How to clean the memory of Xiaomi Redmi Note 8 Pro: the full guide

The 2019 Xiaomi Redmi Note 8 Pro is still a popular device thanks to its powerful MediaTek Helio G90T processor and high-quality camera. However, like any MIUI shell gadget, it eventually starts to accumulate system debris, temporary application files and duplicate photos. When the free space in the Internal Memory section comes to an end, the device slows down, applications fly out, and the system can work unstablely.

Memory cleaning is not just about removing redundant images, but about a comprehensive maintenance process for the Android operating system. It is important for owners of the Redmi Note 8 Pro to understand the difference between app cache, user data and system files. Incorrectly removing critical components can lead to interface failures or loss of personal data, so the approach must be methodical and conscious.

In this guide, we’ll look at all the ways you can free up space, from built-in MIUI tools to manually removing hidden folders. You’ll learn how to safely remove remnants of remote applications, transfer media to the cloud, and use special cleaning modes. Proper storage management will prolong your smartphone’s life and return it to its previous speed.

Analysis of storage occupancy through MIUI settings

The first step is always diagnostics. You don't blindly delete files without understanding what it takes to make gigabytes. The MIUI shell provides detailed statistics that show the distribution of data by category. To access this information, you go to the Settings menu, then select About phone and click on the Storage bar, and here the system visualizes memory occupancy, breaking it down into apps, images, videos, music, and so on.

Users are often surprised to find that the Other category occupies a significant portion of the disk. This section includes messenger archives, streaming services cache and temporary update files. Redmi Note 8 Pro with its 64 or 128 GB of memory can quickly fill up if you regularly watch high-resolution videos or install heavy games. Understanding the folder structure will help avoid deleting system files necessary for Android.

Note the size of the Apps section. Social media and instant messengers tend to grow to several gigabytes, saving every image and voice message viewed. Unlike simply removing an application, standard uninstallation often leaves "tails" in the form of configuration files. It is recommended to periodically check the list of the heaviest programs and assess the need for their presence in the phone.

In this case, a simple reboot of the device, after which the statistics will be updated, can help. If the numbers do not coincide with reality (for example, the sum of categories is less than occupied space), perhaps errors have appeared in the file system that require more in-depth analysis through a computer or special utilities.

Use of the built-in "Security" application

Each Xiaomi smartphone has a Security system app preinstalled, which is the primary tool for quick cleaning. When you run it, you'll see a big green button with an optimization percentage. Pressing it starts scanning the system for temporary files, uninstall residues and ad debris. For the Redmi Note 8 Pro, this is the safest way to start service, since MIUI algorithms know which files can be deleted without risk to the system.

But standard cleaning is often superficial. For deeper analysis, scroll down and select Cleanup. Here, the system will suggest removing files larger than 100 MB, duplicate photos and rarely used apps. The duplicate search feature is especially useful, since the Redmi Note 8 Pro's 64 MP camera creates heavy shots and its repetitions can steal tens of gigabytes.

⚠️ Note: When using Deep Clean, look carefully at file previews. The system may suggest removing downloaded files from WhatsApp or saved documents you still need.

There's also an Application Management section in the Security app, where you can see how much space each program's cache takes up. Unlike cleaning up the data completely, cleaning the cache is safe and doesn't require re-authorization in services. Regular use of this tool helps keep the system on track and prevents the /data partition from filling critically.

It’s worth noting that the security app also manages autoboot. Disabling unnecessary processes not only frees up RAM, but also reduces the load on the processor, which indirectly affects the speed of working with the file system. For owners of the Redmi Note 8 Pro, who are actively using a smartphone for work, this is an important aspect of optimization.

Clearing the cache and data messengers

Memory consumption leaders are traditionally messengers: WhatsApp, Telegram, Viber. They save all sent and received media files to internal memory by default. In Redmi Note 8 Pro, the Android/media folder or WhatsApp root folder can grow to incredible sizes. Cleanup should be done through the settings of the application itself, not through the file manager, so as not to disrupt the structure of the message database.

Telegram, for example, has a built-in automatic cache cleanup feature. Going to Settings → Data and Memory → Memory Use, you can set a cache storage time limit (e.g., 3 days or 1 week) This is a critical setting that will prevent the accumulation of gigabytes of temporary files. Once the limit is set, the application will delete old media, freeing up space for new data.

