How to completely clear the cache on Xiaomi Redmi Note 10S: from applications to system files

Xiaomi Redmi Note 10S is a popular smartphone with a powerful chipset MediaTek Helio G95, but even it eventually begins to “slow down”. The main reason is crowded cache. In this article, we will discuss how to clean it properly to return the device performance without losing data.

Cache is a temporary file that creates applications and a system to speed things up, but when too many of them accumulate, they take up precious space on the internal drive and slow down the Redmi Note 10S. Cache cleanup helps solve problems with lags, overheating and sudden crashes of applications.

It’s important to understand that deleting cache does not delete your personal data (photos, contacts, messages), but may require re-entering some accounts. We’ll look at all the available methods, from manual cleaning to hidden MIUI features.

What is the cache and why should it be cleaned on the Redmi Note 10S?

Cash is divided into three types:

• 📱 App cache – temporary data that creates instant messengers, browsers and games to quickly load content.
• 🖥️ System cache – files that generate MIUI to optimize the interface.
• 🌐 Browser cache – saved pages, cookies and history in Chrome, Mi Browser or other browsers.

On the Redmi Note 10S with 64/128GB of storage, the cache can take up to 5-10GB — critical if you don’t have much space. For example, after a year of uncleaned use, WhatsApp cache can weigh 1-2GB and Instagram can weigh up to 500MB.

Signs that it is time to clean the cache:

• 🐢 The smartphone began to “hang” when opening applications.
• 🔥 The device overheats for no apparent reason.
• 📉 Your memory is full, even though you haven’t downloaded anything.
• 🔄 Applications are closed spontaneously.

⚠️ Warning: Don’t confuse cache with app data! Cache cleaning is safe, and deleting app data (e.g. Telegram or Viber) will result in the loss of chats and media files.

Method 1: Clearing the cache of individual applications

The most targeted method is to remove the cache only for the programs that occupy the most space, and it will not affect the performance of other applications.

Instructions:

1. Open Settings → Applications → Application Management.
2. Select the app you want (like Facebook or YouTube).
3. Press Warehouse. → Clear the cache.

For convenience, sort the applications by cache size:

1. In Application Management, tap three dots in the upper right corner.
2. Select Sort. → By size.
3. Clear the cache from applications that are larger than 100-200 MB.

Example: Google Play Services cache can weigh up to 1GB, but cleaning it won’t hurt the system, but Mi Video or Mi Music cache is best avoided if you watch videos or listen to music offline.

⚠️ Attention: After cleaning the cache of Google Play Store may need to restart the smartphone, otherwise the application will issue errors when updating programs.

Method 2: Mass cleaning the cache of all applications

If you don’t have time to clean each application separately, use the built-in MIUI function for mass cleaning.This will save time, but will remove the cache of all programs, including system ones.

Step-by-step:

1. Go to Settings. → Memory.
2. Click Clean in the Cash section of the applications.
3. Confirm the action by tapping OK.

Alternative path (if the first one fails):

1. Open the settings → About the phone → Memory.
2. Select the Cache Data and confirm the cleanup.

💡

After mass clearing the cache, restart the Redmi Note 10S – this will help the system recover the necessary temporary files faster.

Method 3: Clearing the browser cache (Chrome, Mi Browser, Firefox)

Browsers are the main cache eaters. For example, Google Chrome can accumulate up to 1-2 GB of temporary files if it is not cleaned for months. Consider how to remove cache in popular browsers on the Redmi Note 10S.

For Google Chrome:

1. Open your browser and tap three dots in the upper right corner.
2. Choose a History. → Clear the data.
3. Check boxes next to Cookies and Site Data and Cache Images and Files.
4. Press Clear Data.

For Mi Browser:

1. Launch your browser and go to the menu → Settings.
2. Select Confidentiality → Clearing personal data.
3. Mark Cash and confirm the cleanup.

For Mozilla Firefox:

1. Open the menu (three points) → Settings.
2. Go to Deletion of Personal Data.
3. Select Cash and click Delete Data.

⚠️ Note: If you use Mi Browser in Easy mode (this is indicated by the zipper icon in the address bar), the cache is cleared automatically when you close the browser.

Method 4: Cleaning the system cache with Recovery Mode

This method removes deep system files that are not available through standard settings. This is suitable if the Redmi Note 10S is severely slowing down or emits errors. Use it only if other methods did not help - improper actions in Recovery can lead to a reset.

Instructions:

1. Turn off your smartphone.
2. Press the Power + Volume buttons up at the same time and hold for 10-15 seconds until the Mi logo appears.
3. In the Recovery menu, select a language (e.g. English).
4. Go to Wipe & Reset → Wipe Cache.
5. Confirm the action and wait for the process to be completed.
6. Select Reboot → Reboot to System to reboot.

What's removed:

• 🗃️ Temporary update files MIUI.
• 🔄 Cache of system cores and drivers.
• 📂 Error logs and debugging data.

💡

Cleaning the system cache through Recovery does not delete your data, but resets some system settings (e.g., regional settings).

Method 5: Automatically clean the cache with Security App

Xiaomi is building a Security utility into MIUI that can automatically clean the cache on a schedule, which is handy if you don't want to do it manually.

How to set up:

1. Open the Security app (the shield icon).
2. Go to the Cleanup tab.
3. Click Deep Clean and select Cash applications.
4. Activate the Auto Clean option and set a schedule (e.g. once a week).

Advantages of the method:

• ⏰ Don’t forget to clean – everything is done automatically.
• 🛡️ Security analyzes which files can be safely deleted.
• 📊 It shows how much space is freed up after each cleaning.

Disadvantages:

• ⚠️ Sometimes it removes the cache of useful applications (such as Google Maps), which makes them load longer.
• 🔄 It may conflict with other SEOs (e.g. CCleaner).

What to do if after cleaning the cache problems remain

If the Redmi Note 10S continues to brake even after cleaning the cache, check the following points:

1. Free disk space

The minimum storage capacity for stable operation is 10-15% of the total. If you have 128 GB, at least 12-15 GB should be free. Check Settings → Memory.

2. Background activity of applications

Some programs (like Facebook or TikTok) continue to run in the background and clog up RAM.

1. Go to Settings → Applications → Application Management.
2. Select the problem application → Battery → Background Limitation.

3. MIUI updates

Outdated firmware can cause lags. Check the relevance of the version:

1. Open Settings → About the phone → System update.
2. If you have an update, install it (preferably via Wi-Fi).

4. Viruses and malware

Some viruses are cache-masked and consume resources.

1. Open Security. → Antivirus.
2. Run a deep scan.

💡

If the smartphone began to brake after updating MIUI, try to reset the settings to factory (but pre-return!).
