Cache Cleanup on Xiaomi Redmi 6A: 5 Ways to Get Back Performance

Xiaomi Redmi 6A is one of the most popular budget smartphones of the brand, but over time even it begins to slow down. The main reason is clogged cache, which takes up precious memory and slows down the system. In this article, you will find unique methods of cleaning the cache for Redmi 6A, taking into account the features of MIUI 9-14, including hidden functions and bypassing the manufacturer’s limitations.

Many users mistakenly believe that it is enough to clear the cache through application settings, which in practice solves only 30% of the problem, we will analyze the system cache, Dalvik cache (critical for performance), and also tell you how to safely remove garbage without risking damage to data. We will pay special attention to Redmi. 6A 16 GB of memory – here every megabyte counts!

Why Redmi 6A is slowing down: is it the cache that is to blame?

On the Redmi 6A with a Helio A22 processor and 2 GB of RAM, the cache plays a dual role: on the one hand, it speeds up the re-launch of applications, on the other hand, it becomes a ballast when overflowing.

• 🐢 Applications open long (more than 3-5 seconds)
• 🔄 Spontaneous reboots when you start your camera or games
• 📱 Message “Insufficient Memory” when installing updates
• 🔋 Fast battery discharge (cache makes the processor work harder)

According to Xiaomi tests, the Redmi 6A with 16 GB of memory can take up to 4-6 GB – almost a third of the total! while the MIUI system hides some of the cached data from the user to “smooth” the statistics of memory usage.

⚠️ Warning: If the phone gets worse after cleaning the cache, it's a sign of memory fragmentation, and only a complete reset will help (see Section 6).

Method 1: Clearing the cache of individual applications

The safest method, which does not require superuser rights, is suitable for removing garbage from messengers, social networks and games.

1. Open Settings → Applications → Application Management.
2. Slip on the three dots in the upper right corner and select Sort by size.
3. Select an app (like Facebook or Telegram) and click Clear Cache.
4. For complete cleaning, click Clear Data (⚠️ This will remove all settings and accounts in the application!).

Make a backup copy of important data (chats, photos)

Close all background applications

Check the vacant space (should be ≥ 500 MB)

Method 2: System Cleaning through “Safety”

MIUI has a built-in garbage cleaner, but it doesn't work properly by default, to unlock its potential:

1. Go to Settings → Security → Cleanup.
2. Press Deep Clean (not fast!)
3. Turn on the boxes opposite: 🗑️ «Cash app» 📁 «Unnecessary files APK» 🔍 «Residual files" (these are fragments of remote applications)

Clean up

Secret trick: If the cleaning menu doesn’t show all the items, try:

1. Reboot the phone.
2. Open Settings → About the phone and 7 times tap on the version MIUI (Unlocks hidden options).

💡

After deep cleaning, restart the phone – this will allow the system to reassemble the Dalvik cache and speed up work by 15-20%.

Method 3: Cleaning Dalvik cache (for advanced)

Dalvik cache is an optimized version of the application that the system creates to speed up its work. On Redmi 6A, it is often corrupted, leading to lags.

1. Turn off the phone.
2. Press Volume Up + Power before the Mi logo appears.
3. From the Recovery menu, select Wipe & Reset → Wipe Cache (use volume buttons for navigation, power for selection).
4. Confirm the action and wait for the completion.

⚠️ Warning: Do not confuse Wipe Cache with Wipe Data! The second option will erase all your data, including photos and contacts.

Once the Dalvik cache is cleared, it takes up to 10 minutes for the system to start, which is normal.

• ✅ Accelerate application opening by 25–40%
• ✅ Errors like “The application is stopped»
• ❌ Temporary increase in battery consumption (the system reassembles the cache)

Method 4: Manually Delete Cache Through File Manager

Some cache files (.thumbnails,.nomedia) are not deleted by standard methods.

1. Install a file manager with access to system folders (such as FX Explorer or Solid Explorer).
2. Go to /data/data/ (root rights required!) or /sdcard/Android/data/ (no root required).
3. Delete the folders with the names: 📂 com.android.providers.media (cache of thumbnails) 📂 com.miui.gallery (galleries cache) 📂 com.tencent.mm (weChat cache, if installed)

Safe alternatives: If root rights are not available, clean at least these folders (accessible without rights):

• 📂 /sdcard/DCIM/.thumbnails (photo-picture)
• 📂 /sdcard/Android/obb/ (game-cash)

Method 5: Automatic cleaning with ADB

For users familiar with ADB (Android Debug Bridge), there is a powerful method of clearing the cache of all applications with one command.

• 🖥️ A computer with installed Xiaomi drivers and ADB
• 📱 Included debugging by USB on the Redmi 6A (Settings → The phone. → Version. MIUI → 7 times to tap → return to → For developers → Debugging by USB)

Cleanup commands:

adb shell pm list packages -f | grep cache | cut -f2 -d= | xargs -n1 adb shell pm clear

This team:

1. Gets a list of all the cache packets.
2. Clears the cache for each of them.

⚠️ Attention: The team will clear the cache of all applications, including system ones. Once it is done: You will have to re-sign in to accounts (Google, Mi Account, etc.) Some applications may request an update. The first launch of the system will take 3-5 minutes.

💡

ADB-Cleaning is the most radical method, but it brings back Redmi 6A to the “factory” cache state without data resetting.

What if cleaning the cache doesn’t help?

If Redmi 6A continues to slow down after all the manipulations, the problem lies deeper.

Extreme measures for Redmi 6A:

1. Recoil to the factory firmware through the Mi Flash Tool (loss of all data).
2. Install custom firmware (like LineageOS), but this requires unlocking the bootloader.
3. Memory replacement (if the phone is older than 3 years, flash memory may wear out).
