Owners of the popular Xiaomi Redmi Note 8 T smartphone sooner or later face unpleasant notification of a shortage of space.This device, released in 2019, originally offered options with 64 or 128 gigabytes of internal memory, which seemed impressive at the time of release. However, modern applications, high-quality photos and messenger cache eat gigabytes at an alarming rate, making the system run slower.
Fortunately, the MIUI software shell provides users with powerful tools to manage storage, allowing them to significantly extend the life of a gadget without buying a new one. In this article, we will examine proven methods for cleaning up system debris, transferring data and optimizing the operation of the drive, you will learn how to safely vacate space without removing important contacts and documents.
Before you start taking drastic measures like resetting, you need to do a thorough review of what exactly takes up space. Often, half the memory is occupied by duplicate photos or long-forgotten videos. A competent approach to organizing files will allow you to increase the available volume on the Redmi Note 8 T by many times.
Analysis of storage occupancy and search for hidden volumes
The first step to optimizing your smartphone should be detailed diagnostics. The standard Android settings menu often shows the big picture, hiding details. You need to go to Settings → Memory to see the visualization of occupied space. The system automatically categorizes files into categories: applications, images, video, audio, etc.
Pay special attention to the Other section, which often hides messenger cache files, remnants of deleted programs and temporary system logs. Sometimes this partition can grow to 10-15 gigabytes, which is a critical volume for the Redmi Note 8 T with the basic version of memory. Ignoring this category negates all attempts at cleanup.
For a deeper analysis, you can use built-in Explorer or third-party utilities to show the size of each folder at the root of the file system, which can help you find forgotten downloads or heavy files left after a firmware update. Understanding the folder structure is the key to effective resource management.
It's worth noting that the Android file system is designed so that even after deleting a file, the space isn't always freed up instantly. The gallery cart or cloud syncs can store remote objects for another 30 days. Check these locations to make sure that the deletion is complete.
Cleaning the cache and removing system debris
The safest and fastest way to increase the available space is to use the built-in Security tool. Every Xiaomi smartphone has an app preinstalled that scans the device for temporary files. Run a scan and press the Clean button to remove megabytes of useless garbage.
However, standard cleaning often only affects the surface cache. For a deeper cleaning, you need to go to the settings of specific applications. For example, social networks and browsers accumulate gigabytes of data. Go to Settings → Apps → All applications, select the desired application (for example, Chrome or VK) and click Clear → Clear cache.
⚠️ Warning: Don’t confuse the Clear Cache button with the Delete Data button. The second option will completely delete your account, correspondence, and in-app settings, returning it to state immediately after installation.
Special attention should be paid to the DCIM folder and hidden folders at the root of internal memory, which may be left with thumbnails of deleted photos or.thumbnails files that weigh a lot, which are safe to delete, the system will create them again if necessary, but this will free up valuable gigabytes.
☑️ Daily Memory Hygiene
Regularly doing these simple steps will prevent critical memory filling. If you are actively using the browser, it is recommended to set up automatic cleaning of history and cache when you leave the application, this will keep the Redmi Note 8 T performance at a high level.
Working with a microSD memory card on the Redmi Note 8 T
One of the main features of the Redmi Note 8 T is the presence of a separate slot for a microSD memory card, which does not conflict with the second one. SIM-It's a huge advantage, so you can physically increase the storage capacity, but in order for the system to work properly, the memory card needs to be formatted and configured properly.
Modern versions MIUI This allows you to use the memory card as an internal storage (Adoptable Storage), although this feature is often hidden. In standard mode, the card works as a portable storage. SD-This will instantly unload the main drive.
When choosing a memory card for Xiaomi, it is important to pay attention to the speed class.The minimum recommended standard is Class 10 or UHS-I. Using slow cards will cause applications to work with delays, and recording high-resolution video can be interrupted.
| Type of card | Recording speed (min) | Recommended use | Compatibility with 4K |
|---|---|---|---|
| Class 4 | 4 MB/s | Music, documents | No. |
| Class 10 | 10 MB/s | Photo: Full HD video | No. |
| UHS-I (U1) | 10-30 MB/s | Applications, games | Partially. |
| UHS-I (U3) | 30+ MB/s | 4K video, heavy games | Yes. |
Once you have the card installed, the system will suggest formatting it, and remember that formatting will delete all the data on the media, so save important files to your computer beforehand, and after you have finished the procedure, a new section will appear in the Memory menu where you can manually transfer files.

Optimization of messengers: Telegram and WhatsApp
The leaders in memory consumption in any smartphone, including the Redmi Note 8 T, are instant messengers. WhatsApp and Telegram by default save all received photos and videos to the phone gallery, creating duplicate files. This happens unnoticed by the user and quickly clogs gigabytes.
To solve the problem on WhatsApp, you need to go to chat settings and turn off the visibility of media in the gallery, as well as limit autoload. On Telegram, the situation is even more serious: the application caches all the files viewed. Go to Settings → Data and memory → Memory Use and set the cache storage period, for example, “3 days” or “1 week”.
Turn on the automatic cache cleaner. This is a critical setting that will self-delete old files viewed, making room for new ones. You no longer have to manually clean folders with GIFs and mugs.
⚠️ Note: When enabling auto-cleaning in Telegram, make sure that important working documents you have previously saved to Favorites or to a cloud drive, otherwise they can be deleted without the possibility of recovery.
It’s also worth checking the download folders inside instant messengers. Often users get files that are no longer needed, but they continue to lie in the device’s memory for months. Regular cleaning of the Documents and Music tabs inside apps gives a noticeable increase in free space.
💡
Use the Archivation feature on WhatsApp before cleaning if you fear losing important correspondence, which will create a backup on Google Drive that can be restored on a new device or after reinstalling the app.
Using Cloud Storage and Streaming
In the era of cloud technology, storing terabytes of information locally on a smartphone is becoming impractical. Services like Google Photos, Yandex.Disk or Mi Cloud allow you to upload media files to the Internet, leaving only thumbnails on the device, which frees up huge amounts of memory on the Xiaomi Redmi Note 8 T.
Set up automatic sync with the cloud. Once the original photos are successfully uploaded, the service will suggest removing them from the device, leaving them available for viewing in high quality over the network, and for everyday viewing, this is enough, and space will be vacated.
The same approach applies to music or movies: instead of downloading albums and TV shows to your phone, use streaming services (Yandex.Music, Spotify, Netflix) that allow you to listen to and watch content online or download it temporarily, with the possibility of automatic deletion after listening.
Google Photos also has a “Free Space” feature that automatically finds and deletes copies of photos and videos already stored in the cloud on your device, one of the most efficient quick-cleaning tools available to every Android user.
Radical measures: Resetting and reflashing
If the software cleaning methods don’t help and the system keeps writing about memory shortages, it’s possible that the file system is damaged or too much system debris has accumulated that can’t be removed by regular means, in which case a full factory reset helps.
Before doing this, make sure to back up all your data, as everything will be deleted in the process: contacts, SMS, apps and files. Reset will return the Redmi Note 8 T to a “store-like” state, which is guaranteed to free up maximum memory.
To perform the reset, go to Settings → About Phone → Settings Reset → Erase all data. The process will take a few minutes, after which the phone will restart. This will also eliminate many software errors and speed up the interface.
💡
Full reset is the only way to ensure that you remove system debris and fragmented files that have accumulated over the years of use and are not removed by a routine cleaning.
In some cases, if the problem lies in the errors of the operating system itself, you may need to flash the device through the computer using the Mi Flash Tool utility. This is a more complex process that requires unlocking the bootloader, but it allows you to completely install the latest version of MIUI, eliminating any software conflicts.
