How to Clean Memory on Xiaomi Redmi Note 6 Pro: The Complete Guide

Owners of the popular Xiaomi Redmi Note 6 Pro smartphone often face a situation where built-in storage is overflowing, which leads to a slowdown in the system and the inability to install new applications. The accumulation of temporary files, social media cache and forgotten downloads is a natural process of operating an Android device, but in the shell of MIUI there are powerful tools to control the occupied space.

In this article, we'll look at all the effective ways to optimize disk space, from standard system utilities to manually removing hidden folders. You'll learn which files can be deleted without risking system stability and which are best left intact. Maximum efficiency is achieved with a comprehensive approach: a combination of automatic cleaning and manual sorting of media content. Let's start freeing up space on your gadget.

Use of the built-in Security application

The first and most secure tool Xiaomi offers is the Security app, which is located in the standard Tools folder or desktop and has a green shield icon, and inside this module hides the Cleanup function, which automatically scans the device for junk files, residual data from remote programs and temporary caches.

Once the scan is running, the system will suggest removing the objects found. However, it is recommended that experienced users not agree with everything at once, but look carefully at the categories. Often, the cache section hides data that applications will re-download, consuming traffic. A more sensible step is to selectively clean or use advanced settings inside this menu.

💡

When using standard cleaning, go to the Security settings and enable the Clean Cache in the Background option to automatically maintain the system.

It’s important to understand that the built-in analyzer doesn’t always find the heaviest files scattered across download or messenger directories.It focuses on system debris, so deep cleaning will require additional steps, which we’ll discuss below. However, using this tool regularly is a good habit for keeping the Redmi Note 6 Pro in good shape.

Storage analysis and removal of large files

For more detailed control, you go to the Settings menu, then select About Phone and click on Warehouse, where the system provides a visualization of what exactly the space is occupied, you will see the distribution of memory between applications, images, video, audio and system files, and by clicking on any category, you can access a list of files sorted by size.

And the other section, which is often bloated to incomprehensible sizes, can be archives, APK installation packages, forgotten documents, manual sorting allows you to find and delete video files that take up hundreds of megabytes but are no longer valuable, and it's the most efficient way to quickly free up a significant amount of memory.

Remember to check Downloads. Browsers and instant messengers often save everything you've ever opened. Deleting old documents and installers can instantly give you several gigabytes of free space. A systematic approach to analyzing storage once a month will avoid critical situations with memory shortages.

Clearing the messenger cache: Telegram and WhatsApp

Social networks and instant messengers are the main memory eaters on modern smartphones. In the Xiaomi Redmi Note 6 Pro, they can take up to 10-15 GB of space, saving thousands of photos and videos viewed. In the Telegram app, cleaning is done most correctly: go to Settings → Data and memory → Memory Use and click Clear Cache. It is also recommended to enable autodeletion of cache, for example, in 3 days or a week.

WhatsApp is more complicated because it saves media files to a shared gallery and system folders, and to clean up, you need to open chat settings, select Data Storage, and view a file list sorted by size, and you can safely remove large video files from group chats that often don't carry important information.

Be careful when cleaning the data in the App section through your phone settings. If you select the option to erase all data for the messenger, you can lose correspondence if you did not make a backup. Use only the cache cleanup function, which does not affect personal messages and contacts, this will save important data, but remove temporary debris.

Working with MIUI folder and system garbage

In the MIUI-based Android file system, there are many hidden folders created by various services, one of the most voluminous is the MIUI folder at the root of the internal drive, where the themes, wallpapers and logs of the system work, periodically, update files that have already been installed but are not automatically deleted, can be found by name containing the word updater or the extension.zip.

Another important directory is Android/data, which stores caches of games and heavy apps, and if you delete a game but the space doesn't get vacant, it's possible that the residual files are left here, but you need to delete files from this folder with extreme caution: deleting the folder with the data of the active application will lead to resetting of its settings or loss of progress in the game.

⚠️ Warning: Never delete files with the.obb extension or folders with the names of Google and Xiaomi system services unless you are 100% sure of their purpose.

For secure system files, Xiaomi’s File Manager is a good place to use it, and it has easy access to file categories and often labels unnecessary files as “Recent” or “Big Files,” making navigation easier. Regularly inspecting the root directory helps you identify forgotten folders from long-deleted programs.

Removing duplicate photos and screenshots

Over time, the Xiaomi Redmi Note 6 Pro has accumulated a huge number of screenshots, similar photos and duplicate images from different sources. MIUI can group similar images, but does not always suggest removing them. To find exact copies, you can use third-party lightweight utilities or manually go through the album Screenshots and WhatsApp Images.

Often users make a series of 5-10 identical frames to choose the best. After choosing, delete the rest immediately, without delaying. It is also worth checking the.thumbnails folder (hidden), where the thumbnails for the gallery are stored. If you deleted thousands of photos, but the space did not vacate, this particular cache of thumbnails that can be cleaned through the Security app may have inflated.

Moving old but valuable photos to Google Photos or your computer will keep your phone light. In Google Photos, you can activate the Free Space feature, which will automatically delete images already stored in the cloud.

Summary table of file types for cleaning

To organize the cleaning process, use the table below to help you quickly navigate which files can be deleted safely and which need to be verified. Properly categorizing data is key to successful optimization without losing important information.

Using a card like this as a checklist will help you avoid mistakes. Remember, cleaning the system is a balance between free space and usability. You should not delete the cache of cards if you plan to travel without the Internet, since offline cards will have to be downloaded again.

💡

Regular manual checks of Downloads and Documents folders are more effective than any automatic accelerators, since you know exactly the value of the files being deleted.
