The Smartwatch Market in 2026
Apple Watch and Samsung Galaxy Watch together account for over 60% of global smartwatch sales. Both have matured into serious health monitoring platforms rather than just notification mirrors. The Apple Watch Series 10 and Samsung Galaxy Watch 7 represent the best each company offers at the flagship level below the ultra tier.
Health and Fitness Tracking
Apple Watch Series 10: Heart rate, ECG (electrocardiogram), blood oxygen (SpO2), skin temperature, cycle tracking, crash detection, fall detection, sleep staging (REM, Core, Deep). New: depth gauge and water temperature for diving (up to 6m). FDA-cleared ECG and irregular rhythm notifications.
Samsung Galaxy Watch 7: Heart rate, ECG, blood pressure monitoring (requires calibration via Samsung Health Monitor app), body composition (BIA sensor), skin temperature, sleep staging, sleep apnea detection (FDA-cleared). New: Advanced sleep coaching with personalized recommendations.
Key difference: Samsung Galaxy Watch 7 includes blood pressure monitoring — a feature Apple Watch still lacks in 2026. Apple Watch has better third-party health app integration (most health apps target watchOS first) and longer FDA clearance history for ECG.
Winner: Samsung Galaxy Watch 7 for sensor breadth (blood pressure monitoring). Apple Watch Series 10 for health app ecosystem and FDA-cleared feature reliability.
Battery Life
Apple Watch Series 10: Apple-rated 18 hours. Real-world typical use: 14-16 hours with always-on display enabled. Requires daily charging. Low Power Mode extends to ~36 hours by disabling most features.
Samsung Galaxy Watch 7: Samsung-rated 40 hours. Real-world with always-on display: 28-32 hours. 2-day battery is consistently achievable in typical use.
Winner: Samsung Galaxy Watch 7 decisively. Nearly double the real-world battery life is a meaningful daily experience difference. Apple Watch requires nightly charging without exception; Galaxy Watch 7 can go two days comfortably.
Display
Apple Watch Series 10: Largest Apple Watch display ever — 46mm model has 2000 nits peak brightness, thinnest Apple Watch chassis (9.7mm). Always-on Retina LTPO display with up to 2000 nits outdoor brightness.
Samsung Galaxy Watch 7: 44mm Super AMOLED, 1000 nits peak, always-on display. Circular design versus Apple Watch rectangular form. Display quality is excellent but peak brightness is notably lower than Apple Watch Series 10.
Winner: Apple Watch Series 10 for display brightness and visibility in direct sunlight. Samsung Galaxy Watch 7 for circular design preference.
Apple Watch Series 10: Requires iPhone. Incompatible with Android. Full feature set only with recent iPhone models.
Samsung Galaxy Watch 7: Works with any Android phone running Android 10+, not just Samsung phones. Best features (blood pressure monitoring, body composition) require Samsung Galaxy phone with Samsung Health Monitor app. Works with Google services and all Android apps.
Winner: Samsung Galaxy Watch 7 for platform flexibility. Apple Watch is iPhone-exclusive — if you use Android, Apple Watch is not an option.
Design and Build
Apple Watch Series 10: Rectangular case, aluminum or titanium, 9.7mm thin (thinnest Apple Watch), magnetic fast charging. New colorways for 2025.
Samsung Galaxy Watch 7: Circular case, aluminum, 9.7mm. Sapphire crystal glass on base model. Circular design is preferred by many users accustomed to traditional watches.
Winner: Personal preference. Circular design: Galaxy Watch 7. Thinner profile: tied. Material options: Apple Watch (titanium option).
Price
Galaxy Watch 7 is $100 cheaper than equivalent Apple Watch Series 10 at the base tier.
Final Verdict
Buy Apple Watch Series 10 if: You use iPhone. You want the brightest outdoor display. You use many third-party health apps. You value the Apple fitness and health ecosystem.
Buy Samsung Galaxy Watch 7 if: You use an Android phone. You want 2-day battery life. You want blood pressure monitoring. You prefer a circular watch design at a lower price.
