How to Free Up Space on Xiaomi Redmi Note 4X: A Complete Memory Cleanup Guide

Xiaomi Redmi Note 4X (codenamed mido) is still a popular smartphone due to the balance of price and performance. However, its main disadvantage — only 16/32/64 GB of internal memory — over time makes itself felt. Even if you do not install heavy games, the system, app cache and junk files gradually clog up storage. In this article, we will discuss all the working ways to free up space on the Redmi Note 4X, including hidden MIUI functions, storage optimization and secure removal of unnecessary data.

It's important to understand that just delete a few photos or clear the cart is not enough. On the Redmi Note 4X, the memory is occupied by system backups, duplicate files, the cache of Google Play Services and even the remnants of deleted applications. We tested each method on a real device and only selected those that give tangible results without risk to the system. If after reading you have less than 1 GB of free space, go back to the section on hidden MIUI files.

1. Diagnosis: what exactly takes up memory on the Redmi Note 4X

Before you clean it, you need to figure out which files are eating up space. On the Redmi Note 4X, the built-in storage analyzer often lies or doesn't show the full picture. Here's how to get the exact data:

1. Go to Settings → About the phone → Storage.
2. Slip on the schedule "Busy" and wait for full load (can take up to 30 seconds).
3. Scroll down to the Others section – here are hidden temporary files, system logs and debris from applications.

Typical memory allocation on the Redmi Note 4X 32GB after a year of use:

If you have an Others section that's over 3GB, that's a direct signal to action, and most of the time, you'll see:

• 📁 System Logs (.log,.tmp files)
• 🗑️ Remnants of Remote Applications (/data/app-lib)
• 🔄 Duplicates of downloaded files (especially from Telegram and messengers)
• 📊 Usage statistics MIUI (/MIUI/analytics)

2.Cache cleaning: why the standard method doesn't work

Many users limit themselves to clicking the "Clear Cache" button in the application settings. On the Redmi Note 4X, this only deletes a fraction of temporary files. To free up maximum space, you need to:

1. Clear the cache of all apps immediately through Settings → Apps → All apps → Menu (three dots) → Clear the cache of all.
2. Delete the cache of Google Play Services and Google Play Market manually (they take up to 1 GB!).
3. Reset the MIUI cache via the engineering menu: dial ##4636##, select "Usage statistics" → "Clear cache".

Warning: After the cache is completely cleared, some apps (like YouTube or Chrome) will load longer when first run.This is normal - the cache will recover after 1-2 days of use.

Clear the cache of all apps via the menu | Delete the cache of Google Play Services manually |Reset MIUI statistics via ##4636##|Reboot the phone after cleaning-->

⚠️ Warning: Do not clear the cache of com.android.systemui and com.miui.home system applications – this can cause interface failures MIUI.

3.Removal of junk files: hidden MIUI folders

Xiaomi hides from the user a lot of service folders, which eventually grow to a giant size, on the Redmi Note 4X they can be found and cleaned manually:

1. Connect your phone to your PC via USB (file transfer mode).
2. Enable the display of hidden files in Windows Explorer ("View" → "Hidden Items").
3. Go to the root folder of the phone and delete the contents of the following directories:

• 🗃️ /MIUI/analytics/ — logs of use (before) 500 MB)
• 📊 /MIUI/bugreport/ — error reports (up to) 1 GB)
• 🔄 /download/ — downloads from browsers (often duplicated)
• 📁 /DCIM/.thumbnails/ — Photo and video miniatures (up to) 300 MB)
• 🗑️ /data/log/ — System Logs (only if there is root!)

Pay special attention to /MIUI/analytics/, which contains detailed reports of your actions (which apps have run, how long you spent in each, etc.) and is collected to improve MIUI, but is completely useless to the user.

