What’s the Difference?

There are very few differences between the different generations of Amazfit Stratos. Each has a 316 stainless steel build with a plastic back. Meanwhile, Corning Gorilla Glass is used for the screen while the 1.34 inches display is powered by transflective memory-in-pixel (MIP).

All three watches have a touch-sensitive screen with two physical buttons for effortless navigation. So, you get almost similar build quality across all three.

In the fitness section, each of these three comes equipped with a heart rate sensor, accelerometer, inbuilt GPS, and geomagnetic sensors. This enables steps and calorie counting, 24/7 heart rate measurement, sleep tracking as well as the ability to map your routes and locations when you engage in an outdoor activity.

All three watches also come with a 4GB storage capacity that allows for onboard music storage. You can add your personal tracks to any of these three which you can listen to by connecting a Bluetooth headphone.

All three Stratos will also alert you when you receive a notification on your phone. You will need to enable notifications for your preferred apps in the companion app to be able to receive message alerts on the watch (the phone must be nearby).

So far, you can see that all three Amazfit Stratos have very similar features. Each of these three has got an outstanding design, while also being a comprehensive activity tracker with a decent long battery life.

Amazfit Stratos vs Stratos 2 vs Stratos 3
The Stratos 3 is the best choice

However, the Amazfit Stratos 3 features more preloaded sports modes. It features 80 preloaded sports modes compared to 16 on the other two. It also has more Firstbeat algorithms under the hood that enable advanced tracking and analysis during workouts. Moreover, the Stratos 3 has a slightly longer battery life than the other two. It has up to 7 days battery life compared to up to 5 days with Stratos 2 and 3. It’s clearly the best choice.

VERDICT: The Amazfit Stratos 3 being more equipped to track your active life, and has a longer battery life is no doubt the best choice.
