How to Clean Memory on Xiaomi Redmi 4X: The Complete Guide

Xiaomi Redmi 4X, released in 2017, is still popular due to its reliability and availability. However, modern applications and multimedia files are becoming increasingly demanding of disk space. Owners often face a situation where the system notifies of a critical space shortage, which leads to a slowdown in the MIUI interface and the inability to install updates.

Overflowing memory isn't just a lack of space for new photos. When the system partition fills up, the Android operating system loses the ability to create temporary files and effectively manage the cache. It causes lags, sudden closures of applications and can even lead to a cyclical reboot of the device. Therefore, regular memory cleaning is a must-have procedure to keep your gadget healthy.

In this article, we will discuss all available methods of freeing up space on Redmi 4X. We will look at the built-in system tools, manual removal of hidden files, working with multimedia and using specialized software. You will learn how to safely remove excess without affecting important system data, and extend the life of your smartphone.

Storage analysis and search for large files

Before you start taking action, you need to understand what is taking up precious gigabytes. There's a built-in analyzer in the MIUI shell that allows you to visually evaluate the distribution of data. By clicking on the Security icon on your desktop, you'll be taken to the control center where you want to select the Cleanup item. The system will scan and show you the approximate amount of garbage, but for detailed analysis, you'll better go to the settings.

For a deeper dive, go to Settings → Memory, and here you'll see a pie chart divided into categories: apps, images, videos, music, etc. Often, it turns out that the lion's share of the space is occupied by the cache of messengers like Telegram or Viber, which accumulate photos and videos they've watched for years.

• 📂 Check the download folder where installation files often accumulate APK.
• 📸 View the gallery for duplicates and failed photos.
• 💬 Study chat settings in messengers to clean up media cache.

The Download folder is worth a special attention, and many users forget that downloaded documents, game installers, and temporary browser files stay there forever, and deleting old versions of apps or archives can instantly free up several hundred megabytes.

⚠️ Note: Before deleting files from root folders, make sure they are not system files. Files with the.log or.tmp extension can usually be deleted, but it is better to double-check their purpose on the Internet.

💡

Use the Explorer app and sort files by size. Often, one forgotten 2GB movie takes up more space than hundreds of small cache files.

Use of the built-in MIUI optimizer

MIUI is famous for its aggressive yet effective optimization system. The standard Security app has a powerful cleanup module that automatically finds residual files, cache and junk, and running this feature is the fastest way to get some free space without deep interference with folder structure.

Once scanned, the system will suggest removing the objects found, but don't blindly trust the automation, the "Residual Files" list may lose important documents or save games, always review the content before confirming the cleanup, and the "Deep Clean" feature is also available on this menu, which analyzes large files and rarely used applications.

Importantly, regular use of the built-in cleaner helps keep the system’s performance stable. Xiaomi’s algorithms are able to find browser cache, remnants of deleted programs and temporary update files. This is especially true for the Redmi 4X with its limited amount of internal memory.

• 🚀 Start cleaning at least once a week for prevention.
• 🗑️ Check the “Big Files” list carefully before deleting it.
• ⚙️ Set up automatic cleaning in the Security app settings».

Remember that cleaning up the cache of apps (like YouTube or Instagram) doesn’t delete your accounts or correspondence; it only erases the temporary data that the app will re-upload if necessary. It’s a secure operation that often solves problems with software freezes.

Manual cleaning of cache and application data

Automated tools don't always see all the nuances. Some applications, especially social networks, can grow to gigabytes, storing thumbnails and stories in cache. To manage this, go to Settings → Applications → All applications. Here you can study every software installed in detail.

Select the most “heavy” application, such as VKontakte or TikTok. Inside the program menu, you will find two important buttons: “Clear cache” and “Clear data.” The first deletes temporary files, the second resets the application to the state immediately after installation, requiring re-authorization. Use the second option only if you understand the consequences.

Settings → Applications → All Applications → [Selected App] → Memory → Clean

Navigation apps like Yandex.Maps or Google Maps are particularly noteworthy. They often save offline maps that can take up a significant portion of Redmi 4X memory. If you don’t use navigation without the Internet, you can delete these files through the app’s memory management menu.

Systematic checks of installed applications will help to identify forgotten programs. Often users install a game or utility "on a single occasion", and it remains in memory for months, removing such software is the most effective way to fight for free space.

Working with multimedia and cloud storage

Photos and video are the main consumers of memory on any modern smartphone. The Redmi 4X camera takes good pictures that take up a decent amount of space. Store thousands of photos directly on the device does not make sense, especially given the presence of cloud technologies.

Google Photos offers unlimited (compressed) or limited storage for the originals. By setting up automatic sync and enabling Free Space, you will remove copies of those images from your phone that are already securely stored in the cloud, which is a safe and recommended way to do so.

If your Xiaomi has a memory card slot, be sure to use it. In the camera settings, you can specify saving new photos and videos immediately on the camera. SD-This will allow the internal memory to remain free to run the system and install heavy applications that cannot be transferred to an external medium.

⚠️ Note: When formatting a memory card as an internal storage (Adoptable Storage function), the data is encrypted, and removing such a card without first "unmounting" will lead to data loss and errors in the operation of applications.

Removing System Garbage and Hidden Folders

There are many hidden folders in the Android file system that are not visible when you normally browse the gallery. They will require a file manager with access to hidden files, such as the built-in Explorer from Xiaomi or a third-party Total Commander.

One of the biggest folders — MIUI It's at the root of the internal memory, and it often has a folder inside it. gallery_cloud (Cloud gallery thumbnails or miwallpapers, which can be safe to clean up if you're not actively using the relevant features. Android/data, where apps store their caches.

Another source of garbage is the Tencent folder, which is created when you install instant messengers from Chinese developers or games, which can store hundreds of megabytes of advertising images and temporary files, but beware: there may be important data inside, such as sent documents.

For advanced users, there is an option to clean through ADB (Android Debug Bridge), but for Redmi 4X, usually working with a file manager is enough. The main rule is not to delete files whose purpose you do not know, especially if they are in system partitions outside the User or Internal Storage folder.

• 📁 Look for folders with names of remote applications.
• 🗑️ Clean the contents of the Cache folder at the root of the storage.
• 📂 Check your Bluetooth folder for old accepted files.

Resetting to factory settings as a radical method

If none of the above methods worked, and the Redmi 4X memory is still full of “unknown files,” the last resort is a complete reset, which will return the smartphone to the “out of the box” state by removing absolutely all user data, applications and settings, which is guaranteed to free up 100% of the user’s space.

Before starting the procedure, it is critical to create a full backup. Use the built-in Mi Backup app or sync with your Google account. Save contacts, photos, documents and a list of important applications to an external medium or to the cloud. Without a backup, you risk losing all information irretrievably.

Settings → Advanced Settings → Recovery and Reset → Resetting → Erase Everything

The reset process takes 5 to 15 minutes. Once you reboot, you get a clean system. It's a great time to not install any extra apps right away, but to watch the memory fill up as it goes, and it often turns out that half of the software you've installed doesn't need at all.

💡

A complete reset is not only a way to clear memory, but also a great way to speed up an old smartphone by getting rid of the accumulated registry errors and system debris over the years.

Once reset, the system can gobble up battery and memory for a while while while file indexing and background services are being updated. Give the phone a few hours of quiet operation before making conclusions about the effectiveness of the cleanup.
