What to do if Xiaomi browser is dumbed down: a complete guide to eliminating lags

The Mi Browser is a standard app on Xiaomi, Redmi and POCO smartphones that is often criticized for slow work. Users experience hanging pages when scrolling, long content loading or sudden tab closures. The reasons may lie in both the browser settings and the device’s system limitations. In this article, we will discuss all possible ways to eliminate brakes, from basic to advanced, including alternative solutions for those who are willing to abandon the standard browser.

It's important to understand that the problem isn't always directly related to Mi Browser. Often, it's the overloaded memory of the device, conflicting background processes, or even viruses in the cache. We'll analyze each scenario and suggest proven optimization methods. If you've tried to reset your browser settings, but it didn't help, don't rush to delete it. It might be enough to clear the Website Data or turn off the energy-saving mode for the application.

This article is relevant for all Xiaomi models based on MIUI 12-14 (including HyperOS), as well as for POCO and Redmi devices with Mi Browser preinstalled. If you have a different version of the firmware, check the compatibility of methods in the relevant sections.

1. Basic actions: reboot and clean the cache

Start with the simplest steps that often solve the problem without deep settings. Rebooting your smartphone closes all background processes that may conflict with your browser. After restarting the system, check if the lags are still there. If so, move on to clearing the cache.

To clear the Mi Browser cache:

1. Open Settings → Applications → Application Management.
2. Find Mi Browser on the list and tap it.
3. Select Warehouse. → Clear the cache.
4. To completely reset, click Clear Data (be aware that this will delete the history and saved passwords).

If after cleaning the browser began to work faster, but after a while the lags returned - the problem lies in the accumulation of temporary files. In this case, regular cleaning of the cache (every 1-2 weeks) or the use of third-party utilities like CCleaner (with caution!) will help.

2. Optimization of browser settings

Mi Browser has hidden settings that affect performance, such as preloading pages speeds up link opening, but consumes additional resources to disable it:

1. Open your browser and tap on three points (⋮) top-right.
2. Go to Settings. → Additionally.
3. Turn off the page preload option.

Also check the following parameters:

• 🔄 Automatic page updates: turn off in Settings → Content if the sites are updated without your involvement.
• 📱 Traffic savings: include in Settings → Networking – this will reduce the amount of data you download, but may worsen the display of some elements.
• 🔒 Ad Blocking: Activate in Settings → Privacy to reduce the number of scripts downloaded.

If the browser still slows down, try resetting to factory settings:

1. In the browser menu, select Settings → Additional → Resetting.
2. Confirm the action and restart the application.

💡

If after resetting the browser began to work faster, but you lack functionality (for example, synchronization with a Xiaomi account), try turning on options one by one to identify the one that causes the lags.

3. background processes and autoboot check

One of the main reasons for the brakes is the restriction of background activity by MIUI, which can force the browser to close or restrict its access to the Internet in order to save charge.

1. Go to Settings → Applications → Application Management → Mi Browser.
2. Choose the Battery. → No restrictions.
3. Enable AutoRun option (allows the browser to work in the background).

Also check if the memory optimizer blocks the browser:

1. Open Settings → Applications → Permissions → Autostart.
2. Find the Mi Browser and turn on the switch.
3. Return to Permissions → Other permissions and activate the Display over other windows (if available).

If the browser still hangs after these manipulations, the cause may be a conflict with other applications, such as antiviruses or antiviruses. VPN-Customers sometimes block network activity. Try temporarily disabling such programs and check the performance.

4. Update of the browser and firmware

The outdated version of the Mi Browser may contain performance-impairing errors.

1. Open the Mi Browser and tap on three points (⋮).
2. Select Settings → About the browser → Update.
3. If the update is available, install it and restart the browser.

If there are no updates, but the browser still slows down, the problem may be in the version of the MIUI firmware.

1. Go to Settings → About the phone → System update.
2. Click Check Updates and install the latest version (if available).

For devices with HyperOS (new firmware from Xiaomi), the process is similar, but the path may be different: Settings → About Phone → HyperOS Update.

💡

Updating the firmware not only corrects browser errors, but also optimizes the operation of the system kernel, which indirectly affects the speed of loading pages.

If updates are not available and your browser is slowing down, try installing the Mi Browser beta via APKMirror (at your own risk!).

5. Alternative browsers: when Mi Browser is not patchable

If none of these methods worked, it might be worth considering alternative browsers optimized for Xiaomi, and here are the best options for compatibility and performance:

When choosing an alternative, consider the amount of RAM of your device:

• 📱 For smartphones with 2-3 GB of RAM suitable Kiwi Browser or Firefox Lite.
• 📱 For devices with 4 GB of RAM and above, you can use Chrome or Brave.
• 📱 If privacy is important, choose Firefox or DuckDuckGo Browser.

Important: Before removing Mi Browser, disable it in settings as the default link app, otherwise the system can automatically open links in it. To do this, go to Settings → Applications → Default Applications → Browser and select an alternative.

6.Deep optimization: reset to factory settings

If the browser is slowing down against the background of system lags (interface freezes, slow application opening), the problem may be in the firmware itself, in which case the factory reset will help, but use it as a last resort.

Before discharge:

Backup photos and contacts

Record logins/passwords from important services

Make sure your phone has enough charge (at least 50%)

Download the latest version of the firmware (if you plan to re-flash)-->

To perform the discharge:

1. Go to Settings → About the phone → Reset settings.
2. Select Reset all settings (or Delete all data depending on the MIUI version).
3. Confirm the action and wait for the reboot.

After discharge:

• 🔄 Do not restore data from the backup immediately – check the browser on a “clean” system.
• 📱 Install only the necessary applications, avoiding “junk” utilities.
• 🔒 Turn off automatic app updates in the Play Market to avoid background load.

💡

If the browser still slows down after reset, the problem may be in the hardware (wearing out memory, overheating of the processor), in which case only a replacement device or repair will help.

7.Iron problems: when it is not the browser's fault

If the Mi Browser brakes even after all the manipulations, the reason may be hardware limitations:

• 🔋 Worn-out battery: at a health level below 70%, the processor limits performance.
• 🔥 Overheating: If the phone heats up while the browser is running, the frequency decreases CPU.
• 💾 Damaged flash memory: Slow writing/reading leads to lags.

To diagnose hardware problems:

1. Install the AIDA64 app and check the processor temperature in the Sensors section.
2. In AIDA64, open Storage → Read/Write Test – if the speed is below 50MB/s, the memory is worn out.
3. Check the battery health in Settings → Battery → Battery condition.

If hardware problems are detected:

• 🔋 For a worn-out battery, replace the battery at the service center.
• 🔥 When overheating, clean the device from dust (especially the charging and dynamics connector).
• 💾 If the memory is damaged, reflash the phone or replace the storage module (for models with removable memory).

💡

If your phone is older than 3-4 years, hardware lags are normal, and you might want to consider buying a new device or using lightweight browsers like Firefox Lite.
