Xiaomi’s modern smartphones have a powerful hardware, but over time, even the top models start to work slower. The main reason for the performance decline is the overflow of internal memory with temporary files, remnants of remote applications and accumulated cache. Users often notice that free space mysteriously disappears, and the system begins to slow down when switching between tasks.
Cleaning up a device is not just about removing photos or videos, but about a comprehensive maintenance process for Android and the MIUI or HyperOS shell. A competent approach to freeing up space allows you to extend the life of the drive and restore the responsiveness of the interface. In this article, we will discuss safe and effective methods for removing digital debris using built-in tools and proven third-party utilities.
Analysis of vault occupancy
Before taking action to remove data, you need to conduct a thorough review of what exactly takes up space. Xiaomi owners often do not even suspect that the lion’s share of memory is occupied by the messenger cache or forgotten downloads from the browser. The first step is to visit the device’s settings to visually assess the situation.
In modern firmware versions, the memory information is visualized. You need to go to the Settings menu. → Memory (or Settings) → The phone. → Storage. Here, the system will show a pie chart of the data distribution. Pay attention to the categories "Applications", "Images" and "System files».
Visual analysis helps quickly identify the space eaters, and it often turns out that a single social network takes up tens of gigabytes because of the auto-save of all the photos and videos you see, and understanding the structure of storage is half the success of the free gigabytes struggle.
- 📊 Check the overall occupancy of the internal drive.
- 📂 Identify the top-3 Applications occupying the most space.
- 💾 Estimate the size of the folder “Downloads” and “Documents».
It's worth noting that a standard analyzer might not show hidden folders of some programs, but for deeper immersion, you can use file managers with directory tree analysis, which allows you to see the real size of directories that are usually hidden from the user's eyes.
Use of the built-in "Security" application
Xiaomi is preinstalling a powerful system tool called Security into its smartphones, not just an antivirus, but a whole system maintenance combine that includes an efficient cleaner, and it is recommended to start cleaning regularly to prevent critical memory filling.
To get started, open the Security app and select Cleanup. The system will automatically scan the device for temporary files, advertising debris and residual files from remote applications, taking 10 to 30 seconds depending on the amount of information accumulated.
⚠️ Note: When using Deep Clean, carefully monitor which files are tagged for deletion. Sometimes the system may mistakenly classify important documents or offline maps of the navigator as garbage.
Once you scan, you'll see a list of categories: app cache, large files, unused apps. When you click the cleanup button, you'll make room instantly. However, for messengers like WhatsApp or Telegram, it's better to use specialized sections inside the Security app itself to selectively delete only heavy video files, saving correspondence.
- 🚀 Run a standard cleanup to remove temporary files.
- 🗑️ Use Deep Cleanup to find duplicates and large files.
- 📱 Remove unused applications through the same interface.
☑️ Daily rapid cleaning
It's important to understand that app cache is data that speeds up the process, like thumbnails in a gallery or stored data in a browser. Periodic cache cleaning is useful, but if you do this too often, applications can start to run a little slower on the first run, reloading the necessary resources.
Manual cleaning through the conductor
Automatic tools don't always find specific debris left behind by specific programs. Manual cleaning through the built-in File Manager gives you complete control of the file system. This method requires caution, since you work with files directly.
First of all, check the Download folder, which saves all files from the Internet, documents, APK installation packages and email attachments by default, and users often forget about files downloaded a year ago that are hanging in memory deadweight.
You can also look at social folders, and you can find com.whatsapp, com.tencent.mm (WeChat) directories in the root directory or in the Android/media folder, and many others, and they often store the Video and Image folders, where all the media you've viewed is stored.
| folder | Description of the contents | Recommendation |
|---|---|---|
| Download | Files from the browser and bootloader | You can remove it boldly. |
| DCIM/.thumbnails | Photo miniatures | Clean up when there is a shortage of space |
| MIUI/debug_log | Logs of system debugging | Safe to remove |
| Tencent/MicroMsg | WeChat cash | Remove only the media |
Deleting the.thumbnails folder in the DCIM directory can temporarily speed up the gallery if it slows down when you scroll through thousands of photos, but the system will create it again.
When manually cleaning, always check the file extension. Files with the.log,.tmp and.bak extensions are often technical garbage. However, files with the.db extension can be databases of important applications, and deleting them will lead to resetting program settings.
