How to Clean Memory in Xiaomi Redmi 6 Phone

Xiaomi Redmi 6, released in 2018, is still a popular device due to its price-performance ratio. However, over time, owners face a lack of built-in storage, which leads to slowdowns and inability to install new applications.

In this article, we will take a look at all available methods of freeing up space, from regular MIUI tools to advanced system file management techniques, and learn how to safely remove accumulated digital debris and optimize space without losing important data.

Before the action begins, basic diagnostics should be done to understand what exactly occupies the lion’s share of gigabytes, which will avoid removing the necessary documents and focus on the real resource eater.

The built-in MIUI storage analyzer provides detailed statistics by file category. To get to the management menu, go to Settings → Memory and wait for the system scan to finish.

Here you'll see a color diagram where each sector is responsible for a specific type of data: apps, images, videos, documents and system files. Memory analysis helps identify hidden backups or forgotten downloads that may take up gigabytes.

The first step to freeing up space is to delete temporary files that accumulate as the operating system and installed programs run, often referred to as “cache,” and their secure deletion does not affect the functionality of the software.

Xiaomi smartphones use the built-in Security app for this purpose. Open it and select the Cleanup tool. The system will automatically find temporary files, remnants of deleted programs and advertising debris.

However, standard cleaning doesn’t always remove the cache of heavy apps like browsers or social media. For deep cleaning, go to Settings → Apps → All apps, select the program you want, and click Memory.

• 🗑️ Click the “Clear” button in the cache section to delete temporary data without losing logins.
• 📂 Check the Downloads folder in the file manager, there are often installations. APK-file.
• 🔄 Use the Deep Clean feature in the Security app to find duplicates.

⚠️ Warning: Don't confuse the Clear button (for cache) with the Erase Data button. The second action will completely reset the app to the factory settings by removing your correspondence and authorizations.

WhatsApp and Telegram are among the top memory consumers on Redmi 6, and these apps store every photo and video you receive in the gallery, even if you’ve already viewed it and forgotten it.

Telegram allows you to set up automatic deletion of media files. Open Settings → Data and memory → Memory use and set a cache storage time limit, for example, 3 days or 1 week.

For WhatsApp, the procedure is a little different. Inside the app, go to Settings → Data and Storage → Storage Management. Here you will see a list of chats sorted by space you occupy, and you can selectively remove heavy attachments.

If you are missing 16 or 32 GB, the most effective solution is to use a microSD card. Redmi 6 supports the installation of cards up to 256 GB, which radically solves the problem of space shortage.

Once the card is installed, the system will suggest using it as portable storage or internal memory, and for photos and music, it is better to choose the first option to have access to files on other devices.

It is important to properly configure the camera and voice recorder so that they save files to an external drive by default, which will prevent the system partition from filling in in the future.

Removing unused apps is an obvious but often overlooked step, with many users storing games they haven't played in months or duplicated utilities.

Go to Settings → Applications → All apps and sort the list by size. You will be surprised to find that one forgotten game can take up more space than hundreds of documents.

Pay special attention to the pre-installed software from Google and Xiaomi. Although system applications are difficult to remove, they can be “disabled”, which hides them from the interface and prevents the update, freeing up some space.

• 🎮 Remove the heavy ones 3D-Games you haven’t played in over a month.
• 🛒 Check the availability of marketplace applications (AliExpress, Ozon) if you do not use them.
• 📺 Disable unnecessary Google Play services Movies, Music, if you do not use their subscriptions.

⚠️ Be careful when removing system components called "System", "Framework" or "Services" that may cause Redmi 6 to run unstable or cyclically restart.

Modern cloud services allow you to store gigabytes of photos and documents on the Internet, leaving only thumbnails on your phone, which is ideal for devices with a small amount of internal memory.

Google Photos is the default service on all Android smartphones. Enable the “Save space” function in the app settings to automatically delete photos from the device that are already uploaded to the cloud.

Alternatively, Yandex.Disk or Mi Cloud can be used. Setup automatic synchronization of the Camera folder will allow you to safely clean the gallery, knowing that the pictures are safe.

💡

Use Incognito mode in your browser or Read mode in news apps so that the cache of pages is not stored in the device’s memory after each session.

There is a category of files called Residual Files, which remain after the application is deleted and are empty folders or error logs that the system no longer needs.

The best tools for finding them are specialized utilities, such as Files by Google or SD Maid, which scan the file system for “orphan” files that are not associated with any installed application.

Regularly checking for such files helps keep the file system clean and prevents data fragmentation, which is especially important for budget drives installed in Redmi 6.

After all the cleaning procedures, it is recommended to restart the device, which will allow the system to recalculate the file indexes and correctly display the freed up space.

💡

Regularly cleaning the cache and transferring media files to a memory card or cloud is the only way to comfortably use Redmi 6 in 2026 and beyond.
