When in sleep mode, does the FitBit flex recognize the difference between when you are truly asleep rather than lying still and relaxed, but mentally awake? Or would it log all time lying still in bed as part as sleep as long as you are not moving?

I got up 2 nights ago, sat and read in the living room for 2 hours, apparently with my left hand (wearing flex) motionless most of the time. That time was logged as sleep.
But, in general, I think over time, flex records sleep fairly well.

@Stephen1227 Read the sleep faq?
It seems pretty accurate with my sleep.

It even knows when I go to the bathroom! Pretty accurate for me to...

It doesn't seem to be accurate for me. I spend most of my nights awake and fitbit will say awake (0), restless (3x). I'm pretty disappointed with the sleep mode.

@JaimeW From that description, it sounds like you have your tracker set to "Sensitive" mode. If that is the case, I'd recommend setting it to "Normal" instead. This setting will be more accurate for most users, and will probably provide you with better results.

I put my One on the sensitive setting, and sleep with it attached to my underwear. I feel it is most accurate there, and yes, it can tell the difference between sleeping and laying very quietly.
I first tried using the wristband, and it seemed like the results were not accurate at all, even on my non-dominant hand on the "normal" setting.
Sorry, I missed the fact you were asking about the Flex.

I have tried sensative and normal mode and my experience has been that it does not recognize the amount of time I am awake. For example, I do see a red line at a time when I know I was awake, but fitbit shows that I went right back to sleep when in actuallity I was laying very still trying to go back to sleep. (It's like I can't get my brain to shut off.) After a few nights I decided to test this. When I would wake up in the middle of the night and lay there trying to fall back asleep if it went past 15 minutes and I still wasn't asleep I moved my arm. On the fitbit it recorded that I woke up and fell back asleep for 15 minutes and woke up again. So, if I want it to track the time I am laying there awake it would appear that I would have to keep moving my arm, which would of course make it even harder to fall back asleep. I am sure I need to see a sleep specialist since it is very frustrating to lay there awake several times a night. My husband doesn't have the sleep issues I have and he thought it was going to show no movement all night for his sleep. It was really cool to see that he has a normal sleep cycle where he moves roughly every 90 minutes.

Maybe it is to tight or too loose. It knows when I wake up. I am trying to see if I sleep better with out sugar. What do dreams do to the sleep tracker??

Thanks @Odyssey13 I watch my husband some nights and it's like he is doing hard labor in his sleep. He also moves around a ton more shen we eat something that gives him heartburn. I am really enjoying the sleep part of the fitbit. It is interesting.. My sleep% went down today because I didn't push the button as soon as I woke up. Says I wasted almost an hour in bed that I coulf of been working out before I had to go to work. 2 of the 3 nights I got a 98-99% sleep. Oh ya great 4-6 hours

@lynnbaum How have things been going for you with sleep?
I never get more than about 80% sleep efficiency.

I have a One, but I do know that it's just recording movement or lack thereof, not actual sleep.
There are times that I'm awake but lying quiet, body mostly relaxed, but definitely NOT asleep. The next day I check after syncing and it recorded me as asleep.

You can edit your sleep log to remove the time you were up but forgot to turn off sleep mode. Go to the LOG screen then Sleep. Above and to the right of the sleep bar you'll see a little page symbol. Click on that to edit.

I have steps in the middle of the night because we have an older dog. I we didn't and I had steps show I would know I was sleep walking. This would be great for people that eat in the middle of the night. There is no way I am giving up sleep to eat.

I set my flex to sleep mode when i get in bed. In the morning when i sync it, it shows that i hve been in bed much longer than i actually was. I usually go to bed at 10 pm, but my flex says that sometimes i go to bed much earlier than that. It is recording me as sleeping when i am driving home from work, or when i'm sitting watching TV, even though I have not put it into sleep mode. How can I get the most accurate log of my actual sleep?
