He Tracked His Sleep With a Galaxy Watch, Then Kicked His Phone Out of Bed — Deep Sleep Rose 43 Minutes a Night
3 min read · RealCase summary
One writer noticed he was regularly falling asleep with his phone resting on his chest, checking it multiple times a night out of habit rather than need. To see what that was actually costing him, he ran a 30-day experiment removing the phone from the bedroom entirely.
He tracked his sleep stages nightly using a Samsung Galaxy Watch, comparing his phone-free nights against his previous baseline rather than relying on how rested he felt subjectively.
Over the 30 days, his tracked deep sleep rose by 43 extra minutes a night — a single-habit change he credits to removing the low-level mental stimulation of a phone within reach at bedtime.
