Owners of the popular Xiaomi Redmi 4X smartphone often face a lack of free space, which inevitably leads to a slowdown and the appearance of annoying notifications. The MIUI operating system installed on this device has its own data storage features that are not always obvious to the average user. Understanding the structure of the file system is the first step to successfully freeing up gigabytes of useful space.
There are many ways to solve the problem of overcrowded storage, from simple built-in tools to the use of specialized software. In this article, we will discuss how to safely and efficiently clean internal memory without damaging important system files, learn how to find hidden “eaters” of space and prevent the recurrence of a memory shortage situation.
Analysis of storage occupancy and search for large files
Before you start deleting data, you need to determine exactly what takes up the lion’s share of the resources of your Redmi 4X. Standard Android tools often show only the big picture, hiding details in the depths of folders. For detailed analysis, it is recommended to use an integrated analyzer or third-party utilities that visualize the distribution of data.
The most effective method is to manually navigate the main directories through the file manager. Pay attention to the folders with media files, downloads and cache of instant messengers. Often users forget about downloaded video files or huge archives of documents that lie idle for months.
The MIUI system analyzer provides a handy diagram where you can see the distribution of space between applications, images, videos and other files. By clicking on a particular sector of the chart, you can access a list of files sorted by size, which allows you to instantly identify and remove the heaviest objects.
It's important to understand the difference between the space that an application has and the data that it has, and the software itself may weigh a little bit, but the cache and the content that it's loaded can grow to gigabytes, and checking those numbers regularly helps keep the system on track.
⚠️ Note: When deleting files from system folders, make sure they are not critical to operating system or other installed programs.
⚠️ Note: Deleting the.thumbnails folder may temporarily speed up the gallery, but the system will recreate the sketches that will take place again.
Using third-party analytics apps like DiskUsage or Files by Google, they provide even deeper insights into memory structure. These tools build a disk map where each file is represented by a rectangle proportional to its weight. Visualization helps you instantly find forgotten archives or error logs that take hundreds of megabytes.
Cleaning cache and removing system debris through MIUI
The built-in MIUI shell optimization tool is the first tool to be addressed by the Xiaomi Redmi 4X owner.It automatically scans the device for temporary files, residual debris and large amounts of cache. It takes only a few seconds to start this procedure and often frees up 500 MB to 2 GB of space.
To access the deep cleaning features, you need to go to the Security app and select Clean up. The system will prompt you to delete temporary files that do not affect the operation of the applications. It also offers Deep Cleanup, which analyzes photos, videos and large files, suggesting that they be deleted or moved.
Special attention should be paid to the cache of applications. Social networks and instant messengers tend to accumulate huge amounts of temporary data to quickly load content. Clearing the cache does not delete your correspondence or accounts, but resets temporary files, which often solves problems with space shortages.
The regularity of such prevention directly affects the speed of the smartphone. If you are actively using the Internet and installing new programs, the cleaning procedure is recommended to be carried out at least once a week.
⚠️ Warning: Don’t confuse cache cleaning with app data cleaning.In the second case, you’ll lose all the information inside the program, including logins and saves.
☑️ Weekly cleaning
Application management and removal of unused software
Removing unwanted apps is the most radical, but also the most effective way to free up space on Redmi 4X. Many users install games and programs just in case, forgetting about them forever. Each application takes up space for the installation file, but also creates additional data and cache.
Go to your phone's settings and select the Apps section, sort the list by the size of your memory, and you'll be surprised to find that old games or rarely used services can take up several gigabytes, and removing those programs will instantly restore free space.
Some Xiaomi system applications can be disabled if you don't need them, and this won't remove them completely, but it will stop them from working and clear some of the space they occupy, but be careful: disabling critical system components can lead to unstable interfaces.
The alternative to removing the apps altogether is to use “Lite” versions of popular apps that consume less resources, take up less memory space, and often run even faster than their heavy counterparts, and for low-end devices with limited memory, this is the optimal solution.
| Type of application | Average size | Recommendation |
|---|---|---|
| Social media | 150-500MB | Use the Lite version |
| Navigators. | 200-800MB | Store offline cards on SD |
| Games | 1-4 GB | Remove after passing |
| Streaming video | 100-300MB | Cleaning the cache regularly |
Working with multimedia: photo, video and gallery
Media files traditionally take up the most space on any smartphone, and the Xiaomi Redmi 4X is no exception.The high resolution camera results in one minute of video can weigh tens of megabytes, and thousands of photos quickly fill gigabytes.
The first thing you need to do is check the folder "Recently Deleted" in the gallery. Files you deleted often stay there for 30 days, continuing to occupy space.
Use cloud storage to archive old photos and videos. Services like Google Photos or Yandex.Disk allow you to automatically download your library and then delete local copies, which creates the illusion of infinite memory on the device.
Also worth paying attention to the folders of messengers WhatsApp and Telegram, by default they save all received images and videos to the gallery of the phone, setting up automatic cleaning of media files in the messenger applications themselves helps to avoid clogging memory with junk pictures from chats.
Photo compression is another option to save, albeit with loss of quality. There are algorithms that reduce the weight of a file without visible loss of detail to the human eye. For storing archives of family videos, this can be an acceptable tradeoff.
Use of memory card and cloud services
The Redmi 4X supports microSD card installation, which is a lifesaver for users with a small amount of internal storage, and the right setup of external memory allows you to transfer most user data to it, freeing up the system partition.
Once the memory card is installed, the system will suggest using it as a portable storage device or as part of internal memory, and Portable storage is more secure, as it makes it easy to transfer the card to another computer, but requires manual file transfer.
Set up the camera and messengers to save new files immediately on the SD-This will prevent the internal memory from overflowing in the future. In the camera settings, select "Save on" SD-map", and in the settings of messengers specify the path for downloads.
Cloud services are a great addition to a physical memory card, and they keep data safe in the event of loss or failure of a smartphone. SD-Maps for current projects and clouds for archives – the gold standard for data organization.
Remember that applications running from a memory card can run faster than internal memory, so it’s best to leave the operating system and heavy games on the built-in drive, if space permits.
Resetting settings as an extreme cleanup measure
If none of the above methods have helped to free up enough space, it may be that the problem lies in deep system errors or accumulated debris that is not removed by standard means, in which case the only effective solution is a complete reset to factory settings.
Hard Reset completely cleans the device’s internal memory, returning it to the “out of the box” state, which removes all applications, settings, accounts and files of the user, so pre-backing up critical data is a must.
To perform the reset, go to the "Settings" menu» → «Advanced settings» → «Reset and Reset. Select Reset and confirm the action. The phone will restart and begin the cleaning process, which can take several minutes.
Once the reset is complete, you’ll get a completely clean system with the maximum amount of free memory, which often not only solves the problem of the location, but also significantly speeds up the old smartphone, eliminating software conflicts.
⚠️ Note: Before resetting, be sure to remove SIM-card and memory card, so you don't accidentally format them, and also make sure that the battery is at least 50%.
