Cache Cleanup on Xiaomi Redmi Note 8: A Complete Guide to Speeding Up Your Phone

Your Xiaomi Redmi Note 8 is slowing down, apps are loading for a long time, and memory is constantly filled with unknowns? The reason most often lies in clogged cache — temporary files that accumulate over time. Clearing the cache will not only free up space on the device, but can also significantly speed up its operation. In this article, we will analyze all the ways to clean the cache on the Redmi Note 8, from standard MIUI tools to hidden functions and third-party applications.

It is important to understand that there are two types of cache: application cache (temporary program files) and system cache (operating system files). Their cleaning has different consequences: deleting the application cache is usually safe, but with the system cache you need to be careful. We will explain in detail how to clean each type without damaging the phone.

If you’ve never cleared your Redmi Note 8 cache, be prepared to get 1 to 5GB of storage after the procedure, especially for users who are actively using instant messengers, social networks and streaming services.

Why cache accumulates and what is it dangerous

Cache is a temporary file that is created by apps and systems to make things faster, for example, when you open Instagram, the app saves thumbnails of photos so that it can show them faster the next time it runs, and over time, these files accumulate, taking up more space.

The main reasons for filling the cache on Redmi Note 8:

• 📱 Frequent use of social networks (Facebook, TikTok, VKontakte)
• 🎮 Games with high resource consumption (PUBG Mobile, Genshin Impact)
• 📺 Streaming video (YouTube, Netflix, Twitch)
• 🗺️ Navigation applications (Google Maps, Yandex.Maps)
• 📁 Automatic updates to applications and systems

What is dangerous is a crowded cache:

• ⚠️ Slowing down the phone – apps start to “hang"
• ⚠️ Overheating of the device due to increased load on the processor
• ⚠️ Fast battery discharge – the system spends resources on processing unnecessary files
• ⚠️ Errors in the operation of applications, especially if the cache is damaged

On the Redmi Note 8 with its 64 or 128 GB of storage, the cache can take up to 10-15% of the total, which is especially critical if you’re using a budget version with 64 GB, where every gigabyte counts.

How to Clear the Cache of Individual Applications

The safest way is to clean the cache for specific applications, and this will not delete your data (photos, messages, settings), but only temporary files.

Instructions for cleaning the app cache on Redmi Note 8:

1. Open the settings (cog icon)
2. Go to the Applications section → Application management
3. Select the desired app from the list (such as WhatsApp or Chrome)
4. Click Warehouse → Clear the cache

For convenience, you can sort applications by cache size:

1. In the Application Management section, click on three dots in the upper right corner
2. Select Sort by Size
3. Now at the top of the list will be the applications with the largest cache

Some apps can weigh particularly heavily. Here's the top-5 "Cache eaters on Redmi Note 8:

⚠️ Note: Do not clear the cache for system applications (e.g. com.android.systemui or com.miui.home) unless absolutely necessary. MIUI.

Mass cleaning of cache of all applications

If you clean each application’s cache separately for too long, you can use the mass-cleaning feature, which will save time, but beware – some applications may then run slower on the first run.

Method 1: Through storage settings

1. Open the Settings → Storage
2. Click Clean in the "Cash" section
3. Confirm the action by clicking Clean in the window that appears

Method 2: Using the Security App

1. Open the Security app (shield icon)
2. Go to the Cleanup tab.
3. Click Deep Cleaning → Cash
4. Select all applications or check out unnecessary ones
5. Click Clean (bottom of the screen)

💡

After mass cleaning of the cache, restart the phone - this will help the system correctly recalculate the free space and avoid possible glitches.

On the Redmi Note 8 with active use, mass cache cleaning usually frees up from 1 to 3 GB. However, the effect is temporary - after 1-2 weeks, the cache will begin to accumulate again.

Cleaning system cache (Dalvik-cache and others)

System cache is a temporary file that Android creates to speed up work, and cleaning it can help if the phone is slowing down, but it's a more risky procedure than cleaning the app cache.

On the Xiaomi Redmi Note 8, the system cache can only be cleaned through Recovery Mode. Incorrect actions in this mode can cause the phone to reset to factory settings!

Instructions for cleaning the system cache:

1. Turn off the phone.
2. Press the Power + Volume buttons up at the same time and hold for 10-15 seconds
3. When the Mi logo appears, release the buttons and you will be taken to Recovery Mode.
4. Use volume buttons for navigation and power button for selection
5. Select the Wipe & Reset option → Wipe Cache
6. Confirm the action by choosing Yes
7. After you complete the process, select Reboot → Reboot to System.

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

Once the system cache is cleared, the first launch of the phone may take longer — that's OK.

Using third-party applications to clean up the cache

If standard MIUI tools don't suit you, you can use third-party utilities, which often offer more flexible settings and additional features, such as cleaning residual files after deleting applications.

Top.-3 Apps to clean up cache on Redmi Note 8:

• 🧹 CCleaner – classic garbage cleaner with garbage analysis and optimization
• 🔍 SD Maid is a powerful tool for finding and removing unnecessary files
• 🛡️ Files by Google – a simple application from Google with the function of cleaning cache

Instructions for using CCleaner:

1. Install the app from Google Play
2. Open it and provide the necessary permissions.
3. Go to the Cleanup tab.
4. Click Analysis and wait for the scan to be completed.
5. In the "App Cache" section, select what to clean.
6. Click Clean (bottom of the screen)

💡

The cache cleaning app may request access to personal data, read carefully what permissions you give, and use only proven high-rated utilities.

Advantages of third-party cleaners:

• 🔹 More in-depth analysis of junk files
• 🔹 Possibility of setting up automatic cleaning
• 🔹 Additional features (battery optimization, autoboot management)

Disadvantages:

• ⚠️ Risk of installing malware (download only from the official store)
• ⚠️ Some apps show the "junk" that the system actually needs
• ⚠️ Can slow down your phone when scanning

Automatic Cache Cleanup: Scheduled Setup

To avoid manually clearing the cache, you can set up automatic cleaning. On the Redmi Note 8, this is done through the Security app.

Instructions for setting up automatic cleaning:

1. Open the Security app
2. Go to the Cleanup tab.
3. Click on the gear icon in the upper right corner
4. Select Auto Cleanup
5. Activate the switch at the top of the screen
6. Set up a schedule (daily, weekly or manually)
7. Choose which file types to clean (cache, temporary files, empty folders)

Recommended settings for Redmi Note 8:

• 🔄 Cleaning frequency: 1 time per week (more often not necessary, less often inefficient)
• 🕒 Cleaning time: at night (when the phone is not used)
• 📁 File types: application cache and residual files (system cache is better not to touch)

Auto-cleaning will help keep your phone in good condition, but remember to check the storage manually from time to time – some files may not fall under automatic cleaning.

What to do if cleaning the cache does not help

If the phone still brakes after cleaning the cache, the problem could be deeper.

• 🔄 Reboot your phone – sometimes it helps even better than cleaning the cache
• 🗑️ Remove unnecessary apps – especially those that haven’t been used for a long time
• 🔍 Check for viruses – some malware creates a lot of junk files
• 📱 Update the firmware - in new versions MIUI Often optimize the work with memory
• 🔧 Make a reset to factory settings - an extreme measure if nothing helps

If the problem is in a particular app, try:

1. Clear its data (not just cache!) in Settings → Apps
2. Reinstall the application
3. View reviews on Google Play – a massive problem

The Redmi Note 8 can eventually lose performance due to wear and tear on flash memory. If the phone is in use for more than 2-3 years, cleaning the cache will give a temporary effect, in which case you should think about replacing the device or installing a light firmware.
