Garmin Forerunner 945 vs Apple Watch Series 4 vs Samsung Galaxy Watch Features compared

What’s the Difference?
  • Design

  • All three devices are premium choices with their respective sophisticated design that’s places these three on the high-end ladder.

    However, the Apple Watch Series 4 has the most innovative design, yet. With a moderate case size that’s smaller than the other two surprisingly has the widest display that allows you to see more at a glance.

    It’s also the sleekest while having the least weight which are attributes of a true fitness smartwatch that’s comfortable to wear all day long.

    Although, the 50 grams Forerunner 945 is also lightweight, thanks to the fiber-reinforced case. Unlike the Galaxy watch that’s quite heavy at 63 grams.

    The more interactive and lively AMOLED powers the display on both the Galaxy Watch and Series 4, but it can be hard to read under direct sunlight. Unlike the Transflective memory-in-pixel LED display of the 945 which isn’t as interactive as AMOLED is quite very easy to read outdoors.

    And this is one reason why the Forerunner 945 is the best choice for outdoor activities that allows you to catch a glimpse easily while on the go.

  • Cellular Connectivity

  • The Galaxy watch and Apple watch with cellular connectivity are standalone smartwatches which makes these two more comprehensive choices that gives your phone some rest.

    With these two, you can make and receive calls, and as well perform other functions that would have required your phone.

    The Forerunner 945 lacks this feature, and as a result, can’t initiate calls nor receive.

  • Fitness Tracking

  • These three are fitness focus considering the fitness tracking features and all the built in sensors. Each is well equipped to track your active life comprehensively.

    The Galaxy Watch offers 39 sport modes to choose from and can detect a good number of those, while the Apple watch series 4 also has a quite extensive list of fitness tracking features including the ECG tracking feature that can help in detecting atrial fibrillation – a form of irregular heart rhythm that can lead to heart problems.

    The Forerunner 945 being a GPS smartwatch features a full-color map with trendline popularity that helps you navigate the most difficult terrains.
    The Forerunner 945 also features a pulse ox sensor that comes handy for anyone who engages in acclimation activities.

    The pulse oximeter monitors your blood oxygen level while giving you insight on how your body is adjusting to higher heights. The 945 helps you know when it’s not safe to continue climbing.

  • Battery Life

All three devices have got a decent battery life, although the Series 4 isn’t all that impressive with about a day or two battery life. No thanks to the 1.78 inch AMOLED display.

The Galaxy Watch has quite a more impressive battery life that sees you through 2 days or more from a single charge, while the Forerunner 945 has the most impressive battery life that lasts about 2 weeks.

That’s a long battery life that tracks the most extreme workout sessions. A major reason it’s the best companion for your next exploration adventure.

Which is the Best?

All three contenders in this bout are outstanding choices – these three are undoubtedly some of the best smartwatches on the market right now.

However, the Apple Watch Series 4 with the most sophisticated design is the best choice for anyone using an iPhone.

On the other hand, the Galaxy watch that’s a more comprehensive smartwatch than the 945 is a great choice for Android users.

While Forerunner 945 with the longest battery life and an extensive list of fitness tracking features is the best choice for fitness tracking especially for professionals who want a comprehensive activity tracker that goes days on a single charge.

Here’s how they stack up;

Apple Watch Series 4 Has the most sophisticated design, while also being a comprehensive choice for fitness tracking. Its, the best choice for iPhone users,
Samsung Galaxy Watch A premium smartwatch with a decent battery life , and is also a great choice for comprehensive fitness tracking.
Garmin Forerunner 945 The best choice for fitness tracking with the longest battery life featuring full color map with trendline popularity.

Our Pick

The Galaxy Watch is half the price of the Forerunner 945, it however is a standalone smartwatch with a decent battery life while also being a great choice for tracking your daily activities. And being compatible with both Android and iPhone makes it a great bargain.
We pick the Samsung Galaxy Watch.
