How to Clean Xiaomi Redmi Note 8T: The Complete Guide

Smartphones series Redmi Note deservedly considered popular, but even the powerful processor Snapdragon 730G eventually begins to stumble on the crowded internal memory. If your Xiaomi Redmi Note 8T began to work slower, and notifications about the lack of space appear more often, then it’s time for a cleanup. accumulated digital garbage is not only gigabytes of forgotten screenshots, but also hidden logs, remnants of remote programs and bloated cache of messengers.

In this article, we will explore not only standard cleaning methods through built-in MIUI tools, but also deeper ways to free up space, which are often ignored by users. Proper file system maintenance can extend the life of the device and return it to its previous interface response speed.

Before embarking on radical measures such as factory resets, it is worth trying a comprehensive software cleaning process that requires no root rights or special knowledge, but requires careful deletion of system files.

Memory Occupancy Analysis and Hidden Files Search

The first step is always diagnostics. The standard storage analyzer in MIUI often shows only the big picture, hiding the real gigabyte eaters. To understand what takes up space, you need to look deeper than standard settings. It often turns out that the lion's share of memory is not the installed applications, but their data.

Use the built-in Explorer tool to manually search for heavy folders, especially social networking directories and messengers like Telegram or WhatsApp, which are the default apps that store all received media files, creating duplicates in the gallery and taking up precious space.

For more detailed analysis, you can use third-party utilities that visualize the file system as a diagram, which allows you to instantly identify forgotten downloads, old archives or remnants of remote games.

⚠️ Warning: When manually deleting files at the root of the system or in the Android folder, be extremely careful.Deleting system libraries can lead to malfunctioning of the Redmi Note 8T cyclic-reset.

• 📂 Download folder - installations are most often accumulated here APK-Files and documents that are no longer needed.
• 📸 Directory DCIM — Check for high-resolution video that can be transferred to a cloud server.
• 🗑 Hidden folder.thumbnails – a cache of miniatures of the gallery, which can grow to several gigabytes.

Cleaning the cache of applications and system debris

The easiest and safest way to free up space is to use the regular Security app, which is pre-installed on all Xiaomi smartphones, which can find temporary files, installer residues and advertising debris, but automatic cleaning is not always effective against the cache of heavy applications.

For deep cleaning, you need to manually manage the cache of each application. Go to Settings → Applications → All applications, select the leader program for memory consumption (for example, browser or social network) and click Clear cache. It is important not to confuse this button with the Clear data function, since the latter option will completely reset the application to the state of the first installation, removing logins and settings.

The system update cache is another hidden memory reserve, and once the MIUI update is successfully installed, the older files can remain in the system, and deletion is safe if the phone is stable after the update.

Regular prevention helps avoid critical memory filling, and if you notice that after cleaning the place again quickly ends, you should check the settings for automatic media saving in messengers.

💡

Turn off auto-save photos and videos in Telegram and WhatsApp settings, which will prevent duplicate files in the gallery and save up to 30% of space in the long run.

Removing duplicates and heavy media files

Multimedia content is the main enemy of free space on the Redmi Note 8T. The camera of the smartphone takes great pictures, but RAW files or 4K videos take up hundreds of megabytes each.

MIUI has a built-in duplicate search feature, but it doesn't always work perfectly, so you'd better use a file manager with a similar image search function, so you can quickly select a series of images and leave only the best ones, removing the rest.

It's also worth checking the Recycle Bin folder in the gallery. Deleted files are stored there for 30 days, continuing to take up space. Cleaning the Recycle Bin is an instantaneous release of space that many forget.

Working with Android folder and residual files

When apps are removed, there are often tails left in the system — folders with logs, temp data, and settings — that can be in the root of internal memory or in the Android/data system directory. On modern Android versions, access to this folder is limited, but file managers like CX File Explorer or the regular Explorer let you look in.

Look for folders with names of remote games or programs. For example, if you delete a heavy game, its cache can weigh 2-3 GB and lie dead weight.

Pay special attention to the MIUI/Gallery/cloud/cache folder, which can store thumbnails of the cloud gallery, which take up space even if the originals are already in the cloud.

⚠️ Note: Do not delete folders with the names of system services of Google or Xiaomi (for example, com.google.android.gms) if you are not sure about their purpose.

Using Developer Mode to Optimize

While this method doesn’t physically delete files, it helps to visually speed up the Xiaomi Redmi Note 8T, creating a sense of a clean and fast device.

Find the Windows animation, transition animation, and animation duration. Set the 0.5x or off. The interface will become more responsive, and transitions between screens will take less time, which is especially noticeable when the memory is full.

There's also a "Do Not Store Activity" feature on this menu, which if you turn it on, the system will immediately unload background applications from RAM, which will free up RAM, but can increase battery consumption, since applications will be re-started every time they open.

• 🚀 Inserting the option “Acceleration” GPU» It can help with gaming, but it doesn’t affect memory cleanup.
• 🔋 Disabling background activity saves RAM, but sacrifices multitasking.
• ⚙️ Resetting developer settings will return all settings to factory values if something goes wrong.

Radical measures: Resetting to factory settings

If the software cleanup fails and the system continues to slow down, the final argument is a complete reset, which will bring the Redmi Note 8T back out of the box by removing all data, settings and applications.

Before starting the procedure, be sure to back up important data. Photos, contacts and documents can be saved to the Mi Cloud cloud or to your computer. Reset is irreversible, and it will be impossible to recover deleted files without a backup.

To perform the reset, go to Settings → About Phone → Settings Reset → Erase all data. The process will take 10-15 minutes. Once turned on, the phone will require you to enter a password from your Mi Account if the Find Device feature was active.

💡

A complete reset is the only way to ensure that you remove system debris and experience errors, returning the original performance to the smartphone.

⚠️ Warning: Before reset, make sure the battery is at least 50% charged.Stop flashing because of battery discharge can "brick" the device.

Prevention and Support for Productivity

To avoid future memory problems, it is important to develop a habit of regular maintenance: Don't wait until the storage is 99% full — start cleaning when less than 15-20% of the space is available, which is critical for flash memory, which slows down when overflowing.

Use cloud services to store photos and videos. Set up automatic uploading in Google Photos or Yandex.Disk and then delete local copies is the best way to keep memory free.

Remove unused apps regularly, and if you haven't opened a game or program in a month, you probably don't need it anymore, and MIUI 12 and above has a feature that tells you which apps you haven't used in a long time.
