How to Clean Xiaomi Redmi 8T: A Complete Guide to Acceleration

Owners of the popular budget smartphone Xiaomi Redmi 8T often face a slowdown after a year and a half of active use. This is a natural process associated with the accumulation of system debris, fragmentation of the database and overflowing internal memory. Effective cleaning of the gadget can return to its former sharpness of the interface and extend the battery life without the need to buy a new device.

In this article, we’ll look at all the methods available, from quick cleaning with embedded MIUI tools to deep formatting through a computer, and learn how to safely remove viruses, hidden ads, and unnecessary files that slow down the Snapdragon 665 processor. It’s important to understand that a comprehensive approach to software maintenance is often more effective than simply removing applications.

Before you start taking drastic measures, you need to assess the current state of the drive. Often the problem is not the lack of RAM, but the filling of the /data partition with logs and messenger cache. Competent diagnosis will allow you to choose the right tool to speed up your Redmi 8T.

Diagnostics of storage and analysis of occupied place

The first step should always be to review the contents of internal memory. Android requires free space for the correct operation of virtual memory and temporary files. If more than 90% of the volume is occupied, the system begins to work unstable, and applications can fly out.

To start, go to Settings → Memory (or About Phone → Storage) menu, and you'll see a color diagram of the data distribution here. Notice the Other section, which often hides the remnants of remote programs and cache of system processes. Xiaomi's standard analyzer allows you to quickly identify the heaviest folders.

Don't ignore the Android/obb and Android/data folder, which stores cached data from games and heavy apps, but manually delete files from there with care so that the programs don't disrupt the work, and use a built-in cleaning tool that knows the safe ways.

Pay special attention to multimedia files. Duplicate photos taken by different camera applications can take gigabytes. Use the search function for duplicates in the Explorer app or third-party utilities to scan the media library.

Use of the built-in "Security" application

The MIUI shell features a powerful built-in optimization module that does not require additional software installation.This is the most secure way for an ordinary user to clean the Xiaomi Redmi 8T from temporary files. The Security app has access to system partitions closed to third-party cliners.

Launch the app and select Cleanup, and the system will scan and prompt you to remove the cache, APK install packs, and remnants of remote applications, and it is recommended to perform this procedure regularly to prevent the accumulation of “digital fat”.

In the Acceleration section, you can force the background processes that consume RAM to close, but don’t rely on this as a panacea: Android manages the memory itself, and constantly forcing processes to stop can even increase battery consumption when they are restarted.

⚠️ Note: Deep Cleanup may prompt you to delete WhatsApp files.Be careful: when you delete media files from chat rooms, you may lose important documents or photos if they are not saved to the cloud.

Also on the Security menu is the Licenses and Copyright section, which is sometimes bloated due to sync errors. If you notice that this section takes up an abnormally large amount of space, try updating system components via Settings → About Phone → Update MIUI.

Manual cleaning of garbage through the conductor

Automated systems don’t always see the specific garbage left by browsers and social networks. To clean Redmi 8T deeply, you need to look into the root folder of internal memory through the standard Explorer, and you can find folders with the names of applications that have been deleted long ago.

First, check the Download folder. Browsers often save installers there, PDF-Sorting by file size will help you quickly find the heavyweights taking up space.

Messengers create huge archives. MIUI/Gallery/cloud/cache can store cloud gallery sketches; Telegram or WhatsApp folders are worth checking attachments; Telegram videos can be stored for years unless autodelete is configured.

You may need permission to access your system folders, and when you first log in to some sections, Explorer will request access to the files -- confirm it -- and that's necessary to fully manage your smartphone's file system.

Removal of advertising and system debris MIUI

One of the features of the shell MIUI There are advertising modules available (MSA — MIUI Disabling them will not only eliminate pop-ups, but also reduce the load on the processor and network. This is an important step in optimization for Redmi owners. 8T.

To disable ads, go to Settings → Passwords & Security → Access to Personal Data. Find the msa service in the list and turn off the switchboard. The system will ask you to wait 10 seconds and confirm the action. You may have to repeat the procedure 2-3 times, since the server may not respond the first time.

You should also disable personalized ads in your Mi Account settings. Go to Settings → Mi Account → Mi Cloud → Advertising and turn off personalization. This will reduce the number of targeted offers in system applications.

💡

After disabling the msa service, restart the phone, which ensures that all advertising processes are completely stopped and do not remain in RAM.

Be sure to check the settings of specific apps like Music, Video and Explorer. their internal settings often have a separate Receive Recommendations switch that also streams advertising content.

Full reset to factory settings (Hard Reset)

If a software cleanup fails, the most effective way to clean up the Xiaomi Redmi 8T is to completely reset the phone, which puts it back out of the box, removing all user data, apps, and settings, a radical but often the only way to get rid of deep system bugs.

Before starting the procedure, be sure to back up important data. Photos can be synced with Google Photos or Mi Cloud, contacts will be saved in your Google account, and files should be transferred to your computer or flash drive via OTG.

💡

Hard Reset is the only guarantee to remove hidden viruses and miners that could penetrate the system partition of the smartphone.

There are two ways to do a reset. The first is through the settings menu: Settings → About phone → Resetting → Erase all data. This method is convenient if the phone is turned on and running steadily.

⚠️ Warning: Before resetting, make sure the battery is at least 40-50%. Interrupting the data recording process due to battery discharge can damage the bootloader and inability to turn on the phone.

The second method is through Recovery Mode. Turn off the phone completely. Press the Volume Up and Power buttons at the same time. Hold them until the Mi logo appears, then release the power button, keep the volume up. From the Recovery menu, select Wipe Data → Wipe All Data → Confirm.

Once you reboot, you'll see the screen of the initial setup, like when you first turn on a new device, and the system will work as fast as possible, as the file system will be completely free of fragmentation.

Cleaning through computer and ADB (for advanced)

For users who want to get maximum control over Android, there is a method of cleaning through debugging over USB. By connecting Redmi 8T to a PC, you can remove system applications that are not removed in the standard way, freeing up precious megabytes.

First, activate Developer Mode. Go to Settings → About Phone and quickly click on MIUI 7 times. You’ll be a developer notification. Then, in the “Additional” (or “Advanced Settings”) menu, find “Developers” and turn on “Debugging on USB.”

adb shell pm uninstall -k --user 0 com.android.bsp


adb shell pm uninstall -k --user 0 com.miui.analytics

Using ADB commands allows you to remove even system components, such as analytics or Google services, if you don’t need them. However, extreme caution is required here: removing critical system packages can lead to a cyclical restart (bootloop).

To work with ADB, you will need to install Xiaomi USB Driver drivers and Android SDK Platform-Tools platform on your computer. After connecting your phone in debugging mode, run the adb devices command in the command line to make sure the PC sees the device.

Prevention and optimization after cleaning

Once you have cleaned the Xiaomi Redmi 8T, it is important to keep it in good condition.Don't install questionable apps from unknown sources.Use only trusted stores like Google Play or GetApps (with caution).

Update your operating system regularly. Although older models sometimes receive less support, security updates and memory optimization in MIUI patches can make the device work better.

Use “light” versions of apps (Lite) if the phone is still slow. For example, Facebook Lite or Google Go consume significantly less resources than their full-featured counterparts, this is especially true for the Snapdragon 665 processor in 2026-2026.

⚠️ Warning: Do not install third-party antivirus and memory accelerators from Play Market. In Android, they often work worse than the built-in mechanisms and consume resources themselves, slowing down the phone. 8T It's not a one-off thing to do, it's part of the smartphone culture.