WhatsApp has a slightly more complicated procedure, as automatic cleaning is less flexible. It is recommended to use a built-in storage management tool: Settings → Data and Storage → Storage Management. Here you can sort chats by size and remove large attachments. It often turns out that old group chats take up 5-10 GB of space due to the endless flow of pictures and videos.

Remember that cleaning the application data (not to be confused with cache) will lead to complete deletion of correspondence and the need to re-enter your account. Use this feature only in extreme cases when the application is not working correctly or takes up an abnormally large amount of space due to database errors. For the Xiaomi Redmi Note 8 Pro with its memory capacity, regular cleaning of the messenger media library is the key to a free system.

Working with the file system and the Download folder

Download folder is a “black hole” of memory of any Android smartphone. Browsers, email clients and instant messengers by default save all downloaded files there: installation APK-file, PDF-Over time, hundreds of files are stored there that the user has long forgotten about, and for manual cleaning, you need to open the File Manager application and go to the appropriate directory.

Special attention should be paid to files with the.apk extension. Once the application is installed, the installation file is no longer needed, but often remains in the download folder. Deleting older versions of APK can free up from 500 MB to several gigabytes. Also check the DCIM/.thumbnails folder. It stores thumbnails of photos and videos. On the Redmi Note 8 Pro, with its highly detailed screen and camera, this folder can weigh several gigabytes.

For advanced users, it is recommended to install a file manager with disk space analysis, such as Files by Google or Total Commander, which visualizes a file tree, allowing you to find the "heavyweights" hidden in the depths of the system directories. file-deletion Android/data or Android/obb This can lead to incorrect operation of games and applications.

💡

Use the Size Sort feature in Explorer to instantly see the largest files on your device, regardless of their type and location, and quickly decide to delete them.

Regularly auditing your Bluetooth folder also helps. If you've ever taken files over Bluetooth, they're stored at the root of internal memory. Old videos or presentations from years ago may still take up space. A systematic approach to the file system makes chaos order.

Removing duplicates and optimizing the gallery

Xiaomi Redmi Note 8 Pro is capable of taking high-resolution images, each of which takes from 5 to 15 MB. When you use the gallery quickly fills up. Often users take a series of the same frames to choose the best, forgetting to delete the unsuccessful. In addition, when sending photos through messengers or cloud services, copies of them with changed names or in different resolutions can be created.

You can use MIUI built-in tools to find and remove duplicates (in the Gallery app -> Albums -> Similar photos) or third-party apps. AI algorithms in MIUI do a good job of grouping similar images. Deleting serial shots and screenshots that are no longer relevant is a quick way to bring back a few gigabytes of freedom.

An important aspect is the use of cloud services. Google Photos or Mi Cloud allows you to store originals in the cloud, leaving only compressed copies on the device or even deleting local files after synchronization. Google Photos’ “Free space” function automatically deletes from the phone those pictures that are already securely stored in the cloud.

Don't ignore the Recycle Bin folder in the gallery. Deleted photos often stay there for 30 days, continuing to take up space. Cleaning the cart is the final step, after which space is really vacated. On the Redmi Note 8 Pro, this is especially true for high-resolution video.

Radical methods: data resetting and transfer

If the software methods don’t help and the memory fills up on its own, it may be that the file system has accumulated errors or fragmentation has reached a critical level, in which case the most effective solution is a full reset to factory settings (Hard Reset), which will delete all user data, applications and settings, returning the phone to the “out of the box” state.

⚠️ Warning: Before performing a reset, be sure to back up your data to your PC or cloud.The process 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. Once you reboot, you’ll get a clean system. This often solves the problems with mysterious memory loss caused by software glitches of MIUI. For the Xiaomi Redmi Note 8 Pro, it’s also a great way to shake up the system after long use.

Another option for expanding the space is to use a microSD card (if the model supports it) or OTG-Although modern versions of Android limit the installation of applications on the SD-You can transfer photos, videos and documents to the map, freeing up internal memory. In the Redmi Note 8 Pro, the slot is hybrid, so you have to choose between the second one. SIM-memory-card.

💡

Factory Reset is the most effective way to combat system debris and memory-consuming software errors, and do it every 1-2 years to maintain maximum performance.

Remember, after a reset, don't install all the applications at once. Install them gradually, watching the system behavior. This will help identify a parasite application that may have caused memory problems before. Proper management of installed software is the best prevention of space shortage.
