Do I need my phone on to track my sleep data?

[Ronald7]

I had my watch on tonight when I got sleeping. The sleepmode was on. My telephone was off at night. Does my telephone have to be on so I can see my sleepscore on the next day? Now I did not see any sleepscore or grafic.

Phone does not have to be on.  By "sleepmode" on, if you meant "Begin sleep now", do not use that.  Just let fitbit figure out when you are asleep by itself.  If you meant the "Sleep mode" setting in Settings or "Quick Settings" that is okay but it doesn't affect how sleep is detected.  It is just to help prevent interruptions such as notifications at night.

Johnny thank you for your reply. I also see my grafics now. My bluetooth
connection with my fifbit was off so no grafics were displayed.

Let me clarify what I said about phone being off.  All data is still recorded on watch with phone off, sleep as well as other data such as steps, but won't get transmitted to phone and then synced to main Fitbit database until phone is turned on.
