While I have loved my Fitbit Surge from day 1, I only yesterday realized how amazingly precise the sleep tracker is. I noticed it when I took an afternoon nap after having been awake for about 8 hours. It logged my nap with impressive accuracy--seperately from my overnight rest.
It made me realize that if the sleep tracker were not precise, it would be confused by my relaxing in a recliner or sitting idly reading a book. It clearly can tell the difference between sleep and being idle. GREAT job, Fitbit!!

Sorry to disappoint you but naturally it does not get it right quite often. It varies a lot. Of course I am still impressed with the algorithm they wrte to try and guess when you fall asleep but it would not be a bad idea if it had a button/manual overrride that you press when you go to bed (like the FitBit One). If you stay still watching a film at the end of the day the Surge sometimes thinks it is the beginning of your sleep. This error can be compound by it missing you climbing a floor when you go upstairs to bed. I find that the Surge's altimeter is not as accurate as my old FitBit One's which is a pity. It misses the floor counts quite often while the FitBit On was almost spot on. Having said all of this I am quite happy with the Surge and its GPS capabilities.
