Is your Xiaomi slowing down and your browser slowing down when you open pages? Most often it's cache-clogged, a huge history of visits, and accumulated cookies, POCO Or Mi not only frees up memory, but also protects your data from leaks. In this article, we'll look at everything from basic cleaning to resetting browser settings to factory-based storage.
Xiaomi phones often come with a pre-installed Mi Browser (formerly the Miui Browser) that is integrated deeper than third-party apps, which means that standard cleaning methods through Android settings may not work. We'll show you how to clean both the built-in browser and popular alternatives like Google Chrome or Mozilla Firefox.
Before you start, check how much space your browser takes up:
- 📱 Open the Settings. → Annexes → Application management
- 🔍 Find your browser in the list and see the Memory section"
- 📊 If the cache volume exceeds 500 MB, it is time to act!
On Xiaomi phones with MIUI 14+ Built-in browser can take up to 1.5 GB of memory when used actively – this is a record among Android smartphones.
1. Clearing the cache and browser data through the settings MIUI
The fastest way to free up space is to delete temporary files directly through system settings, which works for all browsers, including Mi Browser, Chrome, and Firefox.
Instructions:
- ⚙️ Go to Settings. → Annexes → Application management
- 🔎 In the search bar, enter the browser name (for example, "Browser" or "Chrome")

- 🚫 To completely reset, click “Clear Data” – this will delete all saved passwords, history and browser settings!

⚠️ Note: If you use Mi Browser with a Xiaomi account binding, clearing the data won’t remove the bookmarks synced to the cloud!
2. Manual cleaning of history and cookies in Mi Browser
Mi Browser (built-in browser on the Xiaomi/Redmi/POCO) has its own cleaning menu where you can selectively delete history, cookies or download files without completely resetting.
Step-by-step:
- 🌐 Open the Mi Browser and tap on three points (⋮) lower-right
- 📋 Select "History" (watch icon)
- 🗑️ Click "Clear browser data" at the bottom of the screen

- 🔄 Select the period: "All the time" for complete cleaning
- 🚀 Press "Clean" and confirm.

If you only need to delete the story for the last hour or day, select the appropriate period in the cleanup menu, which is useful if you accidentally closed an important tab and want to restore it through the story.

|---|---|---|
| History of visits | List of visited sites for the selected period | ❌ Not (unless synced with your account) |
| Cookies | Authorization data, online shopping carts, site settings | ✅ Yes (on re-entry to the site) |
| Cash files | Images, scripts, styles of sites (take up the most space) | ✅ Yes (websites will load more slowly when they first open) |
| Passwords. | Saved logins/passwords for websites | ❌ Not (unless synchronized with Mi) Cloud/Google) |
