I recently got an iPhone6. I used to have an iPhone 4s.
On the 4s, if automatically shut down after some period of activity (5 min?).
I can't figure out how to make the iPhone 6 do that. I have to turn it off manually with the right side button (sounds like a switch click when pressed).
That's not terrible, but sounds like a backward step.
Is there a way ti do that on an iPhone 6?
