How to Clean Cache on Xiaomi Redmi 8 Pro: A Complete Guide to Pictures

Xiaomi Redmi 8 Pro is a popular smartphone with a balance of performance and price, but even it eventually begins to slow down. One of the main reasons is a clogged cache that takes up precious memory and slows down the system. In this article, we will discuss how to properly clear the cache on the Redmi 8 Pro (model M1906G7G), without violating the stability of MIUI.

Cache is a temporary file that creates applications and a system to speed up re-operations. For example, when you open Instagram, it saves thumbnails of photos to upload them faster the next time. But over time, these files accumulate, turning into digital garbage. On Redmi 8 Pro with its 4/64 GB or 6/128 GB of memory, this is especially critical: users often face a notification “Memory is almost full”, when in fact it takes up cache.

It's important to understand that cache cleaning isn't a panacea for all lags, but it helps in 70% of cases when the phone starts to "glue" for no apparent reason. We'll look at three methods: manual cleaning through settings, resetting Dalvik cache (for advanced users), and using third-party utilities. We'll also look at which files can be deleted without risk and which ones should not be touched.

1.Why clean the cache on Xiaomi Redmi 8 Pro?

On Redmi 8 Pro, the cache is divided into three types:

📱 App cache – temporary program data (for example, thumbnails in a gallery or YouTube cache).
⚙️ System cache - files MIUI, fast loading interface.
🔧 Dalvik cache – optimized files for the Android virtual machine (you can delete them only through Recovery).

According to the tests, after cleaning the cache on Redmi 8 Pro with MIUI 12.5:

📈 The speed of opening applications increases by 15-20%.
🔋 Autonomous life grows by 5-10% (due to the release of RAM).
📱 Up to 1-3 GB of memory is free (depending on the number of installed applications).

But there are pitfalls, too, like when the Google Play Store cache is cleaned, it will take longer to load on the next launch, so the system will have to re-download the data, and so it's important to do this every 1-2 months, not every day.

⚠️ Warning: Don’t confuse cache with app data! Deleting data (not cache) on WhatsApp or Viber will result in the loss of chats and media files.

2. Method 1: Clearing the application cache through settings

The safest method, which doesn't require any super-user rights or special knowledge, is suitable for beginners.

Instructions:

Open Settings → Applications → Application Management.
Slip on the three dots in the upper right corner and select Sort by size, so you will see the most “gluttonous” programs.
Select an app (like Facebook or TikTok) → Storage → Clear cache.
To clean up the cache of all applications, click Clear the cache of all applications (the option will appear after selecting any application).

How much memory will you have? It depends on your habits.

Annex	Average cache size	Can it be cleaned without risk?
Google Chrome	200-500 MB	Yes (but you will have to re-enter the site)
Instagram	300-800 MB	Yeah (photos reloaded)
MIUI Launcher	50–150 MB	Yeah (interface updated)
WhatsApp	100-300 MB	Yes (messages will persist)

On Redmi 8 Pro, the cache of system applications (for example, com.miui.home) is cleared only through Recovery or ADB - in normal settings, this option is blocked.

Close all background applications

Connect your phone to charge (if charge < 30%)

Backup of important data

Check the space in the memory (should be > 500MB)-->

3. Method 2: Clearing Dalvik cache via Recovery

This method is suitable for power users, as it requires logging into Recovery Mode. Dalvik cache is an optimized file for the Android virtual machine that is sometimes corrupted and causes errors in the application. On Redmi 8 Pro, cleaning it helps solve problems with:

🔄 Loading boots (bootloop).
📱 Self-involved reboots.
⚠️ Errors like “The app has stopped».

Step-by-step:

Turn off the phone.
Press the Power button + Volume up for 10 seconds until the Mi logo appears.
In the Recovery menu, select a language (e.g. English).
Go to Wipe & Reset → Wipe Dalvik Cache.
Confirm the action and wait for the completion (it will take 1-2 minutes).
Reboot your phone with Reboot → Reboot to System.

⚠️ Attention: If after cleaning the Dalvik cache, the phone loads for a long time (up to 10 minutes), this is normal!

This method is also useful before installing custom firmware or updating MIUI via Fastboot.However, do not clean the Dalvik cache more than 1 time every 3 months - this can lead to wear and tear of flash memory.

What is Dalvik Cache and Why Can't It Be Deleted Manually?

Dalvik cache is an optimized version of the applications (.dex files) that the Dalvik/ART virtual machine creates to speed up work. Unlike a regular cache, these files cannot be deleted through the file manager: they are protected by the system and restored automatically when the application is first launched. Forced cleanup through Recovery forces Android to reassemble the cache, which can temporarily slow down the phone, but often solves compatibility problems after updates.

