I want to have the screen on all the time when I charge
When I use the iPhone 6 (latest OS) I want to have the screen on all the time when I use it in the car with map program.
I know that it can be set to "Always on", but I want the screen to be closed after 2 minutes when using battery.
Do I have to change these settings every time I shall use it in the car?
iPhone 6, iOS 9.1
