"Memory is full."

7 Proven Methods

MIUI

Many users mistakenly believe that it is enough to delete a few photos or clear the basket, but this has a temporary effect. In fact, up to 40% of the memory on the Mi 6A is occupied by hidden files: the Google Play Services cache, the system logs /data/log, duplicates in DCIM/.thumbnails and the remnants of MIUI updates. We will figure out how to find and safely remove this garbage, and also prevent it from being re-accumulated.

Unlike flagships, the Mi 6A does not support microSD cards as its primary storage (only as a portable device), so optimizing internal memory is critical here. If you have never cleaned a smartphone since you bought it, after completing all the steps in this article, you can free up 3 to 8 GB – enough to install 10-15 new apps or shoot 1000+ photos in high resolution.

1. MIUI Integrated Tools: Cleaning Cache and Garbage

Start with standard MIUI features that don’t require third-party apps to be installed. The Mi 6A has two key tools: Clean (in the security menu) and Storage in the settings. The first deletes temporary files, the second helps you find large, unnecessary data.

Open the Security app (shield icon) and go to Cleanup, where the system scans the device and shows you:

• 🗑️ Application cache - temporary files that can be deleted without consequences. 6A frequently 1-3 GB.
• 📁 Unnecessary APK — Remains of installed applications (for example, after updating via.apk).
• 📄 Logs and reports – files with information about failures (/data/anr, /data/tombstones).

Click Clean, which will free up 500MB-1.5GB in a few seconds, and it is important that some apps (like Google Maps or YouTube) cache will recover the next time it runs, but its size will decrease.

Next, go to Settings → Storage. Here you can see detailed statistics by category:

• 🎵 Audio - check the Ringtones and Notifications folder. Often there are duplicates of tunes.
• 📷 Images – click on category, then “Others” – there may be screenshots, memes and uploaded pictures from messengers.
• 🎮 Apps – sort by size and remove unused ones (more on this in the next section).

💡

If you see a 5+GB System category in the Storage section, don’t try to manually clean it, these are critical MIUI files, and deleting them will cause a download failure.

2. Removal of unnecessary applications and their residues

The Mi 6A has a lot of Xiaomi and Google system apps that can’t be removed by standard means, but you can disable or uninstall updates, such as Mi Video, Mi Music, Browser, and Google backup services (e.g. Google Play Music if you use YouTube Music).

To find and remove unnecessary programs:

1. Go to Settings → Applications → Application Management.
2. Sort the list by size (click on the three dots in the upper right corner).
3. Select the application → “Delete” (or “Disable” if the delete button is inactive).

Pay particular attention to:

• 📱 Social media sites like Facebook, TikTok, Instagram are cacheing gigabytes of video. Delete them and use Lite versions or websites.
• 🎮 Games – even remote games leave files in the /Android/obb and /Android/data. Check these folders through the file manager.
• 🔄 System App Updates – Google Play Services can weigh 500+ MB. Go to Settings. → Annexes → Google Play Services → Warehouse → Management of space → Remove updates.

Warning: Do not disable system services called com.android. or com.miui. (e.g. Mi Account or System UI) – this will cause the interface to fail. If in doubt, check the app name on Google before disabling.

3. Hand-cleaning folders: Where to look for hidden trash

Even after using the built-in tools, the Mi 6A still has files that MIUI doesn't recognize as garbage, and can be found and removed manually through a file manager (like the standard Files or FX File Explorer).

To access hidden folders (starting from a point, such as.thumbnails) in the standard MIUI file manager, enable the display of hidden files: click on three dots → Settings → Show hidden files.

Do not delete /efs, /persist or files with the.qcow2 extension, which will result in loss of IMEI or inability to boot the system.

4.Photo and video optimization: compression without loss of quality

The gallery on the Mi 6A can take up to 10GB — especially if you’re shooting Full HD videos or taking a lot of.png photos.

