How to Free Memory on Xiaomi Phone (Redmi/POCO) Without Deleting Files: Full Guide

The memory filled on Xiaomi is a problem that every second user faces. Even if you don’t download movies or install dozens of games, MIUI is gradually eating away at the space: app cache, temporary files, duplicate media and hidden log files take up gigabytes. But what if you don’t want to delete anything? Because photos, documents and apps are often needed “just in case.”

Fortunately, Xiaomi has a lot of hidden tools to free up memory without losing data, from built-in MIUI features to manual optimization methods, we have collected 12 proven ways to return 3 to 15 GB of free space, most of which do not require root rights or technical skills, followed by step-by-step instructions explaining why each method works and what pitfalls to consider.

1. Cleaning the application cache and system

Cash is the main memory eater on Xiaomi, which is temporary files that create applications to speed up work, accumulate over time and can take up to 5-8 GB (especially in messengers, social networks and games), but you need to clear the cache correctly, otherwise some programs will slow down or require re-authorization.

There are two types of cache in MIUI: Applications (managed manually) and System (cleaned automatically, but not always efficiently). Start with the first. Go to Settings → Applications → Application Management, select the heaviest (e.g. Telegram or TikTok) and click Clear Cache. Repeat for all programs where the cache is greater than 100-200 MB.

For mass cleaning, use the built-in tool:

1. Open Security → Cleanup (or Optimization in newer versions of MIUI).
2. Click Deep Clean and select Cash applications.
3. Confirm the action - the system will show how much space will be vacated.

⚠️ Note: Do not clear the cache in apps with offline content (such as Google Maps or Spotify) – you will have to download maps and music again.

System cache (/cache) It cleans automatically when you restart, but sometimes it requires a manual reset:

1. Turn off the phone.
2. Press Volume Up + Power before the Mi logo appears.
3. From the Recovery menu, select Wipe Cache Partition (use volume buttons for navigation).

This method is secure and does not delete user data, but can speed up the system by 10-15%.

2. Transfer applications to a memory card (if supported)

Many Xiaomi models (especially the budget Redmi and POCO series) support microSD memory expansion. But not everyone knows that applications can be transferred to a card without root rights, but with restrictions. MIUI allows you to move only some programs, and some (such as WhatsApp or Google Play Services) will remain in internal memory.

How to do this:

1. Insert a memory card (UHS-I U3 class is recommended for speed).
2. Go to Settings → Applications → Application Management.
3. Select an app (such as Facebook) and click Move to SD-map.

Important nuances:

• 📱 Not all apps support portability – if the button is inactive, the developer has banned this feature.
• ⚡ Speed may drop if the memory card is slow (class) U1 lower).
• 🔄 After updating MIUI Applications sometimes return to internal memory – check their location every 2-3 months.

For models without a microSD slot (such as the Xiaomi 13 Pro), this method is not suitable, and then it is worth considering cloud storage (about it in the next section).

3.Using Mi Cloud Cloud Storage and Google Drive

If you can’t physically free up your memory, move your files to the cloud. Xiaomi has its own Mi Cloud storage (5GB for free), as well as integration with Google Drive. The main plus is that files remain accessible from any device, and the phone takes up minimal space (only cache for quick browsing).

How to set up Mi Cloud:

1. Open your Settings → Xiaomi Account → Mi Cloud.
2. Enable synchronization for Gallery, Notes and Contacts.
3. In the Gallery section, select Original Quality (if it is important to keep high-quality photos) or High Quality (saves space).

For Google Photos (alternative to Mi Cloud):

• 📸 Install the Google Photos app and enable Backup.
• 🔄 Select “Savings of space” – photos will be compressed, but stored indefinitely for free.
• 🗑️ After downloading, delete local copies through Free up space in the application settings.

⚠️ Note: If you are using Mi Cloud, check what is in Settings → Memory. → Mi Cloud Storage is enabled with the option Optimize Storage, otherwise files will be duplicated on the phone and in the cloud.

4. Removal of duplicates and unnecessary media files

Photos, screenshots and videos often take up to 70% of Xiaomi’s memory, and many files are duplicated (like photos from WhatsApp and the Gallery) or in cache folders (DCIM/.thumbnails). MIUI has a built-in tool to find duplicates, but it doesn’t always find all the extra files.

