Xiaomi and Redmi smartphone owners often face a situation where available space on the device is rapidly shrinking. Internal memory, seemingly just freed up, is refilled in a matter of days. This causes irritation, slows down the interface, prevents new applications from being installed or high-resolution images. The MIUI system (HyperOS) is designed so that many processes leave behind traces that the user can not always immediately detect.
The main cause of the problem lies not in one particular file, but in a combination of factors: the work of messengers, system cache, duplicate photos and the features of the MIUI shell. Unlike “pure” Android, there are many pre-installed services that actively generate data. Understanding where these gigabytes hide is the key to successfully optimizing the device without losing important data.
In this article, we’ll take a closer look at the storage structure, learn how to find hidden folders, and use built-in tools to analyze disk space. Xiaomi provides powerful tools for managing files, but they’re often hidden in the depths of the menu or require the right approach to setup.
Analysis of the storage occupancy of built-in tools
Before you delete anything at random, you need to do a good diagnostic. Standard conductor and system settings allow you to see the big picture, but for deep analysis you need to use a specialized section. Go to Settings → Memory to see the data distribution diagram. Here the system categorizes files into applications, images, video, audio and so on.
But standard categorization often hides the real problem, such as the “Other” section that can take up tens of gigabytes, such as system debris, update cache, remote application files, or data that the system could not correctly identify. For more accurate analysis, it is recommended to use the built-in “Security” application from Xiaomi, which has a more advanced scanner that can find large files and duplicates.
⚠️ Note: Do not rush to clean the "Other" section forcibly through third-party software-cliners. Aggressive removal of system files can lead to unstable HyperOS or MIUI, and also the loss of application settings.
Use the Cleanup feature in the Security app regularly but wisely. The system will prompt you to delete temporary files, but always check the list before confirming. Often there are important cached data that will have to be re-uploaded, consuming traffic.
Messengers as the main consumers of space
The first place in memory consumption on most smartphones is occupied by messengers: WhatsApp, Telegram, Viber. These applications by default store all received media files in internal memory. If you are in dozens of groups and channels where you share photos and videos every day, your phone becomes a repository of other people's content.
Telegram, for example, has a default feature called "Save to Gallery" which means that every video or photo you see from the channel is duplicated into the system gallery. To fix this, go to Settings → Data and Memory. You need to turn off auto-save for all types of chats or limit it to personal dialogues. It's also useful to set a cache size limit.
- 📱 WhatsApp: Go to Settings → Data and storage → Storage management.You can safely delete files larger than 5MB or clear specific chats here.
- ✈️ Telegram: Use the built-in Memory Use feature to clean up the cache. Set a cache limit, such as 1GB, so that the app itself deletes old data.
- 📞 Viber: In the settings, find Memory and turn off Gallery Saving. Regularly delete call history and media from group chats.
💡
In Telegram, you can turn on “Fast Media” in the settings, which will allow you to view photos and videos without fully downloading and saving them to the disk, saving space.
Remember that even after cleaning the cache inside the application, files can remain in the folders of the system. To completely clean you will have to use the file manager and check the folders Android/media or MIUI/gallery/cloud, where often the tails from deleted messages remain.
System folders and hidden MIUI garbage
The MIUI shell and the new HyperOS create many service folders that grow over time. One of the most famous problems is the MIUI/Gallery/cloud/cache folder, which stores sketches of deleted photos. Even if you cleaned the shopping cart in the gallery, these thumbnails can take up gigabytes of space.
Another source of “heavy” files is a folder Android/data. It stores game and application caches, and if you delete a game but it's still in the folder, it won't vacate, and it's worth checking the Download folder. Browsers and social networks often save installation files there. APK, PDF-Documents and pictures that users forget after five minutes.
Hidden folders at the root
To access hidden files, turn on the hidden elements in Explorer. Click three dots in the corner and select the appropriate item. Be careful not to delete folders with system names such as MIUI, Android, System. Only delete their contents inside the application-specific subfolders.
