Quick Overview

A detailed comparison between the Apple Watch Series 9 and Series 8, covering design, performance, features, health tracking, battery life, pros, and cons.
## Apple Watch Series 9 vs. Apple Watch Series 8: Detailed Comparison

Choosing between Apple Watch Series 9 and Series 8 can be a tough decision, especially since they share a similar design and price. To help you make the right choice, here’s a detailed comparison.

Design and Display

At first glance, the Apple Watch Series 9 and Series 8 look almost identical. They share the same sleek design, comfortable fit, and solid build. However, the Series 9 boasts a significantly brighter display - up to 2000 nits. This makes a noticeable difference when using the watch outdoors, especially on sunny days. While jogging in bright sunlight, the Series 9 was much easier to see, which we found to be a small but significant improvement over the Series 8.

Performance and Features

The Apple Watch Series 9 is powered by the new S9 chip, which has noticeably improved performance. Apps open faster and the overall experience is smoother. Another major improvement is Siri, which has been improved on the Series 9. It responds faster and more reliably, even without a strong internet connection. Setting timers and reminders is also much faster on the Series 9. The new ultra-wideband chip in Series 9 provides accurate iPhone search and AirTags.

The Series 8 still offers great performance, but without these improvements. It uses an older chip that still performs well, but not as fast as the S9.

One of the most talked about features of the Series 9 is the double-tap gesture. It allows users to control the watch by simply tapping it with their thumb and index finger. While innovative, I found the gesture to be a bit awkward and not always reliable. So far, it’s not a game changer, but it has potential. The Series 8 lacks this feature, so the Series 9 is the only option if you’re intrigued.

Health & Fitness

Both models have extensive health monitoring capabilities, including heart rate tracking, blood oxygen level monitoring, and fall detection. The Series 8 also has a temperature sensor to help track your menstrual cycle and predict ovulation. However, the Series 9 has some lagging features, such as processing health data using Siri on the device.

As for fitness tracking, both watches are excellent, offering customizable workouts and detailed metrics. I’ve used both devices for running and hiking and they performed well.

Battery life

Battery life is one area where the watches are similar: both the Series 9 and Series 8 have a battery life of about one day with normal use and need to be recharged daily. The Series 9 is slightly more power efficient, but the significant improvement in battery life didn’t translate into a significant improvement. It didn’t result in a significant improvement in battery life. The battery has to be charged every night, especially if it’s used for sleep tracking. Fast charging is useful, but the battery should last longer.

Pros and Cons of Apple Watch Series 9

  • Plus:
    • Faster S9 chip: Better overall performance and Siri responsiveness.
    • Significantly brighter display for better outdoor visibility.
    • New ultra-wideband chip: Provides accurate iPhone search and AirTags.
    • Siri processing on the device: Faster and more reliable response.
    • Dual Touch Gestures: Provides convenient one-handed control (where available).
    • Carbon neutral design: Environmentally friendly choice.
  • Cons:
    • Significant iterative updates: No major leap over the Series 8.
    • Double tap functionality: Not available at launch and limited customization.
    • Siri offline functionality: Limited to basic tasks like setting timers.
    • Battery life: Same as previous models.
    • Some new features: Siri health processing on the device is delayed, for example.
    • Design: Almost identical to the previous generation.

Apple Watch Series 8

  • Benefits:
    • Fast charging: Provides fast power on.
    • Always-on display: provides easy access to information.
    • Advanced fitness tracking: with customizable workout and heart rate zones.
    • Comprehensive health monitoring: includes heart rate, blood oxygen and temperature measurements.
    • Seamless iPhone integration: for notifications, calls and Apple Pay.
    • Rugged construction: crack-resistant, dustproof and waterproof.
  • Cons:
    • Temperature sensor data: Not all users may find it immediately available or useful.
    • Battery life: Under normal use does not exceed one day and requires daily recharging.
    • Aluminum screen: Easy to scratch and requires the use of a screen protector.
    • Fewer new features compared to Series 7.
    • Digital crown: Can malfunction and cause unintentional volume changes.

Real-world use

In my experience, the Series 9 is an improved version of the Series 8. The brighter display is a welcome improvement, and the improved performance is noteworthy. The precision search feature is surprisingly useful, and the improved Siri is definitely a plus. However, the double-tap feature is still to be finalized, and battery life remains limited.

On the other hand, the Series 8 is a solid device with all the basic features you’d expect from an Apple Watch. It’s a solid device that integrates seamlessly into the Apple ecosystem.

Final Thoughts

If you’re upgrading from an older Apple Watch, the Series 9 is worth the upgrade, as the performance and display have improved markedly. However, if you already have a Series 8, it may not be worth upgrading your watch unless you’re interested in new features like precision search or double-tap gestures. The Series 8 remains a great option, especially if you can find it at a discounted price. Ultimately, the best choice depends on your individual needs and priorities.
