How to clean memory on Xiaomi Redmi Note 8T: step-by-step instructions

Xiaomi Redmi Note 8T with its 32/64/128 GB of internal memory eventually begins to “suffocate” from the accumulated garbage: temporary application files, duplicate photos, remnants of remote programs and cache of the system eat precious gigabytes. If your smartphone began to slow down, issue notifications about memory shortages or refuse to install updates – it’s time to clean up.

In this article, you will find the latest ways to clean up memory for the Redmi Note 8T (including hidden MIUI features) that run on the firmware versions from MIUI 11 to MIUI 14. We will analyze both standard tools and advanced methods for power users - without the need for root rights or complex manipulations. All instructions are tested on real devices with model features in mind.

1.Diagnostics: What takes up memory on the Redmi Note 8T

Before you start cleaning, it's important to understand which files are eating up space. The Redmi Note 8T has a built-in storage analyzer for this, but it doesn't always show the full picture. Here's how to get accurate data:

Open Settings → About Phone → Storage. Here you will see a diagram of the memory distribution by category: Apps, Images, Video, Audio and Other. Click on each category to see the details:

• 📱 Applications: sorted by size (look for underutilized weight programs) >500MB).
• 📷 Images: includes screenshots, downloads from messengers and duplicate photos.
• 🎥 Video: Often there are unsuccessful recordings or cache TikTok/YouTube.
• 🗑️ Other: the most insidious section - here fall system logs, temporary files and remnants of remote applications.

Note System Data (usually 5-15 GB) if it is larger than 20 GB, it is a sign of a clogged MIUI cache or system errors, and only deep cleaning (see Section 5) will help.

2. Quick cleaning: removing cache and debris

The easiest way to free up 1-3 GB of memory is to clear the app cache and system debris. On the Redmi Note 8T, this is done in a few taps:

1. Go to Settings → Applications → Application Management.
2. Click on the three dots in the top right corner and select Sort by size.
3. Open each application from the top-10 by weight and press Clear cache.
4. For deep cleaning, press Storage. → Clear the data (⚠️ This will reset the application settings!).

To automate the process, use the built-in memory optimizer:

• 🧹 Open the Security app (shield icon).
• 🔍 Go to the Cleanup tab and click Deep Cleanup.
• ✅ Select all items (cache, residual files, advertising debris) and confirm the cleanup.

After this procedure, restart the phone to help the system properly free up the occupied memory blocks. If after cleaning the free space does not appear, check the folder Download (download) and DCIM/.thumbnails (miniature photos), which are often clogged with unnecessary files.

💡

Do not clear the cache for commonly used applications (such as maps or instant messengers) – this will slow them down the next time you run.

3. Removal of duplicates and unnecessary files

One of the main memory eaters on the Redmi Note 8T is duplicate photos that are created when edited in the gallery or imported from other devices.

1. Open the standard gallery.
2. Press three points. → Management → Duplicate.
3. Select all the duplicates found (or leave one copy) and delete.

Also check the following folders (use any file manager, such as Mi File Manager):

Pay special attention to the Android/obb folder, which stores additional game files (such as textures for Genshin Impact or Call of Duty Mobile), if you haven’t played in a long time, these files can be deleted (they will be downloaded again the next time you start the game).

Check backup copies of important data

Make sure that files are not used by apps

4. Application optimization: what can be removed without harm

The Redmi Note 8T preinstalled a lot of Xiaomi system applications that can’t be removed by standard means, but can be disabled or frozen. Here’s a list of safe programs to disable (without risking system stability):

• 🎵 Mi Music is the standard player (replace with Spotify or Spotify) VK Music).
• 📺 Mi Video - Video player (alternative: MX Player).
• 📰 Mi Browser – a browser with ads (use Chrome or Firefox).
• 💼 Mi Pay – payment application (not working in Russia).
• 📡 Mi Remote – Remote (if not used).

To disable the application:

1. Go to Settings → Applications → Application Management.
2. Select the unnecessary application → Disable.
3. Confirm the action (the application will disappear from the menu, but will remain in the system).

To completely remove system applications, root rights or use ADB will be required. If you are not an experienced user, it is better to limit yourself to disabling - this will free up to 1-2 GB of memory and reduce background activity.

5.Deep cleaning: Cache reset and Dalvik

If standard methods haven't worked and memory is still clogged with "invisible debris," it's time for advanced techniques.The Redmi Note 8T has two hidden tools:

1. Cleansing the Dalvik cache (accelerates the system and frees up to 500 MB):

1. Turn off the phone.
2. Press Volume Up + Power to Enter Recovery Mode.
3. Select Wipe & Reset → Wipe Cache (use volume buttons for navigation).
4. Confirm the action and restart the phone.

2. reset MIUI settings (without data loss):

1. Go to Settings → About the phone → Reset settings.
2. Select Reset all settings (this won’t affect files, but will clear your system settings).

These methods are particularly effective if:

• 📉 Free memory disappears after rebooting.
• 🐢 The phone is very slow when opening applications.
• 🔄 The system emits errors when installing updates.

⚠️ Warning: Don't confuse Wipe Cache with Wipe Data in Recovery Mode! The second option will completely reset the phone to factory settings, removing all data.

6. Transfer of data to memory card

The Redmi Note 8T supports microSD cards up to 512GB, which allows you to offload internal memory. However, MIUI has restrictions on porting applications — let's figure out what you can move:

What can be transferred:

• 📁 Photo and video: through gallery settings (Settings) → Warehouse → Save it on. SD-map).
• 🎵 Music and podcasts: in the player settings specify SD-map.
• 📄 Documents: Manually through File Manager.

What can not be transferred (MIUI restrictions):

• 📱 Most apps (except some games with support) SD).
• 🔧 Application data (cache, saves, etc).
• 📱 System updates.

To circumvent restrictions, use the AppMgr app III (It's available in the Play Market, and it allows you to migrate some of the applications to the Play Market. SD-You can check the software after the transfer, and some of them may be making errors.

💡

SD-class A2 (for example, Samsung EVO Plus) will speed up the work of ported applications by 30-40% compared to the class A1.

7. Prevention: How to avoid memory clogging

To avoid having to clean your memory every month, follow these rules:

• 📱 Autocleaning cache: Include in Settings → Warehouse → Autocleaning (remove garbage at low memory level).
• 📷 Photo optimization: In the camera settings, select Save in format HEIF (Files weigh 2 times less than JPEG).
• 🎮 Game Control: In Settings → Annexes → Game management disable background download updates.
• 🔄 Backups: Use Mi Cloud or Google Photos to automatically save photos to the cloud.

We also recommend installing Files by Google, which automatically finds and prompts you to delete:

• 🗑️ Temporary files (.tmp,.log).
• 📁 Empty folders.
• 📄 Old screenshots (over 30 days).

On Redmi Note 8T with 32 GB of memory, it is critical to disable automatic download of media files in messengers (WhatsApp, Telegram). To do this, go to the settings of each application and select Do not download automatically for photo / video.

⚠️ Note: If you are using Redmi Note 8T firmware MIUI Global, check the folder regularly /MIUI/Backup/AllBackup — Backups of weight up to 5 GB created automatically by the system.
