In the Android wearable scene, the Samsung Galaxy Watch 4 is regarded as the smartwatch to beat, and for good reason. After all, it offers a ton of health and fitness tracking, smart features and solid durability. However, that doesn’t automatically mean it’s the only option. Take the Amazfit GTR 3 Pro, for instance. It has a longer battery life and iOS support, and it doesn’t exactly lag behind in general.Â
On that note, it’s the GTR 3 Pro vs. Galaxy Watch 4 for most folks looking for a feature-packed smartwatch for daily use. And to help you figure out which one is best for you, we compare the two across a few key aspects.

Design and Display
The Samsung Galaxy Watch 4 comes in 40mm and 44mm sizes, while the Amazfit GTR 3 Pro is available only in 46mm.
Both smartwatches share a similar form factor in that they have a circular display that’s reminiscent of a traditional wristwatch. However, only the GTR 3 Pro has a physical crown as an additional navigation method. That’s as opposed to the two-button setup on the Galaxy Watch 4.
Whereas the GTR 3 Pro only comes in a case size of 46mm, the Galaxy Watch 4 offers 40mm and 44mm options. That extra choice makes it more flexible to cater to users with smaller wrists. Accordingly, the GTR 3 Pro measures 46mm x 46mm x 10.7mm and weighs 32g. Meanwhile, the Galaxy Watch 4’s 44mm variant is at 44.4mm x 43.3mm x 9.6mm and 30.3g, and the 40mm is at 40.4mm x 39.3mm x 9.7mm and 25.9g.
As for their displays, the GTR 3 Pro has a 1.45-inch 480 x 480 AMOLED touchscreen. It’s topped with tempered glass that features anti-fingerprint coating, which gives it somewhat of an edge here. The 44mm Galaxy Watch 4 sports a 1.36-inch 450 x 450 Super AMOLED with full-color always-on display and Corning Gorilla Glass DX+. The 40mm model uses the same hardware, but it has a smaller 1.19-inch 396 x 396 touchscreen. At any rate, all of them are as sharp as the other, clocking in at roughly 330 PPI.
Both have a 5 ATM water resistance rating, but only the Galaxy Watch 4 is officially rated as IP68 and meets the MIL-STD-810G drop test standard.
Fitness and Health Tracking
While only the Amazfit GTR 3 Pro measures temperature and breathing rate, only the Samsung Galaxy Watch 4 monitors blood pressure and features ECG and body composition analysis.
First off, the GTR 3 Pro has more than 150 sports modes. That means there’s a good chance that you can track just about any activity, regardless of how specific or random it may be. Comparatively, the Galaxy Watch 4 comes with over 90 presets right from the get-go. For the record, both have built-in GPS, so you don’t have to bring your phone along with you when going out for a run.
Speaking of, the Galaxy Watch 4 sets itself apart by offering advanced insights on running and cycling. For instance, runners can get metrics such as stiffness, contact time and asymmetry. That includes feedback to help them figure out whether they need to work on their form or not.Â
As for health-related monitoring, it’s a bit of a mixed bag. Both have the usual features you’d expect from any smartwatch worth its salt. In other words, they can monitor heart rate, blood oxygen and sleep, among other things. Notably, the GTR 3 Pro can measure body and ambient temperatures and breathing rate, the latter of which is unusual for fitness trackers. On the other hand, the Galaxy Watch 4 has the edge with its body composition analysis. Moreover, it has ECG and blood pressure monitoring, but their functionality is limited to certain regions.Â
Battery Life and Connectivity
The Amazfit GTR 3 Pro beats the Samsung Galaxy Watch 4 in battery life.
Straight from the horse’s mouth, Samsung says the Galaxy Watch 4 is good for up to 40 hours on a single charge. Granted, there are a lot of factors involved that can affect overall battery life, so performance will vary individually more often than not.
Now this is where the GTR 3 Pro shines. According to Amazfit, it can go up to 12 days, and that’s thanks to its more energy efficient Zepp OS, as opposed to Wear OS. In battery saver mode, it’s rated for up to 30 days, and with heavy usage, it can last up to six days. To no one’s surprise, battery life dwindles to 35 hours in GPS mode.
Connectivity-wise, both are running on Bluetooth 5.0. And while the GTR 3 Pro only has 2.4GHz Wi-Fi, the Galaxy Watch 4 comes out on top with not only 2.4GHz support but also 5GHz.

Other Features and Software
The Samsung Galaxy Watch 4 provides a better user experience and a wider selection of apps than the Amazfit GTR 3 Pro.
As noted, the GTR 3 Pro is powered by Zepp OS, while the Galaxy Watch 4 uses Wear OS 3 with Samsung’s One UI Watch 3 skin. Without going into too much detail, one of the most important takeaways here is that the latter has access to the Google Play Store and the huge library of apps it has to offer.
That said, the GTR 3 Pro’s Zepp app has one huge advantage: it’s compatible with Android and iOS. That makes it more flexible and appealing to a wider audience (i.e., iPhone users and Android smartphone owners). The Galaxy Watch 4’s app is the Galaxy Wearable, and it’s unfortunately exclusive to Android. Its iOS equivalent is the Samsung Galaxy Watch app, but support only goes up to the Galaxy Watch 3.
For those who like exercising outdoors while listening to some tunes, the good news is both smartwatches have offline music playback. The bad news is the GTR 3 Pro can only play locally stored media, which may not be a deal breaker for some. However, that means it doesn’t support third-party options. In the Galaxy Watch 4’s case, you can store tracks internally or download and save content from apps like Spotify and YouTube Music.

Verdict
In our opinion, the Amazfit GTR 3 Pro can serve as a daily driver, particularly because of its battery life, but it can’t really hold a candle to the Samsung Galaxy Watch 4.
By all means, the Amazfit GTR 3 Pro is decent with a good price-to-performance ratio. However, it’s like a basic fitness tracker repackaged as a smartwatch with a couple of features to match. It does have a lot going for it, including a long battery life, over 150 sports modes and Android and iOS compatibility. On top of that, it has uncommon features such as breathing rate monitoring, but it’s just not as polished as its counterparts from other brands.
In comparison, the Samsung Galaxy Watch 4 is a beaut with its vibrant display, and it’s solid to boot (read: IP68 and MIL-STD-810G). From a fitness perspective, it’s more comprehensive too, as it offers advanced metrics for certain workouts. In a similar fashion, its health-related features go beyond the usual with blood pressure monitoring, ECG and body composition analysis. What’s more, it has more app variety because of its access to the Play Store. All in all, it offers a more refined user interface and experience.
