Samsung Galaxy Watch 3 vs Galaxy Watch Active 2 – What’s the Difference?
- Premium Designs
- More Storage on Galaxy Watch 3
- More Health Tracking Features on Galaxy Watch 3
Both smartwatches have got really attractive designs. Active 2 which has a rotating bezel looks a bit geeky, unlike the classic Galaxy Watch 3 that looks like a traditional watch. Active 2 is more compact and slimmer at 10.9mm than Galaxy Watch 3 which is 11.3 thick. It also weighs a little less, yet has the same display sizes as the Galaxy Watch 3. I can say Active 2 is a more comfortable smartwatch. One fine addition to Galaxy Watch 3 is that you can navigate the watch with only the rotating bezel without touching the display.
Galaxy Watch 3 has twice the storage capacity of Active 2 which of course allows you to take more tracks with you. As against 4GB that comes with Active 2, Galaxy Watch 3 comes with 8GB storage capacity. Galaxy Watch 3 also comes with a higher 1GB RAM compared to 0.75GB RAM of Active 2. This in addition to the new Tizen OS 5.5 brings improved performance and better UI features than Active 2.
Active 2 had come with ECG and blood pressure monitoring, but Galaxy Watch 3 also comes with these features and has more health tracking features such as VO2 Max., blood oxygen tracking, incidental fall detection, and menstrual cycle tracking. ECG tracking on Galaxy Watch 3 has already received clearance from the FDA and the first update to the watch has added VO2 Max., and blood oxygen tracking. These features may come to Active 2 in future updates. Besides, both smartwatches can track your sleep, heart rate, calories, stress, and feature preset workout modes to choose from.
Which is Better?
These two are some of the most sophisticated and outstanding smartwatches you can find on the market, both Galaxy Watch Active 2 and Galaxy Watch 3 have got really nice features and attractive designs. Although Galaxy Watch 3 has more storage and gives you the ability to navigate the watch without touching the display and for now has more health tracking features including the 120 preset workout modes.
Active 2 on the hand is cheaper and more compact. It’s a decent choice, while Galaxy Watch 3 is a better smartwatch, no doubt.
