How to Free Up Space on Xiaomi Redmi: A Complete Memory Cleanup Guide

Modern Xiaomi Redmi smartphones are equipped with huge screens and powerful cameras that create high-resolution files that quickly fill internal storage. When the system notification “Memory is full” begins to pop up with frightening regularity, the device turns from a useful assistant to a source of constant irritation. Users notice that the smartphone begins to slow down, applications fly out, and new photos can not be taken without removing old ones.

Making matters worse, the MIUI operating system, or its new version of HyperOS, itself takes up a significant amount of disk space for system processes and cache, and in this guide, we will detail how to safely and efficiently free up gigabytes of valuable space without deleting important documents and contacts.

You’ll learn about hidden messenger cache folders, which often take up 40% of your memory, and the nuances of Mi Cloud. Understanding the file structure will allow you to turn chaos into order and return your Redmi to its previous speed without having to buy a new model with a large amount of memory.

Diagnostics: analysis of storage occupancy

Before you start taking drastic measures like deleting apps or resetting settings, you need to understand exactly what your device’s memory is clogged. Xiaomi’s standard diagnostics tools provide a fairly detailed visualization, but many users ignore this step, relying on or deleting files at random. Proper diagnosis allows you to identify “eaters” of space, which you may not even know existed.

To start, you should use the built-in Security tool that is pre-installed on every Xiaomi device. Go to the Settings → Storage menu or launch the Security → Cleanup app. The system will analyze the files and categorize them into apps, images, videos, documents, etc. Often it turns out that the lion’s share of memory is occupied not by your personal photos, but by the social media cache and junk files after updates.

Note the "Other" or "System Files" section, if this section is bloated to unimaginable sizes, it may indicate an accumulation of error logs or residual files from remote programs. In some cases, Android incorrectly displays the size of the system partition, but most often there are really redundant data that can be deleted manually through the file manager.

⚠️ Note: Do not delete files from system folders unless you are 100% sure of their purpose. Deleting critical libraries can lead to a cyclical restart of the device or loss of functionality of individual modules.

Cleaning of cache and garbage with standard MIUI tools

The MIUI built-in optimizer is the first tool to look at, and it can find temporary files, deleted application residues, and advertising debris, but it's important to understand that automatic cleaning is often superficial and leaves a large portion of the data intact to keep the next application running fast.

For a deeper cleaning, you need to go to the settings of a particular application. For example, in YouTube or Chrome, the cache can take several gigabytes. Go to Settings → Apps → All applications, select the heavy app and click Clean (not “Erase Data” if you want to save logins). This action will safely delete temporary files, speeding up the program.

Also worth paying attention to the Download folder, which is where browsers and messengers save all open files by default, PDF-documents and installation packages APK. Regularly reviewing this folder allows you to free up space without using third-party software. If you see files with the.apk extension that you no longer need, you can safely delete them.

Remember the Deep Clean feature in the standard security application, which scans your device for large files, duplicates, and rarely used applications, and is especially useful for finding forgotten video files that can weigh 1-2 GB each, and using this feature regularly will help keep the file system in order.

Working with messengers: WhatsApp, Telegram, Viber

Messengers are the biggest enemies of free memory on modern smartphones, and they store every photo, video, and voice message they see into the device’s local memory, and over time, these data turn into giant archives that slow down Xiaomi Redmi, and cleaning up this data requires caution to keep important correspondence intact.

Telegram handles the situation most elegantly thanks to the cloud nature of the service. You can clear the cache in the app settings (Settings → Data and Memory → Memory Use → Clear Cache) and it will not affect your chats. Media files will only be re-downloaded when you re-view. In the Auto Delete setting, you can set a limit of, for example, 3 days or 1 week so that the cache does not grow.

WhatsApp is more complicated because it stores your email history locally, and you need to use a built-in storage management tool: Settings → Data and Storage → Storage Management. The app will show the chats that take up the most space and allow you to remove heavy attachments selectively. It is also recommended to disable auto-save media in the gallery so that photos from the work chats do not duplicate in the overall album.

It is important to periodically check the Android/media and Android/obb folders, where sometimes the files of remote messengers remain. If you deleted the application but did not erase its data completely, the tails can stay and take up space. Use the file manager to find folders with the names of remote programs and clean them.

Photo and Video Management: Gallery and Cloud

Multimedia files are what we often buy smartphones with good cameras for, but they eat up memory the fastest. 4K video can take up to 300MB per minute of recording. Without regular sorting, the gallery becomes a dump where you can't find the right photo, and the place ends in a matter of weeks.

The first thing you need to do is check out the album "Recently Deleted." In MIUI, deleted files are stored there for 30 days, continuing to take up space. Cleaning this album instantly returns you gigabytes. Then you should use the duplicate search feature that many file managers or third-party cleanup applications have, and duplicates often occur when you save statuses from messengers or reboot from the cloud.

The best way to store a photo archive is to use cloud services or an external storage device. Google Photos offers a "Free Space" feature that removes photos already stored in the cloud from the device. Similarly, Mi Cloud works, synchronizing the gallery and allowing originals to be stored on the server, leaving only thumbnails on the phone.

💡

Use Compression mode in your camera settings for everyday shooting. The difference in quality on your smartphone screen is almost imperceptible, and the file size decreases by 2-3 times.

Don't forget screenshots and screenshots. We often take screenshots of important information, but we forget about them after 5 minutes. Make a rule: once a week, browse the Screenshots folder and delete the extra one. It takes 2 minutes, but over time it will save tens of gigabytes.

Using Mi Cloud and Google Photos to Unload

Cloud technology is a lifeline for smartphone owners with little internal storage. Xiaomi provides its own Mi Cloud service, which is deeply integrated into the system. It allows you to synchronize contacts, messages, notes and, most importantly, photos. When synchronized, the original photos are uploaded to the cloud, and the device can remain optimized copies of them.

To set up, go to Settings → Mi Account → Mi Cloud → Gallery and enable sync. It is important to note that there is only 5 GB of free space, so large archives will have to buy additional subscriptions or use alternatives. However, for critical documents and contacts, this volume is usually enough.

Google Photos is a more versatile solution, as it is tied to a Google account rather than a phone brand.Space Savings (formerly High Quality) allows you to store an unlimited number of photos (with some compression) for free.Regularly check your backup status to make sure your data is safe before clearing your local memory.

⚠️ Attention: Before fully clearing your local gallery, make sure that the sync in the cloud is complete. Check this through your browser on your computer by logging in. Deleting local files before downloading is complete will lead to irretrievable data loss.

💡

The combination of Mi Cloud for system data and Google Photos for media archive creates a reliable two-tiered system of protection and space saving.

Removal of applications and work with APK-file

Apps tend to grow. Social media, banking customers, and games are cached with more than the app itself. And Xiaomi phones often have pre-installed apps that you never use but take up space and resources.

Audit installed programs. Go to Settings → Apps and sort them by size. If you see a game you haven't played in six months or a food delivery app you don't use, delete it without regret. For system applications that can't be removed in the standard way, you can use the command via ADB (for advanced users) or simply disable them, which will hide them from the menu and stop the background processes.

APK installation files are worth special attention. Often we download the program from the browser, install it, and the installation file itself remains in the download folder. These files are no longer needed because the application is already installed. A search for the.apk extension in the file manager will help find and remove such heavyweights.

It's also worth checking the Android/data folder, which stores game and application data, and if you delete a game but the folder with its name (e.g. com.roblox.client) is still there, you can delete it manually, and sometimes the cleanup systems don't see these orphaned folders.
