I just discovered that watch will track sleep data only if it's in sleep focus (lemm.ee)

I do not understand this design decision. Why does it have to be in sleep focus to track sleep?!

My cheap Huawei fitness hand could auto track sleep irrespective of whether my phone was in sleep focus mode.

I’m not a wearable engineer so I wouldn’t know, but I assume it uses a combination of movement, heart rate, and other sensors. Fitbits for example can detect sleep down to the sleep stage you’re in.
