The Samsung Watch 4 is the smartwatch to beat in the Android wearables scene, and for good reason. After all, it has a lot of ways to track your health and fitness, a lot of smart features, and is built to last. But that doesn’t always mean that it’s the only choice. Take, for example, the Amazfit GTR 3 Pro.
It has a longer battery life, works with iOS, and doesn’t really fall behind in other ways. So, for most people who want a smartwatch with lots of features for daily use, the choice is between the GTR 3 Pro and the Galaxy Watch 4. And to help you decide which one is best for you, we compare them in a few important ways.

Amazfit GTR 3 Pro vs Samsung Galaxy Watch 4: Design and Display

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. You can buy this smartwatch from its official website.
Amazfit GTR 3 Pro vs Samsung Galaxy Watch 4: Health & Fitness
Smartwatches have optical biometric sensors that can measure blood oxygen and heart rate. With the biotracker 3.0 ppg sensor, the gtr3 pro has a really cool one-tap measurement feature that measures blood oxygen, heart rate, breath rate, and stress levels in 45 seconds. We think this is pretty cool.
Samsung’s Galaxy Watch 4 has a number of health and fitness features, such as GPS tracking, an optical heart rate sensor, and ECG monitoring. The 3-in-1 BioActive Sensor is a new part of this watch. It lets it track your heart rate, blood oxygen levels, and body composition. You can buy this smartwatch from its official website.
Amazfit GTR 3 Pro vs Samsung Galaxy Watch 4: Software

When it comes to software, the GTR 3 Pro is great because it works with both iPhone and Android devices. This is made possible by Zapp OS, which can be easily set up by downloading the Zapp app from the App Store and the Google Play Store.
The galaxy watch 4 has one UI on top of google’s wear os, but it pairs with the galaxy wearable app instead of the wear os app, which isn’t available on iOS. This makes the gtl3 pro a more versatile smartwatch if you ever want to switch to a different device. Fitness data is saved well in the zap app, and you can sync it to Strava, Google Fit, and Apple Health.
Amazfit GTR 3 Pro vs Samsung Galaxy Watch 4: Battery Life and Connectivity
Samsung says the Galaxy Watch 4 can last up to 40 hours on a single charge. Even so, there are a lot of things that can affect how long a battery lasts as a whole, so individual performance will usually vary.
Here’s where the GTR 3 Pro really stands out. According to Amazfit, it can last up to 12 days. This is because Zepp OS uses less power than Wear OS, which is why it can last longer. In “battery saver” mode, it can last up to 30 days, and if you use it a lot, it can last up to 6 days. In GPS mode, the battery only lasts 35 hours, which doesn’t surprise anyone.
Which one should you buy?
Both smartwatches are really cool, so it’s hard to choose between them. But the Amazfit GTR 3 pro is a great fitness smartwatch that does the basics very well. It is a clear choice if you’re serious about tracking your fitness levels but don’t want to be limited by the features of fitness trackers and the complexity of a full-fledged smartwatch.
We’re not saying the Galaxy Watch 4 is a bad product, but it is more of a companion for your Samsung phone and doesn’t track fitness as well as the GTR 3 Pro. Also, the price of the Amazfit GTR 3 pro is less than that of the Galaxy Watch 4.