How to clean media manually:

1. Open the gallery. → Albums. → Folders and check the following directories: Screenshots – screenshots (often hundreds of pieces accumulate), WhatsApp Images / Telegram Images – media from instant messengers. DCIM/.thumbnails — Download - downloads from the browser (especially PDF and APK).

⋮ → Sorting → By size.

For automated search for duplicates, use:

• 🔍 Built-in tool: Security → Cleanup → Duplicate files.
• 📱 Third-party applications: Files by Google or CCleaner (have more flexible settings).

5. MIUI Optimization: Disabling Unnecessary Functions

MIUI is one of the heaviest shells on Android, which constantly creates temporary files, logs and runs background processes, and disabling some features can free up to 1-2 GB of memory and speed up the phone.

What can be safely disabled:

• 📊 Statistics collection MIUI: Settings → The phone. → Send feedback → Shut down.
• 🎵 Musical effects: Settings → Sound. → Sound effects → Disable (saves up to 300MB of cache).
• 📡 Auto-update MIUI: Settings → The phone. → Updating the system → ⋮ → Settings → Downloading.
• 📱 Secondary spatial sound: Settings → Special facilities → Sound. → Secondary spatial sound.

It is also worth limiting the background activity of applications:

1. Go to Settings → Battery and Performance → Battery Management.
2. Select App Selection and disable AutoRun for unnecessary programs (such as games or rarely used instant messengers).

⚠️ Warning: Do not disable auto-runs for system applications (such as Mi Security or Google Play Services) – this can cause crashes.

6.Use of the function "Lite" mode (Lite Mode)

MIUI has a hidden Lite Mode feature that simplifies the interface and reduces memory load, designed for weak devices, but can also be useful on flagships if memory is critically scarce, which disables animations, widgets and some background processes.

How to turn on:

1. Open the Settings. → Special facilities.
2. Scroll down and select Light Mode.
3. Restart your phone and the changes will take effect.

What changes in Lite Mode:

• 📱 Simplified launcher without widgets and animations.
• 🔄 Background updates of most applications are disabled.
• 📊 Reduced use of RAM (up to 20-30%).

The regime's disadvantages:

• 🚫 It is impossible to use certain functions MIUI (For example, Double Apps or Game Mode).
• 🎨 The interface becomes less visual (no transparency, shadows, etc.).

If Lite Mode seems too radical, go back to standard mode the same way. The alternative is to use performance mode in Settings → Battery → Performance mode.

7. Clean up the Android/data and Android/obb folder

Two hidden folders, Android/data and Android/obb, often contain gigabytes of unnecessary files.

• 🎮 Cash games, for example, PUBG Mobile or Genshin Impact can take up to 5 GB).
• 📥 Download data from apps (such as offline Google Maps or Netflix cache).
• 📦 Temporary update files (APK-Files that have not been deleted after installation).

How to clean:

1. Connect your phone to your PC or use a file manager (such as Mi File Manager).
2. Go to the Inner Memory → Android.
3. Remove the contents of the data and obb folders for unnecessary applications (for example, games you haven’t run in a long time).

⚠️ Warning: Do not delete folders completely - only their contents! Android/data will cause applications to fail.

For games with large cache (such as Call of Duty Mobile), it is better to use the built-in cleanup:

1. Open the game.
2. Go to Settings → Clear the cache (or Delete data if the game supports it).

8.Resetting media storage settings

Sometimes Xiaomi indexes media files incorrectly, causing them to be duplicated in the database or displayed incorrectly.Resetting media storage restarts this process and can free up up to 500 MB-1 GB of memory.

How to reset:

1. Open Settings → Applications → Application Management.
2. Press on. ⋮ → Showing System Processes.
3. Find Media Storage and select Storage → Clear Data.
4. Reboot the phone.

After discharge:

• 🔄 Gallery and music players will be temporarily empty (files are in place, just take time to re-index).
• 📊 A place occupied by damaged miniatures and media cache will be freed up.

⚠️ Warning: Don't confuse Media Storage with Google Play Music or Gallery. Clearing up the data in these apps will delete your playlists and settings!

Resetting media storage is a safe way to free up memory, but you’ll have to wait 5-10 minutes for the phone to re-scan files.
