Annoying lag while searching in iOS Safari
I had the exact same problem! I got the following solution, courtesy of a call to Apple.
- Go to Settings > Safari
- Select "Clear History and Website Data" (note: this will wipe your history on your phone and any devices that sync their Safari data with your phone's over iCloud.
- Change the Block Cookies setting to Always Block.
- Close Safari from the app switcher.
- Change the Block Cookies setting back to Allow from Websites I Visit.
- Enjoy your non-laggy Safari!
