How to completely delete cookies on Xiaomi smartphones: instructions for all models

Cookies are small files that websites store on your device to store session data, login and personalized settings. On Xiaomi smartphones running MIUI, these files can accumulate in browsers (Chrome, MIUI Browser, Firefox) and system applications, taking up space and potentially creating privacy risks. If you notice that sites are slower, advertising has become too “personalized” or just want to clear the digital footprint – this article will help you figure out how to properly remove cookies on any Xiaomi model (from Redmi Note 10 to 14 Xiaomi Ultra).

Unlike computers where cookies are stored in one place, on Android devices they are distributed between browsers, application cache and system data. We’ll look at all the current cleaning methods, from manual removal through browser settings to the use of hidden features MIUI, which are not written in the official documentation. We will pay special attention to the nuances for new versions of Android 13/14 and the proprietary shell HyperOS, where the location of some menus has changed.

Why you should delete cookies on Xiaomi and when to do it

Cookies are not harmful in themselves – they speed up the loading of frequently visited sites and save your logins. However, there are several reasons to clean them regularly:

• 🔒 Privacy: Cookies may contain information about your preferences, location, and even bank cards (if you have stored them on the sites), which becomes vulnerable when leaked.
• 🚀 Performance: Accumulated cookies slow down browsers. On Xiaomi with 64-128 GB of memory, this is less critical, but on budget models (Redmi A2, Poco C50), the difference is noticeable.
• 🎯 Advertising: Cookies are used for targeted advertising. Once cleaned, you will see fewer intrusive banners.
• 🔄 Site errors: Sometimes cookies conflict with updated versions of sites, causing crashes (for example, endless reloading of pages).

When it is necessary to delete cookies:

• ✅ Before selling or transferring a phone to another person.
• ✅ If you notice that the browser has become "hang" when you open tabs.
• ✅ After visiting questionable sites (especially if pop-ups appear).
• ✅ When changing your account on websites (for example, logging out of one AliExpress profile and logging in to another).

⚠️ Warning: Deleting cookies will automatically log out of all accounts on the sites (social networks, email, banks).

Method 1: Delete cookies in Google Chrome

Google Chrome is the most popular browser on Xiaomi, and it clears cookies separately from system data. The instructions are relevant for Chrome 120+ versions (check the updates in the Play Market).

Steps for cleaning:

1. Open Chrome and tap on the three-point menu (⋮) top-right.
2. Choose a History. → Clear the data.
3. Tab Basic: tick next to Cookies and Site Data and Cache Images and Files.
4. In the drop-down menu, select Time Range For All Time (if you want to delete everything) or Last 24 hours (for partial cleaning).
5. Click Delete Data and confirm the action.

For advanced users: if you need to delete cookies for only one site, go to Settings → Privacy → Site settings → Cookies and select the desired domain in the list.

Close all important tabs (the data will not be saved)

Save passwords from autocomplete (if you use)

Check that there are no unpaid payments in Chrome

Turn off sync with Google (unless you want to clear your data on other devices)-->

⚠️ Warning: If you use Incognito mode in Chrome, the cookies are deleted automatically after you close the tabs. But this is not the case with the normal mode!

Method 2: Clearing cookies in MIUI Browser (standard Xiaomi browser)

The branded MIUI Browser (formerly Mi Browser) is installed by default on all Xiaomi smartphones. Here, cookies are cleared differently than in Chrome, and the menu may differ depending on the version of MIUI/HyperOS.

Instructions for MIUI 14 and HyperOS:

1. Open the MIUI Browser and tap the profile icon (👤) in the bottom menu.
2. Go to Settings. → Confidentiality.
3. Select Clear browser data.
4. Check boxes: Cookies and data of Cash sites (optional, to speed up work)

Clean up

In older versions of MIUI (up to 12), the path might look like this: Settings → Additional → Privacy → Clear the data. If you don’t find a menu, update your browser through the Play Market.

💡

If after cleaning cookies in MIUI Browser sites began to open more slowly, try to disable the option "Saving traffic" in the browser settings - it may conflict with new data.

