Xiaomi Redmi 9A Cleanup: 7 Proven Ways to Free Your Memory

Xiaomi Redmi 9A is one of the most popular budget smartphones, but its 32 GB of internal memory is quickly clogged with unnecessary files. If your device starts to slow down, give out errors "Insufficient memory" or spontaneously close applications, it's time to do a general cleaning. In this article, we will analyze all possible cleaning methods, from standard MIUI tools to hidden functions and third-party utilities.

The Redmi 9A feature is the lack of a memory card slot in the base version (there is a modification with microSD support), which means that users are forced to carefully monitor the free space. We will not limit ourselves to the banal advice “delete unnecessary photos” – we will focus on system methods that give maximum effect with minimal effort.

1. Built-in cleaning MIUI: latent

The manufacturer has put a powerful cleaning tool in MIUI, but many of the features are hidden in the back of the menu.

1. Go to Settings → About the phone → Memory
2. Click "Clean" in the "Junk Files" section
3. Wait for analysis and confirm removal

But this method only removes surface debris.

• 🔍 Go to Settings. → Annexes → Application management
• 📊 Sort by size (button in the upper right corner)
• 🗑️ Select apps with large cache (e.g. YouTube, Facebook) and click Clear cache"
• 🔄 For system applications (such as Gallery), use Clear Data – but beware, this will reset the application settings.

💡

After clearing the Google Play Services cache, the smartphone can temporarily run slower - that's normal. Performance will recover in 10-15 minutes.

Few people know that Redmi 9A has a hidden deep-cleaning menu to open it:

In the menu that appears, select Storage, where you can manually delete temporary files of system processes that are not normally visible to the user.

2. Cleaning the Dalvik and ART cache: Accelerating the system

The most effective, but risky, method is to clean the Dalvik and ART cache, which are system files that optimize applications, and when they are cleaned, they will cause the system to reassemble the cache, which can:

• ⚡ Accelerate the work of the smartphone 20-30%
• 🗃️ Release until 1-2 GB space
• ⚠️ Lead to the first longer on (up to 5 minutes)

Instructions:

1. Turn off your smartphone.
2. Press the Power button + Volume up before the Mi logo appears
3. From the Recovery menu, select Wipe & Reset → Wipe Cache
4. Confirm the action and restart the device

⚠️ Warning: If after this procedure, the smartphone hovers on the logo for more than 10 minutes, don't panic. This is normal at the first start!

3. Removal of system applications without root

Redmi 9A by default clogs memory with unnecessary system applications (Mi Video, Mi Music, GetApps, etc.) They can not be deleted by standard methods, but can be disabled or deleted via ADB.

Try turning off first:

1. Go to Settings → Applications
2. Select an unnecessary app (e.g. Mi Pay)
3. Press "Disable" (if the button is active)

A computer will be required to remove the entire system and ADB-tool:

adb shell pm uninstall -k --user 0 com.xiaomi.videoplayer

⚠️ Warning: Deleting com.miui.securitycenter or com.xiaomi.finddevice may disrupt Find My Device and antivirus protection.

4.Storage optimization through computer

Sometimes it's easier to connect Redmi 9A to a PC and clean it manually, and this method allows you to:

• 📁 See hidden system folders
• 🔍 Find duplicate files
• 🗑️ Delete files that are not visible through the smartphone explorer

Instructions for Windows:

1. Connect your smartphone via USB (select File Transfer mode)
2. Open this computer. → [Your phone name]
3. Go to the folders: DCIM\.thumbnails — Photo miniatures (can be deleted) Download - downloads from the browser Android/data — cache of games and applications

For in-depth analysis, use WizTree (the portable version does not require installation) and it will show:

• 📊 The largest files on the device
• 🗃️ Folders with the most small files
• 🔍 Duplication files by hash amount

5. Factory reset: When nothing helps

If all the previous methods failed, the last option is hard reset, which will completely clean the smartphone, return it to the "out of the box" state. On the Redmi 9A, there are two ways to reset:

Method 1. Through the settings menu (if the smartphone works):

1. Settings → About the phone → Resetting settings
2. Select "Reset all settings"
3. Enter the password (if set)
4. Confirm the action.

Method 2. Through Recovery (if the smartphone is not turned on):

1. Turn off the device.
2. Press the power button + Volume up
3. In the menu, select Wipe Data. → Wipe All Data
4. Confirm the action and wait for the reboot

⚠️ Attention: On Redmi 9A s MIUI 12.5+ After reset, you may need to enter a password from the last Google account you used, and if you don’t remember it, use Google’s recovery service before reset!

6. Alternative methods: what else can be done

If the standard methods did not help, try these non-obvious techniques:

• 📱 Transfer applications to a memory card (if your model supports microSD): Insert a memory card (class 10 recommended) Go to Settings → Applications Select the Application → "Warehouse" → "Change" → "Map. SD"

Cloud storage

• Activate Mi Cloud (5GB for free)
• Use Google Photos with High Quality compression (unlimited storage)

Reversing to the previous version of MIUI

Sometimes newer versions of firmware contain memory clogging bugs, and you can return the old version via fastboot, but it takes experience.

For advanced users, there is another way to change the cache partition via TWRP. This allows you to increase user memory due to the system memory, but requires:

• Unlocked loader
• Established custom recaveri
• Backup of all data
• 🔄 Set up automatic cleaning: Settings → The phone. → Memory. → Autoclean: Enable the option and set a schedule (e.g. once a week)

• On WhatsApp: Settings → Storage → Autoload media
• In Telegram: Settings → Data and memory → Autoboot media
