How to Free Your Memory at Xiaomi Redmi 4X: The Complete Guide

Xiaomi Redmi 4X, despite its age, remains a popular device due to its excellent autonomy and reliability. However, owners often face the problem of lack of internal storage, which leads to slowdown and inability to install new applications. Android OS over time acquires temporary files, remnants of remote programs and a cache of messengers that can take up gigabytes of space.

Solving the problem requires a comprehensive approach, since simply removing photos does not always yield the desired result. In this article, we will look at the deep cleaning methods available to owners of devices based on the MIUI shell. You will learn how to safely remove system debris, transfer data to an external drive and optimize the operation of the built-in analyzer.

Analysis of the storage occupancy of built-in tools

Before we start taking drastic measures, we need to pinpoint exactly what is taking up space.Redmi 4X owners have access to a powerful built-in tool called Cleanup, which analyzes file structure.Running a scan can reveal not only obvious large files, but also a hidden app cache that is often ignored when manually sorting.

To start the analysis, go to the Settings → Memory menu or use the standard Security app. The system will automatically count the amount of images, videos, documents and application installation files (APKs). It is important to pay attention to the Other category, as this is where error logs and temporary update files are often hidden.

The standard analyzer will also offer to remove duplicate photos and similar images, which is especially true for users taking many pictures. Using built-in sorting algorithms allows you to quickly find large files that you may have forgotten about, such as old tape recorders or downloaded movies.

⚠️ Note: When using Deep Cleanup, carefully check the file list before deleting so you don’t accidentally erase important work documents or personal correspondence.

After initial analysis, it is recommended to immediately delete the found APK installation files if the programs are already installed. These files often remain in the download folder after updating the applications and no longer carry any functional load, occupying precious megabytes.

Cleaning the cache of applications and messengers

The most voluminous memory consumers on Xiaomi Redmi 4X are usually social networks and instant messengers such as Telegram, WhatsApp and Viber. These applications store all received media files in internal memory by default. To free up space, you need to go to the settings of each application separately through the Settings menu → Apps → All applications.

Select a heavy app and click the Clear button, and it's important to distinguish between Clear Cache and Clear Everything. The first one is safe and only deletes temporary files, speeding up the program. The second button will reset the app to factory settings, removing your correspondence and authorization, so you should use it with extreme caution.

• 📱 Telegram: In chat settings, find the item “Memory Use” and clear the cache, pre-setting automatic deletion of old media files.
• 💬 WhatsApp: Go to Data and Storage» → «Storage management to remove large video files from specific dialogs.
• 📸 Instagram: Often accumulates gigabytes of cache of storis and tape viewed, the cleaning of which is normally through the Android menu.

Chrome or MIUI Browser deserve special attention. Web cache can grow to hundreds of megabytes. You can clean it in the History section or through the general browser settings. Regularly cleaning the cache of browsers and social networks is the fastest way to return several gigabytes of free space without losing personal data.

Transferring data to an SD memory card

Model Redmi 4X It has a hybrid slot that supports microSD cards up to 128 GB or more, and transferring media files to an external drive is the most efficient way to offload internal memory. MIUI Allows you to automatically save new photos and videos immediately SD-map.

To change the default save path, open the Camera app, click on the menu (three bars) and select settings. SD-And you can activate it, and you can have the same settings in the recorder and some file managers, and that will prevent the internal storage from filling up quickly in the future.

To transfer existing files, use the built-in Explorer. Go to DCIM, MIUI, Download, and Pictures folders. Select the files you want, click Move, and select the root or created folder on the external map. After transfer, be sure to check if the files are opening from the new location before deleting the originals.

⚠️ Note: It is not recommended to transfer the applications themselves to the memory card through the Android settings, as this can lead to their unstable operation and data loss when retrieving the card.

Using a high-quality Class 10 or UHS-I memory card is critical for the Redmi 4X. Slow cards can cause lags when shooting videos or viewing heavy files, creating the illusion of a lack of performance of the smartphone itself.

💡

Use a file manager with access to the root file system to see hidden folders taking up space, but do not delete files whose purpose you do not know.

Removal of system debris and residual files

When applications are removed, the system often has tails — empty folders and configuration files — that can be found using standard MIUI Explorer. Turn on hidden files in Explorer settings and carefully review the root directory. Remote program names can be safely deleted.

A special place is occupied by the folder MIUI/debug_log, If you're not a developer or a tester, you don't need these files, they can be as large as a few gigabytes, and the cleanup of this directory is routine and doesn't affect the stability of Xiaomi Redmi. 4X.

It's also worth checking the Bluetooth folder, which stores all the blue tooth files, often with forgotten images or videos shared by acquaintances many years ago, and regularly auditing these hidden repositories helps keep the file system in order.

• 🗑️ Thumbnails: A hidden folder with gallery miniatures that can grow to huge sizes, and cleaning it will speed up the gallery.
• 📂 Remains of games: After removing heavy games, cash folders often remain in the game. Android/obb or Android/data game-studio.
• 📄 Temporary files: Files with the.tmp or.log extension at the root of the system can be deleted without fear.

For a deeper cleaning, you can use the Advanced Cleanup mode in a standard security application, which scans the system for irrelevant installation packages and advertising files left behind by some free applications.

Optimization of MIUI and disabling unnecessary

MIUI is rich in features, but some of them consume resources and space. Disabling unnecessary services and animations will not only free up memory, but also speed up the interface. First of all, you should disable automatic updates of applications over the mobile network, leaving this feature only for Wi-Fi, so as not to download temporarily heavy update packages.

In the section "Extended settings» → «For developers, you can find options that affect the storage of data, such as a limit on background processes, setting a limit on the number of background processes will help the system more aggressively unload from memory long-running applications, freeing up RAM (RAM), This also indirectly affects the storage speed.

Remove or disable pre-installed apps (bloatware) that you do not use. On Redmi 4X, these can be games, travel services or alternative browsers. Removal of them sometimes requires obtaining root rights or using ADB commands from your computer, as standard deletion can be blocked.

⚠️ Note: When disabling system components through ADB or the developer settings, be extremely careful: disable critical services from Google or MIUI It can cause the phone to be inoperable.

Using lightweight versions of apps (Lite) is also an effective strategy: Facebook Lite, Messenger Lite or Skype Lite versions take up significantly less space and consume less resources, which is ideal for a Redmi 4X configuration.

Radical measures: Resetting to factory settings

If none of the above methods helped to free up enough space, there may have been a critical file system error in the system, in which case the most effective solution is a full factory reset, which will return the smartphone to a “store-like” state.

Before you reset, make sure to back up all your important data, you can use the built-in Mi Cloud or save it to your computer, and once you reset, all contacts, photos, messages and installed apps will be permanently deleted.

To perform the reset, go to Settings → Advanced Settings → Restore and Reset. Select Settings Reset and confirm the action. The process will take a few minutes, after which the phone will restart and require initial setup, guaranteed to remove all software debris and viruses.

After reset, take your time to install all the applications at once, install them one by one, observing the amount of free memory, which will help identify the application that can cause abnormal space consumption.

💡

A complete reset is a last resort that solves 99% of memory problems, but requires a mandatory data backup.
