How to Clean the Memory of Xiaomi Redmi 8 Phone: The Complete Guide

Owners of the popular budget smartphone Xiaomi Redmi 8 often face a situation when the device starts to work slower, and notifications about the lack of free space appear with alarming regularity.It is a natural process of operation, as modern applications and multimedia files take up more gigabytes, and the basic version of the model is equipped with only 32 or 64 GB of internal memory. Ignoring the problem leads to the fact that the MIUI system begins to forcibly close the background processes, and installing updates becomes impossible.

Memory cleaning on Redmi 8 is not just about removing photos, but about taking a comprehensive approach to maintaining the Android operating system. You need to understand the difference between user data, app cache and system files so you don’t delete the extra. In this article, we’ll look at safe and effective ways to free up space that will return your gadget to its previous response speed.

Before we start taking drastic measures, it’s worth assessing the current state of storage.The system provides built-in tools for analysis, but sometimes manual intervention is required to delete really heavy files. Proper file system management will allow you to extend the comfortable life of your smartphone without having to buy a new device right now.

Analysis of storage occupancy through standard means

The first step should always be diagnosis. MIUI It has a fairly advanced built-in analyzer that allows you to visually assess what exactly occupies space. → Memory. Here you'll see a color diagram showing applications, images, videos, audio files and system data in different colors.

Often users are surprised to find that a significant part of the volume is occupied by the “Other” section, which includes messenger files, remnants of deleted programs and temporary data. Clicking on a specific category, the system will suggest moving to the list of files or starting a cleanup. Attention: do not blindly trust automatic cleaning, since the algorithm may consider important some temporary files that you have not used in a long time.

• 📊 Color indication helps you quickly identify the type of content that occupies the most space.
• 🗑️ The Cleanup feature in this menu is safe for system files, but only removes obvious debris.
• 📱 The "Applications" section will show a list of programs sorted by the amount of workload.
• 📂 Detailed viewing allows you to find forgotten downloads in the Download folder.

Using a standard analyzer is a basic level of maintenance, it doesn't require installing third-party software and ensures you don't damage system partitions, but it's often not enough to clean deep, especially if you're actively using social media.

Cleaning cache and deleting temporary files

The most massive source of junk is app cached data, created to speed up programs by saving temporary files so they don't re-download them from the Internet, and over time, this stock grows to a gigantic size, especially for browsers and video services, and can be cleaned selectively for each program through the Settings menu → Apps → All applications.

Once you have selected a heavy app (like YouTube or Chrome), click on Memory and select Clear Cache. It is important not to confuse this button with the Delete Data button, as the latter will return the app to state immediately after installation, removing your logins and settings. Regularly cleaning the cache is a safe procedure that does not affect the user's personal files.

⚠️ Cache cleaning can temporarily slow down application launches, as the system will take time to recreate temporary files when it first starts.

For faster cleaning, you can use the standard Security app (green icon with a shield), which is preinstalled on all Xiaomi smartphones. Running a scan through the Cleanup button on the home screen will find system debris. However, it is worth remembering that the built-in cleaner is sometimes too aggressive or, conversely, misses some hidden folders.

There is also the possibility of mass cleaning through an engineering menu or ADB-It can be risky for a regular Redmi 8 user, but it's better to limit yourself to standard methods that balance free space with stability of the interface, and if the cache is cleaned, then the problem lies in large files.

Working with multimedia and download folder

The majority of user memory on Redmi 8 is traditionally occupied by photos and videos. The smartphone camera takes high-quality pictures that weigh a lot, and the videos viewed in messengers are stored in cache memory. First of all, check the Internal Storage → DCIM → Camera folder. Often there are randomly shot videos or series of photos that do not carry value.

Pay special attention to the Download folder. Browsers and files received via Bluetooth or Wi-Fi Direct are saved by default there. APK installer files, documents and archives can lie there for months, taking up gigabytes, deleting these files is completely safe for the system to work.

Don't forget to check the hidden messenger folders. On WhatsApp, for example, media files are stored on the Android → media → com.whatsapp → WhatsApp → Media. You can find the Statuses and Privacy folders, which are often stuffed with unnecessary content, and clearing these directories through the file manager gives you a great result.

Removal and optimization of applications

Apps are not just the installation files themselves, but the data they generate while they work. With Xiaomi Redmi 8, with its modest features, the accumulation of background processes can significantly slow down work. Go to Settings → Apps → All applications and sort the list by size. You can find games that have not been used for six months, or navigators with downloaded offline maps.

Deleting an application completely frees up space, but if it is rarely needed, you can not delete it, but “freeze” it or limit background activity, and to do this, select Battery from the application menu and set “No restrictions” only if it is critical, otherwise it is better to leave the standard mode for saving resources.

• 🚫 Remove pre-installed apps (Bloatware) if not in use, through settings or ADB.
• 📉Lite versions of applications (for example, Facebook Lite) take up much less space.
• 🔄 Update apps regularly, as newer versions often include code optimization.
• 🧹 Use the “Duplicate Removal” function in the gallery to find identical photos.

If you use Yandex.Navigator or 2GIS, check the volume of city maps you download. Often, maps of regions you no longer plan to go are stored there, and removing them can free up 500 MB to 2 GB of space instantly.

⚠️ Note: Before removing system applications, make sure they are not required for other services to work.Removing Google Play Services components or system launcher can lead to instability MIUI.

Use of microSD memory card

One of the main advantages of the Redmi 8 is the presence of a separate slot for a memory card that does not conflict with the second one. SIM-It's the perfect solution for expanding storage, and if you buy a 64, 128, or even 256 GB card, you can transfer all the photos, videos and music to it, freeing up the internal memory to work with the system.

To save new files to the map by default, you need to change the settings. In the Camera app, click on the three menu bars and select Settings, then find Save to SD-And you can activate it. You can have similar settings in music players and some video players.

It's important to note that porting the apps themselves to a memory card in modern versions of Android is limited to developers. You can only transfer some of the data, but not the entire program executable file. So the memory card should be considered primarily as a media storage, not as an extension of the system partition.

💡

Use UHS-I speed memory cards (U1 or U3). Low-cost cards can slow down your smartphone, cause your camera to freeze while recording videos, and open files for a long time.

If you are already using a memory card, check it for errors periodically; the file system can be damaged by frequent writing and reading; periodic formatting of the card (pre-saving the data to the computer) helps keep it working and avoid reading errors.

Radical measures: Resetting to factory settings

If none of the above methods have produced the desired result, and the memory fills up on its own immediately after cleaning, it is possible that critical errors or malware have accumulated in the system. In this case, the way to completely reset to factory settings (Factory Reset), This procedure will return the smartphone to the state “out of the box”.

Before starting the procedure, be sure to back up all important data. Reset will delete absolutely everything: contacts, messages, photos, installed apps and account settings. For a backup, use the Mi Cloud or Google Drive cloud service, or manually copy files to your computer.

To perform the reset, go to Settings → About Phone → Settings Reset → Erase all data. The system will request a confirmation and password from your Mi or Google account to protect against theft. The process will take 5 to 15 minutes, after which the phone will turn on as new.

⚠️ Warning: Make sure the battery level is at least 50-60% interruption of the process by turning off the phone can cause damage to the bootloader and the need to flash through the computer.

💡

A complete reset is a last resort that solves 99% of software memory problems, but requires a mandatory data backup.

After reset, take the time to install all the applications at once. Watch the system's behavior in a "clean" form. If the memory remains stable, then the problem was a software failure. If the space disappears instantly even without the programs installed by the user, this may indicate a malfunction of the memory module itself (hardware problem).
