Xiaomi Redmi 9 smartphones remain popular due to availability and functionality, but over time, the accumulation of temporary files can slow down the device. Yandex browser stores data about visited pages, passwords and cookies, which creates a digital “heap” Not only takes up valuable space in internal memory, but also potentially jeopardizes your privacy if the phone gets accessed by unauthorized people.
The MIUI or HyperOS shell cleaning process has its own features that differ from pure Android. Redmi 9 owners need to consider the specifics of the system with background processes and file system access rights. Proper cleaning not only removes the list of sites, but also frees up the CPU resources for faster loading of pages in the future.
In this article, we will take a look at all the methods of deleting data, from standard settings to deep cleaning through the system menu of applications. You will learn how to selectively delete individual records without losing important saved passwords, and how to set up automatic browser maintenance. Proper cache management is the key to a long and stable operation of your gadget without the need for constant reinstallation of programs.
Why You Should Regularly Delete Browser Data
Accumulating your browsing history isn’t just a list of hundreds of links you once opened; it’s active databases that your browser constantly indexes to make things faster. However, on budget devices like the Xiaomi Redmi 9, RAM is limited, and a bloated database can cause micro-freezes when you switch between tabs or type text into your address bar.
There is also the digital hygiene aspect: Advertising networks use stored cookies and cache to track your preferences. Even if you use incognito mode, regular sessions leave a deep mark. Regular cleaning breaks the tracking chain and prevents intrusive advertising based on old queries from showing.
It’s important to understand the difference between a visit history and a cache. History is a text log, and cache is graphical and program elements of sites (pictures, scripts) saved for quick re-loading. Cache removal often solves problems with “curve” page display or authorization errors when the site “thinks” that you are still logged in, even though the data is outdated.
⚠️ Before clearing completely, make sure you remember passwords from important services or that they are stored in your Google account, as it may take time to restore access after deleting all data.
Delete History through Application Settings
The easiest and safest way to clear the log on Redmi 9 is to use the browser’s built-in menu, which allows you to flexibly configure what data will be deleted, leaving, for example, saved passwords or autocomplete forms intact.
To start, open the Yandex app on your smartphone. At the bottom of the screen, find a menu icon that usually looks like three horizontal bars or a square with dots, depending on the version of the interface. Click on it to deploy the main browser management menu.
Next, select Settings, which is often indicated by a gear. In the option list that opens, look for a privacy or history section. In current versions of Yandex.Browser, the path can look like History -> Clear History or be inside the Privacy menu.
- 🗑️ Browsing history: deletes the list of all web pages you visited for a selected period.
- 🍪 Cookies: erases login data and preferences, which may require re-authorization.
- 🖼️ Cache: Deletes temporary files of images and scripts, freeing up disk space.
- 🔑 Passwords: Deletes saved login and password bundles (be careful with this item!).
Once the required items are selected, the system will ask for confirmation of the action, which on Xiaomi is often accompanied by a pop-up with a timer or a re-press, and once confirmed, the process will take from a few seconds to a minute, depending on the amount of data accumulated.
☑️ Checklist before cleaning
Deep cleaning through Android system settings
Sometimes built-in browser features can’t delete all corrupted or locked files. In such cases, Xiaomi Redmi 9 works effectively with the cleaning method through Android system settings. This is a more radical approach that resets the application to the “as after installation” state.
Take your smartphone and go to the main Settings menu. Find the Apps section (or All apps depending on the version of MIUI). In the list of installed programs, find Yandex. If the list is long, search from the top of the screen.
Inside the app card, you're interested in the Memory button or the immediately available Clean (Broom icon) option. Here you'll see the separation between Clear Cache and Clear All Data. The first option is safe and only removes temporary debris. The second option completely deletes the history, logins, settings and browser database.
| Action. | What's removed | Impact on the account | Recommended frequency |
|---|---|---|---|
| Clearing the cache | Temporary files, pictures | No. | Once a week. |
| Clearing the data | All history, passwords, settings | Exit from all accounts | When selling or crashing |
| Deletion of the annex | All files + the application itself | Total reset | Very rarely. |
| Shutdown | Nothing's been deleted. | No. | To restart the process |
Using system cleaning is especially useful if the Yandex browser on your Redmi 9 has started to work unstable, crashes or does not open pages.Data reset often solves problems that cannot be fixed by a normal phone restart.
What to do if the “Clean” button is not active?
Deletion of individual records and synchronization
It doesn't always require a "nuclear winter cleanup" all the time. Often, the user only needs to delete a specific site from the story, for example, if you were looking for a gift for someone and you don't want them to accidentally see a request. On Xiaomi, this is done through the standard history interface.
Open the browser menu and go to History, and you'll see a list of all visits, sorted by date, to delete a particular entry, press your finger on the desired site (long tap), and you'll see a context menu or highlight mode where you can select one or more links and click the delete button (basket).
A big nuance for Redmi 9 owners is sync. If you have sync enabled with your Yandex account, deleting your phone history can automatically delete it on other devices (tablet, PC) where you log in. Conversely, if you want to clear only the local footprint, make sure that sync is temporarily disabled or use incognito mode for future searches.
- 📱 Local Deletion: Recording disappears only from current Xiaomi device.
- ☁️ Synchronized Deletion: Recording removed from the cloud and all attached gadgets.
- 🕶️ Incognito mode: history is not saved anywhere, the perfect solution for one-time searches.
To control sync, go to Settings -> Sync in your browser, where you can flexibly configure what's being sent to the server: bookmarks only, passwords only, or all of them, and turning off history sync is the best way to keep privacy on the shared device.

Use Alice's voice assistant to quickly go into incognito mode. Just say, "Alice, turn on incognito mode" to open a private tab without saving a story.
Features of working on MIUI and HyperOS
The MIUI shell (and the new HyperOS) installed on Redmi 9 has an aggressive memory management system that can automatically unload the browser from memory, which sometimes results in loss of session data, but not history. However, the Security system (green zipper icon) has its own cleaning tools that can conflict with browser settings.
Xiaomi’s Security app has a Cleanup feature, and if you use it, be careful: it can clear the cache of Yandex without your knowledge every time you run a scan, which is useful for saving space, but inconvenient if you want sites to load faster with cache.
To set exceptions, open the app Security -> Clean-up -> Settings (cogs) -> Blacklist or Exceptions. Add Yandex to the list of applications that do not need to be cached automatically. This will allow you to control when exactly to delete the history - manually as needed.
⚠️ Note: On some versions MIUI After cleaning the data, applications may reset permissions to access files. After clearing the history, check that the browser is again allowed to download files and save images.
Automation and privacy setting
To avoid manual cleaning every time, you can set up Yandex.Browser to automatically delete data when you exit, a Data Protection feature that erases history and cache every time you close the last tab.
To activate, go to Settings -> Privacy. Find the "Clear Data on Out" (or "Default Incognito Mode") switch. By activating this option, you ensure that your Redmi 9 will not have any digital footprints after the session is over.
You also need to pay attention to master password protection, so you can set the code in your privacy settings that you'll need to view your history or saved passwords, which adds another layer of security even if someone unlocks your screen.
💡
Automatic exit cleaning is the best balance between usability and privacy on Xiaomi smartphones.
Regular browser maintenance is a habit that prolongs the life of your smartphone. Using the methods described, you can be sure that your history remains your personal information, and Redmi 9 works as quickly as possible.
