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

Xiaomi Redmi 4X, released in 2017, was once considered a benchmark for the budget segment, offering a metal case and a standalone battery. However, time is taking its toll: modern applications are getting heavier and multimedia files are taking up more space. Owners of this device often face a critical slowdown in the MIUI interface and constant notifications of space shortages. This is not just an annoyance, but a signal that internal storage is overcrowd and the system lacks resources for background processes.

Memory cleaning on Redmi 4X is not just about removing old photos, but about a comprehensive approach to file system maintenance. The standard 16 or 32 gigabytes of memory that are available in different versions of the model are now filled in just a couple of months of active use. If you notice that the phone opens applications for a long time or spontaneously closes them, then it's time for a general cleaning. In this article, we will discuss not only standard methods, but also advanced techniques that will help to return the device to its former agility.

Before we start taking radical steps, we need to understand the structure of the disk filling. Often, the bulk of the space is not occupied by installed programs, but by their cached data and forgotten downloads from messengers. The correct organization of the cleaning process will free up gigabytes of space without losing important information. We will look at everything from simple settings to the use of specialized utilities.

Analysis of storage occupancy through MIUI settings

The first step in optimization should always be diagnostics. The MIUI operating system has built-in monitoring tools that allow you to determine exactly what is taking up space. You don't have to rely on guesswork; you better go to the menu once and see the real picture. You need to go to Settings, then select Memory or use the built-in Security app.

Inside the storage menu, the system will offer visualization of data. You will see which categories consume the most resources: it can be applications, images, videos or system files. Clicking on any of the categories, you will be taken to a detailed menu where you can delete excess files or move them to an external medium.

One of the key features is the ability to sort apps by size (busy space), which allows you to quickly find voracious programs that you haven't used in a long time. Removing such applications is the fastest way to get free space. If you need an application but it takes up too much space, try clearing its cache through the application management menu.

⚠️ Note: When cleaning application data through settings, make sure you don’t delete important information such as correspondence or saves in games, as this process resets the program to a “just installed” state».

After the initial analysis, it's recommended that you make a plan of action, so if you have photos and videos, you should move them, if you have a cache of social media, you need to clean the applications themselves, and the system analyzer is your navigator in the file world, and you shouldn't ignore it.

Use of the built-in “Cleanup” application

Every Xiaomi smartphone has a proprietary Security app that contains a powerful garbage cleaner, not just a marketing utility, but a functional scanner that can find residual files, ads and temporary data. Launch the app and click on the Cleanup button.

Cleanup allows you to work with several types of data. You can choose to clean the cache of applications, delete residual files after uninstalling programs and search for duplicates. Especially useful is the Deep Cleanup feature, which scans memory more carefully, finding forgotten downloads and large files. Regular use of this tool helps to maintain the performance of the system at the proper level.

Importantly, the built-in cleaner works in conjunction with the Mi Cloud services, offering backup before removal, which adds a layer of security: even if you accidentally delete the right photo, it can be restored, but relying on automatic cleaning alone is not worth it - sometimes algorithms miss specific debris.

💡

Use the “Accelerate” function in the Security app immediately after cleaning the memory – this will free up RAM (RAM) and speed up the start of background processes.

Keep in mind that Cleanup also offers to delete APK installation files that are left over from the software update, which are no longer needed by the system, but continue to take up precious megabytes, and their removal is completely safe and a mandatory service step for Redmi 4X.

Manual cleaning of the cache of messengers and social networks

Messengers like WhatsApp, TelegramViber are the main memory eaters on older smartphones. They store every photo, video and voice message they receive into the device's local memory. Over time, the folders with the media files of these applications can grow to several gigabytes. Cleanup must be done directly inside the settings of each messenger, not just through the Android system settings.

In Telegram, for example, you can set up automatic cache deletion. Go to Settings. → Data and memory → Memory usage and cache retention time limit (e.g. 3 days or 1 week) also has a "Clear cache" button that will securely delete temporary files without affecting your correspondence. WhatsApp takes a slightly different path: Settings → Data and storage → Storage management. Here you can select the chat rooms with the heaviest attachments and remove them selectively.

