8 great features in iOS 9 (and how to use them)

Apple's iOS 9 has dozens of new features and here are a handful that every iPhone and iPad owner should know about for longer battery life and improved usability.

Apple spent a year revising iOS 8 to its current iteration and while there are tons of new features, some are "must haves" to make the mobile experience better.

You can now save battery life in a pinch, use the iPad's keyboard as a trackpad, block unwanted content to speed up Safari, get faster access to Apple Pay and more. Did you know that iOS also has a new "back" button, similar to Google Android? It's a different implementation but it comes in handy.
