How to Clean Xiaomi Redmi 8T: 5 Ways to Get Back the Speed

The Xiaomi Redmi 8T is still a popular budget smartphone, but over time even it starts to slow down, usually due to cache, background debris and outdated files. This article will help you figure out how to clean up memory, delete unnecessary data and optimize the device without resetting to factory settings. We will look at both standard methods through settings and hidden MIUI features that many people do not know about.

It’s important to understand that Redmi 8T runs on MIUI (usually 11-12) and the cleaning algorithms are different from pure Android. For example, the built-in Security tool doesn’t remove all types of debris, and some system files are best left unattended so as not to disturb stability.

If you've never cleaned your smartphone yourself, start with the first two sections. Power users can jump straight to deep cleaning or manual techniques. And at the end of the article, answer frequent questions and life hacks to keep the Redmi 8T running in the long run.

1. Quick cleaning through built-in MIUI tools

The easiest way is to use the standard MIUI features. They don't require root rights and are suitable for regular cleaning. Redmi 8T has two key tools: Optimization and Cleanup in the Security app.

To get them going:

• 📱 Open the Security app (Icon with shield).
• 🧹 Press Cleanup. → wait for the analysis → Select Clean (deletes app cache, temporary files, residues) APK).
• ⚡ Return to the home screen Security and tap Optimization → Accelerate (close background processes).

This will free up 1-3 GB of memory and temporarily speed up the phone, but it doesn’t delete deep system files or the Google Play Services cache, which often inflates to hundreds of megabytes.

⚠️ Warning: Do not use the Deep Clean in Security feature – it aggressively deletes application data, which can cause settings to go wrong (for example, in WhatsApp or banking programs).

2. Manual cleaning of the app cache

Many apps (especially social networks and instant messengers) accumulate gigabytes of cache that is not removed by standard cleaning. Redmi 8T can manually clean the cache for each application separately – this is safe and does not delete personal data (photos, correspondence, etc.).

Instructions:

1. Go to Settings → Applications → Application Management.
2. Select an app (such as Facebook or YouTube).
3. Press Warehouse. → Clear the cache.
4. To clean up completely, tap Space Management → delete unnecessary files (e.g. uploaded videos to Telegram).

Pay special attention to these applications - they most often "clog" memory:

• 📸 Galery (miniature photos, edited copies).
• 🎵 Music or Spotify (cached songs).
• 🌍 Google Maps (offline maps, route cache).
• 💬 WhatsApp/Telegram (Media files, stickers).

On Redmi 8T, Google Play Services cache can take up to 1-2 GB. Its cleaning will not hurt, but after that, the first launches of applications will be slower (cache is recreated).

3. System debris disposal through Recovery

If the phone is slowing down a lot and standard methods don't work, try cleaning through Recovery Mode. This method removes temporary system files that you can't see in the normal interface. Importantly, it doesn't affect user data (photos, contacts), but it will reset some settings (for example, background wallpaper).

Step-by-step:

1. Turn off Redmi 8T.
2. Press Volume Up + Power before the MI logo appears.
3. From the Recovery menu, select Wipe & Reset → Wipe Cache (use volume buttons for navigation, power for selection).
4. Confirm the action and wait for the completion.
5. Reboot the phone (Reboot) → Reboot to System).

This method is particularly useful if:

• 🐢 Phone hangs on loading.
• 🔄 Applications are closed spontaneously.
• 📉 Free memory less than 1 GB (even after standard cleaning).

⚠️ Warning: Do not choose Wipe Data in Recovery – this will lead to a complete reset of the phone before the factory settings!

4.Memory optimization with ADB (for advanced)

If you are ready to use a computer, ADB (Android Debug Bridge will help remove hidden debris that is not available through normal settings. USB-Debugging and basic command line knowledge, but gives maximum effect.

What you need:

• 🖥️ Computer with installed ADB Tools.
• 🔌 USB-cable (preferably original).
• ⚙️ Included Debugging by USB on the phone (Settings) → The phone. → Version. MIUI → 7 times tap the version → Come back to the extra. → For developers).

Cleaning commands (enter cmd or terminal):

adb shell pm clear com.miui.securitycenter #Cleaning up the Security cache


adb shell pm clear com.android.vending # Google Play Market Cleanup




adb shell pm trim-caches 500M # Forced cache clearing of all applications

After you've done the commands, restart the phone.

• 🗑️ Remnants of Remote Applications.
• 📁 Cache of system services (Google Play Services, MIUI Daemon).
• 🔄 Temporary update files.

⚠️ Note: The pm clear command for some applications (such as WhatsApp) will remove not only the cache, but also the settings.

💡

If after cleaning through ADB the phone became slower, follow the command adb shell cmd package bg-dexopt-job - it optimizes the work of background processes.

5. Cleaning with third-party applications

If you don't want to mess with manual settings, you can use specialized utilities. Redmi 8T will suit:

How to choose the right one:

• 🔍 For deep cleaning — SD Maid (will find even hidden files).
• 📱 For quick optimization – Files by Google (remove unnecessary photos and videos).
• 🛡️ To protect against viruses – Clean Master (but use carefully).

Before using any cleaner:

1. Make a backup copy of important data.
2. Don’t settle for “acceleration” through Boost – it just removes processes from memory, but doesn’t clean files.
3. Turn off the autocleaner – it can delete the necessary data.

💡

Side cleaners don't replace manual cleaning! They don't remove the cache of MIUI system applications, so use them as an addition to standard methods.

6 How to prevent future memory clogging

To prevent the Redmi 8T from brake again in a week, follow these tips:

• 📵 Limit background activity: Go to Settings → Battery → Power management applications and select Limit background activity for unnecessary programs.
• 🚫 Turn off auto-update apps: Google Play → Settings → Auto-update of applications → Never.
• 🗃️ Transfer files to memory card: in Settings → Configure the storage of photos and videos on microSD.
• 🔄 Regularly reboot your phone (every 2-3 days) – this clears the RAM.

Also useful:

• 📶 Disable mobile data for applications that do not use it (Settings) → SIM-maps and mobile networks → Transfer of data).
• 🔋 Watch the temperature of the phone – overheating accelerates memory wear.
• 🛠️ Check the settings once a month → Warehouse → Analyze and delete unnecessary files.

If you install/remove apps frequently, use Lite versions (e.g. Facebook Lite, Messenger Lite) – they take up 2-3 times less space.
