Modern Xiaomi smartphones running MIUI or HyperOS shells provide users with a wide range of privacy settings that by default may limit the operation of some websites. Cookies are small text data stored by the browser to store information about your preferences, login sessions and actions on visited resources. Without activated cookies, authorization in social networks, Internet banks and email services becomes impossible, and sites cease to “recognize” the user on repeated visits.
Often, owners of Redmi and Poco devices are faced with a situation where, after cleaning the history or updating the privacy settings, they are reset to the maximum level of protection, which leads to the fact that sites stop loading correctly or are endlessly redirected to the login page. In this article, we will discuss in detail how to activate the saving of these sites on various browsers preinstalled or popular on Android, and what nuances this process has on the devices of the Chinese brand.
It is important to understand that managing this data directly affects the balance between usability and digital security. Complete blocking of third-party cookies can disrupt widgets and ad integrations, but will increase anonymity. We will look not only at standard ways of inclusion, but also at hidden settings that can block files even with a basic permission.
Why do you need cookies on Android devices?
Cookies were designed to allow web servers to remember the state of user interaction. Because the HTTP protocol on which the Internet is based does not by its nature “remember” previous requests, it is the files that allow you to save goods in the shopping cart, keep a session open in VK or Telegram Web, and adapt content to your interests. On Xiaomi smartphones, this mechanism works similarly to desktop computers, but has its own characteristics due to the aggressive optimization of the battery system.
There is a separation between own and third-party files. Your own are created by the domain you are visiting right now, and they are necessary for basic functionality. Third-party ones are often used by ad networks to track user behavior across different websites. The MIUI security settings often limit the second type of data by default, which can break the functionality of some news widgets or authorization widgets through Google.
If you completely disable the storage of these sites, you will have to enter a login and password every time you go to the page, even if you did not close the browser tab. In addition, interface settings, such as a dark theme or the selected language on a particular resource, will be reset. For comfortable surfing on Xiaomi, you need to find a balance that works the main services, but limits tracking trackers.
⚠️ Warning: Periodic clearing of cookies frees up space in the browser cache and can speed up the device, but requires re-authorization on all sites.
Understanding how the browser processes this data helps to diagnose loading problems faster, and sometimes the site does not open because of the lack of Internet, but because of conflict versions of saved files or their blocking by the system's security mechanisms.
Cookie settings in the standard Mi Browser browser
Xiaomi smartphones have their own Mi Browser (or Mi Web) browser installed by default, which has integrated privacy settings. To activate the saving of these sites, you need to go to the application settings menu, usually through the profile icon or three points in the bottom navigation bar, where you need to select Settings.
The menu that opens should look for a privacy-related section. The path may be slightly different from the HyperOS and MIUI versions, but the logic remains the same. Look for Privacy and Security or Site Settings. This is where the cookie-accepting switch is located.
The system will offer several options for behavior: accept everything, block third-party or block everything. For the normal operation of most modern web resources, it is recommended to choose the “Accept All” mode** or, at least, not to block third-party data completely if you use complex services like Google Docs or office online platforms.
- 📱 Open the Mi Browser app and click on the profile icon or menu.
- 🔒 Go to Settings and select Privacy and Security».
- ✅ Find the "Accept cookie" option and activate the switch.
- 🔄 Reload the page where you had problems with authorization.
It is worth noting that Mi Browser also has an Incognito feature, in which cookies are not saved by definition, regardless of the general settings. If you try to log in in incognito mode, the system will consider you a new visitor each time.
💡
Use the Incognito mode to log in to sites from public Wi-Fi networks so that after closing the tab, all cookies are automatically deleted.
Activation of cookies in Google Chrome on Xiaomi
Google Chrome browser remains the most popular choice for Android users, and its settings are synchronized with your Google account. On Xiaomi devices, cookie management here also has its own features, especially in newer versions of Android, where Google has tight tracking restrictions. To access the settings, click on the three vertical dots in the upper right corner and select Settings.
The settings menu must find the Privacy and Security section, and inside this section is the Cookies option (or “Third-Party Cookies” in the updated versions), where the user can choose the level of security severity. The default option is often “Block Third-Party Cookies in Incognito mode”, which is the optimal balance.