Social networks like VK and Instagram (or their analogues) also accumulate huge amounts of temporary data. These apps often don’t have a full cache clearing button in their settings, so you have to go the system way: Settings → Apps → All apps → [Select app] → Memory → Clear cache. This action won’t delete your account or saved passwords, but will reset temporary files.

Be careful with Clear Data (as opposed to Clear Cache). If you apply a full data cleanup for the messenger, you will crash out of your account and all local settings will reset. For Redmi 4X, where memory is limited, regular manual checks of messenger folders are a necessity, not an option.

File Management: Search for Duplicates and Large Objects

Over the years, you've been using your smartphone to accumulate a lot of unnecessary files in folders: old screenshots, uploaded documents, duplicate photos. It's convenient to search for them on Xiaomi using the built-in Explorer. Open it, go to the menu and select Documents or Recent. Size sorting allows you to instantly identify the files that weigh the most.

Special attention should be paid to the Download folder. Browsers and applications often save installers there, PDF-Files and images that users forget after five minutes, and deleting the contents of this folder often frees up hundreds of megabytes. DCIM/.thumbnails — If you deleted the original photos, but the space didn't vacate, maybe the problem is the bloated cache of the miniatures.

To search for duplicates, you can use third-party light utility, since the regular conductor MIUI You can't always see copies of files with different names, but even if you manually scroll through the gallery and delete similar images, you can significantly unload the internal drive. MIUI/debug_log, where error logs sometimes accumulate, taking up space.

Big file analysis is a critical step. Often users forget about downloaded movies or TV shows that can weigh 1-2 GB each. Finding these files, decide if you need them right now? If not, ruthlessly delete. On Redmi 4X, with its modest storage capacity, storing movie archives is impractical.

Transfer of data to SD-map and cloud

Model Redmi 4X It's equipped with a hybrid slot that allows you to use a microSD card. It's a lifesaver for owners of the 16GB version. You can transfer photos, videos and music to an external medium, freeing up the internal space for the system and applications. SD-map as the default recording location for camera and voice recorder.

However, not all applications support the transfer of SD-Map. Modern versions of Android and shell MIUI They limit this for security and speed, but media files are worth moving. DCIM, Music and Video in internal storage to memory card. After transfer, delete the originals from internal memory.

An alternative to a physical map is cloud storage, services like Google Photos, Yandex.Disk or Mi Cloud allow you to upload photos and videos to the Internet, freeing up space on your device. Google Photos' "Free space" feature automatically removes photos from your phone that are already uploaded to the cloud, ideal for those who do not want to carry memory cards.

When working with the cloud, it is important to have a stable Wi-Fi connection, because downloading large amounts of data can quickly exhaust mobile traffic. Set up synchronization only over Wi-Fi in the parameters of the cloud service application. This will save your money and nerves.

Application removal and system reset

If the file cleanup didn't work, you'll have to delete the apps. On Redmi 4X, every gigabyte you have installed is on your account. Go through the list of programs and delete those that haven't been used in the last six months. Games are particularly demanding to place: the cache of one modern game can take 2-3 GB. Deleting such heavyweights will give you an instant result.

As a last resort, when your phone is choking on system debris and registry errors, it helps to completely reset to factory settings. It's a radical method, but it puts the smartphone back out of the box. Before you do that, make sure to back up all contacts, photos and documents. Reset will delete absolutely all data, including accounts and passwords.

To do the reset, go to Settings → Advanced Settings → Reset and Reset → Reset. The device will reboot and start the cleaning process. Once turned on, you will have a clean system that can only install the minimum software you need, which often extends the life of older devices like the Redmi 4X for another year and a half of active use.

⚠️ Warning: Before performing a full reset, make sure that the battery is at least at least 50-60%, to prevent the phone from turning off during the (formatting) process, which could damage the bootloader.

After reset, take your time to install hundreds of applications back. Install only what you really need. This will help keep the device performing at a high level for longer. Clean installation is the best way to combat software errors and bloat system.

💡

A full factory reset is the most efficient way to clear memory and speed up the Redmi 4X, but it requires prior saving of all the important user data.
