What’s the Difference?
The difference between these two is that the 45mm Galaxy Watch 3 is more compact than 46mm Galaxy Watch. Its bezel is smoother and it’s slimmer than the 12.7mm thick Galaxy Watch. The 1.4 inches display of the Galaxy Watch 3 is slightly bigger than the 1.3 inches of its predecessor. It also has a higher 8GB storage capacity compared to 4GB of Galaxy Watch.
The biggest difference between the Galaxy Watch and Galaxy Watch 3 comes in fitness tracking features. Galaxy Watch 3 has more health tracking features, it features blood pressure monitoring and ECG tracking both of which are offered through the Samsung Health Monitor app. Galaxy Watch 3 also features incidental fall detection, SpO2 blood oxygen monitor, VO2 Max., and running coach all of which Galaxy Watch lacks.
As per battery life, while I got an average of 3-4 days with Galaxy Watch, I got bearly 2 days with Galaxy Watch 3. Obviously, because the Galaxy Watch has a higher 472mAh battery capacity compared 340mAh of its successor.
Should You Upgrade?
Galaxy Watch 3 is clearly better than Galaxy Watch, so it’s worth upgrading. It’s less bulky, has a higher storage capacity, and more health tracking features.
Meanwhile, Galaxy Watch is still one of my favorite smartwatches, it has a very sturdy build with long battery life, and is also a comprehensive fitness smartwatch.
