Look at screenshot and specifically SLEEP STAGES vs TOTAL SLEEP (does NOT add up). I clearly did not just have 1:40 mins 'Actual Sleep Time'. It's annoying enough that it ONLY tracks the 'in bed time' on the weekly chart, but on top of it it shows a completely inaccurate actual sleep time (see bottom of image) when you are up for an extended period of time during the night.
It is totally blocking out the first half of the night. It's even grayed out. When the awake time is not as long it does a fine job recording the whole night.
Solved! Go to Solution.
As in your example above: 1 hour and 40 minutes less 9 minutes awake time.
Your sleep data is not wrong. It is showing two different sleep cycles and it shows the sleep time for each different cycle. If you go to the wear app, in the sleep tracking, you can delete the erroneous sleep segment by clicking on the 3 dots on the upper right, choose delete, and then choose the time sequence you want to delete. You can also switch from one sleep cycle to the other by clicking on the cycle you want with your finger. The sleep counter does show the total time among all sleep cycles, but does also show each sleep cycle individually.
The watch tracks sleep by your heart, respiration and pulse rate, so it may think you are asleep when you are not: such as lying on the couch, or watching TV, or reading a book, or any time you are at rest when these bodily functions slow down.
You have to recognize that these sensors only approximate what it believes are sleep cycles based on that specific criteria. The sensors are not inside your brain, which would be the only true way to tell whether you are asleep and what phase of sleep you are in.
So, if you weren't actually sleeping during that specific 1:40, delete it. If you were actually dozing or napping, then it's all fine. If that time during the "gap" you were in bed, but awake (like you got up for the bathroom and couldn't get right back to sleep) it would show as a break in sleep, not just a huge orange "awake" ribbon.
