How to Clean Memory on Xiaomi Redmi 8 Note: The Complete Guide

Smartphones series Redmi Note has always been famous for excellent price-performance ratio, but over time, even productive devices begin to experience a lack of free space. When the internal memory of the Redmi 8 Note starts to fill up, the system starts to work slower, applications can freeze or stop running. The user is faced with intrusive notifications about the lack of space, which makes the use of the gadget extremely uncomfortable.

In this article, we will take a look at all the effective ways to free up space on your device, learn how to safely remove system debris, transfer media to an external drive and set up automatic cleaning. Proper file management will extend the life of your Xiaomi and return it to its previous speed without having to buy a new phone.

Analysis of vault occupancy

Before you start taking any drastic measures, you need to know exactly what is taking up precious gigabytes. There's a powerful monitoring tool built into the MIUI shell that visually displays the distribution of data. Go to the Settings menu, then select About Phone and click on the Warehouse bar, and here you'll see a color diagram where each file type has its own sector.

Most often, photos, videos and cache of instant messengers take the lion’s share of the volume. System files usually occupy a fixed volume that is difficult to change without flashing it, but user content and application data can grow to tens of gigabytes if you don’t control their size.

Note the Other category, which often includes residual files from remote programs, archives and temporary data, and cleaning up this section can give you a significant boost to free space, and if you see a particular application taking up an abnormal amount of space, it's worth checking its settings or reinstalling it.

💡

The MIUI storage diagram shows the real picture of the download, allowing you to point-delete the heaviest files rather than act randomly.

Don’t ignore the Apps section. Social media and instant messengers tend to accumulate correspondence history, voice messages and media viewed. Without regular cleaning, Telegram or WhatsApp alone can take up 5-10 GB of memory for your Redmi 8 Note.

Use of the built-in Security application

Xiaomi has a standard solution for system maintenance that does not require the installation of third-party software.Security app is on the home screen and has a green icon with a shield. This is the first tool to use when there are reports of a memory shortage.

Launch the app and select Cleanup. The system automatically analyzes the device for temporary files, uninstall residues and advertising debris. The scanning process takes only a few seconds, after which you will be prompted to delete the files found at a single click.

Deep Clean allows you to analyze the contents of folders in more detail, and you can find large files that you may have forgotten, or old.apk installation packages that have remained after updating applications, and be careful when removing files from this section so that you do not accidentally erase important documents.

⚠️ Attention: The memory acceleration function in the Security app closes the background processes, but does not free up storage space (RAM) inner memory (ROM).

Regular use of the built-in cleaner helps keep the system in good shape, and it is recommended to run the scan at least once a week, especially if you are actively using the Internet and installing new games or utilities.

Cleaning the cache and application data

Social media and video services are the most voracious consumers of memory, and apps like YouTube, TikTok, and VK store vast amounts of time data to quickly load content, which can eventually reach several gigabytes, taking up space that could be used for photos or documents.

To clear the cache of a particular application, go to Settings, select Apps, and find the program you want (like Instagram) in the list. Click Memory and select Clear Cache. This is a secure operation that will not affect your logins, passwords, or personal correspondence.

But there's a more radical method, called "Clean Up All Data" or "Reset," which will put the app back in state right after you install it, and all the accounts will be deleted and you'll need to log in again, and you can use this method if the app is not working properly or it takes up a critical amount of space.

Pay special attention to messengers. WhatsApp and Telegram are better equipped with built-in memory management. For example, Telegram can set up automatic cache deletion after 3 days or a week, which will save you from having to manually clean the Redmi 8 Note.

Cache deletion is a routine maintenance procedure that doesn’t delete your personal files, but can temporarily slow down the launch of apps on the first start after cleaning, as they will have to re-download the necessary resources from the network.

Working with multimedia and gallery

Photos and videos are the biggest enemy of free memory on a modern smartphone. The Redmi 8 Note camera takes quality shots that take up a lot of space. In addition, many apps create their own albums, filling the gallery with screenshots, images from messengers and banner ads.

First of all, check the Screenshots folder. Often hundreds of unwanted images are accumulated there, and it's also worth looking at the WhatsApp Images and Telegram Images folders, where every image ever received is stored, and removing this visual noise can free up gigabytes.

Remember, "Recently Deleted," when you erase photos in the MIUI gallery, they don't disappear, they move to this folder, where they're stored for another 30 days, and to make room, you open the newly deleted album and click "Delete everything."

To store photo archives, it is recommended to use cloud services such as Google Photos or Yandex.Disk. By setting up automatic synchronization with the removal of a copy from the device, you can store thousands of pictures in the cloud, leaving only selected frames on the phone.

Transfer of data to SD-map

The Redmi 8 Note features a hybrid slot that allows you to use a microSD card up to 256 GB. It’s a great solution for offloading internal memory. You can transfer photos, music, documents and even some applications to an external medium.

To transfer files manually, use the built-in Explorer. Find a folder with heavy content (for example, DCIM For a photo, select files, click "More" and select "Move." As your target directory, please specify yours. SD-This will free up the internal storage for the system to work.

💡

Use UHS-I or higher memory cards to record high-resolution video. Cheap cards can slow down your camera and app.

Some applications allow you to change the way data is saved in your settings, for example, in Yandex.Maps or 2GIS you can specify the saving of offline maps on your settings. SD-In the camera settings, it is also worth checking whether the tick to save the video only in internal memory is worth checking.

⚠️ Note: Not all applications support portability SD-Banking applications and system services must remain in internal memory for stable operation and security.

Remember, the speed of reading from a memory card is lower than that of an embedded drive. If you move too much data there, the launch of heavy applications can slow down. Use external memory primarily for media library and documents.

Removing Unused Applications and Games

Often, we install five-minute games or once-used utilities and forget about them, and these programs not only take up space, but can consume resources in the background, audit the installed applications and ruthlessly remove what you haven't used in more than a month.

V MIUI It has a convenient function to sort applications by size. Go to Settings. → Annexes → App management. Sort the list by size and analyze the top-10 And often, there are cache games or marketplaces that you can delete and re-install if you need them.

Some Xiaomi system applications can be disabled if you don’t use them (for example, Mi Video or Mi Music if you prefer third-party players).

💡

Removing one heavy cache game can free up more space than cleaning up the cache of a dozen lightweight utilities.

Removing system applications that are not removed in the standard way requires more sophisticated methods, such as using ADB (Android Debug Bridge), but it is safer for the average user to limit themselves to disabling or using alternative lighter versions of applications (Lite version).

Prevention and useful advice

To keep the memory problem on the Redmi 8 Note from returning, it is important to develop a habit of keeping an eye on the storage. Regular prevention takes less time than emergency cleaning when the phone is already barely working. Try not to fill the internal memory "to the end".

The optimal storage is no more than 80-85%. If the free space runs out, the speed of writing and reading data drops, leading to general system lags. Leave at least 3-5 GB free for normal operation of the Android operating system.

Use lighter versions of apps. For popular social networks, there are versions with the prefix Lite (for example, Facebook Lite, TikTok Lite), which take up significantly less space and consume less traffic, which is ideal for devices with limited memory.
