How to Clean Memory on Xiaomi Redmi Note 8 T

The Redmi Note 8 T, released in 2019, is still a popular device due to its excellent price-performance ratio, but owners often face a lack of internal storage. MIUI, with updates and new services, is taking up more space, and modern applications require significant resources to work correctly. If your phone has started to slow down or you can not install the right program, then it’s time to conduct a deep cleaning.

In this article, we will explore not only standard file deletion methods, but also hidden system features that will help free up gigabytes of space. You will learn how to safely remove system debris, transfer data to a memory card and avoid common errors that can lead to the loss of important photos or contact book. Let's start by analyzing what exactly takes up space in your device.

Storage occupancy analysis and search for hidden files

Before you start to take a mindless deletion of everything, you need to know exactly which folders and applications consume the lion's share of resources. Android's built-in tools and MIUI shell provide enough tools for initial diagnosis, but they don't always show the full picture. It often turns out that half of the memory is not occupied by installed games, but by the messenger cache and forgotten downloads.

To start, go to the settings menu and select About Phone → Storage. Here you will see a color diagram showing apps, images, videos and system files in different colors. Pay special attention to the Other section, which often hides temporary update files and remnants of deleted programs. By clicking on each sector, you can go to a detailed list of files.

Special attention should be paid to the MIUI folder at the root of internal memory, which is where error logs, voice recorder backups and temporary gallery files are stored. The system analyzer may not show this data as taking up much space unless you manually check it. Regular monitoring allows you to notice anomalous growth in data volume in time.

Use of the built-in "Security" application

Each Xiaomi smartphone has a security system app pre-installed, which includes a powerful garbage cleaner, the first line of defense to use before connecting third-party utilities, and the program's algorithm is tailored to the specifics of the MIUI shell, allowing it to safely delete temporary files without risking damage to the system.

Launch the app and click on the Clean button. The scanner will analyze the device and suggest removing the cache, advertising files and uninstall packet residues. However, standard cleaning is often superficial. For a deeper analysis, click on the basket icon in the top corner or select Deep Clean from the tool menu.

⚠️ Note: In the Deep Cleanup section, carefully check the file list before deleting. The system may flag as trash screenshots you planned to save or small video files important to you.

WhatsApp Cleanup inside the app allows you to selectively remove old videos and images from correspondence, freeing up gigabytes of space. This is especially true for owners of Redmi Note 8 T, since messengers tend to grow to exorbitant size. Regular use of this tool prevents critical overflow of memory.

💡

Run the cleanup via the Security app immediately after the phone restarts, which will remove more temporary files that are not used by active processes.

Manually cleansing app and social media cache

The most voracious consumers of memory are traditionally social networks and instant messengers. Telegram, VK, Instagram and YouTube store the videos and images viewed in cache to quickly upload them when re-watched. Over time, this cache can take up to 10-15 GB, which is a critical volume for a model with 64 GB of internal memory.

To clear the cache of a particular application, go to Settings → Apps → All apps. Find the program you want (like YouTube) in the list and select Memory. There you will see two buttons: Clear cache and Clear all. The first one deletes temporary files, the second one resets the application to a state immediately after installation, requiring you to log in again.

• 📱 Telegram: Better to clean through the settings of the application: Settings → Data and memory → Use of memory → Clear the cache. You can set up auto-delete media files there.
• 📸 Instagram: Android is not cleaned properly, often requires removal and re-installation of the application to completely reset the bloated cache.
• 📹 TikTok: In the application settings there is a “Free space” item that allows you to delete temporary files and drafts.

It's important to understand the difference between cache and user data. Cache cleaning is safe and won't delete your emails or logins. Cleanup will completely remove your account from the app, and you'll have to re-enter your password. Be careful when choosing an action, especially if you don't remember passwords from all your accounts.

Working with the file system and the download folder

Download folder is the black hole of any smartphone. Browsers, instant messengers and email clients by default save all downloaded files there. APK-installer, PDF-documents, saved images from web pages – all this can lie dead for years, occupying precious megabytes.

Open standard Explorer Explorer (or download Files by Google) and go to Downloads. Sort files by size or date. You'll be surprised to find installation files for applications you've installed for a long time or older versions of documents. Delete files with the.apk extension boldly if you don't plan to reinstall applications manually.

Don’t forget to check the Bluetooth folder if you’ve ever transferred files using this protocol. Also worth a look at the Tencent and MicroMsg folders (for WeChat users or older versions of QQ), which often store duplicate images. Deleting the Android/data folder requires caution, since it stores game cached data and offline navigator maps.

Transferring data to memory card and cloud services

The Redmi Note 8 T features a hybrid slot that allows microSD memory cards to be used, a lifeline for those who store a lot of media, and the transfer of photos and videos to an external medium frees up internal memory, which is critical for system performance and application installation.

To transfer files, insert a memory card, wait for its definition and open Explorer. highlight the desired photos and videos (usually they are in folders). DCIM and Pictures), click "Move" and select the path to SD-After transfer, make sure to check if files from the new card are opened before deleting the originals.

An alternative to a physical map is cloud storage, such as Google Photos, Yandex.Disk or MI Cloud. Set up automatic sync of the gallery to the cloud. Once the photos are uploaded to the server, use the "Free space" function in the cloud application, which will delete local copies, leaving only thumbnails.

⚠️ Note: When formatting a memory card for internal storage, all data on it will be permanently deleted. Be sure to back up important files to your computer before starting the procedure.

Resetting settings as a radical cleaning method

If none of the above methods yielded the desired result and the memory of the Redmi Note 8 T is filled again in a mysterious way, it is possible that the system has accumulated critical errors or virus software. In this case, the solution will be a complete reset to the factory settings (Hard Reset), which will return the phone to the state of “out of the box”.

Before starting the procedure, be sure to back up all important data, as all contacts, messages, photos and installed apps will be deleted in the process. Go to Settings → About Phone → Reset → Erase all data. The phone will restart and begin the cleanup process, which can take 10-15 minutes.

After reset, don't rush to restore all the apps from Google backup. Try using a clean phone for a couple of days. Often, it turns out that one particular app created the problem, which you can safely avoid re-installation, which will help avoid a repeat of the space shortage situation.

💡

Hard Reset is the only way to ensure that all system debris and hidden file system errors are removed, but it requires a mandatory data backup.