4. Transfer of applications to SD-map: circumventing restrictions MIUI

Officially. MIUI portable SD-But the map is only part of the app, but on the Redmi Note. 4X roundabout:

1. Format. SD-Card as internal memory through settings → Warehouse → SD-map → Menus. → Settings → Formatting as an internal.
2. After formatting, go to Settings → Apps, select the desired application and click "Move to" SD-map".
3. For applications where the port button is inactive, use ADB:

adb shell pm set-install-location 2

This command will force the system to install all new applications on the SD-Default card. To return the settings back, follow:

adb shell pm set-install-location 0

⚠️ Note: After formatting SD-It's not going to be used on other devices without completely erasing the data. SD It will be lower than the internal memory.

List of applications that cannot be transferred to SD-map:

• 🚫 Widgets (will stop working)
• 🚫 System applications (MIUI Home, Settings)
• 🚫 Applications with permanent notifications (Viber, WhatsApp)
• 🚫 Anticheat games (PUBG, Free Fire – Blocking your account)

5. Media Files Optimization: How to Compress Photos and Videos Without Losing Quality

Photos and video are the main memory eaters. On the Redmi Note 4X, the camera defaults to 16MP and videos to Full HD. Here's how to reduce their weight:

• 📸 In camera settings (Settings) → Camera. → Photo resolution) choose 12 MP instead of 16 MP - the difference in quality is minimal, and space is saved by 25 MP%.
• 🎥 For video, set the permission. HD (720p) Full instead HD — saving up to 50% of the space.
• 🗃️ Enable photo compression in Google Photos: Settings → Free up the space (photos will remain in the cloud, and the phone will be deleted).
• 🔍 Use Files by Google to find and remove blurred photos and duplicates.

For advanced users: If you have root, install a Magisk module called Camera2API Enabler, which will allow you to use third-party app cameras (such as GCam) with better compression optimization.

💡

If you shoot videos often, install the Video Compress app from Google Play, which compresses videos without any visible loss of quality, reducing their size by 2-3 times, for example, a minute video in Full HD (150 MB) after compression will take only 40-50 MB.

Removing System Applications: What Can Be Safely Removed

MIUI on the Redmi Note 4X is loaded with pre-installed apps that can't be removed by standard means, but with ADB or root you can get rid of most of them.

• 🎵 com.miui.player – Music (can be replaced by Spotify or VLC)
• 📺 com.miui.videoplayer - Video player (similar)
• 📖 com.miui.notes - Notes (if not used)
• 🌐 com.android.browser – Standard browser (replace with Chrome)
• 📦 com.xiaomi.scanner (no use without a printer)
• 💬 com.miui.miservice – Mi Services (responsible for advertising in the Internet) MIUI)

To delete via ADB, execute the command:

adb shell pm uninstall -k --user 0 name packet

For example, to remove the music:

adb shell pm uninstall -k --user 0 com.miui.player

⚠️ Note: Do not delete packages with the names com.android, com.qualcomm or com.miui.home, this will lead to system failure.

💡

Removing system applications does not free up space in internal memory if they have been previously updated through Google Play. First, remove the updates to Settings → Apps → Menu → Remove updates, and then delete the application itself through ADB.

7.Reset to factory settings: when it really helps

If after all the manipulations of the free space is less than 1 GB, the last chance is a hard reset. On the Redmi Note 4X, it deletes all user data, but returns the original state of the system, freeing up to 3-5 GB due to:

• 🧹 Removing all app updates
• 🗑️ Clearing cache and temporary files
• 📁 Resetting settings MIUI (including themes and widgets)
• 🔄 Deletion of statistics counters and logs

How to do the reset correctly:

1. Save all important data (photos, contacts, messages) on your PC or in the cloud.
2. Go to Settings → Additional → Recovery and Reset → Resetting.
3. Select “Clear Everything” (including internal memory).
4. After reset, do not restore the backup through Mi Account – it will return all the garbage back!

Reset takes 5-10 minutes. After the reboot, you'll have a clean system with 20 to 25 GB of free space (on the 32 GB model). The main thing is not to install all the old applications back at once. Start with the most necessary and keep an eye on the free space.