If you do not have a login to a website, try temporarily changing the setting to “Allow all cookies”**. This action will remove restrictions, but reduce the level of protection from trackers. After performing the necessary operations (for example, confirming payment or login to the bank), it is better to return the settings back.
| Mode of work | Description of behaviour | Impact on websites |
|---|---|---|
| Allow everything | All types of data are stored | Maximum compatibility |
| Blocking Third Party (Incognito) | Protection only in hidden mode | Optimal balance |
| Block third-party | Banning ad trackers | Possible errors of widgets |
| Lock everything down. | Total prohibition of conservation | Authorization failures |
If the browser is closed in Task Manager, some cookies may not be updated, which will result in a quick session expiration.
☑️ Checking Chrome Settings
Settings in Yandex.Browser and other alternatives
Xiaomi users in Russia and the CIS often prefer Yandex.Browser for its synchronization with the desktop version and built-in Turbo mode. In this browser, cookie management is along the way: menus (three bars) → Settings → Sites → Additional site settings. Here you can customize exceptions for specific domains in detail.
Unlike standard solutions, Yandex offers a “Tracking Protection” mode that can automatically block third-party cookies even if the primary permission is given. If you encounter login problems, check if this mode is activated too aggressively. In Firefox for Android, similar settings are in the “Improving Tracking Protection” section.
For browsers like Opera or DuckDuckGo, the logic is similar, but the terminology may differ, for example, DuckDuckGo defaults to burning data after closing the tab, which requires a separate setup of Fireproofing for sites that require permanent login, and Xiaomi has more stable settings if the system allows the application to auto-run.
⚠️ Warning: Turning on Traffic Saving or Turbo Mode on third-party browsers can allow traffic through their servers, sometimes resulting in a loss of cookies when switching between Wi-Fi and the mobile network.
Remember that each browser installed stores its own set of cookies. Activating files in Chrome does not mean that they will appear in Mi Browser or Yandex.Browser.
The effect of energy saving on the operation of cookies
One of the specific problems of Xiaomi devices is the aggressive power saving system MIUI Optimization. Even if you set the cookies correctly in the browser, the system can “kill” the browser process in the background, which leads to a session reset and loss of temporary data. This is often perceived by the user as a cookie problem, although it is about memory management.
To avoid this, you need to go to Settings of the phone → Apps → All applications, find your browser and select Saving battery. Here you need to set the value “No restrictions”**. This will allow the browser to correctly manage temporary files even when the screen is off.
Also check the settings of the battery itself. In the Battery → Settings (cogs) section, make sure that the “Ultra-Energy Saving Mode” is not enabled, which blocks background activity of most applications, including network requests necessary for cookie validation.
- ⚡ Go to the settings of a specific browser application.
- 🔋 Select the item "Saving battery charge».
- 🚫 Set a “No Limits” mode for stable work.
- 📲 Check if the global energy saving regime is activated.
This measure is especially relevant for messengers in the web version (WhatsApp Web, Telegram Web), which require a constant connection. Without removing the restrictions from the battery, authorization will fly every 15-30 minutes.
Why do settings reset after rebooting?
Cleaning and management of stored data
Periodically, you need to not turn on, but rather to clean up the accumulated data if the site is not working correctly or you want to increase privacy. On Xiaomi, this can be done both through the browser settings and through the system menu. System cleaning is often deeper and removes the remnants of files that the browser may have missed.
For selective removal (for example, only for one problematic site), it is better to use internal browser tools. In Chrome, this is done through Settings → Privacy and Security → All sites. Here you can find a specific domain, click on it and choose Clear Data. This is safer than a complete cleanup of history, since it does not require you to re-enter all other services.
If you encounter a cyclical reload of the page or a 403 Forbidden error, try to completely clear the site data. Often old, damaged or conflicting cookies interfere with the loading of the new version of the page. Once cleaned, the page will load again and the files will be created again.
⚠️ Before clearing history and cookies, make sure you remember passwords from important services or they are stored in the password manager. Google/Mi Account, otherwise access to the accounts will be lost.
Use the sync function so that your cookie and password settings are saved in the cloud, so when you reset your phone or buy a new Xiaomi, you can quickly restore access to all the necessary resources just by logging into your account.
💡
Regularly selectively clearing cookies for specific problematic sites is more effective and safer than completely clearing the history of the entire browser.
