Design and Features Comparison

The Fenix 8 and Forerunner 965 stand out with their unique builds, advanced tracking tools, and smart extras—let’s explore which suits your needs best.
Design Differences: [Fenix 8 Vs. Forerunner 965] has a more premium metal design
Fenix 8 feels sturdy with its premium metal design. It includes a metal plate, which adds durability and style. I noticed it fits well for multi-sport use. Its materials increase the price but make it worth considering for outdoor workouts.
Forerunner 965 lacks this metallic look and build. It opts for lighter materials instead of metal finishes. While both are fitness trackers, Fenix 8 clearly stands out in terms of toughness and aesthetics.
Activity Tracking: Similar features for both wearables
Both wearables support running, cycling, swimming, and triathlons. I find their tracking very accurate for steps, calories burned, and physical exercise.
Each device tracks sleep patterns and resting heart rate nonstop. Both use a heart rate monitor, accelerometer, gyroscope, barometric sensor, and GPS for precision workouts.
Battery Life: [Fenix 8 Vs. Forerunner 965] has longer battery life
The Fenix 8 offers longer battery life. It lasts nearly 26 hours during a marathon, making it great for long usage. Its solar edition boosts performance with improved solar panels.
This makes the Fenix 8 stand out as a reliable smartwatch.
The Forerunner 965 falls short in this area but still performs well. Yet, compared to the Fenix 8, its battery power is less impressive for extended activities. The Fenix’s strong solar battery gives it an edge over other wearables, especially outdoors or during heavy use!
Additional Features: [Fenix 8 Vs. Forerunner 965] has diving mode, speaker, and microphone
Fenix 8 has a diving mode, which works like a mini dive computer. I find this feature helpful for tracking air pressure and monitoring depth while underwater. It’s designed well for activities like wakesurfing or kiteboarding too.
It also includes both a speaker and microphone, making phone calls easy without an iPhone or Android device in hand. This setup pairs with smartphones using Bluetooth Smart, so there’s no need to carry extra gadgets.
The convenience of these tools saves time during workouts and daily tasks alike.
Potential Features for Forerunner 965
The Forerunner 965 could gain features like advanced navigation tools or a built-in compass to match other premium devices. Adding these updates would improve daily use and fitness tracking for its users.
Possible features from [Fenix 8 Vs. Forerunner 965] that could be added to Forerunner 965 to bridge the gap
I see room to add wireless charging. It would be easier than using a charging pad or cables. Many smartphones and devices, like some tablets and smartwatches, already have this tech.
It could make daily use better for users.
Adding Gorilla Glass for stronger screens makes sense. Devices like iPhones and Android gadgets rely on it for durability. A compass upgrade or ECG monitoring might improve navigation and health tracking too.
These features fit well with global positioning systems already in place on the watch.
Benefits for users of having these added features.
New features, like diving mode in the Forerunner 965, open up more options for water sports lovers. A speaker and microphone make hands-free calls easy during workouts or busy moments.
With longer battery life, users can rely on their devices for marathons or long hikes without worry. Detailed running metrics help track VO2 max and improve training plans for serious athletes.
Conclusion
The Fenix 8 and Forerunner 965 both stand out. They each bring strong features to the table, but they serve different needs.
The Fenix 8 costs more, starting around $1,000. Its metal design feels premium in hand. It also adds a speaker and microphone for calls. This watch is best for someone who values style along with performance.
On the other hand, the Forerunner 965 offers great value at about $600 or less on sale. It has similar tracking abilities as the Fenix 8. Plus, it boasts longer battery life and some unique options like diving mode.
I would recommend going with the Fenix 8 if you want high-end materials and advanced extras like phone-call support through your wearable device. Its quality justifies its higher price tag if budget isn’t an issue.
Both watches share strengths in activity tracking and training analysis accuracy but choosing one depends on your priorities—style or savings? You get solid wireless technology features either way!
