How to disable the opening of the browser on Xiaomi: a complete guide for all models

Why Xiaomi Browser Opens on Its Own and How to Fix It

Owners of Xiaomi, Redmi and POCO smartphones often face an annoying problem: the Mi Browser or Google Chrome browser suddenly launches without a user command. This is due to aggressive MIUI optimization, which tries to “help” the user, but in practice only interferes. The reasons for autorun can be different from system notifications to hidden features of advertising services.

In this article, we’ll look at all the possible ways to disable browser autostart on Xiaomi devices, including hidden MIUI settings, application permissions, and even radical methods for power users. The instructions are relevant for all modern models, from the budget Redmi Note 12 to Xiaomi 14 Ultra flagships running MIUI 12-14 and Android 10-14.

It's important to understand that the problem isn't always about viruses or system failures, but more often than not, it's about planned MIUI behavior that can be adjusted without resetting or flashing it, and then starting with the simplest methods and moving on to more complex solutions.

Method 1: Disabling Autostart in Application Settings

The most obvious and safe method is to block the browser’s background activity through the app menu, which works for both browsers: Mi Browser (embedded) and Google Chrome (installed separately).

Instructions:

1. Open Settings → Applications → Application Management
2. Find the browser (or Chrome) in the list and tap it.
3. Go to the Permissions section
4. Turn off the Autostart switch
5. Go back and select Battery → Background Limitation → Limit

After these actions, the browser will not be able to run independently through system events, but this method does not always work 100%, since some MIUI processes may ignore these limitations.

💡

If after disabling autorun the browser still opens when connecting to Wi-Fi, check the settings of the router – some models send push notifications, which MIUI interprets as a command to open the browser.

Method 2: Block notifications from the browser

Often the browser is launched due to push notifications that come from websites or system services, these notifications may be hidden and not displayed in the curtain, but still initiate the opening of the browser.

• 🔔 Go to Settings. → Notifications and status bar → Management of notifications
• 📱 Find the browser or Chrome in the list of applications
• 🔕 Disable all switches in Allow notifications section
• 🌐 In the browser itself (on the menu) ⋮ → Settings → Site Notifications Block All Permissions to Show Notifications

1. Go to Settings → Memory → Cleanup
2. Slap the icon. ⚙️ top-right
3. Turn off the option to show cleaning notifications

Method 3: Disabling MIUI's "Smart Functions"

MIUI has several hidden features that can run a browser without your knowledge, the most problematic of which are:

1. Smart Assistant – analyzes your behavior and “suggests” to open the browser under certain conditions (for example, when you look at the lock screen for a long time)
2. Quick Links – Creates desktop shortcuts for frequently visited sites that can run automatically
3. Charging optimization – shows banner ads when connecting charging that open in the browser

To disable these functions:

1. Go to Settings → Special features → Smart assistant and turn off all options
2. In Settings → Desktop disable Quick Links and Recommendations
3. In Settings → Battery → Optimization of charging turn off the display of advertising

Disable Smart Assistant in Special Opportunities |

Remove Quick Links from the Desktop |

Turn off ads when charging |

Check the battery optimization settings-->

These actions will significantly reduce unwanted browser launches, especially on new devices with MIUI 13/14, where smart features are most aggressive.

Method 4: Using ADB for deep shutdown (for experienced)

If standard methods do not help, you can use them. ADB-This requires connecting the phone to a computer and basic command line knowledge.

Instructions:

1. Install Platform Tools on your computer
2. Enable USB Debugging in Settings → About Phone → MIUI Version (Tap 7 times) → More → For Developers
3. Connect your phone to your PC and execute the command: adb shell pm disable-user --user 0 com.android.browser For Chrome use: adb shell pm disable-user --user 0 com.android.chrome

These commands will completely disable browsers at the system level. To bring them back, use:

adb shell pm enable com.android.browser

⚠️ Note: Disabling system applications through ADB This can lead to unstable operation of some functions. MIUI, Especially if you use Xiaomi’s branded services (such as Mi Cloud or Mi Video).

Method 5: Reset browser settings and clear cache

Sometimes, when a browser is opened spontaneously, it's caused by corrupted cache data or conflicting extensions, and a complete cleanup can solve the problem:

1. Go to Settings → Applications → Application Management → Browser
2. Select Warehouse → Clear cache and Clear data
3. For Chrome, go to your browser settings and do: Reset settings (⋮ → Settings → Resetting settings) Removing all saved passwords and autocomplete Disable sync with Google account

Once cleaned, restart the device. If the problem was caused by corrupted data, the browser will stop opening on its own, a method that is especially effective after MIUI updates when old data conflicts with a new version of the system.

Additional measures: what to do if nothing helps
