Why is my iPhone running slow and how do I safely clear cache & cookies?

[emmy]

Hi everyone! After updating my iPhone 13, it’s been lagging more than usual. I heard that clearing the browser cache and cookies can speed things up, but I’m not sure if it might erase saved passwords or important data.
Can someone explain whether it’s safe to clear cache and cookies on an iPhone and share the correct steps to do it? Any tips would be really helpful!

iPhones may be slow when the storage is full, too many background applications, or obsolete iOS. To assist: this can be done by updating iOS, removing or unloading unused applications, clearing Safari history and web data (Settings Safari) and restarting your phone. This makes things run in a freer manner.

Your iPhone may slow down due to low storage, background apps, or cached data. To clear cache: go to Settings → Safari → Clear History and Website Data. For apps, delete and reinstall to reset cache, and free up storage in iPhone Storage.
