Modern smartphones Xiaomi, Redmi and POCO They have impressive performance, but even a powerful processor can't save you from the brakes if the internal storage is full. 90-95%, The Android operating system starts to run unstable, apps crash, and the camera may refuse to take pictures, because the system does not have enough space to create temporary files and buffer processes.
Many users mistakenly believe that deleting multiple photos will solve the problem, but system debris often takes up much more space than it first seems. In this article, we will examine proven ways to free up space that do not require root rights and allow the device to return to its previous speed.
You will learn how to safely delete unnecessary data, clean the app cache, and use the hidden features of the MIUI or HyperOS shell. Proper file organization is the key to keeping your gadget running long and fast without having to buy a new model.
Analysis of occupied space through standard means
The first step should always be diagnostics, and Xiaomi owners are more fortunate than many other brands, because the shell already has a powerful memory analysis tool built in, which allows you to visually assess what is eating up gigabytes of your storage.
To run the utility, you need to go to the Settings menu and select About Phone. Next, click on Memory or immediately start the Security application, which is on the desktop by default. In the Cleanup section, the system scans the device and gives a report.
The interface will show you the distribution of space by category: apps, images, videos, documents, etc. Notice the “Other” section, which often contains hidden messenger caches and residual files of remote programs.
💡
Use the Cleanup widget on your desktop for quick access to memory analysis without diving deep into the settings.
Don’t be in a hurry to delete everything when you see a red occupancy scale. First, examine the contents of the folders, since in the Documents section there may be important files, and in Downloads there are application installers that are no longer needed.
Using the built-in “Conductor” application and cleaning up garbage
The standard file manager from Xiaomi is able not only to open files, but also to find duplicates, large files and APK installation packages. This is one of the most effective ways to quickly clean without third-party software.
Open Explorer and scroll down to the Analysis section (or simply Cleanup) and the system will prompt you to delete temporary files, ads and installer packages, often freeing up 2 to 5 GB of space.
- 🗑️ Removal APK: After updating applications, installation files are no longer needed and take up space.
- 📦 Large files: Find videos or archives larger than 100MB that you accidentally downloaded.
- 📸 Algorithms will find serial shots, of which you can leave only the best.
The Download folder is a place where browsers and messengers default to all attachments, often accumulating gigabytes of forgotten presentations, memes and product catalogs.
☑️ Weekly cleaning through the conductor
After manually checking large files, go back to the main Explorer menu, and there is often a separate button to clear the system cache, which is safe to delete and does not affect the operation of installed programs.
Cleaning up cache and data heavy applications
The most voracious consumers of memory are traditionally social networks and instant messengers. Telegram, Viber, Instagram and TikTok save thousands of thumbnails, videos and audio files, turning from a light app into a monster that takes up 10-20 GB.
To clear them, go to Settings → Apps → All apps. Select a heavy app and press Memory. Here you will see two buttons: Clear cache and Clear all (or Reset). Cache deletes temporary files, which is safe. Data deletes logins, passwords and correspondence, so you need to be careful with this option.
| Type of cleaning | What's removed | Secure for the account. | Recommended frequency |
|---|---|---|---|
| Clearing the cache | Temporary files, thumbnails | Yeah, totally. | Once a week. |
| Clearing the data | Logins, settings, correspondence | No, we need to go back in. | Only when it fails. |
| Deletion of the annex | All program files | No, the profile is deleted. | If necessary, |
| Cleaning inside the application | Chat media files | Yeah, if there's a backup. | Once a month |
In Telegram, for example, it’s better to use the built-in cleanup function. Go to Settings → Data and memory → Memory Use and set automatic cache deletion after 3 days or a week. This will prevent the application from growing in the future.
⚠️ Warning: Before clicking the Clear All button (data), make sure you remember your account password, otherwise you may lose access to your correspondence without the ability to recover.
Work with gallery and cloud storage
High-resolution photos and videos are the enemy of free memory: Xiaomi’s current cameras shoot in 4K or take pictures weighing 5-10 MB each, a thousand of which easily take up 10 GB of space.
Use the Recycle Bin feature in the gallery. Many users delete photos but forget that they stay in the cart for another 30 days, continuing to occupy space. Go to the albums, find the Deleted folder and clean it completely.
Set up sync with Google Photos or Mi Cloud. Once photos are uploaded to the cloud, use the Free Space feature in the cloud service settings, which will remove the originals from your phone, leaving them available for viewing over the Internet.
If you’re shooting a lot of videos, consider changing your camera settings. 1080p resolution is often enough for everyday shooting, whereas 4K or 8K should only be turned on for important events. Also turn off RAW mode if you’re not a professional photographer, as such files weigh 10 times more than regular JPEGs.
Delete system updates and residual files
The MIUI and HyperOS shell like to download updates in the background. If you have manually updated or the system has downloaded a package but the installation has not yet been made, the firmware file can lie in memory and take 3-4 GB.
Find the folder. downloaded_rom If you have already upgraded or you don't need an update, this file can be safely deleted. It is an archive with a new version of the system.
- 📂 folder MIUI: At the root is often a folder with logs and error reports that can be deleted.
- 📱 Remnants of Remote Games: Check the folder Android/data To find folders from games you have already deleted.
- 🎵 Offline maps: Navigators often store maps of cities you visited once.
⚠️ Be very careful when cleaning the folder. Android/data. Remove only those subfolders whose names correspond to already remote applications, otherwise the program may stop working correctly.
It's also worth checking the thumbnails folder in the DCIM directory, which is thumbnails of your photos, and the system creates them for quick viewing in the gallery, and if they're larger than 1 GB, you can delete the contents of the folder, and the system will recreate them, but that will make room right now.
Expanding memory by means of SD-maps USB-OTG
If internal storage is physically small (such as 64 GB), no cleaning will help forever, in which case the only solution is to transfer data to external media. Most Redmi and budget Xiaomi models have a microSD card slot.
Install a high-speed card (at least Class 10 or U3), and once installed, the system will suggest using it as internal memory or portable storage, and for photos and videos, choose the second option, so that files do not disappear when you extract the card.
What to do if there is no card slot?
Configure the camera and voice recorder so that they save files to the default SD-This is done in the settings of the Camera app itself, and in Telegram and WhatsApp, you can save media files to an external drive.
Transfer your files to your computer regularly. Connect your phone to your PC once a month via cable and copy DCIM and Pictures folders to your hard drive, which is the most reliable way to save important memories and keep your phone on track.
