Amazfit T Rex 2 vs Galaxy Watch 4: Which One Performs the Best?

Amazfit T Rex 2 vs Galaxy Watch 4

Being a name that’ll echo throughout history for coming up with smartwatches that combine premium quality with super-rugged, outdoor-oriented features, Amazfit has gathered a mass following after their successful range of smartwatches. And now, the Amazfit T-Rex 2 is here to take the reputation to the next level, bringing with it new and exciting features.

Amazfit T Rex 2 vs Galaxy Watch 4

How does it compete with the gold-standard Smartwatch from Samsung, the Galaxy Watch 4? We will be comparing these two watches head-on to help you decide which one you should go for.

Design and Material

The Amazfit T-Rex 2 was designed with outdoor enthusiasts such as rock-climbers, surfers, and sky-divers in mind, and was designed to complement such lifestyle. In terms of build, just by looking at it, you can tell that this watch can take one hell of a beating. It’s made from Polymer alloy, which will more than protect this watch from accidental drops and knocks and preserve its integrity. It comes with ATM10 water-resistant, which means not only you can rock this watch while being out in the rain or washing your hands, you can even take it to swim at both the pool and the sea.

And from Samsung, we embrace an old, familiar yet different feeling with their Galaxy Watch 4. Being true to the signature Galaxy Lineup Aesthetics, the Galaxy Watch 4 looks comparatively sharper and more sophisticated, in manner. The watch also features materials like a stainless steel case, leather straps, and a rotating bezel. The T-Rex 2 comes with two physical buttons on either side of the watch face that replicates the intuitive touchscreen controls, making this watch ideal for operating when wearing gloves. The thick bezel should help somewhat to keep the glass from scratches. The watch also comes with a rotating bezel, which only adds to the visual appeal. Galaxy Watch 4, on the other hand, comes with a uniform set of crown buttons with an oblong shape, paying a small tribute to their predecessors.


With the T-Rex 2, the always-on 1.39” display makes a comeback from the T-Rex Pro with a plethora of designs depending on the watch face you’re using, giving the watch a variety of options to choose from, and all of them suit the overall rugged aesthetics. The screen also comes with a peak of 1000 nits of brightness. On the other hand, the Galaxy Watch 4 brings its signature 1.4 inches, Super AMOLED, always-on display with Corning Gorilla Glass DX+ protection. Therefore, if you want to go full eye candy, you should go for the Galaxy Watch 4. If you prefer protection, our money’s on T-Rex 2.

Fitness Features

With the T-Rex 2, fitness is the primary concern. With an updated PPG Heart Rate Sensor, the T-Rex 2 can measure blood oxygen and stress levels. In terms of location, the watch comes with a dual-band, five-satellite GPS, a compass, and a barometric altimeter for giving you accurate data regarding your location. And if you get lost, no worries, cause the watch comes with a direct return function. In terms of sports, you’ll be able to keep tabs on over 150 different sports and activities such as running, cycling, swimming, strength training, etc. There is also support for events like snowboarding, skiing, and such!

The Galaxy Watch 4 packs a brand-new health sensor for the Galaxy Watch 4 and combines heart-rate monitoring, ECH, and BIA for a 3-in-1 sensor that sits relatively closer to your wrist, providing more accurate results. The sensor provides accurate data regarding your heart rate, blood oxygen levels, and overall body composition, making this the first-ever smartwatch to do so. With this body composition measurement, you’ll be able to see key stats of your body, such as skeletal muscle mass, and body fat percentage, all of which are easy to run, but you do have to remain still through the process, although in order to get the proper experience, you need to be connected to a Samsung smartphone because of the limited compatibility of some fitness features.


However, in terms of runtime, the 44mm Galaxy Watch 4 is powered by a 361mAh battery and gives us a runtime of roughly two days from a single charge. Please note we showed no mercy on the battery and used it as much as we could, tinkering with every possible feature. From that alone, you can be confident about the watch lasting for a full three days on basic use. However, on the 40mm version, you’ll be getting a smaller battery, so expect a smaller battery life. 

On the other hand, the Amazift T-Rex 2’s battery won’t let you down either since it comes packing an above-average 500mah cell, which, if used with nothing but the basics, will last you up to a total of 24 days! Even if you are utilizing all the features and with an always-on screen enabled, we squeezed around 10 days of use without needing to recharge. Then again, if you want to squeeze even more runtime, the “extreme battery saver mode” will last you around 45 days if you’re planning to be out of the grid.

Our Takeaway

So basically, if you’re in the market for an overall rugged, durable, long-lasting smartwatch that won’t let you down in terms of performance and activity, the Amazfit T-Rex 2 would be the perfect choice for you. But on the other hand, if you’re knee-deep into the Samsung Ecosystem and want the best out of your Samsung phone along with solid software and fitness experience, the Galaxy Watch 4 is the right choice for you.
