Questions, answered
How accurate is sleep stage tracking?
Consumer trackers estimate stages from movement and heart-rate variability. They are good at total sleep time and decent at deep versus light splits, but not medical-grade. Treat trends as the signal.
Should I wear it every night?
Yes for useful trends, and charge while you shower. A single night's data is noise; two weeks is a pattern.
Does the screen disturb sleep?
Not with sleep mode enabled, which dims the display and silences notifications. Slim bands like the Xiaomi are the least noticeable overnight.
