Modern smartphones like the Xiaomi Redmi 9 accumulate huge amounts of temporary data during daily use. Cookies are small text records that websites store on your device to track activity, authorize and personalize content, and over time, they can number in the thousands, which negatively affects page loading speed and system resource consumption.
Clearing this data is an important maintenance procedure that should not be ignored. Periodic deletion of cache and cookies helps to eliminate site display errors, solves problems with endless downloads and frees up precious space in internal memory. It is especially important for owners of Redmi 9 to monitor this, since the amount of built-in storage in the basic modifications is limited.
In this article, we will take a look at all the cleaning options available, from standard system settings to advanced browser tools, how to perform the procedure selectively for a particular site or delete all data at once. Proper management of cookies is not only speeding up work, but also an important step in protecting your digital privacy.
Why you need regular cleaning of cookies on your smartphone
Many users mistakenly believe that cookies are harmless and do not require attention until the device starts to work slowly.In fact, this data may contain outdated session information, which leads to conflicts when logging in. For example, if a site has updated its security structure, old cookies on your Xiaomi can prevent correct authorization, causing cyclical redirects.
In addition, a crowded partition of temporary files affects the overall responsiveness of the MIUI operating system. When the browser has to process gigabytes of junk data, it consumes more RAM, which can lead to the closure of background applications. Free storage space is also critical for installing application updates and saving new photos.
⚠️ Before clearing completely, make sure you remember passwords from important sites, as after deleting cookies you will have to re-enter them.
There is a danger that the cleanup erases all your personal data irrevocably, in fact, it only affects temporary site files. Your contacts, photos, installed applications and documents remain completely safe. Deleting the cookie does not affect your browsing history unless you select the corresponding menu item separately, and this allows you to flexibly adjust the privacy level without losing navigation records.
Preparing the device for data cleaning
Before you start active actions, you need to conduct minimal preparations to ensure that the process goes smoothly. First of all, it is recommended to check the presence of important unsaved data in the open browser tabs. If you filled out long forms on sites but did not submit them, clearing cookies can interrupt the session and the information entered will be lost.
It’s also worth making sure your Redmi 9 device has enough battery life.Although the cleaning procedure is not energy intensive, suddenly turning off your phone while the system cache cleaning processes are running could theoretically cause software failures.It’s recommended to have at least 20-30% charge for quiet operation.
☑️ Preparation for cleaning
An important step is to understand the difference between cleaning up a particular application’s data and cleaning up the system completely. Xiaomi owners often confuse these concepts by removing the excess where it is not required. The system approach allows you to save application settings by removing only web debris. Below is a table showing what exactly is removed during different types of cleaning.
| Type of data | Clearing the cache | Cleaning cookies | Clearing all data |
|---|---|---|---|
| Saved passwords | Preserve. | Removed (if not synchronized) | Removed |
| History of visits | It's still there. | Preserves (usually) | Removed. |
| Temporary site files | Removed | Removed | Removed |
| Application settings | Preserve. | Preserve. | Dropped. |
Clearing cookies through the standard Mi Browser browser
Xiaomi Redmi 9 smartphones use its own Mi Browser browser by default, which has deeply integrated data management tools. This is the fastest way to clean up accumulated garbage without installing third-party software. The interface here is adapted to one hand, making navigation intuitive and easy.
To start, open the browser app and click on the menu represented by three horizontal bars at the bottom or top of the screen (location depends on the version of MIUI). In the list that opens, select Settings. Next, look for Privacy and Security. This is where all the controls for tracking and temporary files are concentrated.
Inside the privacy menu, click on the Clear Data button, and the system will prompt you to select a time frame: for the last hour, for today, for the week or for all time. For maximum efficiency, it is recommended to choose the All-Time option to ensure that old records that may have been forgotten in the depths of memory are deleted.
What to do if the cleaning button is inactive?
