I have just purchased my first Fitbit, the Fitbit Flex 2 and I'm quite confused about the total sleep stats. Fitbit seems to only treat deep sleep as time spent 'asleep' and light sleep is considered 'restless' which apparently isn't regarded as 'sleep'. As a previous Jawbone UP user I am used to seeing my total hours of sleep (e.g 6h) and then that is split into deep and light sleep (e.g. 3.5h deep sleep, 2.5h light sleep). From what I can tell, on Fitbit you can only see either the total time spent in bed (6h) which won't be split into deep/light sleep or the view where deep/light sleep are separated, but in this scenario the total sleep would only be 3.5h, even though I have actually slept for 6h.
I realise in the web dashboard I can see 'time spent in bed' but as only deep sleep counts towards the score, my stats are going to be way off my sleep goal, which is 8h. Does Fitbit really expect people to have 7-9 hours of deep sleep per night, as that is their recommended goal? Also, on the app, if I want to look at the broken down view of deep/light sleep it doesn't seem to show 'total time in bed' at all, and vice versa.
Is there a setting I am missing somewhere that would rectify this?