Method 3: Delete cookies through Android settings (system method)

This is a good way to delete all cookies and cache for all browsers and applications at once, and it is more radical but effective – especially if you don’t remember which browser has stored the data that you don’t need.

Step-by-step:

1. Open the phone settings (cog icon).
2. Go to the Apps → Application management.
3. Slip on the three-point menu (⋮) and select Show System (to see all browsers).
4. Find in the list of Chrome, MIUI Browser or other browser, which cookies you want to delete.
5. Select Warehouse → Clear Data → Clear Cache and Clear All Data (the second option will delete both cookies and saved passwords!).

Important: Xiaomi with Android 13+ may need to restart the phone after this step to make the changes take effect. If the browser becomes unstable after cleaning, reinstall it through the Play Market.

To completely clear system cookies (e.g. from Mi Account or Xiaomi Cloud applications):

1. Go to Settings → Memory → Cleanup.
2. Choose Deep Cleaning and wait for analysis.
3. In the results, find the System Cache section and clean it.

How to clear cookies through Files by Google:

1. Install the app from the Play Market (if it is not available by default).
2. Open it and go to the Cleanup tab.
3. Select the Garbage Files and wait for the scan.
4. In the results, find the browser data or cookies section and mark them.
5. Click Clear XXMB and confirm.

The advantage of this method is visualization: you will see how much space cookies take up (sometimes up to 500 MB+ on a actively used phone).

Method 5: Reset browser settings (nuclear method)

If cookies are deleted but returned after rebooting, or the browser has become incorrect (for example, MIUI Browser is constantly dyeing), resetting the settings to factory will help, this will delete all data, including:

• Saved passwords
• Bookmarks
• History of visits
• Synchronization settings

How to reset Google Chrome:

1. Open Settings → Applications → Application Management → Chrome.
2. Slip the storage → Space management.
3. Choose Clear all data (not to be confused with Clear cache!).
4. Confirm the action. The browser will return to "as after installation."

For MIUI Browser:

1. Go to Settings → Applications → MIUI Browser → Storage.
2. Click Reset (in some versions - Delete data).

⚠️ Warning: After resetting, the browser may request re-entering of Google account data (if synced). If you forget the password, restore it in advance on another device.

💡

Resetting your browser is a last resort. Before you do that, export your bookmarks through the Bookmarks → Export menu (in Chrome) or sync with your Xiaomi/Google account.

Additional tips: how to reduce the accumulation of cookies on Xiaomi

To clear cookies less often, set your phone in advance:

• 🔄 Turn off auto-sign in: In your browser settings (Settings → Passwords), delete saved logins for important sites (banks, mail).
• 🛡️ Use VPN: Applications like Xiaomi VPN (embedded in MIUI) or ProtonVPN mask your IP, making it harder to track through cookies.
• 🌐 Incognito Mode: In Chrome and MIUI Browser, cookies in this mode are deleted automatically after tabs are closed.
• 🚫 Cookie Blocker: Install the uBlock Origin extension (available for Firefox on Android) – it blocks the trackers that create cookies.

For HyperOS users: The new shell features Confidential Mode (similar to Sandbox), which isolates application cookies.

1. Go to Settings → Privacy → Confidential mode.
2. Add your browser to the list of isolated applications.
3. Cookies will now be deleted when you leave the mode.

If you use public Wi-Fi frequently (in cafes, airports), set up automatic cookie clearing via MacroDroid or Tasker, which allows you to create rules like: “When connecting to a new network → Clear cookies in Chrome”.

Frequent errors in deleting cookies and how to avoid them

Even experienced users of Xiaomi sometimes face problems when clearing cookies. Consider the typical errors and solutions:

Another common problem is that after clearing cookies, some sites (e.g. banking) require re-authorization via SMS. This is normal – this is how two-factor authentication works. Never save bank passwords in your browser – use official applications (Sberbank Online, Tinkoff, etc.).

💡

If after all the manipulations cookies still do not delete, check if there are any Magisk or other modifications installed on the phone, they can block changes in system files, in which case only a complete reset of the phone to the factory settings will help.
