will see the division by the size of the application itself, the amount of user data and the size of the cache. Cache can be safely cleared with the Clear Cache button.
☑️ Checking heavy applications
Special attention should be paid to the "Data Cleanup" function. Unlike cache, it deletes logins, passwords, correspondence and settings within the application, use this option only if you want to completely reset the state of the program or delete it if standard deletion is not available.
- 🧹 Cash: Temporary files that can be deleted without fear.
- 💾 Data: Personal Information that requires caution in deleting.
- 📦 Size APK: The weight of the installation file is usually small.
- 🔄 Background Processes: Can create temporary files in the background.
Some applications, like navigators or streaming services, allow you to download content for offline use. Forgotten downloaded maps or song lists can take up a significant amount of space. Check the settings of such programs and remove unnecessary offline content.
Working with multimedia and gallery
Photos and videos are what users most often save to a device. Xiaomi's modern cameras take high-resolution pictures, and video can be written in 4K, which very quickly consumes free space. One minute of video in 4K can take up to 400-500 MB.
The Gallery app has a built-in cleaning tool. Click on three dots in the corner and select Cleanup. The system will suggest removing blurred photos, similar pictures and screenshots. It's also worth checking the Recently Deleted folder, as the files are stored there for 30 days and continue to take up space.
⚠️ Warning: Before mass cleaning of the gallery, be sure to back up important photos and videos on the cloud service (Google Photos, Mi Cloud) or on your computer.
Check the messenger folders in the gallery. Often, a WhatsApp Images or Telegram album accumulates thousands of advertising pictures and unnecessary stickers, you better set up automatic download of media in messengers only via Wi-Fi and turn off auto-save in the gallery.
💡
Use cloud-based archive storage services. Set up automatic uploads to Google Photos with a "Free Space" feature that will delete copies from your phone, leaving them in the cloud.
Table: Comparison of memory cleaning methods
To make it easier to choose a way to optimize storage, we will look at the basic methods and their effectiveness in a comparative table, which will help you understand which tool to use in a particular situation.
| Method | Security | Efficiency | Difficulty |
|---|---|---|---|
| State Cleaning (Safety) | Tall. | Medium | Low. |
| Manual removal in the Conductor | Medium | Tall. | Medium |
| Cleaning up the app cache | Tall. | Medium | Low. |
| Reset to factory settings | Low (Data Loss Risk) | Maximum | Tall. |
As you can see from the table, regular funds are the safest, but they don't always get the best results. Manual file processing is more efficient, but it requires knowledge. Reset is the last resort that puts the phone back into a store-like state.
Advanced methods and work with SD-card
If internal memory is constantly lacking, consider expanding storage. Many Xiaomi models support microSD cards. Bringing photos, videos and music to an external card will free up a fast internal drive for the system and applications.
In modern versions of Android and MIUI the ability to transfer the applications themselves to SD-The card is limited or missing to ensure stability of work, but you can change the way you save photos and videos in the camera settings so that they are immediately written to the map.
💡
Use of the SD-Multimedia cards are the best way to free up internal memory without deleting important data and applications.
There is also a method of formatting a memory card as internal storage (Adoptable Storage), but it is not available on all models and requires flashing or using special ADB commands. This can slow down the phone, since the memory cards are usually slower than the built-in module.

Regular monitoring of memory status on Xiaomi is a habit that will save you from many problems. Use a combination of standard tools for quick cleaning and manual analysis for deep optimization. Remember that having at least 10-15% of the free space of the total volume is necessary for the operating system and virtual memory mechanisms to work correctly.
