How to Clean Xiaomi Redmi Note 8: The Complete Guide

Xiaomi Redmi Note 8, released in 2019, is still a popular device due to its balance between price and performance. However, over time, even the most powerful processor can start stumbling on simple tasks if the system is overloaded with digital garbage. Memory cleaning and optimization of the software environment is not just a way to make room for photos, but also a necessity for extending the life of the gadget.

Owners often wonder why a device that flew in the first months of use now opens apps for seconds, with the answer being accumulated cache files, residual data from remote programs, and fragmentation of internal memory. The right approach to maintaining the device will allow it to return to its former aspiration without having to buy a new model.

In this article, we will discuss all the effective ways to clean the Redmi Note 8 from unnecessary junk. We will touch on the built-in MIUI tools, the possibility of deep cleaning through the computer and even radical reset methods if the situation is critical.

Analysis of memory occupancy and search for "eaters" of the place

Before you start taking active action to delete files, you need to do a thorough review of what exactly takes up precious space. The built-in MIUI analyzer provides fairly detailed statistics, but sometimes it is worth looking deeper. System files and user content are often mixed, and mindless deletion can lead to errors.

To start with, you should use the standard “Security” app, which is pre-installed on every Xiaomi device, which automatically scans the device and sorts data into categories: apps, images, videos, documents, etc. On the Redmi Note 8 with 64 GB of memory, the system partition can take up to 15-20 GB, which is the norm for modern versions of Android.

And you look at the Downloads folder and the messenger data, and that's where gigabytes of useless information accumulate: old stickers, videos you've watched, duplicate documents, and people often forget that Telegram and WhatsApp store all the media files by default, turning the phone into an archive.

There are several clear signs that memory is overflowing and requires immediate intervention:

• 📉 The system is slow, and interfaces slow down even in simple menus.
• 📸 Refuses camera opens or gives an error when trying to take a picture.
• 🔄 Apps fly out immediately after launch or cannot be updated.
• 💬 There are constant notifications about the lack of space for new files.

⚠️ Note: Do not delete files from folders called Android, Data or Obb manually unless you are 100% sure of their purpose.

Use of built-in MIUI tools for cleaning

Xiaomi’s MIUI shell features a powerful set of utilities to maintain the system, which is a sin not to use. The standard approach allows you to safely delete temporary files without affecting important user data. This is the first step that every owner must take before more radical measures.

Run the Security app and select Clean up. The system will scan the device and suggest removing the garbage. However, click on the More Details button or go to deep cleaning to manually check the categories. Often you can find forgotten screenshots, large video files or APK installation packages that are no longer needed.

Pay special attention to the Apps section, where you can sort programs by size of space you take up. If you see an application that you don't use but it weighs a few gigabytes (as is often the case with social media), you'd better delete it or clear its cache through settings.

Here is a checklist of actions for quick optimization through standard means:

Remember, cleaning the cache doesn't delete your logins, passwords, or correspondence. It's just temporary data that speeds up applications, but grows into obscene sizes over time. Regular procedure will help keep the Redmi Note 8 in good shape.

Deep cleaning of messengers and social networks

The biggest memory eaters on a modern smartphone are messengers. Telegram, Viber, WhatsApp and VK store every file viewed in the memory of the device. Over time, folders with media files of these applications can grow to 10-20 GB, which is critical for a model with 64 GB of memory.

Unlike simple cache cleaning through Android settings, messengers have their own built-in memory management tools that work much more efficiently. They let you delete files selectively by date, type or size without losing your correspondence history. This is the key to freeing up space without losing communication data.

For example, on Telegram, you need to go to Settings → Data and Memory → Memory Use. You can clear the cache with a single click, and set up automatic deletion of old media. On WhatsApp, the path is through Settings → Data and Storage → Storage Management, where you can easily see which chats occupy the most space.

Comparison of methods of cleaning popular messengers:

⚠️ Note: When you clean messengers through the file manager (by manually removing folders), you may lose the ability to open previously downloaded files.

Removal of duplicates and large unused files

Often, the device stores files that the user does not even know exist, such as duplicate photos taken when the camera crashes, or forgotten movies in high resolution. For finding such objects, standard MIUI tools may not be enough, so you should resort to specialized tools.

Apps like Duplicate Files Fixer or Files by Google can scan internal memory and find identical files from their digital hash, which allows you to safely delete copies, leaving only the original, and it is also useful to look for files larger than 100 MB — often old game updates or downloaded maps of the navigator.

The process of manually checking the file system through the computer also gives excellent results. By connecting the Redmi Note 8 to USB in file transfer mode (MTP), you get access to the entire folder structure, and it is convenient to remove folders with the names temp, cache or remnants of applications that have been deleted long ago.

The main types of files that are worth looking for and deleting in the first place:

• 🗑️ Files with.log extension (app error logs).
• 🎞️ Video files from messenger folders (often duplicated).
• 📦.apk installation packages in the Download folder.
• 📸 Serial photos and unsuccessful shots from the gallery.

💡

Use the Sort by Size feature in the file manager to instantly see the heaviest files on the device, regardless of their type.

Cleaning through Recovery Mode and Resetting Settings

If the software cleaning fails and the phone continues to run slowly, it may be a deep system error or database fragmentation, in which case the only effective solution is a full reset to the factory settings (Hard Reset), a radical measure that will bring the phone back out of the box.

Before starting the procedure, it is critical to back up all the important data. Once reset, it will be impossible to recover information. Use the Mi Cloud, Google Drive or just copy photos and documents to your computer. Make sure that the battery is at least 50-60%.

To reset the Recovery menu on Xiaomi Redmi Note 8, turn off your phone, then press the Up and Power buttons at the same time. Hold them until the Mi logo appears, then let them go. In the menu that appears, select the language (English), then go to Wipe Data → Wipe All Data → Confirm.

Once the process is complete, the phone will restart and the initial setup will begin, which will take longer than usual, and this method allows you to completely clear the system partition of accumulated debris that cannot be removed by conventional means.

⚠️ Note: Recovery Resets ALL Data, including Contacts, SMS, Photos and installed applications. Do not miss the stage of creating a backup!

💡

Hard Reset is the only way to ensure that software errors and viruses that have been embedded in system partitions are removed.

Prevention and advice on maintaining speed

Once you've successfully cleaned the Redmi Note 8, it's important to maintain the result. Constant garbage accumulation is a natural process for smartphone use, but it can be controlled. Regular maintenance is more important than one-time vacancy promotions.

Try not to fill up your internal memory. Android requires free space for the normal operation of the write and read mechanisms. If the memory is more than 90% full, the speed of the phone drops sharply, regardless of the power of the processor.

It's also useful to reboot the device periodically, which allows you to clear the RAM from the hanging processes and update system services, and one reboot per week is enough to keep MIUI running smoothly.

Recommendations for long-term maintenance:

• 📅 Once a month, you audit the installed applications.
• 📸 Set up sync photos with the cloud and delete them from the device.
• 🚫 Disable auto-update applications via mobile network.
• 🔄 Use "light" versions of applications (Lite) for weak devices.

Compliance with these simple rules will allow your Xiaomi Redmi Note 8 to stay fast and responsive for a long time.Do not neglect digital hygiene, and the smartphone will pay you a stable job.
