I Tested 4 Top Smartwatches in a Spartan Race and Sleep Tracking
Which smartwatch delivered the best fitness and sleep tracking performance?
1The Surprising Comfort of Sleeping with Four Watches
Testing revealed sleeping with four smartwatches was more comfortable than expected. Galaxy Watch Ultra 2 offered unique skin temperature readings, while Honor Watch 6 provided simpler sleep analysis. Amazfit T-Rex 3 Pro's 54 sleep score matched morning fatigue most accurately. Samsung's 72 score appeared unrealistic compared to actual sleep quality experienced.
2Brand Differences in Sleep Data
Galaxy Watch Ultra 2 measured deep sleep at 1h 3m, while Honor Watch 6 showed 2h 24m. OnePlus Watch 3 lacked SpO2 data, with Amazfit T-Rex 3 Pro delivering the most balanced metrics. Samsung's detection of 18 awakenings seemed exaggerated, whereas Honor and OnePlus's 2 awakenings underestimated reality.
3GPS Performance in Running Tests
During a 2.5-mile run, OnePlus Watch 3's GPS accuracy disappointed. Galaxy Watch Ultra 2 and Amazfit T-Rex 3 Pro provided most precise location data, while Honor Watch 6 produced misleading readings under tree cover. All watches succeeded in heart rate monitoring, but Samsung's inconsistent cadence measurements stood out negatively.
4Inconsistencies in Data Analysis
Honor Watch 6 failed in altitude measurements, while Galaxy Watch Ultra 2 completely miscalculated step cadence. OnePlus Watch 3's speed graph showed erratic spikes attributed to GPS issues. Amazfit T-Rex 3 Pro outperformed with consistent metrics across all parameters, though all four devices matched in heart rate accuracy.
5Spartan Race Final Comparison
In the muddy, intense Spartan race, only Amazfit and Samsung watches were tested. While GPS data showed no significant differences, Samsung's heart rate measurements contained three critical errors. Galaxy Watch's complete data failure between 10:46-10:50 was notable, whereas Amazfit maintained stable data streaming throughout the race.
6Striking Differences in Performance Graphs
Though speed and altitude data were similar between both watches, Samsung's cadence measurements proved completely inaccurate. This recurring issue in previous runs suggests algorithm problems. Amazfit's consistency across all metrics positioned it as the most reliable choice for fitness enthusiasts.
7Results for Different Use Cases
Amazfit's realistic sleep scoring excelled for rest tracking, while its GPS consistency stood out for workouts. Samsung's unique features like skin temperature monitoring were overshadowed by core metric inconsistencies. Honor Watch 6's simple interface suits beginners, while OnePlus Watch 3 underperformed expectations.
8Choosing the Ultimate Fitness Companion
After 12 miles of running, a Spartan race, and sleep tracking, Amazfit T-Rex 3 Pro emerged as the overall performance leader. Its consistent, accurate data across all tests proved decisive. While Galaxy Watch Ultra 2 offered innovative features, fundamental fitness tracking reliability issues affected its standing in rigorous testing conditions.
