Both watches offer comprehensive sleep tracking with different strengths.

Galaxy Watch 7 Sleep Features
Core Tracking:
- Sleep stages: Awake, REM, Light, and Deep
- Sleep consistency scoring
- Blood oxygen and heart rate variability
Standout Features:
- FDA-cleared sleep apnea detection (monitors over two nights)

Sleep Apnea Detection: Galaxy Watch 7's Advantage
The Galaxy Watch 7 can identify moderate to severe obstructive sleep apnea. This FDA-cleared feature could be life-changing.
Sleep apnea affects millions who don't know they have it. Symptoms include snoring, daytime fatigue, and waking unrested. Left untreated, it increases heart disease and stroke risk.
The Charging Strategy
Neither watch can charge while tracking sleep:
Galaxy Watch 7: Longer battery means 30 minutes of charging before bed provides enough for sleep tracking plus most of the next day.
Apple Watch Series 11: Charge during morning routines. The 24-hour battery makes this manageable.
Bottom line: Galaxy Watch 7 wins for sleep tracking with its FDA-cleared sleep apnea detection. Apple Watch's Sleep Score provides simpler daily feedback.
