I think this has been a problem since iOS 9, when I used to plug my phone into the dock to listen to radio/podcasts at night with the screen unlocked after a few minutes the screen would dim which I prefer. Now this doesn't happen, I guess it must be because it connected to a power supply because when the phone isn't plugged into anything then I do get the desired effect of the screen dimming.
Is this a new thing or just a software bug and does anyone now a fix?
