Modern Xiaomi and Redmi smartphones offer users excellent performance and high-quality cameras, but even large amounts of internal memory tend to end at the most inopportune moment. When the device starts to run slower and notifications of space shortages appear more often, the owner faces the question of the urgent need to optimize storage. Proper cleaning allows not only to return performance, but also to extend the life of the drive, avoiding critical overflow.
The MIUI system installed on the brand’s gadgets has powerful file management tools built in, but many users simply do not know how to use them correctly. Often people delete important apps or photos, while leaving gigabytes of hidden debris that slows down the Android operating system. In this article, we will discuss proven methods of freeing up space that will help you clean up your digital home.
Don't ignore the first signs of memory shortage, as it can lead to messaging and inability to install security updates. A competent approach to data storage involves regular maintenance, rather than a one-time panic sweep before installing one heavy game. Let's look at how to start diagnosing the current state of your device.
Analysis of memory occupancy through system settings
Before you start deleting files, you need to know exactly what takes up precious gigabytes on your Redmi. The built-in storage analyzer provides detailed statistics, breaking the data into understandable categories: applications, images, video, audio and system files. Going to the Settings → Memory menu, you will see a visualization of the location distribution, where the most voluminous partitions immediately catch your eye.
Notice the Other section, which often inflates to incomprehensible sizes, which may be hiding card cache, offline music from streaming services, or forgotten downloads from the browser. MIUI tries to structure data, but sometimes user files are lost in shared folders, requiring manual intervention through the file manager.
It's important to distinguish between the amount of space that an application has and the amount of cache that it has. For example, a messenger can weigh 200 MB, but its cache of photos and chat videos can grow to 10 GB or more, and that's where the main reserve for freeing up space is often overlooked in surface cleaning.
⚠️ Note: Do not delete files from system folders with names like Android/data or MIUI, if you're not sure about 100% This can cause application settings to reset or disrupt the system.
You can use third-party tools to analyze more deeply, but in most cases, Xiaomi's standard analyzer is enough to show not only the volume, but also the date of the last access to files, which helps to identify digital junk that you haven't opened in months. Regular monitoring of these statistics will help you develop a habit of keeping your phone clean.
⚠️ Warning: If after cleaning the cache, a particular application (such as a navigator) starts running slowly at startup, it takes time to re-form temporary files for quick operation.
Use of the built-in "Security" application
Each Xiaomi smartphone has a Security system app preinstalled, which includes Cleanup functionality, which scans the device for temporary files, remnants of deleted programs and advertising debris. Running a deep cleaning through this interface is the safest and fastest way to remove several gigabytes of excess garbage without risking damaging important data.
However, it is worth noting that automatic cleaning does not always find all possible files, it acts according to a template, removing only known types of cache. To achieve maximum effect after the automatic scanner is running, it is recommended to manually check the "Big Files" section, which often suggests removing forgotten archives or old high-resolution video files.
Accelerate in the same app helps free up RAM by closing the background. While this doesn't directly affect the amount of internal memory, it can temporarily improve interface responsiveness if the phone starts to slow down due to a lack of resources.
💡
Set up an automatic cleanup in the Security app so that your phone deletes temporary files once a week, eliminating the need to do it manually.
Don't rely solely on the green clean button. The app has a detailed categorization where you can selectively remove content, for example, you can clear the cache of only one heavy application without touching the data of other programs, and this selective approach allows you to save the necessary information by getting rid of ballast.
💡
Automatic cleanup is safe, but manual checks of the “Big Files” and “Recent Deletions” sections are required for maximum results.
Cleaning messengers: Telegram, WhatsApp and Viber
The most voracious apps on any Android smartphone, including Redmi, are instant messengers. They store every photo, video and voice message received in the device’s memory. On Telegram, the best way to manage storage is to use built-in settings: go to Settings → Data and memory → Memory Use and set a cache storage limit, such as “3 days” or “1 week.”
On WhatsApp, the situation is similar, but files are often duplicated in the gallery. Go to the chat settings or the app's general settings, the Data Storage section, and look at the file list sorted by size. You'll be surprised at how much space is taken up by status and video forwarding from group chats that you haven't even opened. Deleting that data through the app's settings is secure and doesn't delete correspondence.
There's also a cleaning mechanism for Viber, but it's less flexible. It's often easier to use a file manager and find a Viber folder at the root of internal memory or on a memory card, where you can manually delete Media or Backups folders if you don't need backups or are already saved to the cloud.

However, if you decide to delete the app itself without prior backup, all local data will be lost irrevocably.Always check for a backup in Google Drive before drastic action.
