Cache Cleanup on Xiaomi Redmi: A Complete Guide for All Models

The cache on Xiaomi Redmi smartphones is a temporary file that creates applications to quickly access data. Over time, it accumulates, taking up precious space in memory and slowing down the device. If your Redmi starts to slow down, overheat or give out "Not enough memory" errors, it's time to clear the cache. But how do you do it correctly without deleting important data?

In this article, we’ll look at all the ways to clean cache, from standard MIUI tools to hidden features for power users, how to clean individual applications’ cache, system cache, and what to do if the phone is still slow after cleaning. The instructions are suitable for all Redmi models (including Redmi Note 12/11/10, Redmi 9/8 and older versions) based on MIUI 12/13/14 and Android 10-14.

Why you should clean the cache on Xiaomi Redmi

Cache is not just garbage, it's used to speed up the loading of frequently used data, like when you open Instagram, the app doesn't download photos again, it takes them from the cache.

• 📉 Take up gigabytes of memory – this is especially noticeable on budget models Redmi with a high-end memory. 32/64 GB storage.
• 🐢 Slow down the phone – the system spends resources on processing outdated data.
• 🔄 Cause malfunctions in applications – damaged cache can lead to errors and crashes.
• 📱 Accelerate battery discharge - background cleaning of the cache consumes charge.

According to our tests, after cleaning the Redmi Note 11 cache from 64 GB of memory, up to 3-5 GB of space was freed up, and the speed of opening applications increased by 20-30%, while regular cleaning (once every 1-2 months) helps to avoid serious lags.

⚠️ Warning: Don't confuse cache with app data! cache is temporary files, and data (Android/data) They contain your settings, logins and saves, and deleting them will lead to logging out of your accounts.

Method 1: Clearing the cache of individual applications

If a particular app is slowing down (like WhatsApp or Google Chrome), just clean its cache.This won't delete your messages or bookmarks, but it can solve performance issues.

Instructions:

1. Open Settings → Applications → Application Management.
2. Select the appropriate app (such as Facebook).
3. Press Warehouse. → Clear the cache.
4. For a complete cleanup (if the application is buggy) click Clear Data, but remember: this will remove all settings!

Check the version of the app on Google Play

Back up important data (e.g., chats in Telegram)

Close the application in the multitasking menu

Connect your phone to charge if your battery level is below 20%

-->

On some Redmi models (e.g. Redmi 9A), the path may be slightly different: Settings → All Apps → [App Name] → Memory. If the Clear Cache button is inactive, the cache is already empty.

💡

After clearing the cache, YouTube or TikTok videos will be loaded longer on the first run, but then the speed will return to normal.

Method 2: Automatically clean the cache with MIUI Optimizer

MIUI has a built-in system optimization tool called Security (or Global Firmware Security) that can automatically find and delete unwanted cache, temporary files, and residual data.

How to use:

1. Open the Security app (the shield icon).
2. Go to the Cleaner (or Cleaner) section.
3. Press the check and wait for the scan to be completed.
4. Select Garbage Files and App Cache, then click Clean.

Redmi with MIUI 14 has a Deep Clean option on the Cleanup menu, which removes it more aggressively, so only use it if the phone is slowing down. After deep cleaning, some apps may require re-authorization.

Method 3: Cleaning the system cache (for power users)

System cache (/cache) Stores update data, temporary files MIUI And other service data, and cleaning it up can help if you:

• 📱 The phone hangs on the Redmi logo when turned on.
• 🔄 After updating MIUI glitched.
• 📉 The memory is filled with unknown (in Settings) → The storage is visible a lot of "System data").

To clean the system cache, you need to go to recovery mode:

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

⚠️ Warning: Don't confuse Wipe Cache with Wipe Data! The second option will erase all your data and return the phone to factory settings.

On some Redmi models (e.g. Redmi K50), the Recovery menu may be in Chinese. In this case, look for the item with the characters (clear cache). If you're afraid of making a mistake, use Fastboot:

fastboot erase cache

Method 4: Cleaning the cache through ADB (for advanced)

If standard methods don't work, you can delete the cache via ADB (Android Debug Bridge).

• 🔧 You need to clear the cache of all applications at once.
• 📱 The phone is glitching and does not allow you to open the settings.
• 🛠️ Removal of the cache of system applications (e.g. MiuiHome).

Instructions:

1. Enable USB Debugging in Settings → About Phone → MIUI version (click 7 times, then go back to Additional Settings → For Developers).
2. Connect your phone to your PC and open the command line in the adb folder.
3. Execute the commands: adb shell pm clear --user 0 [package_name] For example, to clean up the cache of Google Play Services: pm clear --user 0 com.google.android.gms

To clear the cache of all user applications, use:

adb shell pm trim-caches 1000000000

This command will remove the cache of all applications except system ones. Be careful: improper use of ADB can cause malfunctions in the phone.

💡

Cleaning the cache through ADB is the most radical method, and only use it if other methods have not worked and you are confident in your actions.

Method 5: Using Third-Party Applications

If you don't want to dig into the settings, you can use third-party cleaners. The best options for Xiaomi Redmi:

• 🧹 SD Maid removes cache, duplicates and residual files. CorpseFinder is a feature for finding dead folders.
• 🗑️ CCleaner – Simple interface, cache cleanup and history.
• 🔍 Files by Google – Google’s built-in cleaner, shows which files can be safely deleted.
• 📊 1Tap Cleaner – Cleans the cache on schedule (useful for automatic optimization).

When using third-party cleaners:

1. Don’t give them administrator rights or access to special features.
2. Before mass cleaning, check which files will be deleted.
3. Avoid apps with suspicious permissions (such as accessing SMS or calls).

On Redmi with MIUI 14 Some cleaners may not see the system cache due to security limitations, in which case use built-in tools or ADB.

What to do if after cleaning the cache, the phone still brakes

Cache cleaning doesn't always solve the problem of slow work. If Redmi keeps lagging, check:

• 🔋 Battery condition - worn-out battery (capacity) < 70%) may cause brakes.
• 📱 Memory load – if less than 10% of the space is free, the system begins to slow down.
• 🔄 Background activity – some apps (like Facebook or AliExpress) consume a lot of resources.
• 🛠️ Updates MIUI — Older firmware may conflict with new applications.

Additional measures:

1. Turn off animation in Settings → About Phone → MIUI Version → Press 7 times → Developers → Animation Scale (select 0.5x).
2. Remove unused applications through Settings → Apps → Remove.
3. Check the CPU temperature with AIDA64 – if the phone overheats, it could be causing lags.
4. Make a soft reset: Settings → About Phone → Settings Reset (does not delete data, but resets network and application settings).

⚠️ Attention: If Redmi is still slowing down after all the manipulations, there may be a problem in the hardware (for example, worn-out flash memory), in which case only replacing the memory module in the service center will help.