After selecting the period, make sure that the tick is opposite to the item "Cookies and site data." You can also further clear the cache and history if necessary. Press the confirmation button and the process will take only a few seconds. Redmi 9 will immediately report the amount of freed space.
Delete temporary files in Google Chrome
Most Android users prefer to use Google Chrome because of its synchronization with the desktop version and Google ecosystem.The cleaning process here is slightly different from the standard Xiaomi browser, but remains equally efficient.It is important to know the exact path to settings, as the interface can be updated.
Launch the Chrome app on your Redmi 9 and tap three dots in the top right corner of the screen. In the drop-down menu, select History and then again History in the submenu that opens. The alternative and quicker way is to select Settings right away, scroll down to Personal Data and click Clear History.
A window will open with a time range selection. As with the Mi Browser, select "All the time" for complete cleaning. Below you will see a list of data types. Make sure the cookies and site data switch is activated. The visual display will help you understand how much space the cleaning will take.
- 🗑️ Cookies can range from a few megabytes to hundreds of megabytes depending on activity.
- 🔒 Deleting cookies will log you off on most websites, requiring you to re-enter your password.
- 🚀 Cleaning often solves the problem of “infinite loading” pages.
After clicking the Delete button, the system will request final confirmation, which is done to prevent accidental loss of information. The process in Chrome can take a little longer than in the system browser if a lot of synchronization data has accumulated.
💡
Use the Incognito mode to visit sites that do not have to store cookies, in which the data is deleted automatically after the tab is closed.
Set up automatic cleaning and exceptions
Manual cleaning is effective, but it requires discipline. Fortunately, modern versions of Android browsers and MIUI shells allow you to automate this process or customize exceptions, which is especially useful for those who want to save logins on favorite resources, but clean up garbage from advertising sites.
Google Chrome and Mi Browser privacy settings often include the option “Always delete cookies when you exit,” which you can use to ensure that every session starts with a clean slate, but this can be inconvenient if you use email or social media frequently.
A more subtle setting is available through site exclusion management. You can add trusted resources to a whitelist, preventing them from being cleared even in a general reset. To do this, in the cookie settings menu, look for the item “Sites that can always use cookies” or similar.
⚠️ Adding too many sites to an exception nullifies the clean-up effect, as the main memory consumers will remain intact.
Also worth noting is the Safe Browsing feature in Chrome, which can block certain types of third-party cookies automatically, preventing them from accumulating. Proactive protection is often more effective than fighting consequences. On Redmi 9, these settings work stably and do not conflict with system optimizers.
Using the “Safety” application for comprehensive cleaning
The MIUI shell on Xiaomi Redmi 9 is famous for its built-in Security app, a powerful tool that combines antivirus, traffic control and memory cleaning, and many users underestimate its capabilities by limiting itself to garbage removal, but the functionality is much broader.
Launch the Security app (green zipper icon). Click on the Clean button. The system will analyze the device and suggest removing the Garbage. However, to work with cookies, click on Cleanup (or Deep Clean) at the bottom of the screen, and then go to the Apps or Big Files tab, where browser data is sometimes hidden.
A more direct path through this application is to select the Applications section -> Application Management. Find your browser (Chrome, Mi Browser, Yandex, etc.) click on it, then select Memory. Here you will see two buttons: Clear and Clear All. The Clear button usually deletes the cache, and Clear All resets the application completely, including cookies.
- 🧹 Standard Cleanup Deletes Temporary System and Application Files.
- 📱 Application memory management allows point-to-point deletion of browser data.
- 🛡️ The Security app also blocks ads that often put cookie trackers.
Xiaomi’s system tools are preferable to installing third-party “cleaners” from the Play Market. Third-party apps often contain advertising and collect data themselves, creating a paradoxical situation. The built-in Redmi 9 optimizer has access at a deeper level and works safer.
💡
The built-in MIUI tools are more efficient than third-party analogues, as they have system access rights and do not require additional permissions.
