I usually track my sleep data with my watch but I fell asleep with it off. Yet it informed me of sleep data anyways. How did this happen? Was this just a rough calculation based on previous nights where I wore it?
It used magic
Mine doesn’t even track my data.
Was your iphone in your bed?
mine was, I was stuck staring at the tv with insomnia

Apple Watch always be watching
Its watchin time!
If your phone was on/near your bed, your phone tracked it instead.
Nobody here actually answered your question. Does your health app show Time in Bed or Time Asleep? Those are 2 different things calculated 2 different ways. Time in bed uses your phone to guesstimate your time spent in bed. It is a stupid feature and it’s ideal to turn it off. Turning it off doesn’t actually stop showing time in bed, but it does make it equal to time asleep. Time asleep is a metric that only your watch can calculate
Even without a watch, your iPhone can estimate how long you sleep based on your set sleep schedule and if/how long you use your phone at night. You need a watch for tracking sleep stages and more accurate data.
It was Apple watching you sleep
Did you have Sleep focus on? I’ve suspected it uses that.
lol is this a troll post
It calculates the time based on when sleep focus was turned on/off and when you used your phone during that time. I don’t usually wear my Apple Watch to bed and still get the “time in bed” data anyway.
