A phone call woke me up today at 8. But I remained in bed, lying, browsing instagram till 9:15. At 9:15 I took of the ISM and put on my epix. Then I looked into connect to see my sleep ended at 9:15 according to garmin.
Does it mean, the almost 150€ high end device which only purpose is to monitor my sleep quality, stages ect. actually does recognize end of the sleep only by taking off the device? In such case, how can it recognize my sleep stages, as it cannot distinguish between sleep/no-sleep?
