The situation where Mi Browser suddenly reboots an open tab when switching to it from another application is familiar to many owners of Xiaomi, Redmi and Poco smartphones. You read an article, go to answer the messenger, and when you return, you see a flashing download screen instead of stored content, a phenomenon known as “tab reset” or “downloading from memory”, annoying and reduces the productivity of the device.
The main reason lies in the aggressive policy of managing MIUI and HyperOS. The system seeks to free up resources for active processes by forcibly closing background applications, including the browser. However, the problem is not always just the hardware; often the fault of software conflicts or incorrect power consumption settings.
In this article, we will discuss in detail the mechanisms of Android on Xiaomi devices and provide specific instructions for stabilizing the Mi Browser. You will learn how to properly configure the system settings so that the browser saves your tabs even if there is a lack of free memory.
Aggressive Memory Optimization in MIUI and HyperOS
Xiaomi’s operating shells are famous for their advanced but sometimes overly aggressive resource management system. When free RAM (RAM) becomes scarce, the system’s algorithms begin to forcefully terminate applications that are in the background. Mi Browser, like any modern web browser, consumes a significant amount of resources to render complex web pages.
The Memory Killer mechanism in the Linux kernel on which Android is based receives signals from the MIUI shell to vacate space. As a result, the system “kills” application processes that have not been used for a long time, or those that consume too much memory. This is standard behavior for mobile OSes, but on Xiaomi phones it is often set to prioritize autonomy rather than multitasking.
⚠️ Warning: Forced memory cleanup by third-party accelerators or clinders can make matters worse.The system perceives the vacated space as a signal to even more aggressively close background processes, including browser tabs.
Users often notice that the problem is more pronounced after a firmware update, because newer versions of MIUI can change the thresholds of the power saving mechanisms. If you have a 4GB or 6GB model, the system will try to keep only the most necessary applications in memory, sacrificing heavy web pages.
Energy saving settings and background activity restrictions
One of the main reasons for tab resets is the energy saving settings applied specifically to the Mi Browser application. The system can restrict the background activity of the browser to extend battery life. To check and change these settings, you need to go to the settings menu of your device.
Go to Settings → Applications → All applications and find Mi Browser. From the menu that opens, select Energy Saving. Here you will see three options. To keep tabs running, select No Limits mode, which will prevent the system from forcibly stopping the browser process even if the screen is turned off or another application is running.
☑️ Setting up energy saving
Also worth paying attention to the general mode of energy saving of the phone: if activated mode "Energy Saving" or "Ultra-energy saving", the system will ignore the individual settings of applications and severely limit all background processes, in such modes, the browser will always be unstable.
- 🔋 No Limits mode allows the browser to work in the background without time and resources restrictions.
- 📉 Standard mode can limit background activity after 15 minutes of downtime.
- ⛔ A strict restriction completely prohibits background work, which is guaranteed to result in tab resetting.
Lack of RAM and work with tabs
The number of tabs open directly affects the consumption of RAM. Each open page is a separate process that takes up space in RAM. If you have 20-30 tabs open with “heavy” media content, even 8 GB of memory can be filled to the full, which inevitably leads to the unloading of old tabs.
Modern websites are loaded with high-resolution scripts, animations and video, making them very heavy for mobile processors. When you switch between tabs, the browser has to re-upload content if the process is killed by the system. This is not a browser error, but a physical limitation of the device's available resources.
To minimize resets, it is recommended to use the “Close all tabs” feature periodically or group them by topic, and you can also turn on the “Traffic Saving” mode in the browser itself, which makes it easier to display pages, reducing memory load, although this can worsen the quality of graphics.
⚠️ Warning: Don't keep tabs with online broadcasts or video conferencing in the background open unless you're using them right now, they consume a huge amount of memory and provoke the system to shut down other processes.
Expansion of RAM and virtual paging
Many modern Xiaomi models support memory expansion technology known as Memory Extension or Virtual Paging.This feature uses a portion of embedded storage (ROM) as an addition to RAM. Enabling this option can help keep more apps and tabs active.
To activate this feature, go to Settings → Advanced Settings → Expansion of memory. Here you can choose the amount of memory you add (usually from 2 to 5 GB). Once turned on, the phone will suggest a reboot. It should be noted that the speed of virtual memory is lower than that of physical RAM, but for storing background tabs this is quite enough.
How does virtual memory work?
But there are some nuances to using this feature: If your drive is more than 85-90% full, the system won't be able to use the memory expansion effectively, and performance may even drop.
- 🚀 Expanding memory allows you to keep more applications in the background without rebooting them.
- 💾 The function requires at least 5-10 GB of free space on the internal storage.
- ⚙️ Efficiency depends on the speed of your storage (UFS 2.1, 3.1 or 4.0).
Clearing the cache and resetting browser settings
Accumulated over time, cache and cookies can cause conflicts in the work of Mi Browser. damaged temporary files can lead to incorrect memory management and frequent resets. Regular cleaning of browser data helps to eliminate software errors.
To clean up, go to Settings → Apps → All apps → Mi Browser → Storage. Click the “Clean” button to remove the cache. If the problem persists, you can try clicking Reset (or Clear All), but keep in mind that this action will delete the history, saved passwords and browser settings.
| Type of data | What's removed | Impact on the problem | Do I need to log in to the account? |
|---|---|---|---|
| Cash. | Temporary files, images of websites | High (removes rendering errors) | No. |
| Data (Dumping) | Tabs, history, passwords, settings | Maximum (full return to factory condition) | Yes (for synchronization) |
| Cookie | Authorization data on websites | Medium (solves entry problems) | Yeah (I'll have to re-enter) |
After cleaning, it is recommended to restart the smartphone, which will allow the system to redistribute resources and start the Mi Browser from scratch, without baggage of old errors.
💡
Before resetting your browser completely, make sure you remember passwords from important sites or that they are stored in your Google/Xiaomi account, otherwise you may lose access to your data.
Alternative browsers as a solution to the problem
If system optimization doesn't work, it might be the Mi Browser engine itself. Some versions of the app may not be optimized well for your particular phone model or Android version. In that case, the smart solution would be to install an alternative browser that better manages memory.
Popular alternatives like Chrome, Yandex Browser or Via Browser have their own data compression and tab management mechanisms, such as the Via Browser, which takes only a couple of megabytes and consumes minimal resources, which is ideal for devices with low RAM.
💡
Changing your browser to a lighter analog often solves the problem of resetting tabs more effectively than trying to optimize the system Mi Browser.
When you install a new browser, the system can continue to apply restrictions to it by default. Remember to set the energy saving mode for the new application to “No restrictions” immediately after installation, using the instructions from the previous sections.
- 🌐 Chrome: Standard Solution, Well Integrated, But Can Be Heavy.
- 🚀 Via: Ultralight browser, ideal for weak devices.
- 🛡️ Brave: Blocks ads, which reduces the load on the processor and memory when loading pages.
