Owners of Xiaomi smartphones sooner or later face the problem of lack of free space. the MIUI operating system or the new HyperOS requires resources for stable operation, and the accumulated data can critically slow down the device. When the notification of memory overflow appears on the screen, the gadget begins to work slower, and applications stop updating.
Effective cleaning allows you to return performance and extend the life of the drive. In this article, we will discuss proven methods for removing garbage, hidden copies and temporary files that take up gigabytes of space.
Analysis of vault occupancy
Before we start taking drastic measures, we need to know exactly what's taking up space, and built-in memory analysis allows us to visualize the distribution of data into categories, which helps us understand whether photos, installed apps or messenger cache are to blame for the lack of space.
To start your diagnosis, go to Settings → About Phone → Storage. The system will show a pie chart, where different colors are highlighted in the sections “Apps”, “Images”, “Video” and “System files.” Notice the “Other” section, which often contains hidden debris.
⚠️ Note: Do not delete files from system folders that you do not know the purpose of, this can lead to unstable Android operation.
Sometimes the user thinks that the space is occupied by photos, but in fact, the bulk of the consumption of cache streaming services, the targeted impact on the problem areas is more effective than blind cleaning all the time.
Use of the built-in Security application
The easiest and safest way to remove unnecessary files is to use the regular Cleanup tool. The MIUI and HyperOS shells pre-installed the Security app, which has access to system files and can delete them without risking damage to the OS.
Launch the app and select Clean up. The scanner will analyze the device and prompt you to delete temporary files, remnants of deleted apps and advertising debris. After you complete the scan, click Clean up to make room.
☑️ Checking before cleaning
Deep Cleaning allows you to find large files, duplicate photos and unused apps, a powerful tool that is often ignored, preferring third-party software. However, Xiaomi’s built-in algorithm works correctly and does not require additional permissions.
Using this tool regularly helps keep things in order, and you can set up automatic cleaning to allow the phone to make room when it reaches a certain occupancy threshold.
Manual cleaning through the conductor
For more advanced users, manual sorting through standard Explorer is available, and this method allows you to see the real file structure and delete exactly what you want, not what the algorithm has decided. Open the Explorer app and go to the root folder of the internal drive.
First of all, look at the Download folder, which is where all the files from the Internet, documents and application installers are stored, and often hundreds of megabytes of forgotten APK installers and presentations are accumulated.
- 🗑️ Remove old application installation files that are no longer needed.
- 📂 Check the folders of WhatsApp and Telegram messengers, they often inflate to giant sizes.
- 🎵 Find and remove forgotten music tracks or podcasts.
It's also worth checking the DCIM folder, where the camera's shots are stored, sometimes there are bad shots or long videos that you can transfer to your computer, and manually structuring files takes longer, but gives you better results.
Hidden folders in the Explorer
Don't forget the folder. MIUI, which may contain a folder debug_log. Some apps record error reports that can take several gigabytes over time.
Cleaning the cache of applications and messengers
Social networks and instant messengers are the main consumers of memory on today’s smartphone. apps like Telegram, VK or Instagram store every photo and video you see in cache so that they can be uploaded faster when you reopen it.
To delete this data, go to Settings → Apps → All apps. Select the app you want (like Telegram) and click on Storage. There you will see the Clear Cache button. This action is secure and will not delete your correspondence.
⚠️ Warning: Do not confuse the Clear Cache button with the Clear Everything button (or Delete Data) and the second button will completely reset the app by removing logins, passwords and correspondence history.
The messengers themselves also have built-in memory management tools. For example, Telegram can set up autodelete cache. Go to Settings → Data and memory → Memory use and set a limit, for example, 1 GB. Old files will be deleted automatically.
Regularly checking the cache of video services like YouTube or Netflix is also important: If you’ve watched a lot of videos offline or just actively used the service, the cache can grow to unprecedented sizes.
Removal of duplicates and similar photos
The smartphone gallery will eventually become full of dozens of identical shots taken in serial mode, or screenshots that are no longer relevant.
The newer versions of MIUI's Gallery app, which is built-in, has a feature to find similar photos, and you can use Albums → Screenshots for quick revision, and removing unnecessary copies is a quick way to get back a few gigabytes.
To find duplicate files (not only photos, but also documents), you can use specialized utilities, but often enough to look carefully at folders in Explorer.
- 📸 Sort the photo by size and remove blurred or unsuccessful frames.
- 📄 Find duplicate documents in the Documents folder».
- 🎥 Check the video files, they take up the most space in the gallery.
Once deleted, the files are put in a basket where they're stored for another 30 days, so to make room, remember to clean the Recycle Bin in the Gallery and Explorer app, and then the disk space is really free.
Comparison of Memory Cleaning Methods
There are many ways to free up space, but their effectiveness and safety vary, and here is a table to help you choose the best method for your situation.
| Method | Security | Efficiency | Difficulty |
|---|---|---|---|
| Security annex | Tall. | Medium | Low. |
| Manual cleaning by the Conductor | Medium | Tall. | Medium |
| Reset to factory settings | Low (Data Loss Risk) | Maximum | Tall. |
| Cleaning up the app cache | Tall. | Medium | Low. |
As the table shows, regular funds provide the best balance between safety and outcome, and radical methods such as total reset should only be used in extreme cases where other methods have failed.
💡
Before any large-scale deletion of files, back up your important data in the Mi Cloud or on your computer.
Combining the methods is the best thing. First, use automatic cleaning, then manually disassemble large files, and then finally clean the cache of heavy applications, which ensures order in the system.
Transferring data to external storage and to the cloud
If internal memory is crowded and deletion is pathetic, data can be moved. Xiaomi smartphones often support microSD cards or connectivity USB-flash-drive OTG.
To transfer files in Explorer, select the photos or videos you want, click Move, and select the memory card, which will free up the internal space, leaving the files available for viewing. SD-map.
The alternative is Mi Cloud cloud storage or third-party services like Google Photos. By setting up sync with Free Space, you can delete the originals from your phone by leaving them in the cloud. This is a modern approach to data storage.
💡
Using cloud storage is the best way to keep your phone’s memory free without losing access to your photo archive.
You don't want to store movies and TV shows on your phone if you're not watching them right now. You can delete the file after you've watched it, making room for new content. Digital hygiene should become a habit.
