In this review we are going to systematically and scientifically test the ins and outs of the Galaxy Watch 6. The focus will be on the health and sports tracking capabilities of this new release from Samsung, based on more than two weeks of testing, which did result in a few surprises. We will test the heart rate tracking accuracy, sleep stage tracking performance, GPS tracking consistency and low oxygen saturation detection. As always, I do not want to waste your time, so there are timestamps in the description below, so you can easily navigate to those things that matter to you. Let’s get started.
Hello everyone! For those of you that are new to the channel, my name is Rob, and I am a postdoctoral scientist specializing in biological data analysis. This will be my first in-depth review of the Galaxy Watch 6, and compared to my initial review a few weeks ago, there were a few surprises now that I have about 4 times more data to work with. As always, I am not going to bother listing the detailed specs of this watch, since you can find those on Samsung's website. The most important things to know are: the screen is a bit bigger, the processor is a bit newer, it now uses Bluetooth 5.3 instead of Bluetooth 5.2 and the RAM has increased slightly, otherwise the Watch 6 is largely similar to the Watch 5. So instead of going through the specs, we are going to be purely focussing on independent testing of the performance of this watch, since Samsung did promise improved health tracking. As always, let’s start off by looking at the heart rate tracking performance of the Galaxy Watch 6 classic, which I tested during a total of 9 indoor cycling workouts, 18 outdoor cycling workouts and 8 weight lifting sessions.
Alright, but what's the final verdict? Well, it's not that different from my impression of the Galaxy Watch 6 classic I reviewed a week ago. In terms of health and sports monitoring, the Galaxy Watch 6 seems to be an average performer overall. It manages to track my heart rate well enough under easy conditions, but not when the circumstances become a bit tougher. The oxygen saturation measurements were pretty good actually, and with GPS tracking was good enough, as long as you don’t care about any of the details. On the other hand, the sleep stage monitoring wasn’t impressive, very often recording way too much awake time and limited deep sleep.
