Xiaomi’s “lack of memory”: what to do if the phone is not enough space

The message “Not enough memory”** on Xiaomi smartphones (be it Redmi Note 12, POCO X5 or Mi 11) appears suddenly – and always at the wrong time. You try to install an app, take a photo or update the system, but the phone stubbornly refuses, citing crowded storage.

The fact is that Android (and especially MIUI firmware) reserves some memory for system needs, cache and temporary files. Even if you manually delete all photos and applications, the operating system can “forget” to release occupied blocks. In this article, 10 proven ways to clear memory on Xiaomi without resetting to factory settings, including hidden MIUI features and tools for power users.

Importantly, some methods require root rights or PC connectivity, and we've tagged them with special tags so you can choose the best option without risking data damage, and let's start with the simplest and most secure solutions.

1. Cleaning the application cache and system

Cash is Xiaomi’s main memory eater, and it accumulates invisibly: browsers, social networks, instant messengers, and even system processes create temporary files that take up gigabytes over time, and MIUI does not always correctly display them in the Storage section.

How to clear the cache without losing data:

• 📱 For individual applications: go to Settings → Annexes → App management, select the one you want (such as Telegram or Chrome) and click Clear Cache».
• 🧹 System cache: in the same application settings, tap three points in the upper right corner → «Clear the cache of all applications».
• 🔄 Cash updates: MIUI Often leaves behind update files weighing 1-3 GB. Delete them in Settings → The phone. → Updating the system → Three points. → Remove the downloaded package.

⚠️ Warning: Don’t confuse “Clear Cache” with “Clean Data”! The second option will remove all the app settings (such as WhatsApp chat history or browser bookmarks).

2. Transfer applications and files to SD-map

If your Xiaomi supports memory cards (such as the Redmi 10C or POCO M4 Pro), transferring data to a microSD can free up to 50% of internal memory.

• 📲 Not all programs can be transferred to SD. To do this, go to the Settings. → Apps, select the desired and click "Move to" SD-Card (option is not active for all applications).
• 📁 Photo and video: Use the built-in Gallery app: highlight files → «More» → «Move it» → choose SD-map.
• 🎵 Music and Documents: In the File Manager MIUI (My File Manager) Hold the folder, click “Slice” and paste into the section SD-map.

⚠️ Attention: Class Memory Cards UHS-I (Grade 10 and above are faster, but even they slow down application performance by 20 to 30 percent.

3. Delete unnecessary system files

MIUI creates many hidden files that are not displayed in the standard manager.

• 🗑️ Log files (.log): take up to 1 GB in a folder /sdcard/MIUI/debug_log.
• 🎬 Video miniatures: folder /sdcard/DCIM/.thumbnails weigh 500+ MB.
• 📦 Remnants of Remote Applications: Folders of the View /sdcard/Android/obb/com.game.name.

To remove them:

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. Manually remove folders from the list above (pre-return!).

💡 Use Files by Google (available on the Play Market) to automatically search for garbage, and it finds duplicates, large files and cache that you can’t see in the standard manager. MIUI.

4.Storage optimization through MIUI settings

Xiaomi has built memory cleaners into the firmware, but they're hidden deep in the menu.

1. Storage analysis: Go to Settings → Storage. All file categories (applications, images, videos, etc.) are displayed here. Tap any category to see details and delete unnecessary ones.
2. Clean up garbage: In the same Storage section, click Clean up → Unnecessary Files. MIUI will find cache, temporary files and remnants of deleted applications.
3. Optimization of photos: In Gallery → Albums → Tools → Free up space system will offer to remove blurred pictures, screenshots and duplicates.

⚠️ Attention: Free space in the Gallery sometimes deletes photos that seem to the system "unsuccessful" (for example, with your eyes closed!

Instructions for Windows:

1. Download ADB Tools and unpack it into the C:\adb folder.
2. On your phone, turn on USB Debugging (Settings → About Phone → MIUI Version → 7 times tap on version → return to “Additional” → “Developers” → turn on debugging).
3. Connect the phone to your PC, open the command prompt in the adb folder and type: adb shell pm clear --user 0 com.miui.home This will clear the MIUI launcher cache, which often takes up to 500MB.

Critical information: Adb shell pm clear commands for system applications (e.g. com.android.providers.media) can cause gallery or contacts to fail. Use them only if you are confident in action!

6.Reset to factory settings (last chance)

If none of the methods worked and the phone still gives you an error "Not enough memory"** even with 5+ GB of free space, you'll have to reset hard, and that will delete all the data, so first:

• 🔄 Make a backup copy through Settings → Additionally. → Backup and reset → Local backup.
• ☁️ Sync contacts, photos and notes with Mi Cloud or Google Account.
• 📱 Remember the usernames and passwords from the applications (they will be deleted!).

For discharge:

2. Select “Erase all data” and confirm the action.
3. After the reboot, the phone will be like new – with full memory and no debris.

💡

Factory reset is a last resort, and 90 percent of the time, the solution is to clear the cache, transfer files to the cache. SD-map or delete hidden system files.

To prevent the “Not enough memory” error from appearing, follow the following simple rules:

• 📱 Clear the cache once every 2 weeks (use Files by Google or built-in tools) MIUI).
• ☁️ Automatic upload to the cloud: Set up autoload photos in Google Photos or Mi Cloud and delete local copies.
• 🚫 Limit background activity: In Settings → Battery → Battery mode disable Background Activity for unnecessary apps.
