Xiaomi’s Redmi Note 8 has proven itself to be a reliable device, but over time, even 64 or 128 gigabytes of built-in storage may run out.It’s an inevitable process of digital debris accumulation that slows down the MIUI system. Users often notice the phone starts to “slow down,” apps open longer, and space-short notifications appear at the most inopportune moment.
A crowded drive affects not only the speed of writing new data, but also the overall stability of the operating system. When less than 10% of the total is free, Android has difficulty performing background processes. In this article, we will discuss proven methods to help restore the device to its former aspiration and free up precious space.
Don't rush to delete important documents or favorite photos. There are more subtle cleaning tools that don't require personal information to be sacrificed. A sound approach to file management will allow the Redmi Note 8 to be used as efficiently as possible over time.
Analysis of vault occupancy
Before you start doing something, you need to understand what's taking up space, and there's a powerful analyzer built into the MIUI shell that visually displays the distribution of data, and it divides memory into categories: applications, images, videos, documents, and so on.
Sometimes users are surprised to find that the lion’s share of space is occupied by messengers. Telegram and WhatsApp have a habit of saving all the received media files to the gallery, even if you have never opened them, which creates the effect of “bloating” memory without the owner’s knowledge.
To start, go to the settings and find the "About Phone" item, which will display general statistics, the built-in "Security" app provides more detailed information. Click on the "Clean Up" icon, and the system will scan.
⚠️ Warning: Do not delete files from system folders that you do not know the purpose of, which can lead to unstable interface operation or loss of settings.
Note the Other section, which often hides remnants of deleted programs or temporary update files. The MIUI system partition can take up to 15 GB, which is the norm for modern firmware versions, but overblowning this partition requires resetting.
Use of the built-in "Security" application
Xiaomi’s standard tool is the first line of defense against digital trash, which can find app cache, advertising files, and remnants of remote programs, and it takes only a few seconds to run a scan and gives instant results.
In the Cleanup section, you'll see recommendations for deleting temporary files, the system itself marks safe-to-delete objects, but you should be careful: sometimes there are saved drafts or offline maps.
☑️ Daily cleaning
And it's a special feature called Deep Clean, which analyzes folder content in more detail, looking for duplicate photos and large files you might have forgotten, and it's a great way to find gigabyte-long heavyweights.
And remember, the Apps tab, where you can sort programs by size of space, and it often turns out that some rarely used application has grown into an obscene size because of the cache it has accumulated.
💡
Check the Recycle Bin section in the gallery and file manager regularly, and deleted files are stored there for 30 days and continue to take up space.
Cleaning the cache and application data
Cache is temporary data that speeds up programs but eventually turns into ballast. Social media, browsers, and streaming services can accumulate gigabytes of this garbage. Cache cleaning is safe and doesn't delete your logins or emails.
To do this manually, go to Settings → Apps → All apps. Select the program you want, like YouTube or Instagram, and click Memory. There will be a button to Clear Cache.
There's a difference between clearing the cache and cleaning the data. If you choose Clear All, the application will return to state immediately after installation. All passwords, settings, and stored correspondence will be deleted. Use this feature only if you want to completely reset the program or delete it, but you can't do it in the standard way.
| Type of data | What's removed | Secure for the account. | Recommended frequency |
|---|---|---|---|
| Cash. | Temporary files, thumbnails | Yes. | Once a week. |
| Application data | Logins, settings, database | No (re-entry needed) | When there is a failure |
| Cookies | Tracking sites, auto-save | Yeah (deleted accounts) | Once a month |
| Download history | Downloaded installers, documents | Yes. | As you fill up |
The messaging app itself has a Data and Storage section in its settings where you can remove old backups or media files from specific chats, which often frees up more space than a standard system cleanup.
💡
Clearing the cache does not delete your personal correspondence or photos, it only deletes temporary files to speed up the work.
Working with multimedia and gallery
Photos and video are the main consumers of memory on any modern smartphone. The Redmi Note 8 camera takes high-quality pictures that weigh a lot, especially if high-resolution or slow-motion video is enabled.
Use cloud services to automatically sync. Google Photos allows you to store your images in the cloud, freeing up space on your device with a single “Free Space” button. Once downloaded, the originals are deleted from your phone, but remain available in the gallery over the Internet.
The MIUI file manager has a convenient duplicate search function. Often we take a series of identical shots to choose the best one, and the rest of them lie dead for years. Deleting serial shooting and similar frames is a quick way to win several gigabytes.
⚠️ Before mass deletion of the photo, be sure to check the cloud storage or computer. It is impossible to recover files deleted from the cart (after 30 days) without a backup copy.
Also check the DCIM →.thumbnails folder. This is a hidden folder where you store thumbnails for the gallery. Sometimes it can be as large as 2-3 GB. You can clean it through the file manager by enabling the display of hidden files, but it will fill again the next time you open the gallery.
Hidden trash folders
Removing unnecessary apps and games
Apps tend to accumulate. We install the program, use it once, and forget. On the Xiaomi Redmi Note 8, each resident takes up space not only with their installation file, but also with their data.
Do a software audit. Go to the app settings and sort them by size. Games often weigh more than 1-2 GB. If you haven't played them for months, it's easier to uninstall and download them again than to store them on your phone.
Notice the pre-installed applications that can't be removed in the standard way, and you can "disable" them, which will hide the icon and prevent the program from running in the background, although it will take up minimal space on the disk (only the system package).
For advanced users, there is the option of removing system debris via ADB (Android Debug Bridge), which requires a computer connection and commands, but allows you to get rid of unnecessary services from Google or Xiaomi that can not be removed otherwise.
adb shell pm uninstall -k --user 0 com.google.android.videosThis team, for example, will remove Google Play Movies if you don't need it. Be extremely careful with ADB teams, only removing what you're 100% sure of.
Transfer data to memory card and cloud
If internal storage is critically scarce, consider using a microSD card. Redmi Note 8 supports cards up to 256 GB. It is the perfect place to store photos, videos and music.
In the camera settings, you can immediately set the saving of new images to the memory card, and many file managers allow you to transfer existing Download or Movies folders to an external drive.
💡
Use UHS-I or higher speed memory cards, and slow cards can cause delays when shooting high-resolution video.
Cloud storage is a modern alternative to physical maps. Google Drive, Yandex.Disk or Mi Cloud allow you to transfer documents and archives to the Internet. Xiaomi account Mi Account gives 5 GB for free, which is enough for important documents.
Use of the OTG-And the cable is another life hack, and you can plug a simple flash drive into a Type-C connector and put heavy files on it, freeing up the internal space, and it's convenient for temporary archival storage.
Radical measures: Resetting to factory settings
If no methods help and the memory fills up on its own, there may have been a logical failure in the system, in which case a complete reset helps, which will return the phone to a state of "store-like".
Before this procedure, make sure to make a full backup. The reset will delete everything: contacts, SMS, photos, apps and settings. Make sure that sync with your Google account is successful.
To reset, go to Settings → About Phone → Settings Reset → Erase all data. The process will take a few minutes, after which the phone will restart and prompt you to set it up again.
⚠️ Warning: Make sure the battery is at least 50% battery power before starting reset. interruption of the process during the formatting phase may cause software to break down.
Once reset, you'll see a significant increase in memory and speed, and you'll be stripped of the accumulated debris over the years, and this is the most efficient, if laborious, way to reanimate the Xiaomi Redmi Note 8.
💡
Hard Reset is a last resort that solves 99% of memory problems but requires a mandatory backup.