Method 1: Integrated compression in MIUI

• 📷 Open the Gallery appendix" → select the album → press three points → "Squeeze".
• 📊 Select quality ("High" retains 80% of the original, "Mediocre" - 50%).
• ⚠️ Originals will be replaced with compressed copies (create a backup in advance!).

Method 2: Using Google Photos

Method 3: Video conversion

Videos in 1080p weigh ~100MB/minute. Use the Video Compress app (available in the Play Market) to compress up to 720p (saving up to 60% of space). Alternatively, FFmpeg via Termux (for advanced users):

ffmpeg -i input.mp4 -vcodec libx264 -crf 28 -preset fast -acodec aac -b:a 128k output.mp4

5. Transfer data to external media (if there is an OTG adapter)

Xiaomi Mi 6A It does not support microSD as a memory extension, but you can connect a flash drive through the OTG-adapter (or external adapter) SSD) And then we can transfer the heavy files to it:

1. Buy it. OTG-adapter (Type-C) → USB-A, worth ~200 rubles).
2. Connect the flash drive to your phone. In the notification, select "Use as a portable storage".
3. Open Files → select folders (such as DCIM or Download) → Copy → select a flash drive.

After transferring, do not delete files from your phone immediately - check that they open from a flash drive. To automatically save the photo to an external drive, use the FolderSync application (set the task to copy from the flash drive). /DCIM/Camera flash-drive).

Limitations of the method:

• ⚠️ Applications cannot be transferred to a flash drive – only media files and documents.
• ⚠️ Read/write speed through OTG lower than the internal memory (especially on cheap flash drives).

💡

OTG-Adapter is a temporary solution, for permanent expansion of memory on Mi. 6A Only a replacement of the storage module is suitable (requires rations and risky).

6. Reset to factory settings: when necessary

If you've got less than 1GB of free time after all the manipulations, and your phone is laying down, it's time for a hard reset, which will delete all the data, including your accounts, photos and apps, but it will return the device to a "clean" state, and on the Mi 6A, the reset is done like this:

1. Back up your important data (export your contacts to.vcf, send your photos to your PC or cloud).
2. Go to Settings → About Phone → Resetting → Erase all data.
3. Enter the password (if set) and confirm the reset.

What will be removed:

• 📱 All installed applications and their data.
• 📇 Contacts, SMS, Call logs (if not synced to Google).
• 📷 Photos and videos in folders DCIM, Pictures, Download.
• 🔑 Wi-Fi passwords, Bluetooth settings.

What's left:

• 📱 Pre-installed annexes MIUI Google.
• 📶 Files on an external flash drive (if connected via OTG).

⚠️ Attention: After the Mi is discharged 6A You may need to enter a Xiaomi account linked to the device. If you forget your password, unlocking will require confirmation through the device. SMS Or email, or an account, without it, the phone becomes a brick".

7.Preventing the filling of memory in the future

To avoid clearing your memory every 2-3 months, set up the Mi 6A to auto-optimize:

• 📱 Cleaning the cache on schedule: C "Security" → "Cleanup" → "Settings" turn on "Auto Clean" (select frequency: weekly or low memory level).
• 📷 Restriction of photo quality: Set resolution 8 in the camera MP 12 MP (The difference in detail is minimal and the weight of the photo will decrease by 30%).
• 🎮 Limiting the cache of games: In Google Play, open the settings → "Auto-update of applications" → Select “Only via Wi-Fi” and disable “Automatic video playback".
• 🗑️ Remove duplicates: Install Files by Google (free in Play Market) – it automatically finds duplicate files.

It is also useful to disable automatic downloading of media in messengers:

• 📱 WhatsApp: Settings → Warehouse → Autoboot media → disconnect for mobile data.
• 📱 Telegram: Settings → Data and memory → Autoboot media → Choose "Never".

💡

Regular cache cleaning and disabling autoload media in messengers extends the memory life of the Mi 6A by 30-50%.
