Sleep data changing weeks later

[wrleg]

I keep track of my fitness data in a paper planner and after a couple of days unable to sync I went to update my info in my planner. Suddenly my sleep info has changed. It shows me asleep more and awake less, although the total minutes are the same. It has changed for the whole month of Sept. (I don't have last months papers at hand right now.) For example 3 days ago it showed my Sept. 9 info as asleep 5 hrs 3 min and awake 34 min and now it says 5 hrs 17 min asleep and 20 min awake.  Has anyone experienced anything similar?

Hello @wrleg and a warm welcome.  There are several other posts about this.  It is being reported in both the Android and iOS forums.  This is an app issue, not a Versa issue.  Your description is the clearest one I have read.  The fact that you keep a paper record gives a better picture.

What version of the app (what type of phone) do you use? 

When you look at your sleeps stages graph, you normally see some real awake time.  But you usually see several (or many) small "awake" times of a minute or so.  Would you say that your time awake better correlates with you real time awake?

Fitbit is aware.

I use an app on my laptop that I downloaded from Google Chrome. I'm not sure if the actual sleep graph has changed or not. I'm not quite that **ahem**. lol

Same thing happened to me! 

I actually was staring at the app while it would do it a couple days ago.. it said 6hrs and 35 min of sleep then it would refresh to 7hrs and 5min of sleep for no reason. I attempted to screenshot it but I couldn't get it because it wouldn't change back. All my data improved sleep and I made my goal for previous days that I was significantly under. Looking at the sleep stages idk if they change their algorithm for calculation or what but I couldn't tell where the other 30min of awake time came from
