Redmi 4X owners often experience slowdowns or unexpected freezes over time, a natural process that involves the accumulation of temporary files that the system and applications create to speed up access to data, but over time, cache memory grows to huge sizes, occupying valuable internal memory space and causing malfunctions in the MIUI operating system.
Cleaning up this temporary data is not just a way to free up space, but also an effective method of preventing software errors. Xiaomi Redmi 4X, with its compact internal memory by modern standards, is especially sensitive to storage overflows. Regular maintenance allows you to extend the comfortable life of the device without having to buy a new gadget.
In this article, we will take a look at all the cleaning methods available, from standard MIUI tools to advanced methods through the engineering menu, learn how to safely remove garbage without affecting important personal files, and understand the difference between cleaning applications and completely resetting the system cache.
The concept of cache and its impact on the work of Redmi 4X
Cache is a buffer zone in your smartphone memory where you store copies of your frequently used data. When you launch an application for the first time, the system downloads all of its resources from the disk, which takes time. When you re-start the data is taken from the cache, which happens instantly. The problem arises when the cleaning algorithms fail, and the buffer accumulates broken links or outdated versions of files.
For the Snapdragon 425 processor installed in the Redmi 4X, running with a crowded cache becomes a serious challenge. The system spends more time searching for relevant data among the garbage, which leads to visible lags, especially in heavy applications such as social networks or navigators.
Technical reference
It is important to understand that completely removing the cache will not harm the device, but it can temporarily slow down the start of programs on the first start after cleaning. This is a normal reaction of the system to the need to re-form buffer memory, the main advantage of this procedure is the stability of the operating system in the long run.
Use of the built-in "Security" application
The easiest and safest way to free up space is to use Xiaomi’s regular tool, the Security app is deeply integrated into the MIUI shell and has access to system partitions that third-party utilities often cannot penetrate without root rights. This is the first step to start servicing a smartphone.
To start the procedure, you need to find an icon on your desktop called "Security" and a green shield. Once you open, select "Clean up." The system will automatically analyze the file system and suggest removing debris, which usually takes no more than 10-15 seconds.
💡
Run a standard cleanup through the Security app at least once a week to prevent critical memory filling with temporary files.
Once you've finished scanning, you'll see a list of files that you can delete, and you should be careful: sometimes the system flags the messenger cache as junk, where important but old media files may be stored, and you're advised to review the contents before final confirmation, so you don't accidentally lose the images or documents you want.
The acceleration feature in the same app also helps close the background processes that consume RAM. While this is not a direct disk cache cleaner, the integrated approach improves the overall responsiveness of the Redmi 4X interface.
Manually cleaning the cache of individual applications
Some programs, especially social networks and browsers, tend to accumulate gigabytes of temporary data. Standard system cleaning may not affect the deep folders of such applications, so manual intervention is required. This is especially true for Telegram, VK or Chrome, which store a lot of media content.
To do the cleaning, go to the Settings menu, then select the App section and click All Apps. In the list that opens, find the program you want. Inside the app menu, you are interested in the Storage or Memory button.
- 🗑️ Click Clear Cache to delete only temporary files, saving authorization and settings.
- ⚙️ Use the option to Clean Everything or Reset only if you want to completely uninstall the application along with the data.
- 📱 For instant messengers, it is better to use the built-in cleaning functions in the application itself to selectively remove old photos.
- 🌐 In browsers, through settings, you can clear the history and cache for a selected period of time.
Focus on the gallery and file managers that create thumbnails of images. On Redmi 4X, with its limited memory, these files can take up hundreds of megabytes. Regularly checking heavy applications keeps the system on track.
☑️ Checklist for manual cleaning
After doing this, you'll notice that the amount of free memory has increased, and if an application is not working properly, sometimes a complete reset of its data helps, but this will require re-authorization, and for system stability, it is enough to clean the cache regularly.
Cleaning the system cache through Recovery Mode
If the smartphone is slow even after standard procedures, it may be necessary to clean the system cache (Dalvik/ART Cache), a deeper level of service that affects application compilation files and system temporary data.
To enter Recovery mode on Xiaomi Redmi 4X, you need to turn the device off completely. Then press the power button and volume button at the same time. Hold them until the Mi logo appears, after which the phone will go to the menu with a black background and English text.
⚠️ Attention: In the Recovery menu, the touch screen is not working. Navigation is done with volume buttons (up/down), and the choice of item is confirmed by the power button. Don't confuse menu items so you don't start a Wipe Data reset that will delete all your files.
In the menu list, use volume buttons to select Wipe Cache (or just Cache depending on the Recovery version). Press the power button to confirm. The system will alert you to action, then start the cleanup process. This can take from seconds to minutes.
Once the procedure is complete, a success message will appear on the screen: Select Reboot or Reboot to System to restart your smartphone as normal. The first run may be longer than usual, as the system will re-optimize the applications.
💡
Cleaning with Recovery Mode is the most effective way to fix system errors and lags without removing personal photos and contacts.
Comparison of cleaning methods and their effectiveness
Different cleaning methods have different levels of impact on the system, and understanding these differences will help you choose the best method depending on the current situation. Below is a table comparing the basic approaches to maintaining the Redmi 4X.
| Cleaning method | Depth of impact | Security of data | Recommended frequency |
|---|---|---|---|
| Security annex | Surface. | Absolutely safe. | Daily/weekly |
| Manual cleaning of applications | Medium | Safe (if you don’t reset the data) | As necessary |
| Recovery Mode (Wipe Cache) | Deep (systemic) | Safe for photos/contacts | Every 1-3 months |
| Reset to factory settings | Maximum | Complete deletion of all data | Only in critical failures |
As you can see from the table, for everyday use, it is enough built-in MIUI. However, if you notice that the phone has become noticeably slower after updating the firmware or installing a lot of new programs, it is Recovery mode that will be the best solution.
Do not abuse deep cleaning methods unnecessarily.Frequent cleaning of the system cache through Recovery can lead to an increase in the time of application launch in the early days, until the system collects a new optimal set of temporary files.
Memory overflow prevention on Xiaomi
To avoid the need for frequent manual cleaning, you should implement several habits of using the Redmi 4X. First, watch for free memory: if more than 85-90% of storage is filled, the system speed inevitably drops due to fragmentation.
Use cloud storage for photos and videos. Set up automatic sync with Google Photos or Mi Cloud to remove media files from your device, leaving them available online, freeing up gigabytes of space for the operating system to run.
- 📸 Enable the “Free Space” feature in Google Photos to delete already uploaded photos.
- 💬 Set up autodelete media files in the settings of messengers (for example, in Telegram you can configure autodeletion of the cache).
- 📲 Remove unused apps that are frequently updated in the background and take up space.
- 🔄 Regularly reboot your smartphone, at least once a week, to reset temporary processes.
Also worth paying attention to is the Downloads folder, which often overlooks downloaded APK installation files, documents and images from the Internet, and periodically audits the packet to find and remove unnecessary digital junk.
⚠️ Note: Do not install questionable accelerator or cleaner apps from the Play Market. They often contain ads, consume battery resources themselves, and may conflict with the built-in optimization system. MIUI.
