This tutorial was last updated on September 23, 2013. It is intended for users running iOS 7 on their iPhones. If you have an older version of iOS on your device, please refer to this tutorial.
Safari's Settings should now be displayed. Scroll to the bottom of this page until the Clear History option becomes visible.
Your browsing history is essentially a log of the Web pages that you have previously visited, helpful when you want to return to these sites in the future. However, you may on occasion have the desire to completely remove this history from your iPhone.
If the Clear History link is blue, that indicates that Safari has some past browsing history stored. If the link is gray, on the other hand, then there are no history records to delete.
To clear your browsing history you must first select the Clear History button, circled in the example above.
