The Samsung Galaxy Watch Active 2 comes in two sizes; the smaller 40mm and the bigger 44mm. Both have the same features except for the slight differences in the size and battery life. Recall that the Galaxy Watch Active 2 which is now succeeded by the Galaxy Watch 4 is a very compact smartwatch that’s equally equipped with a great number of features. In this post, we take a look at the differences between the Samsung Galaxy Watch Active 2 (40mm) vs (44mm) to help you make the right choice.
The 44mm and 40mm are basically the same in all almost every aspect. The only difference between these two is the size, weight and battery life. Beyond these, both watches are the same.
Note that the 40mm and 44mm are both available in LTE and Bluetooth models. The difference is that the LTE model comes with an eSIM that enables cellular connectivity which enables it to make and receive calls independent of a smartphone. As a result, the LTE model is a standalone smartwatch. The Bluetooth model requires your phone nearby to make and receive calls and receive and reply to messages.

Before we continue, you should know that Active 2 is one adorable smartwatch with a lot of features. It comes in a compact and slim aluminum frame paired with removable silicone straps. The AMOLED-powered display is rich in colors and very pleasing to watch. Navigation is a bliss with two physical buttons, a touch-sensitive screen, and a digital rotating bezel.
It’s fitness-focused, perhaps one of the best fitness smartwatches. It’s equipped to track your steps, calories, stress, sleep, heart rate, and many more features. It can also help you manage blood pressure and features ECG measurement. There are lots of workout modes and it can detect hard falls.
Onboard is about 3GB of storage capacity that allows you to add your favorite tracks to the watch. And with a microphone and speaker, you can make and receive calls when your phone is nearby (the LTE model doesn’t need your phone to make and receive calls).
When notification is enabled, the Active 2 will alert via a ringtone or vibration depending on settings. You can reply to messages with your voice, emojis, preset quick replies, or type it directly using the built-in Samsung keyboard.
In all, the Galaxy Watch Active 2 is an outstanding smartwatch that comes in two sizes; 40mm and 44m. Below are the differences between the two sizes.
Samsung Galaxy Watch Active 2 (40mm) vs (44mm): What’s The Difference?
Both sizes have the same thickness size of 10.9mm which is very slim, however, while the 40mm version weighs slightly less than the bigger 44mm which makes it more comfortable to wear, it has a smaller display size which means you get to see a little less at a glance.
- The 44mm has a 1.4 inches display size compared to 1.2 inches of the 40mm unit.
- The 44mm also has a bigger battery capacity and subsequently longer battery life than the 40mm unit. I get about 2 days with the 44mm unit, while the 40mm unit can get you up to 24hrs+ battery life.
Which Size is Right For You??
Depending on your wrist size, the varying sizes are meant to give buyers options to choose what size is best for them. So, in that case, the smaller 40mm will make a perfect fit for women and those with a slimmer wrist, while the 44mm is a better fit for men and those with moderate to fat wrist.
