Clearing history on an iPhone is a straightforward process. You can go to Safari, tap on the bookmarks icon, and then 'History' where you'll find the option to 'Clear' at the bottom. You can choose how much history you'd like to clear. It's a good way to keep your data private. Is there a specific reason you're looking to clear your history, or are you just doing some routine maintenance? Feel free to share any concerns or questions you have!
