Multi­tasking has always been a smart way to switch between apps. Now it’s even smarter!

iOS 7 learns when you like to use your apps and can update your content before you launch them now. So if you tend to check your favorite social app at 9:00 a.m. every day, your feed will be ready and waiting for you.

On top of that, smart multi­tasking leads to intelli­gently scheduled updates:
iOS schedules updates during power–efficient times. Like when your device is on and connected to Wi–Fi. The goal is not to drain your battery unnecessarily.
