If you want to use the new gee-whiz features of iOS 9, like Picture in Picture to FaceTime with your significant other while you write a paper in Pages, or you want to Slide Over a Twitter app to keep track of all the goings on while you surf the web, you’re going to need a newer device.
However, all is not lost if you have an older device. Most of the power of iOS 9 is under the hood, making even older devices just a little more battery efficient, just a bit more useful.
