No idea about the Instinct syncing to Apple phone. But the light on the Instinct comes on automatically when you roll your wrist over to look at the time(in the dark, if you have it set to do so). It can also be the manual button.
I have the opposite problem - light stays on when running hard on the track. It's somehow sensing that I'm rolling my wrist over and keeping the light on. Small complaint, overall a good watch.
