I'm intrigued by the new Bedtime function within the Clock app, which feeds data into the Health app under Sleep -> Sleep Analysis. I have used it for the last two nights, and for both times I've left my iPhone 6 on bedside table. Both times it has recorded the entire period as 'In Bed' and none of the time as 'Asleep'. I appreciate the app is probably a bit limited in what it can achieve, but I'm curious if there's a way for it to record a portion of the time as 'Asleep'? The blurb within the Health app seems to suggest that the iPhone can do this alone.
