Samsung’s Galaxy Watch 9 and Ultra 2: A Year of Refinement

Announced today, these wearables are focused on enhancing the features that users love while addressing past weaknesses, particularly in battery life and preventive health features.

Galaxy Watch Ultra 2: Key Upgrades

The Galaxy Watch Ultra 2 comes with a price tag of $699.99, which is a $50 increase over its predecessor. One of the most notable improvements is its battery, which has been upgraded to an impressive 800mAh, a 35 percent increase compared to the 590mAh battery in the original Ultra. In real-world usage, this could translate to approximately 70 hours of performance based on past experiences with the original model. Interestingly, the Ultra 2 is also 12 percent thinner with a case measuring just 10.7mm, despite the larger battery capacity. Additionally, the standard strap has been made about 1mm thinner and offers a softer feel against the skin.

Enhanced Display for Outdoor Use

For outdoor enthusiasts, the Ultra 2 now features an astonishing 5,000-nit display, significantly brighter than the 3,000-nit display of the Galaxy Watch 9. This enhancement improves visibility in direct sunlight, making it one of the brightest smartwatch screens available. Observations from colleagues highlight that the display’s brightness surpasses that of previous models, which should please users who enjoy outdoor activities.

For fitness enthusiasts, the Ultra 2 also adds a trail run tracking feature designed to enhance navigation during outdoor activities. It allows users to download GPX files for real-time navigation and elevation guidance, predicting hydration needs based on workout intensity. Additionally, it carries an IP69K and 10 ATM rating for water resistance, catering to divers with a bespoke app from Mares that will monitor descent speed and provide ascent guidance.

Galaxy Watch 9: Incremental Updates

Meanwhile, the Galaxy Watch 9 sees a modest price increase to $379.99. This model largely mirrors the design and functionality of the Galaxy Watch 8, but it swaps Samsung’s proprietary Exynos chipset for Qualcomm’s Snapdragon Wear Elite. This change aims to boost power efficiency and AI processing capabilities, which could help improve performance with the new Wear OS 7 updates, permitting more seamless interaction without needing the wake word for voice activation.

The Watch 9 also benefits from slight battery capacity increases across both sizes. The 40mm model receives a 20 percent bump to a 390mAh battery, while the larger 44mm version increases from 435mAh to 445mAh. Notably, new “air pocket structure” straps weigh 17 percent less and are designed to be more comfortable and breathable.

New Preventive Health Features

Both the Galaxy Watch 9 and Ultra 2 introduce four new preventive health metrics. A significant addition is the Vitals feature, which gathers baseline metrics for blood oxygen, heart rate, skin temperature, and more after a week of continuous wear. Users receive alerts if any of these metrics diverge from their baseline, along with tips for improvement.

They will also feature a Heart Health Score and a Daily Cardio Load metric. The Heart Health Score evaluates daily health based on sleep and activity, while the Daily Cardio Load assesses training intensity and recovery needs. These features echo similar innovations by brands like Oura and Fitbit.

Unique to this generation is the new Fitness Index, which compares users’ physical metrics against those of other Samsung users, showcasing strengths and areas for improvement similar to role-playing game radar charts.

Conclusion

Samsung’s latest smartwatch offerings reflect a concerted effort to refine existing features while catching up with competitors in the health tech space. However, higher price points may deter some buyers as the market continues to evolve. Preorders start today, with shipments expected from August 7th.
