Modern Xiaomi and Redmi smartphones have huge capabilities, but even 256 or 512 gigabytes of internal storage can fill up unnoticed by the owner. Android with a MIUI shell or HyperOS actively accumulates temporary files, app cache and error logs, which ultimately leads to a critical slowdown of the device. When internal memory is full, you notice lags in the interface, long runs of programs and the inability to take a new picture or install an update.
Many users make the mistake of only deleting photos or unwanted contacts, believing that this will solve the problem. In fact, system debris and hidden folders of messengers take up much more space than it seems at first glance. In this article, we will discuss proven deep cleaning methods that will help return the gadget to its previous speed and free up gigabytes of useful space without losing important data.
To begin with, we need to assess the current state of storage to understand what we are struggling with. On Xiaomi devices, the “Others” folder often grows to tens of gigabytes, hiding the remnants of remote applications and temporary system files. A competent approach to cleaning requires not chaotic deletion, but understanding the structure of files and using built-in optimization tools.
Storage occupancy analysis and search for hidden files
Before you take decisive action, you need to determine exactly what is eating up space. Xiaomi smartphone owners have a built-in tool for this, but it does not always show the full picture. The standard memory analyzer allows you to see the distribution of space between applications, images, videos and system files, but some directories can remain hidden.
Use the built-in analysis function by going to Settings → Memory. This is where the system will offer to clean up the garbage, but often this is not enough. You can do a deeper analysis through the Explorer app by selecting file sizes. Often it turns out that the largest volume is not occupied by photos, but by the cache of streaming services or offline maps of the navigator.
Note the Android/data folder, which stores cached game and heavy-duty apps data. Deleting the contents of this directory can free up a significant amount of volume, but will require re-loading resources the next time programs run, a trade-off between speed and traffic that is worth considering.
Using the built-in “Security” app for quick cleaning
The easiest and safest way to start the fight for space is to use a regular shell developer utility, Security is pre-installed on all Redmi and Xiaomi smartphones and contains a Cleanup module, which automatically scans the system for temporary files, advertising debris and residual data.
Launch the app and press the Clean button, and the system will prompt you to delete files that do not affect the stability of the OS. However, to get the maximum effect, you need to go to the advanced cleaning settings, and you can select deep analysis. APK-files, large files and duplicates that often remain after updates or data transfers.
☑️ Checklist for quick cleaning
It is important to understand the difference between cache and application data. Cache cleaning is secure and only removes temporary files, speeding up work. Deleting data will reset the application to the state of the original installation, which will require re-authorization. Be careful when choosing options in the application management menu inside the utility.
Manual cleaning of messengers: Telegram, WhatsApp and Viber
Messengers are the main memory eaters on modern Android smartphones. Telegram, for example, by default caches all the media files viewed, turning the application folder into a storage of tens of gigabytes. Without manual configuration, this data will be stored forever, even if you have already deleted correspondence.
To clean up Telegram, go to Settings → Data and Memory → Memory Use. You can see the space you occupy and click “Clear Cache.” It is recommended that you also enable the autodelete cache function by setting a shelf life for, for example, 3 days or 1 week, which will prevent the accumulation of garbage in the future.
⚠️ Note: Clearing WhatsApp or Viber data through your Android settings will completely delete your correspondence history if you don't have a backup.Use the built-in cleaning features inside the apps themselves!
On WhatsApp, the situation is similar: go to Settings → Data and Storage → Storage Management. The system will show files larger than 5 MB and chat rooms that take up the most space. You can selectively delete heavy videos or documents, saving text correspondence.
Where to look for hidden messenger folders
Working with DCIM system folder and gallery
The DCIM (Digital Camera Images) folder is the standard storage for all photos and videos taken by the camera. Over time, it accumulates bad takes, screenshots and long videos. The MIUI shell has a convenient Recycle Bin feature that stores deleted files for 30 days, taking up space for nothing.
Remember to clean the shopping cart in the Gallery app. Go to the albums, scroll down to "Baskbasket" and click "Clean." It's also worth checking the Screenshots folder inside the gallery, which often stores hundreds of old interface images that are no longer needed.
To fine-tune your photo, use cloud services. Google Photos or Xiaomi Cloud free up space on your device by uploading originals to the cloud and leaving compressed copies on your smartphone, ideal for those who don’t want to sacrifice quality but lack gigabytes.
| Type of file | Location. | Can I remove it? | Recommendation |
|---|---|---|---|
| Photos and videos | DCIM/Camera | Yeah (with backup) | Move to PC or cloud |
| Screenshots | Pictures/Screenshots | Yes. | Remove the old ones |
| Cash browser | Android/data/... | Yes. | Clean through browser settings |
| Downloads. | Download | Yes. | Check for important APKs |
Removal of duplicates and large unused files
When you use your smartphone, you often create copies of the same documents or images, which can happen when you sync with different services or when you crash when you save them, and it's hard to find them manually, so you'd better use specialized duplicate search tools.
Xiaomi’s Explorer app has a built-in duplicate search feature. Click on the menu (three dots or stripes) and select the appropriate item. The system will suggest groups of identical files. Be careful not to delete system files with the same names unless you are sure of their origin.
💡
Before mass deletion of files, always copy important data to a computer or external drive. Accidental deletion of system libraries can lead to unstable software operation.
Also worth paying attention to the Download folder. Browsers and instant messengers often save installation files there. APK, PDF-Regular revision of this folder allows you to free up from 1 to 5 GB of space, as users often forget about downloaded app installers.
Radical Methods: Resetting and Formatting
If the software cleaning methods fail and the memory is refilled in a couple of days, it may be a deep system error or fragmentation of the file system, in which case a complete reset to factory settings helps, which will return the smartphone to the state of "out of the box".
Before you do this, make sure to back up your data via Mi Cloud or locally on your PC. The reset process is irreversible: all contacts, photos, apps and settings will be deleted. Go to Settings → About Phone → Settings Reset → Erase all data.
⚠️ Warning: Make sure the battery is at least 50% battery power before starting a reset. Interrupting the formatting process may result in the inability to boot the operating system (bootloop).
After reset, don't restore all applications from backup, because you can also get back the junk. Install the programs again, only the ones you really need, and keep the system clean and fast for a long time.
💡
Full reset is the most effective way to deal with system debris, but it requires careful backup preparation.
Prevention of memory overflow
To keep the problem of space shortages from returning, you need to develop a habit of regular maintenance of your smartphone. Don't wait for the system to warn you of critical memory levels. Once a month, take 5-10 minutes to check the storage and remove the unnecessary.
Turn off auto-save media files in the gallery for group chats in instant messengers, and this will prevent the gallery from getting clogged with postcards, stickers and commercials that you haven't even viewed, and the privacy and data settings in each instant messenger allow you to flexibly manage this process.
Use microSD cards if your Redmi model supports installation. Transferring photos, videos and music to an external medium is the easiest way to extend the device's capabilities without deleting information. SD-map.
