Enhanced Health Tracking Capabilities
One of the most significant improvements in the Apple Watch Series 9 is its more accurate and sensitive health tracking capabilities. This upgrade is primarily due to the new S9 chip, which enhances the watch’s ability to process data from its various sensors.
More Accurate Workout Detection
During our two-month testing period, we found that the Series 9 consistently outperformed the previous generation Apple Watch Ultra in detecting and prompting workouts. The Series 9 would often trigger workout prompts earlier and more accurately, sometimes detecting activities that the older model missed entirely.
Improved Heart Rate Monitoring
A common issue with previous Apple Watch models was the occasional loss of heart rate tracking during vigorous workouts. This problem often required users to tighten their watch bands uncomfortably to maintain contact. The Series 9 demonstrated a marked improvement in this area, maintaining consistent heart rate tracking even during intense activities without the need for band adjustments.
Calorie Tracking Discrepancies
Our testing revealed significant differences in calorie tracking between the Series 9 and older models. Here’s a comparison of calorie burn data from various activities:
| Workout Type | Series 9 (2023) | Ultra (2022) |
| Indoor Cycling | 173 CAL | 309 CAL |
| Elliptical | 158 CAL | 221 CAL |
| Outdoor Walk | 241 CAL | 255 CAL |
| Strength Training | 60 CAL | 75 CAL |
These discrepancies, often showing lower calorie counts on the Series 9, suggest that the new model may be providing more accurate data. This improvement in accuracy could have implications for users relying on their Apple Watch for fitness and weight management goals.
Display and Visibility Enhancements
The Apple Watch Series 9 features a significant upgrade in display brightness, doubling from 1000 nits to 2000 nits. This enhancement greatly improves the watch’s visibility in bright outdoor conditions, making it easier to read during activities like running, cycling, or hiking.
Conversely, the display can now dim to as low as 1 nit, which helps conserve battery life when using the always-on display feature. This range of brightness allows the Series 9 to adapt to various lighting conditions more effectively than its predecessors.
Battery Life Improvements
Despite the brighter display and more powerful processor, the Apple Watch Series 9 demonstrates impressive gains in battery life. While Apple officially rates the battery life at 18 hours (the same as the Series 8), our real-world testing revealed significantly better performance.
On typical days with multiple workout tracking sessions and continuous use of the always-on display, the Series 9 often ended the day with 60% battery remaining. This is a notable improvement over the Series 8, which usually had 30-40% battery left under similar conditions.
These battery life enhancements make the Series 9 more practical for sleep tracking, as users can quickly charge the watch for 30-40 minutes before bed and have enough power to last through the night.
New Double-Tap Gesture
The Apple Watch Series 9 introduces a new double-tap gesture, enabled by the advanced S9 processor. This feature allows users to perform certain actions by tapping their thumb and forefinger together twice. While currently limited to activating the primary action in open apps, it significantly improves one-handed operation of the watch.
For example, users can answer phone calls, stop timers, or control music playback without needing to touch the screen. This gesture is particularly useful in situations where the user’s hands are occupied or dirty.
Who Should Buy the Apple Watch Series 9?
The Apple Watch Series 9 is an excellent choice for several types of users:
- First-time smartwatch buyers: The Series 9 offers a comprehensive set of features and the latest technology, making it a great entry point into the Apple Watch ecosystem.
- Upgraders from Series 6 or earlier: Users with older Apple Watch models will see significant improvements in performance, health tracking accuracy, and battery life.
- Health and fitness enthusiasts: The enhanced accuracy of health sensors makes the Series 9 a compelling choice for those who prioritize detailed health and fitness tracking.
- Outdoor activity lovers: The brighter display makes the Series 9 more usable in sunny conditions, benefiting runners, cyclists, and hikers.
Areas for Future Improvement
While the Apple Watch Series 9 represents a significant step forward, there are still areas where future models could improve:
- Stress tracking using HRV: Although the Apple Watch measures Heart Rate Variability (HRV), it doesn’t currently offer native stress tracking features. Implementing this could provide valuable insights into users’ mental health.
- Blood pressure monitoring: Adding a blood pressure sensor could help users track and manage hypertension more effectively.
- Blood glucose sensing: Non-invasive blood glucose monitoring would be a game-changer for diabetes management and general health insights.
Conclusion
The Apple Watch Series 9 represents a significant leap forward in Apple’s smartwatch technology. Its improved health tracking accuracy, enhanced display, better battery life, and innovative features like the double-tap gesture make it a compelling upgrade for many users. While there’s still room for improvement in areas like stress tracking and additional health sensors, the Series 9 solidifies the Apple Watch’s position as a leader in the smartwatch market.
For those in the market for a new smartwatch or considering an upgrade from an older model, the Apple Watch Series 9 offers a blend of cutting-edge technology and refined user experience that’s hard to beat. Its ability to more accurately track health metrics and perform in various conditions makes it an invaluable tool for both everyday use and fitness enthusiasts alike.
