Owners of the popular Redmi 4X often face a situation where the device suddenly starts to run slower, and notifications of a lack of free space appear with alarming regularity.This is a classic problem for budget smartphones with 16 or 32 gigabytes of internal storage, which is quickly filled with system updates, messengers and photos. Effective memory cleaning on Xiaomi Redmi 4X requires a comprehensive approach, since standard removal of applications often does not give the desired result.
In this article, we will not only explore obvious methods like uninstalling programs, but also cover hidden parts of the system, working with the cache of applications and analyzing the file system. You will learn to distinguish important system files from digital garbage and safely free precious megabytes. Proper maintenance of the drive will prolong the life of your gadget and return it to its former performance.
Before we start taking radical action, it's important to understand where free gigabytes go. Android accumulates a huge amount of temporary data over time that is no longer needed but takes up space. Let's look at the main areas of work to optimize disk space.
Occupancy analysis and built-in cleaning tools
The first step is always to diagnose, and you don't have to blindly delete files for good luck, and there's a built-in tool in the MIUI shell that's pretty effective at handling basic garbage, and you just have to open the Security app and select Cleanup, and the system scans the device and suggests that you delete temporary files, uninstall residues, and junk.
But the built-in scanner doesn't always see everything. For a deeper analysis, we recommend using the memory management section. Go to Settings → Memory (or Advanced Settings → Memory depending on the firmware version). Here you'll see a color diagram showing the space distribution, which will help you understand what's the lion's share: apps, media files or system data.
Often users are surprised to see the huge volume in the Other category: it can be files that the system cannot classify, or offline map data, video streaming cache and archives. Clearing the cache through the settings of a particular application is often more effective than general cleaning. For example, YouTube or Telegram can store gigabytes of videos viewed and files received for years.
⚠️ Warning: Don't use the dubious Play Market-based "200% acceleration" software that promises "acceleration" and often is a source of advertising and intrusive notifications themselves, consuming Redmi resources. 4X background.
Regular monitoring prevents critical filling, if the space is less than 10% of the total, the system starts to work unstable, and try to keep at least 2-3 gigabytes of storage available for recording and updating.
Working with garbage in messengers and social networks
The main memory eaters on modern smartphones are not system files, but messengers. WhatsApp, Viber, Telegram and VK automatically store every photo, video and voice message received. Over time, folders with media files of these applications can grow to 5-10 gigabytes, which is critical for Redmi 4X.
The most effective way to combat this is to manually clean through the app's settings. On WhatsApp, go to Settings → Data and Storage → Storage Management. Here you'll see a list of chats sorted by location, and you can selectively remove heavy attachments from group chats without losing your correspondence history.
Telegram makes things even easier with cloud storage. Go to Settings → Data and Memory → Memory Use. You need to find the Cached Files slider and click Cache Clear. You also need to install automatic cleanups like 3 days or 1 week, which ensures that the old videos you watched won’t flatter dead weight.
For social networks like VK or Facebook, the situation is more complicated, as they cache news feeds and thumbnails.The best solution for them is to periodically reinstall the application or use their lightweight versions (Lite), which consume less resources and space.
- 📱 Check the Downloads folder in the file manager regularly – installations often remain there. APK-Files that are no longer needed after installing programs.
- 🗑️ Disable auto-save media in the gallery for all messengers, so as not to duplicate files in the system memory.
- ⚙️ Use the built-in “Space Clear” feature inside the settings of each heavy app.
💡
In Telegram settings, enable the “Auto-Delete Old Messages” feature for secret chats and groups to make room automatically.
Removal of system debris and residual files
Even after you delete applications, you still have their tails in your memory, folders with settings, logs, and time data, and you'll need a file manager to get to them. The standard MIUI Explorer allows you to sort files by type, but you'll want to use advanced tools like Total Commander or FX File Explorer for deep cleaning.
