Why clear cookies on Xiaomi and what does it do?
Cookies (or cookies) are small files that websites store on your phone to store data about visits, authorization and personal settings. On Xiaomi smartphones (including Redmi, POCO, Black Shark), cookies accumulate in browsers, instant messengers and even some system applications. Over time, they can take up extra space, slow down the device or create privacy risks.
Clearing cookies on Xiaomi helps:
- 🚀 Speed up the loading of web pages (especially if the browser is slowing down")
- 🔒 Remove traces of visited sites (useful when using public Wi-Fi)
- 📱 Free up space in memory (on some models, cookies take up to 500 MB!)
- 🔄 Solve authorization issues (if sites are constantly being “thrown out” of your account)
But there are nuances: after cleaning the cookies, you will have to re-enter logins / passwords on frequently visited sites, and some settings (for example, language or theme) will reset, so before the procedure, you should weigh the pros and cons.

Where cookies are stored on Xiaomi: browsers vs system files
On Xiaomi phones, cookies are divided into two types:
- Browser cookies are stored in applications like Google Chrome, MIUI Browser, Firefox or Opera, and can be deleted directly from the browser settings.
- System cookies – created by some applications (e.g. Mi Account or Mi Cloud) and stored in the /data/data/ folder. their cleaning requires access to root rights or the use of special utilities.
Most users simply clear cookies in the browser, which solves 90% of the problems, but if you notice that after deleting cookies in Chrome, some sites still "remember" your data, then they are stored in system files, in which case, resetting the application settings or completely reinstalling the browser will help.
