How to Free Up Space on Xiaomi Redmi 4X: From Cache to Reset to Factory Settings

Xiaomi Redmi 4X is still a popular budget smartphone, but its main drawback is a modest amount of internal memory (16 or 32 GB). Over time, even 32 GB is clogged with photos, apps and system debris, and the phone begins to slow down, issue notifications about the lack of space and refuse to install updates. In this article, we will analyze 7 proven ways to free memory on the Redmi 4X – from basic (cache removal) to radical (factory reset).

The main feature of this model is the lack of support for adoptable storage (conversion). SD-The cards are part of the internal memory, so the transfer of applications to the external drive is limited, but even with this limitation, you can effectively manage the free space, if you know which files are safe to delete and which are not. We will also show you how to avoid common errors that cause users to lose important data or break the system.

1. Analysis of occupied space: what exactly eats memory?

Before you clean your smartphone, you need to know which files take up the most space. On the Redmi 4X, you can do this in two ways:

• 📊 Through built-in settings → Memory: shows the distribution by category (applications, multimedia, cache, system).
• 🔍 Using third-party analyzers (e.g. Files by Google or Google) SD Maid: Details the occupied space up to individual folders.

A typical picture on the Redmi 4X with 16 GB of memory:

The key problem is that the MIUI system on the Redmi 4X reserves up to 3-4 GB for its needs, and this space cannot be vacated without root rights.

2. Cleaning the application cache and system

Cache is a temporary file that creates applications to speed up work. On Redmi 4X, the cache can take anywhere from 500 MB to 2 GB, and many programs (such as Facebook or YouTube) accumulate it aggressively.

• 🧹 For a separate application: Settings → Annexes → Select a program → Warehouse → Clear the cache.
• 🗑️ For all applications at once: Settings → Memory. → Clear the cache (button at the bottom of the screen).
• 🔧 Through Recovery mode: suitable if the system brakes and does not allow to clear the cache in the usual way (instruction below).

Important: Clearing the cache does not delete application data (logins, game saves), but it can slow down their operation until the first new start. If the cache quickly accumulates again after cleaning, check the applications for background activity in Settings → Battery → Battery use.

Make sure that important applications (messengers, banks) are not updated in the background|

Close all programs before cleaning |

Do not clear the cache of system applications (for example, MIUI System)|

After cleaning, restart the phone-->

If the Clear cache button in memory settings is inactive, it means that the system has blocked the cleanup due to a critical battery level (less than 20%).

3. Removal of unnecessary applications and their data

Redmi 4X has a lot of MIUI and Google system applications that can't be removed without root rights.

• 🚫 Disable unnecessary programs: Settings → Annexes → Choose. → Disable. That will free up the space occupied by the updates of these apps.
• 🗃️ Clear data for rarely used applications (such as Mi Video or Mi Music).
• 📱 Remove user programs you don’t use (especially games and social media).

List of safe to disable system applications on Redmi 4X:

• 🎵 Mi Music (if you use Spotify or YouTube Music)
• 📺 Mi Video (substitutes: MX Player, VLC)
• 📰 Mi Browser (better to use Chrome or Firefox)
• 📡 FM Radio (if you don't listen to the radio)

💡

Before disabling system applications, check if they are related to key features (for example, Mi Account is responsible for synchronizing data).

Root rights will be required to completely remove pre-installed apps, but on Redmi 4X it is risky: wrong actions can lead to bootloop.If you do decide, use Titanium Backup (power users only).

4. Transfer of files to SD-map and cloud storage

Redmi 4X supports microSD up to 256 GB, but with limitations:

• 📁 You can only transfer multimedia (photos, videos, music) and some application data (for example, maps in Google Maps).
• 🚫 Applications cannot be transferred in full (no adoptable storage function).
• ☁️ Alternatives: Cloud storage (Google Photos, Mi Cloud, Yandex Drive).

Instructions for transferring files to SD:

1. Put it in. SD-map (formatted as a portable storage).
2. Open Explorer (or Files by Google)
3. Select files (for example, a folder) DCIM/Camera), Click Move and select SD-map.
4. To automatically save new photos to SD: open Camera → Settings → Save Place → Memory Map.

Important: if SD-The card is formatted as internal memory (via Settings) → Warehouse → SD-map → Formatted as internal, it can't be extracted without losing data. 4X This mode is unstable and can lead to failures.

5. Cleanup of downloads, duplicates and debris

The Download folder and browser cache often contain gigabytes of unnecessary files. On Redmi 4X, you can clean them up like this:

• 📥 Downloads: Open the Explorer → Downloads. → highlight unnecessary files → Delete.
• 🌐 Browser Cache: In Chrome or Mi Browser go to Settings → History → Clear the data.
• 🔄 Duplicate photos: use Files by Google (Clean up section) → Duplicate).
• 📂 folder Android/data: contains a game cache (for example, PUBG Call of Duty can take a lot of time. 1–2 Only remove if you are not playing this game.

For deep cleaning of garbage, applications are suitable:

• 🧹 SD Maid (can find residual files after uninstallation of programs).
• 🗑️ CCleaner (clears cache, call history, SMS).
• 🔍 Files by Google (simple interface, shows "junk" by category).

💡

Do not manually delete files in Android/obb or Android/data folders unless you are sure of their purpose – this can break apps.

If you don't have any space after cleaning, check the.thumbnails folder at the root of your internal memory, and it stores thumbnails of photos and videos that can weigh up to 500MB. You can delete it without consequences, the system will restore thumbnails automatically.

6.Remove old MIUI updates and logs

System system MIUI Stores update packages in the folder /cache and /data/ota_package. These files can be used up to 1–1.5 GB and safely removed:

• 🔄 Through the Explorer: Go to Internal Memory → cache and delete all files with the.zip extension.
• 📦 Through Settings: Settings → The phone. → Updating the system → Three dots (menu) → Remove the downloaded package.

It is also useful to clear the system logs (files with the.log or.txt extension in /log and /data/log folders).

1. Install Root Explorer (if there is a root) or use ADB.
2. Execute the command: adb shell rm -rf /data/log/*

Warning: Do not delete files in /system or /vendor folders, this will cause system failure. If you are not sure, use safe methods (for example, cleaning through MIUI Optimizer).

7. factory reset (last resort)

If all the previous methods didn't work, and there's less than 500 MB of free space, you'll have to do a hard reset, which will delete all the data, so first of all:

• ☁️ Backup your Mi Cloud or Google Account.
• 📱 Keep your contacts on SIM-map or export to.vcf file.
• 📁 Transfer the photos and videos to the PC or SD-map.

Reset methods on Redmi 4X:

1. Through settings: Settings → Additional → Recovery and Reset → Resetting.
2. Using Recovery (if the phone doesn't turn on): Turn off the device. Press Volume++ Power until the Mi logo appears. Select Wipe Data (manage volume buttons, confirm - power button).

💡

After reset, don't restore the backup right away -- first check how much space is freed up. Sometimes the copy contains the same garbage that will refill the memory.

Attention: Redmi 4X Reset to factory settings does not delete files on SD-the card, but if it is formatted as an internal memory, the data on it will also be erased.
