Samsung Galaxy Watch Ultra Still the King of Smartwatches
Having spent weeks testing the Galaxy Watch Ultra in a variety of real-world scenarios, from trail runs and indoor workouts to sleep tracking and everyday office use, I can confidently say this smartwatch still stands out.
Samsung has packed it with features designed for athletes, adventurers, and anyone serious about health tracking, making it a versatile wearable for almost any lifestyle.
The combination of rugged build, accurate sensors, long-lasting battery, and smart functionality ensures the Galaxy Watch Ultra remains one of the most capable and reliable smartwatches in 2025. In this Galaxy Watch Ultra Review, we’ll dive deep into its design, performance, fitness capabilities, and hands-on experience, so you can see exactly what it feels like to use day after day.
Design & Build Quality
Right out of the box, the Galaxy Watch Ultra exudes a premium, rugged vibe. Samsung has gone all-in with a titanium case that’s both lightweight and highly durable, paired with a sapphire crystal display for maximum scratch resistance.
The watch is MIL-STD 810H certified, meaning it can withstand shocks, vibrations, and extreme temperatures, perfect for hiking, biking, or just keeping up with a busy lifestyle. Add in 10 ATM / IP68 water resistance, and you can swim, shower, or kayak without worry.
Hands-on insight: After wearing it for a couple of weeks, I didn’t notice a single scratch. Even after a muddy trail run and several indoor gym sessions, the titanium case held up beautifully. That said, at 47mm, it’s a larger watch, users with smaller wrists may find it a bit bulky.
Display & Brightness
The Galaxy Watch Ultra features a 2-inch AMOLED display that’s both vibrant and crisp, making it a pleasure to use outdoors. Even under direct sunlight, the screen remains easily readable, a welcome feature for runners, hikers, or anyone spending time outside. The always-on display is a thoughtful touch, letting you check notifications or glance at fitness stats without having to lift your wrist or tap the screen.
Navigation feels smooth and intuitive, thanks to a combination of touchscreen controls, the rotating bezel, and side buttons. I especially appreciated the Quick Action button, which makes starting workouts or opening apps mid-activity fast and hassle-free.
Hands-on insight: During outdoor runs, I could manually adjust brightness to see stats clearly at a glance, and the touchscreen remained responsive even with sweat or light rain. The tactile buttons were easy to use mid-workout, proving that Samsung has designed the Galaxy Watch Ultra with real-world usability in mind.
Performance
Under the hood, the Galaxy Watch Ultra is powered by Samsung’s latest 3nm chipset and runs on Wear OS with One UI Watch. This combination delivers smooth, responsive performance, whether you’re scrolling through apps, tracking a workout, or responding to notifications.
Samsung has refined the experience considerably: apps launch quickly, menus navigate effortlessly, and multitasking rarely causes any hiccups. The One UI Watch interface is intuitive, making it easy for both long-time Samsung users and newcomers switching from other smartwatches.
Hands-on insight: During testing, I streamed music over LTE while running multiple fitness apps, and the watch handled it all without any slowdown. Notifications arrived promptly, and syncing with my Samsung phone felt seamless, whether using Samsung Pay, adjusting smart home devices, or controlling media playback. Overall, the Galaxy Watch Ultra feels fast, reliable, and polished, even under heavy daily use.
Fitness, Diving & Health Tracking
Samsung has long prioritized fitness, and the Galaxy Watch Ultra continues that tradition with a comprehensive health and activity suite designed for serious athletes and everyday users alike.
- Heart Rate Monitoring: Tracks your heart rate continuously and stays accurate even during high-intensity workouts, giving you reliable data for training and recovery.
- ECG & SpO2: Monitors your heart rhythm and blood oxygen levels, offering deeper insights into cardiovascular health.
- Sleep Tracking: Measures sleep cycles and provides actionable feedback to help improve overall rest and recovery.
- Stress Tracking: Uses heart rate variability to help manage stress and optimize recovery routines.
- Advanced Workout Metrics: Includes VO2 max estimation, running form analysis, and vascular load tracking for a more in-depth performance review.
- Dual-frequency GPS: Ensures highly precise location tracking, even in dense forests, urban streets, or challenging outdoor terrain.
- Hands-on insight: In real-world testing, the heart rate and GPS sensors were impressively accurate, even during long runs, cycling sessions, and indoor HIIT workouts. Sleep tracking provided useful insights for adjusting recovery routines, while stress monitoring helped fine-tune daily activity levels. Overall, the Galaxy Watch Ultra proved to be one of the most reliable health-focused smartwatches I’ve personally tested, making it a standout choice for fitness enthusiasts and adventurers alike.
Battery Life & Charging
Battery life has always been a key factor for any smartwatch, and the Galaxy Watch Ultra doesn’t disappoint. In real-world use, it comfortably handles two full days of mixed activities, including workouts, notifications, GPS tracking, and sleep monitoring. When relying heavily on GPS during long runs or hikes, you can expect 24–36 hours of usage, while the power-saving mode can extend battery life up to an impressive 100 hours, perfect for multi-day trips where charging isn’t an option.
Charging is just as convenient. A quick 30-minute charge gives you enough power to last a full day, meaning you don’t have to plan around long charging sessions.
Hands-on insight: Over a week of heavy use, the watch consistently held up to these numbers, even with daily runs, gym sessions, and overnight sleep tracking. For anyone who spends long hours away from home or enjoys extended outdoor adventures, the Galaxy Watch Ultra’s battery is reliably long-lasting and worry-free.
Samsung Galaxy Watch Ultra Enhancements You’ll Love
Samsung has introduced several thoughtful enhancements in 2025 that make the Galaxy Watch Ultra even more practical and enjoyable to use.
One of the standout additions is the Double Tap gesture, which lets you quickly access your favorite apps or functions without navigating through menus, perfect for starting a workout or checking notifications on the go. The watch also now supports sleep apnea detection (in select regions), giving deeper insights into long-term health for those monitoring their sleep patterns.
Audio has received a noticeable upgrade as well. The improved speaker playback delivers louder and clearer sound, whether you’re taking calls or listening to music during a run. And for everyday convenience, Samsung Pay and smart home integration allow you to pay, control lights, or adjust your thermostat directly from your wrist.
Together, these updates make interacting with the Galaxy Watch Ultra feel smoother, smarter, and more intuitive, enhancing both fitness and daily life.
What’s Missing (SpO2, Dive App Improvements, etc.)
No smartwatch is perfect, and there are a few areas where the Galaxy Watch Ultra could improve:
- SpO2 Accuracy: Readings may vary depending on placement or movement
- Dive Mode: No dedicated scuba diving features; limited to swimming/snorkeling
- Samsung Phone Dependency: Some features, like advanced health insights and app integrations, work best with Samsung devices
Despite these small limitations, it remains a top-tier smartwatch for most users.