Cleaning cache and data of specific applications
Some applications, especially social networks and browsers, are growing to giant sizes. Standard system cleaning may not reach their deep layers. For these cases, there is a mechanism for managing applications in Android settings.
Go to Settings → Apps → All apps. Select a “heavy” app like YouTube or Instagram. In the menu that opens, look for “Memory” or “Storage.” Here you will see two buttons: “Clear Cache” and “Clean Everything” (or “Reset”).
Clearing the cache is safe and only deletes temporary files. The Clear Data button completely resets the app to the state immediately after installation: you will crash out of your account, your saved passwords and settings will disappear within the program. Use this method only if the application is not working correctly or takes up a critical amount of space, and its data does not matter to you.
- 📲 Find the memory consumption leader app in the list.
- ⚙️ Go to his storage.
- 🧹 Click “Clear Cache” to free up space without losing data.
What to do if the cache clean button is inactive?
Pay special attention to offline maps (Google Maps, Yandex.Maps, 2GIS) that can take several gigabytes. These apps have a separate section for managing downloaded maps, where you can delete unnecessary regions without removing the application itself.
Removal of duplicates and large files
Over the years of use, the smartphone gallery has accumulated hundreds of identical shots taken in serial mode, or screenshots that are no longer relevant. Duplicate photos is the easiest way to quickly make room without losing quality content.
You can use the built-in MIUI gallery features to find these files. The Albums section often has a Screenshots or Video category where you can sort files by size. The Security app also has a Big Files tool that ranks all objects by volume.
Deleting video files has the greatest effect. One minute of writing in 4K can take up to 400 MB of memory. Revisit your video archives and delete bad duplicates. For photos, use cloud services like Google Photos or Yandex.Disk, which allow you to compress the originals or remove them from the device after backup.
⚠️ Attention: Before mass deletion of photos, make sure they are synced to the cloud.Deletion of a file in the Xiaomi gallery often leads to its removal from the cloud storage, if sync is enabled.
Remember the Recycle Bin folder in the gallery. Deleted files often stay there for 30 days, continuing to take up space. To free up memory immediately, you need to go to the Deleted album and clean it completely.
Specialized cleaning applications
If there is not enough built-in tools, third-party solutions from Google Play come to the rescue, but be selective: many “cliners” are themselves a source of advertising and garbage, and time-tested utilities with good reputations are the best choices.
Files by Google is one of the market leaders, and it's not only looking for garbage, it's also able to find similar images, old screenshots and rarely used apps, and it's very delicate and rarely removes anything that's superfluous — SD Maid (version) SE), It is famous for its deep analysis of the “bodies” of remote applications.
Using third-party software is especially useful for cleaning up garbage after uninstall (delete) programs. Often application developers leave their folders with logs and settings even after the user has deleted the program. Specialized scanners find these “orphaned” files.
💡
Don’t install more than one cleaning app. They can conflict with each other, running cleaning processes at the same time, which will only slow down the smartphone.
Remember that cleaners that promise to speed up your phone 5 times or cool your processor are often marketing ploys. Real acceleration only frees up free disk space (at least 10-15% of the total) and shuts down heavy background processes.
Prevention and configuration of messengers
The main source of garbage on modern smartphones is messengers. WhatsApp, Telegram, Viber by default store all received media files in the memory of the device, changing the settings inside these applications can save gigabytes of space monthly.
On WhatsApp, go to Settings → Data and Storage. Turn off gallery save for all chat types or select only favorite contacts. You can also set up autodelete messages. On Telegram, the situation is even more interesting: in Settings → Data and memory → Memory Use, you can set a cache limit. Once the cache reaches the limit (for example, 1 GB), old files will be automatically deleted.
This is the most effective prevention method. Once you set up a cache autocleaner once, you'll never again have a problem with overflowing memory from correspondence. The media files you really need can always be saved manually to Favorites or to your device.
- ⚙️ Turn off auto-save photos in the gallery for all chats.
- 📉 Set a cache limit in Telegram for 500 MB - 1 GB.
- 🗑️ Set up autodelete messages after 1 year.
💡
Setting up auto-delete cache in Telegram and WhatsApp solves up to 80% of memory problems on Xiaomi smartphones in the long run.
Regularly checking the settings of messengers should become a habit. Application updates sometimes reset user preferences, returning autosave media files, so it is worth rechecking these parameters every six months.
