How to Clear Cache in Xiaomi Phone Browser: A Detailed Guide for All Models

Why cleaning up your browser cache on Xiaomi is not a luxury, but a necessity

Have you noticed that Xiaomi's favorite smartphone is slowing down when you open web pages, and your browser is hanging for half a minute? Or suddenly you stop saving passwords in Google Chrome, when everything used to work? 90% of these problems are caused by a crowded browser cache. These are temporary files that accumulate with every load of sites: pictures, scripts, styles, cookies. On MIUI, the cache can take up to 1-2 GB of memory, even if you do not consider yourself an active user of the Internet.

The feature of MIUI firmware (including versions 12, 13 and 14) is that it aggressively caches data to speed up repeat visits to sites, but over time this leads to the opposite effect: the browser begins to “choke” from excess garbage. For example, on Redmi Note 11 or POCO X5, users often experience an error “Insufficient memory” precisely because of an uncleaned cache.

In this article, we will discuss:

• 🔍 How to check how much cache has accumulated in your browser
• 🧹 Step-by-step instructions for Mi Browser, Chrome, Firefox and other popular browsers
• ⚡ What to do if cleaning the cache did not help speed up the work
• ⚠️ What data can be lost during cleaning (and how to avoid it)

How to check the amount of cache in the browser on Xiaomi

Before you start cleaning, you should assess the scale of the problem. On MIUI, there are two ways to know how much space the browser cache takes up: through the settings of the browser itself and through the system menu "Storage".

In Mi Browser (the standard Xiaomi browser), the path is this: open the application → tap on three dots in the lower right corner → Settings → Privacy → Clear the data. Here you will see the sections "Cache" and "Cookies and Site Data". On POCO F4, for example, the cache can reach 800 MB after a month of active use.

Google Chrome has a similar algorithm: three dots at the top → History → Clear the data. The system will show the exact amount of cached files. Interesting fact: Xiaomi with MIUI 14 Chrome often caches data more aggressively than on pure Android, due to the manufacturer's optimizations.

System-based verification (works for all browsers): open Settings → Storage → Storage Analysis. Here, select the Apps section and find your browser. On Xiaomi 13 Pro with MIUI 14, this method shows even hidden cache files that are not displayed in the browser settings.

💡

If the cache is over 1 GB and you haven't cleaned it for more than a month, it's critical, and it's recommended that you delete the cache and reboot your phone to optimize your work.

Step-by-step: how to clear the cache in Mi Browser on Xiaomi

Mi Browser is a standard app on all Xiaomi, Redmi and POCO smartphones. Its cache clears differently than in Chrome, so let's break it down separately. Importantly, on MIUI 14, the interface has changed slightly from MIUI 12, but the logic has remained the same.

Instructions for MIUI 13/14:

1. Open Mi Browser.
2. Slip on the icon three dots in the lower right corner (on some models, for example, Redmi 10C, it is located at the top).
3. Select Settings → Confidentiality.
4. Press Clear Data.
5. Put the boxes next to you: 🗑️ Cash (required) 🍪 Cookies and website data (optional, but recommended)

Clean up

On MIUI 12 and older, the path is a little different: Settings → Additional → Privacy → Clear the data. If you have a POCO M4 Pro or another model with a POCO Launcher shell, the menu looks different, but the essence remains the same.

Save important tabs in bookmarks|Remember passwords from websites (they can be reset)|Close all active tabs|Connect your phone to charge (in case of long cleaning)-->

Once cleaned, the browser can run slower the first time you open a site — that's okay. It caches data again. On Xiaomi 12T with MIUI 13, for example, after clearing 1.3 GB of cache, page loading speeds increased by 40% in a day.

⚠️ Note: If you clear cookies, you will be kicked out of all accounts on the sites (social networks, mail, banks.

Cleaning up cache in Google Chrome on Xiaomi phones

Google Chrome is the most popular browser on Xiaomi, but its cache doesn't clear as obviously as it does in Mi Browser.The main feature: on MIUI, Chrome often runs in the background even after closing, so it needs to be completely stopped before cleaning.

Step-by-step:

1. Close Chrome through the latest app menu (swipe up).
2. Open Settings → Applications → Application Management.
3. Find Chrome in the list and tap it.
4. Press Forced Stop (this is important for MIUI 14, otherwise the cache will not clear completely).
5. Return to Chrome, open the menu (three dots) → History → Clear the data.
6. Select the time range (recommended "All the time").
7. Check the boxes: 🗃️ Cached images and files 🍪 Cookies and website data (optional)

Clear the data

On the Redmi Note 12 Pro+ with MIUI 14, up to 1.5GB of memory is freed up after this procedure, but here’s the caveat: if you sync with a Google account, some of the data (such as history) will recover after the reboot.

For deep cleaning (if Chrome is still slowing down):

• 🔄 Restart your phone after cleaning the cache.
• 🛠️ In Chrome settings, turn off Traffic Savings (it may conflict with caching on the MIUI).
• 📥 Update Chrome to the latest version via Google Play.

Clearing cache in other browsers: Firefox, Opera, Edge

If you use alternative browsers, the cache clearing process will be different, with Firefox (by protecting privacy) and Opera (by using the built-in VPN) being particularly popular on Xiaomi.

Mozilla Firefox:

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

On POCO X3 Pro, Firefox caches data more sparingly than Chrome, but can still accumulate up to 500MB per month.

Opera:

1. Menu (O) → Settings → Privacy.
2. Choose Clear Visit Data.
3. Mark Cached Images and Files.

Opera has a Quick Cleanup feature (a bin icon at the bottom of the screen), but it only removes the history, not the cache.

Microsoft Edge:

1. Menu (three dots) → History → Clear browser data.
2. Select Cache Data and Files.

On Xiaomi, the 11T Edge is often used to work with office documents. Its cache rarely exceeds 300 MB, but can conflict with the Mi Browser when used simultaneously.

⚠️ Attention: Firefox on MIUI 14 Sometimes a bug works: after cleaning the cache, the browser stops opening some sites. The solution is to restart the phone or reset the network settings in Settings. → SIM-maps and mobile networks → Resetting network settings.

What to do if cleaning the cache did not help to speed up the browser

And sometimes, after the cache is cleared, the browser on Xiaomi keeps slowing down, which means that the problem is deeper, POCO and other lines:

• 🔄 Reset the phone. MIUI after cleaning the cache, a restart is required to release RAM.
• 🗑️ Clear the system cache: Settings → Warehouse → Clear the cache (not to be confused with the browser cache!).
• 🛠️ Turn off optimization. MIUI for the browser: Open Settings → Annexes → Application management. Select the browser → Battery → Battery optimization. Install "No restrictions".
• 📱 If Xiaomi has less than 10% of the memory left, the system starts to slow down.
• 🔒 Turn it off. VPN Or proxy, if you use it, they might conflict with caching.
• ⏰ Autocleaning on schedule: In Security App go to Settings → Autoclean. Turn on the function and set a schedule (e.g. once a week). minus: autocleaning can remove not only cache, but also useful data.
• 📱 Third-party applications (e.g. CCleaner or Files by Google) can clear the cache of all browsers simultaneously.
