Owners of the popular budget smartphone Redmi 4X often face a lack of free space, which leads to a slowdown in the device and the inability to install new applications. This device, despite its reliability and metal body, has a limited amount of internal memory that quickly fills up with system files, garbage from messengers and remnants of remote programs. Understanding how to properly manage storage is the key to extending the life of the gadget without having to replace it.
Memory overload is not just an inconvenience, but a real threat to the stability of the MIUI operating system. When free space runs out, the phone starts thinking for a long time, applications fly out, and new photos may stop saving. In this article, we will discuss proven methods that will help you return the performance of your device and free gigabytes of usable volume.
There are many ways to optimize, from simple built-in tools to deeper cleaning methods through an engineering menu or computer. It is important to act consistently so that you do not accidentally delete important contacts or documents. Below are step-by-step instructions that are relevant to all versions of firmware installed on this model.
Analysis of vault occupancy
Before you start taking drastic measures, you need to understand what exactly occupies space in your Redmi 4X. Built-in diagnostics allows you to visualize the distribution of files into categories, which helps to identify “heavyweights” that you may not even know existed, such as old WhatsApp backups or forgotten downloads.
To start the analysis, go to Settings → Memory. The system will automatically scan the device and give a detailed report. Notice the “Other” section, which often hides the cache of system processes and application data. If this partition takes up a disproportionate amount, a more detailed check is required.
- 📊 System files – occupy a fixed amount required for Android to work.
- 📸 Multimedia – photos, videos and audio recordings that can most often be transferred.
- 📱 Applications and their data are the main source of garbage over time.
Sometimes users are surprised to find that social media apps take up several gigabytes, because all images and videos viewed are automatically saved to cache, and regular checks of statistics keep things under control and avoid critical overflows.
Use of the built-in “Cleanup” application
The easiest and safest way to free up space is to use Xiaomi’s regular tool, which already has a Security app pre-installed on all devices, and contains a powerful module to remove temporary files, which scans the system for residual debris that is not needed for the phone to work.
Launch the app and click on the Clean button, which takes only a few seconds to process, and it will find the cache files, empty folders, and the remnants of the APK installers. However, you should be careful: before the final deletion, the system will suggest you choose what to clean. Don't rush to delete everything if you are not sure about the origin of the files.
☑️ The algorithm of regular cleaning
The Deep Clean feature, available in the same menu, offers a special focus on large files, duplicate photos and rarely used apps. The Redmi 4X has a 5-inch screen, and it doesn't make sense to store dozens of movies in high resolution, rather than using cloud services or external storage.
💡
Set up automatic cleaning in the Security app so that the phone will remove the garbage itself when a certain filling threshold is reached.
Cleaning the cache and application data
The largest amount of memory in modern smartphones consume messengers and social networks. Telegram, WhatsApp, Viber and Instagram store all the media files viewed locally. Without regular cleaning, these folders can grow to several gigabytes, which is critical for Redmi 4X with its 16 or 32 GB of internal memory.
To clear a particular application, go to Settings → Apps → All apps. Select the program you want (like Telegram) and find Storage. There you will see two buttons: Clear cache and Clear everything. One deletes temporary files, the second resets the application to factory settings, removing correspondence and logins.
| Type of data | What's removed | Safe? |
|---|---|---|
| Cash. | Temporary files, thumbnails | Yes, the data will be preserved. |
| Application data | Logins, correspondence, settings | No, I need a backup. |
| APK files | Installation packages | Yeah, if the app is worth it. |
⚠️ Note: Before clearing the data (“Clean everything”), be sure to back up the correspondence in the settings of the messenger itself, otherwise you will lose the entire message history without the possibility of restoring it.
It is also worth checking the MIUI/Gallery/cloud/cache folder through the file manager. It can store thumbnails of deleted photos. In some versions of MIUI, the gallery cache is not deleted by standard means and requires manual intervention through the file manager.
Work with files in the Download and DCIM folder
Download is the black hole in any smartphone’s memory. Browsers, messengers, and email clients default to save all open documents, pictures, and installers. On Redmi 4X, this folder often grows to gigabytes of junk that just sits dead.
Open the standard Explorer and go to Downloads. Sort files by size. You may find old presentations, forgotten music tracks, or game installation files that have been installed for a long time.
Where to find hidden garbage in folders?
It's a similar situation with the DCIM folder, where you store photos and videos from the camera, and if you're shooting a lot of high-resolution videos, they'll eat up the space quickly, and you'd better set the camera up so it doesn't write in 4K, unless you really need it, or migrate the archive to your computer regularly.
Use the Recycle Bin feature in the gallery. Even after you delete the photos, they take up space until they're removed from the cart. Go to the Remove album and clean it up completely. It will instantly give you a few hundred megabytes back.
Transfer data to memory card and cloud
The Redmi 4X supports microSD cards up to 128GB, the best solution to space shortages, and you can move all media files there, freeing up internal memory for the system and applications.
Use the file manager to transfer files. Select the photos, videos or documents you want, click Move, and select yours. SD-Some versions. MIUI Allows you to immediately save photos from the camera to the memory card – check this option in the camera settings.
- ☁️ Google Photos – allows you to store an unlimited number of photos in compressed quality.
- 📂 Yandex.Disk – often gives unlimited storage for photos from mobile devices.
- 💾 Mi Cloud – Xiaomi’s cloud service for backup of contacts and notes.
⚠️ Note: Do not transfer the applications themselves to the memory card (Move to the memory card function) SD»), MicroSD card read speeds are significantly lower than internal memory speeds, which will cause software to slow down.
Cloud storage is a great option for those who don't like to carry physical media. Install a cloud service app, enable autoload photos and safely delete the originals from the device.
Removal of unused applications and widgets
Often, we install applications on a one-time basis and forget them. They hang in the background, consume RAM and take up space. On Redmi 4X with its 2 or 3 GB of RAM, every running process matters. Do an installed software audit.
Go to Settings → Apps and sort the list by size or date of last use. If you haven’t opened a game or utility for more than a month, delete it without regret. It’s also worth checking the preinstalled software from Google and Xiaomi, which you can turn off if you don’t use it.
💡
Regularly removing unused apps is the most effective way to prevent the accumulation of “digital fat” and speed up the work of an old smartphone.
Don't forget the desktop widgets. Beautiful watches, weather and news feeds are constantly updated over the Internet and use the resources of the processor. Remove unnecessary widgets from the home screen, leaving only the most necessary ones. This will not only clean up memory, but also save battery life.