Method 3: Using third-party utilities

If manual cleaning seems difficult, you can use specialized applications.

🧹 SD Maid – deletes residual files and cache, including system files (requires root for full functionality).
🔍 CCleaner is a simple interface, but less effective for deep cleaning.
📊 Files by Google – built-in tool for memory analysis and garbage removal.

Example of working with SD Maid:

Download the app from Google Play.
Launch and provide access to the storage.
Go to the CorpseFinder tab (to remove remnants of remote applications) or SystemCleaner (for cache).
Select files to clean and confirm the action.

The advantages of third-party utilities:

✅ Automatic analysis of junk files.
✅ Ability to clean the cache of all applications in one tap.
✅ Visual statistics of the vacated place.

⚠️ Note: Some applications (such as Clean Master) aggressively delete files, which can cause malfunctions. MIUI. Redmi 8 Pro is better to use. SD Maid or embedded tools.

5. How to Clear the Cache of Google Play Services and Other System Apps

System applications (e.g. com.google.android.gms or com.miui.securitycenter) do not have a "Clear Cache" button on the standard menu, but their cache can be deleted in two ways:

Method 1: ADB (for advanced users)

Connect Redmi 8 Pro to your PC, turn on USB Debugging (Settings → About Phone → MIUI Version – tap 7 times, then return to Additional → For Developers) and execute the command:

adb shell pm clear com.google.android.gms

This will completely reset the data and cache of Google Play Services (you will need to log in to your Google account again).

Method 2: Through Safe Mode

Press the power button, then hold your finger on the Turn off until the Safe Mode window appears.
Confirm the reboot in safe mode.
In Safe Mode, open Settings → Applications and try to clear the cache of system programs (sometimes the option becomes available).

On Redmi 8 Pro, it is especially useful to clear the cache of the following system applications:

📊 com.miui.analytics – collects data for MIUI (It can take up to 100 MB).
🔒 com.android.providers.media – cache of media files (cleaning up will speed up the gallery’s work).
🌐 com.android.chrome – browser cache (even if you don’t use it).

💡

If the apps don't update after clearing the Google Play Store cache, reboot your phone and check your internet connection, sometimes by deleting your Google account and re-signing in.

6. Frequent errors in cleaning the cache and how to avoid them

Many Redmi 8 Pro users make mistakes that instead of speeding up the phone, lead to new problems.

Mistake.	Effects of consequences	How to fix it
Clearing WhatsApp or Telegram cache as data	Loss of chats and media files	Restore backup or use Clear cache rather than Clear data
Deleting Dalvik Cache Without Rebooting	Hanging the phone on the Mi logo	Wait 10-15 minutes or flash your phone over Fastboot
Using “cleaners” with aggressive algorithms	Delete important MIUI system files	Reverse changes via Recovery or reset your phone

Another common problem is that the cache is rapidly reaccumulating, and it's because of:

📱 Frequent use of social networks (TikTok, Instagram).
🌍 Permanent operation of geolocation (for example, in Google Maps or Yandex.Maps).
🔄 Auto-updates of applications in the background.

Decision:

🛠️ Limit the background activity of applications in Settings → Battery → Battery consumption management.
📵 Turn off auto-update apps on Google Play.
🗑️ Clean your browser cache regularly (in Chrome: Settings) → Confidentiality → Clear history).

💡

Cache cleaning is a temporary solution. If the phone brakes even after cleaning, check the CPU boot in Settings → About Phone → System Status. It may be a background process or a virus.

7. Alternative Optimization Methods Redmi 8 Pro

If cleaning the cache did not give the expected result, try:

1. Disabling MIUI animation

This will speed up the transitions between screens:

Activate Developer Mode (as in the ADB method).
Go to Settings → Additional → For developers.
Find options: Window animation scale → No animation. Size of transition animation → No animation. Duration of animation → Disable.

2. Transfer of applications to a memory card

On the Redmi 8 Pro, the microSD slot supports up to 256GB to port apps:

Open the Settings → Applications.
Select an app (e.g. Facebook) → Storage → Change → Memory Map.

3. Reset to factory settings

The last method is if the phone is slowing down a lot. Pre-back up via Settings → Additional → Backup and Reset. Then select Reset → Reset all settings.

After discharge:

🔄 Do not restore backup via Mi Cloud – it will return old cache files.
📱 Install applications gradually, checking performance.
🔒 Turn off the autoload of unnecessary programs to Security → Auto-start.
