Charge HR not showing all sleep hours
I have been using a Fitbit Charge HR for 2 weeks now, and am quite happy with it--mostly. But I have noticed several times that is missing a lot of my sleep hours. Last night it was correct on when I went to bed (although I do find it amusing that it says it took no time for me to fall asleep (I KNOW I was awake for a minimum of 15 minutes). The problem is that it shows I got up about 1:50 am and never went back to sleep. I did get up at about that time, but only to get a drink in the kitchen, then use the bathroom and pet the cat briefly. I was up perhaps 5 or so minutes; then went back to bed and did not get up until the silent alarm (love this feature!) woke me up at 6:05 AM. I frequently get up at least once a night, and at times the sleep pattern has been recorded in two sections-before and after getting up for a few minutes. But several times it has recorded the same as last night; no more sleep recorded after I was up in the middle of the night for a few minutes. Is there any logical explanation for this happening?