⚠️ Note: When manually cleaning folders Android/data and Android/obb Make sure you don’t delete the files of the games you plan to play, which will result in the need to re-download resources.
Photo Duplicates and HEIC format
Modern Xiaomi cameras take high-resolution shots, and the dual shoot or portrait modes can create additional copies of images, and when synchronized with Google Photos or Mi Cloud, duplicates can occur if the settings have been reset or changed.
Special attention should be paid to the HEIC (High Efficiency Image Coding) format. If you have the High Efficiency option enabled in the camera settings, the photos will take up less space, but when transferred to other devices or to some applications can be converted to JPEG, creating twins. Check the camera and gallery settings for duplicates.
The built-in cleaning tool often suggests finding similar images. The algorithm compares images by visual similarity and suggests leaving the best option. It's a great way to make room without losing memories. It's also worth checking the Screenshots folder, which often accumulates images of interfaces that are no longer needed.
☑️ Checking the gallery for duplicates
Table: Location of the main devouring folders
For easy navigation through the file system, we will make a table of the main directories that require regular checks, the path to them is standard for most Android and MIUI devices.
| folder | The path is the guide | What's stored | Can I remove it? |
|---|---|---|---|
| WhatsApp Media | Android/media/com.whatsapp | Photos, videos, voice from WhatsApp | Yeah (selectively) |
| Telegram Cache | Android/data/org.telegram.messenger | Telegram channels and chats cache | Yes (via app settings) |
| System Cache | MIUI/gallery/cloud/cache | Miniatures of the cloud gallery | Yes. |
| Downloads | Download | Files from the browser and messengers | Yeah (after check-in) |
| App Logs | MIUI/debug_log | Logs of system debugging | Yes. |
Use this chart as a map to find hidden memory reserves. Regular monitoring of these directories will help keep your phone clean. Remember that the Android/data path in newer versions of Android (11 and above) can be hidden from standard viewing, requiring a dedicated explorer or a PC connection.
💡
Regular manual check of folders Download and MIUI/gallery/cloud/cache allows you to free up to 10-15 GB of space on a crowded smartphone.
Advanced methods: ADB and large file analysis
If standard methods didn’t work, and the question of “where did the space on the Xiaomi phone” still matter, you’ll have to move to “heavy artillery.” Using a computer and USB debugging (ADB) allows you to see the real picture of disk usage, including system partitions hidden from the user.
To do this, you need to turn on developer mode. Tap 7 times on the build number in Settings → About your phone. Then activate USB Debugging. Once you connect your phone to your PC, you can use commands to analyze. However, there is a simpler way to install a disk space analyzer application, such as DiskUsage or Storage Analyzer, which visualize files as squares.
adb shell dumpsys diskstatsThis command will show you the data on disk usage, but it's hard for a beginner to read. You'll better use visual analyzers. They'll show you which file is taking up space. Often it turns out to be a forgotten 4K movie, a navigator archive, or a bug application log file that has grown to an incredible size.
⚠️ Note: Use third-party analyzers with extreme caution, deleting system files through such programs can brick your device).
Prevention and Cloud Solutions
To prevent the problem from returning, you need to establish a storage system. The best friend of the owner of Xiaomi with a small amount of memory is cloud services. Mi Cloud, Google Photos, Yandex.Disk allow you to store photos and videos online, leaving only compressed copies on the device or even deleting the originals after downloading.
Turn on the “Free Space” feature in Google Photos, which will automatically delete from the device images that are already stored in the cloud, and reconsider the habit of storing music and movies locally. Streaming services allow you to listen to music online, cache only tracks from current playlists, which takes up minimal space.
Regularly, at least once a month, audit installed applications. Remove those that have not been used for more than three months. Often, these programs tend to accumulate background debris even in sleep mode. Clean file system is the key to fast operation of your smartphone throughout its life.