Working with the photo gallery and DCIM folder
The DCIM folder is the primary repository for all photos and videos taken on camera. Over time, thousands of images accumulate there, including failed shots, interface screenshots and long 4K video recordings. You should go to the album "Recently Deleted" in the MIUI gallery and clean it up, since the files there take up space for another 30 days before automatically disappearing.
Use the "Similar Photos" or "Best Pictures" feature if available in your gallery version to find and remove duplicates. Often we do a series of 10 photos to pick one good one, and the other nine remain dead weight. It's also worth checking the Screenshots folder, which stores screenshots that are rarely needed for longer than a week.
Video files take up the lion's share of the space. If you have a MicroSD card, set the camera to save video right there. For existing videos, you can use cloud services like Google Photos with Free Space, which will remove copies of photos that are already stored in the cloud.
☑️ Cleaning the gallery
Remember the Downloads folder, which is where browser and instant messenger images often get, and they don't always show up in the main gallery feed, but they take up space. You can audit this folder once a month, removing the installation boxes. APK-files and saved images from the Internet.
Removing applications and working with cache
Many users install one-time games or food ordering apps that are rarely used. These programs don't just hang on the list, they can update in the background and consume resources. Go through the installed apps list in the settings and sort them by size. Heavy games and social networks are the first candidates for removal or portability.
If you can't remove an application (system), you can turn it off. This will hide it from the menu and stop the background processes, although it will still take up space. For custom applications, use the Clear Data function only if you're willing to reset the program to factory settings. Conventional Cache Clearing is more secure and efficient for freeing up space.
Some apps allow you to transfer some of the data to a memory card, although in modern versions of Android this feature is limited. Check the settings of each large application: maps (Google Maps, Yandex.Maps) often store offline maps of entire regions that can take several gigabytes. If you are not on a trip, you can safely delete offline maps.
| Type of data | Wherever | Can I remove it? | Risk of data loss |
|---|---|---|---|
| Cash app. | Settings → Applications | Yes, it's safe. | Low (Temporary Files Only) |
| Application data | Settings → Applications | Careful. | High (resetting settings, logins) |
| Download folder | File manager | Yes, selectively. | Medium (may be important documents) |
| System files | Root folder | No. | Critical (phone breaks) |
Also worth paying attention to widgets and live wallpapers: They don't take up much disk space, but they consume RAM and battery power, which indirectly affects overall system performance when resources are scarce. Disabling unnecessary visuals can help older Redmi models work faster.
Transferring data to cloud storage and PC
The most radical and efficient way to free up space is to move archives to an external medium or to the cloud. Google One provides a base volume for free, integrating with the system. Set up automatic upload of photos and videos, and then use the "Free space" button in the Google Photos app. This will delete local copies of already uploaded files.
Xiaomi’s own Mi Cloud is available to users of the ecosystem, synchronizing contacts, notes, voice recorders and gallery. Activation of synchronization allows you to store original photos in the cloud, leaving only optimized thumbnails on the phone that take up ten times less space.
Do not forget about the classic method - connecting the phone to the computer through USB-By flipping your photo, video, and document folders onto your PC's hard drive, you're guaranteed to free up tens of gigabytes, and it'll also create a physical backup of your data in case your smartphone is lost or broken.
⚠️ Note: Before transferring files to your computer, make sure that the mode is USB-Connection option selected "File transfer» (MTP), It's not just Charging, otherwise the computer won't see the phone's internal memory.
MicroSD cards are still relevant for Redmi's low-end models with little internal storage. While modern apps are reluctant to be mapped, storing media, music and documents is a great solution. SD-map in the appropriate application settings.

Additional methods of system optimization
There are less obvious ways to free up space, which are system logs and error reports. In the developer menu (which you need to activate by clicking seven times on the build number in the About section), you can find the option to disable logging, although on modern versions of MIUI access to this is limited. The easiest way is to clean up the data of the Google Play Services service if it starts to work incorrectly and inflate the cache.
Another method is to remove unused language packs and fonts if your version of MIUI allows you to do so through the theme or region settings. Changing the region to India or Singapore sometimes opens up additional cleaning features or changes the set of preinstalled software, but this requires caution.
Formatting the device to factory settings is a last resort. If the phone is in use for several years, there are many errors and residual files in the system that cannot be manually deleted. A full reset (Settings → About the phone → Resetting) will return the device to the state out of the box, freeing up maximum space, but will take time to reconfigure.
💡
A full factory reset is the most effective way to clean your phone, but it requires you to back up all your important data.
Regularity is key to success. Don't wait for your phone to go stake. Take 10-15 minutes to check the storage once a month, and your Xiaomi Redmi will be happy with the speed for years to come. Combine automatic tools with manual controls, and memory shortages will bypass you.
