Over the years, Safari on the iPhone, iPad, and iPod touch has become more capable, incrementally gaining features from its desktop counterpart. One of those features—AutoFill—can come in extremely handy, but doesn’t necessarily get used a lot because it’s not turned on by default. To add this trick to your mobile web browsing arsenal, open the Settings app, tap on Safari, and then tap on AutoFill. On the screen that appears, you’ll need to turn Use Contact Info on, Names & Passwords on—if you want—and tap the My Info area to select your own entry from your list of contacts, letting Safari in on specifics like your address, phone number, and other details it can use to automatically populate forms, saving you time and frustration.
