Cache Clearing on Xiaomi Redmi Note 8: 5 Proven Ways

Xiaomi Redmi Note 8 gets more slow, warmer and discharged over time, because of cache clogs. This temporary memory stores app data to speed up their work, but eventually turns into digital garbage. If you notice that the device has become slower to respond to commands and free space on the disk is melting in front of your eyes, it's time to clean the cache.

In this article, you will find 5 working methods for cleaning the cache on the Redmi Note 8, including hidden MIUI features that not everyone knows. We will discuss how to remove the cache of individual applications, the system cache through Recovery, and even how to automate the process with third-party utilities. Importantly, some methods require caution - wrong actions can lead to a reset or data loss.

Why Redmi Note 8 cache should be cleaned regularly

Cache is a temporary file that creates applications to speed up its work, for example, when you open Instagram, it saves thumbnails of photos so that the next time it runs, it shows them faster, the problem is that over time these files accumulate, taking up gigabytes of memory, and the benefit from them tends to zero.

On the Redmi Note 8 with its 64/128 GB of memory and Snapdragon 665 processor, the cache is as follows:

• 🐢 Smartphone starts to “suppress” when switching between applications.
• 🔥 The device overheats even with minimal load (for example, during a call).
• 📉 The battery sits on 20-30% faster than usual.
• 🚫 Applications suddenly close or issue a “Mismemory Lack” error».

Tests show that after cleaning the Redmi Note 8 cache, it runs 15-20% faster and battery life increases by an average of 1-1.5 hours, but there’s a nuance: cleaning the system cache through Recovery resets some MIUI settings (such as regional settings and application permissions), which are often not mentioned in standard instructions.

Method 1: Clearing the cache of individual applications through settings

The safest method is to remove the cache for specific programs, which does not affect system files and does not require a reboot, but is suitable if only one application (such as Telegram or Google Chrome) is slowed down.

Instructions:

1. Open Settings → Applications → Application Management.
2. Select the appropriate app (such as Facebook).
3. Press Warehouse.
4. Tap Clear Cache (not to be confused with Clear Data – this will remove all app settings!).

For convenience, sort the applications by cache size:

Enable the display of system applications (three dots in the upper right corner)

Sort the list by size (click on "Size")

Check the top-5 applications with the largest cache

Do not clear the cache for Google Play Services and MIUI System without the need to-->

⚠️ Warning: Do not clear the cache for Google Play Apps Store and Google Play Services unless absolutely necessary.This can lead to update errors and push notification issues.

Method 2: Automatic cleaning through the built-in MIUI utility

Xiaomi Redmi Note 8 runs on the proprietary shell MIUI, which has a built-in optimization tool — Security. It can not only clean the cache, but also delete unnecessary files, remnants of deleted applications and duplicate photos.

How to use:

1. Open the Security app (the shield icon).
2. Go to the Cleanup tab.
3. Wait for the scan to be completed (usually 10-30 seconds).
4. Click Clean next to Cash.
5. For deep cleaning, tap Deep Clean and select unnecessary files manually.

The advantage of this method is that it analyzes all types of garbage, not just the cache of applications.

• 🗑️ Residual files after uninstallation of programs (.apk,.obb).
• 📁 Empty folders and temporary files (.tmp,.log).
• 🔄 Duplicate photos (if the appropriate option is enabled).

💡

After cleaning through Security, restart your smartphone. This will help MIUI recalculate the free space and avoid memory glitches in the settings.

Method 3: Cleaning the system cache with Recovery Mode

If the Redmi Note 8 is getting unbearably slow and standard methods are not helping, it’s time to clean the system cache (called Dalvik-Cache), a radical method that resets optimized data for all applications but doesn’t affect user files.

Instructions:

1. Turn off your smartphone.
2. Press the Power Button + Volume up at the same time and hold for 10 seconds until the MI logo appears.
3. In the Recovery menu, select the language (usually English or ).
4. Go to Wipe & Reset → Wipe Cache.
5. Confirm the action and wait for the completion (it will take 1-2 minutes).
6. Choose Reboot. → Reboot to System.

After the reboot, the smartphone will work faster, but:

• 🔄 The first application launch will take longer (they will reassemble the cache).
• ⚙️ Some settings MIUI They will be replaced (e.g. regional parameters).
• 📱 You may need to re-enter Wi-Fi passwords.

⚠️ Warning: Don't confuse Wipe Cache with Wipe Data! The second option will completely reset the smartphone to factory settings, deleting all your data.

Method 4: Use of third-party applications (CCleaner, SD Maid)

If you don't like the built-in MIUI tools, you can use third-party tools that offer more flexible settings and often find garbage that a standard cleaning service misses.

• 🧹 CCleaner – removes cache, call history, SMS and residual files.
• 🤖 SD Maid – Looks for duplicates, empty folders and cache of system applications.
• 🚀 Files by Google: Google’s Simple Tool With Cleanup Function.

Example of working with SD Maid:

1. Install the app from Google Play.
2. Start and grant the rights of the Super User (if there is root).
3. Go to the CorpseFinder tab (search for residual files).
4. Press Run and wait for the scan to be completed.
5. Select unnecessary files and tap Delete.

Warning: Apps like CCleaner often collect user data, and if you care about privacy, use SD Maid (it works locally) or built-in MIUI tools.

💡

Cleanup utility side can delete critical files of system applications. Always check the file list before deleting and back up important data.

Method 5: Manually clean the cache through the file manager

For power users, there is a method of manually cleaning through a file manager (such as Mi File Explorer or Solid Explorer), which allows you to pinpoint the cache of specific applications without affecting the rest of the data.

How to do this:

1. Open the file manager and enable the display of hidden files (in the settings).
2. Go to /storage/emulated/0/Android/data/ This is where application data is stored.
3. Find a folder with the name of the problem app (e.g. com.whatsapp for WhatsApp).
4. Delete the cache folder inside it.

Alternative path for system cache (requires root rights):

/data/dalvik-cache/

It stores optimized files for all applications, and deleting this folder is equivalent to clearing the cache through Recovery, but without rebooting to a special mode.

⚠️ Note: Delete files in the folder /data/data/ root-free can cause app failure. Don't change files outside of cache if you're not sure what you're doing.

Frequent Mistakes and How to Avoid Them

Clearing the cache seems like a simple procedure, but many users make mistakes that only make things worse.

Another common problem is that the cache comes back right after cleaning, and this happens if:

• 📱 The application actively uses the Internet (for example, TikTok or YouTube).
• 🔄 Automatic sync enabled (for example, for Google Photos).
• 📌 App added to Auto Run (check in Settings) → Annexes → Auto-start).

Solution: Turn off auto-run for unnecessary apps and limit background activity through Settings → Battery → Background Limitation.