Note folders with names of programs that have been deleted for a long time. Often, directories with names like com.example.game remain in the root of internal memory or in the Android/data folder. If you are sure that the game is deleted, you can easily delete this folder. However, be careful: deleting system folders can lead to malfunctions in Xiaomi.
Special attention should be paid to the MIUI folder at the root of the system, which often contains a gallery folder with cloud thumbnails and a cloud folder with temporary synchronization files. Cleaning the contents of the cloud folder (but not the folder itself) is secure and can free up hundreds of megabytes.
The way to check: /storage/emulated/0/MIUI/gallery/cloud/It's also worth checking the Android/obb folder. It stores the hard game cache files (graphs, sounds) If you deleted the game but the space didn't vacate, chances are the heavy file is left here. Find the folder with the game name and delete it.
☑️ Verification of residual files
Optimization of multimedia and photos
High-resolution photos and videos are the biggest enemy of free memory on the Redmi 4X. The camera takes great pictures, but they take up a lot of space. The first step is to move all media content to an external drive or to the cloud. Google Photos offers unlimited (albeit compressed) storage, which is ideal for archiving.
If you're not using the cloud, use a microSD card. In the camera settings, you can save new photos right to the map. For existing photos, use the file manager to move the DCIM and Pictures folders to an external medium. This will instantly free up the internal memory of the system.
Another effective method is video compression. The MP4 format that the camera uses can be converted into a more efficient H.265 codec (HEVC), which takes up half the space at the same quality. There are special converters for this, but it is easier to set the camera up immediately to shoot at 720p resolution, if 1080p is not critical for you.
⚠️ Warning: Before moving or deleting large arrays of photos, make sure to back up your computer. A file system error can result in the loss of all family archives.
Don't forget the screenshots. Screenshots are often filled with images that took one minute, and do a review of that folder and delete everything that's superfluous, and also check the Bluetooth folder, where all files received by your friends' bluetooth are dumped.
Comparison of cleaning methods: efficiency and risks
To help you choose the best maintenance strategy for your Xiaomi Redmi 4X, we have prepared a method comparison table that will help you assess the labor costs and potential benefits of each action.
| Cleaning method | Efficiency | Security | Difficulty |
|---|---|---|---|
| Integrated MIUI cleaning | Low (100-300MB) | Tall. | Minimum |
| Clearing messenger cache | High (1-5 GB) | Tall. | Low. |
| Removal of residual folders | Medium (200-800 MB) | Medium (needs attention) | Medium |
| Reset to factory settings | Maximum (frees everything) | Low (Data Loss Risk) | Tall. |
As you can see from the table, the biggest effect is a comprehensive approach or a radical reset. However, regular cleaning of messengers gives excellent results with minimal risks.
If standard methods don't work, you might want to consider installing Custom ROM. Lightweight versions of Android, like LineageOS, take up significantly less space in the system partition, leaving more space for the user, but that's the advanced user level.
Radical measures: Resetting and reflashing
When the memory is critically filled and the phone almost stops responding to commands, the final argument is a full reset to factory settings (Hard Reset), which will return the Redmi 4X to the “out of the box” state, removing absolutely all user data, applications and files.
To perform the reset, go to Settings → Advanced Settings → Restore and Reset. Select “Reset” and the system will alert you to data loss. Make sure that the battery is at least 50%, and better fully charge the device before starting the procedure.
After reset, take your time to install all the applications at once, install only the essentials and watch the memory fill up, which will help you understand which application is the main user of resources, and often one "curve" of software can eat gigabytes a day.
What if the phone doesn’t turn on after resetting?
In some cases, the problem is not the user files, but the file system error. If the space is lost on its own, you may need to format the internal drive through Recovery mode, a more complex procedure that requires a PC and Fastboot skills.
💡
A complete reset is not a panacea, but a last resort, always back up your contacts and important photos before starting the procedure, as it is almost impossible to recover deleted files after resetting.
