The Ultra 2 demonstrated notable heart rate accuracy, achieving correlation scores of 0.99 for indoor cycling and 0.98 for running, making it a standout in controlled conditions. In contrast, the Galaxy Watch 9 encountered limitations, such as battery performance that hindered its ability to complete certain tests, highlighting a key area for improvement.
Dive into the Ultra 2’s GPS reliability, which positions it as a strong option for outdoor activities and examine the Galaxy Watch 9’s GPS, which remains untested in this review. Learn about their sleep tracking capabilities, where both devices show moderate accuracy but face challenges with light sleep detection. Finally, understand how battery life impacts usability, with the Ultra 2 offering longer endurance compared to the Galaxy Watch 9, which may fall short for users with high daily demands.
Galaxy Watch 9 vs Ultra 2
TL;DR Key Takeaways :
- The Galaxy Watch Ultra 2 and Galaxy Watch 9 excel in heart rate tracking, with the Ultra 2 achieving exceptional accuracy during physical activities (correlation scores up to 0.99).
- Sleep tracking performance is moderate, with reasonable accuracy for deep and REM sleep but less reliable results for light sleep and a tendency to overestimate sleep durations.
- The Galaxy Watch Ultra 2 outperforms in GPS functionality, maintaining accuracy in challenging environments, while the Galaxy Watch 9’s GPS capabilities remain untested due to battery issues.
- Battery life is a key differentiator, with the Ultra 2 offering superior endurance for continuous monitoring, whereas the Galaxy Watch 9 struggles with demanding use cases.
- Overall, the Ultra 2 is better suited for users with high-performance needs, while the Galaxy Watch 9 may appeal to those with less intensive requirements, though further testing is needed for a complete evaluation.
Heart Rate Tracking: A Strong Contender
The Galaxy Watch Ultra 2 and Galaxy Watch 9 deliver noteworthy accuracy in heart rate tracking, particularly during physical activities. The Ultra 2 demonstrated exceptional precision, achieving correlation scores of 0.99 for indoor cycling, 0.98 for outdoor cycling, and 0.98 for running. Similarly, the Galaxy Watch 9 performed well, with a 0.99 correlation for indoor cycling and 0.96 for outdoor cycling. However, its running performance remains inconclusive due to battery limitations encountered during testing.
These results position both devices as reliable options for fitness enthusiasts who prioritize accurate heart rate monitoring. Their performance surpasses many competitors in the market, making them appealing choices for users focused on tracking health and performance metrics during workouts or daily activities.
Sleep Tracking: Moderate Performance
Sleep monitoring is a critical feature for many smartwatch users and the Galaxy Watch Ultra 2 and Galaxy Watch 9 offer mixed results in this area. Both devices demonstrated reasonable agreement with reference data for deep sleep (81%-86%) and REM sleep (69%-76%). However, their tracking of light sleep was less accurate, with agreement rates ranging between 48% and 51%. Additionally, both watches tended to overestimate the duration of deep and REM sleep, which may skew the overall sleep analysis.
While these devices provide valuable insights into sleep patterns, users seeking highly precise data may find the results less satisfactory. For casual users, the information provided can still serve as a helpful tool for understanding general sleep trends and making lifestyle adjustments.

GPS Tracking: A Tale of Two Watches
The Galaxy Watch Ultra 2 excels in GPS performance, particularly in challenging environments where signal obstructions are common. This makes it a reliable companion for outdoor activities such as running, hiking and cycling. Its ability to maintain accuracy in such conditions sets it apart as a dependable choice for users who prioritize location tracking.
In contrast, the Galaxy Watch 9’s GPS capabilities remain untested due to battery issues encountered during initial trials. This leaves a gap in understanding its potential for outdoor navigation and activity tracking. For now, the Ultra 2 emerges as the preferred option for users who require precise GPS functionality, while further testing is needed to evaluate the Galaxy Watch 9’s performance in this critical area.
Battery Life: A Key Differentiator
Battery life is a crucial factor for wearable devices and the Galaxy Watch Ultra 2 outshines the Galaxy Watch 9 in this regard. The Ultra 2 demonstrated consistent performance during extended use, including sleep tracking and fitness activities, making it a reliable choice for users who require continuous monitoring throughout the day and night.
On the other hand, the Galaxy Watch 9 struggled to last through a full night of sleep tracking and a morning run, highlighting a significant limitation for users with demanding needs. For those who rely on their smartwatch for long-lasting performance, the Ultra 2 offers a clear advantage, while the Galaxy Watch 9 may be better suited for users with less intensive requirements.
Overall Performance: Promising with Areas for Improvement
The Galaxy Watch Ultra 2 and Galaxy Watch 9 represent notable advancements in Samsung’s wearable lineup, offering a range of features designed to enhance fitness and health tracking. Both devices excel in heart rate monitoring, with the Ultra 2 also standing out for its robust GPS performance and superior battery life. However, their sleep tracking accuracy leaves room for improvement and the Galaxy Watch 9’s battery limitations and untested GPS capabilities highlight areas that require refinement.
For users with demanding needs, the Ultra 2 emerges as the more reliable choice, offering endurance and precision for outdoor activities and continuous monitoring. Meanwhile, the Galaxy Watch 9 may appeal to those with less intensive requirements, though its limitations could be a drawback for some. As additional testing is conducted, a clearer understanding of their capabilities will help users make informed decisions about which device best aligns with their lifestyle and priorities.
