But what’s new is that it will be able to detect lower VO2 Max scores. Well, technically, that’s been the case since Series 2-you can access your measurements via the iPhone Health app. For example, you might have learned that the watch can track VO2 Max now. The launch event presenters quickly highlighted some features that might make it seem like the Series 6 got exciting new updates. Apple has bumped the display on the Series 6 to be 2.5 times brighter in the inactive mode.

It worked pretty well, but could be a bit hard to read in bright sunlight. Like I mentioned earlier, the last generation added an always-on display, so you could see the time or your running pace without having to raise your wrist. Series 6 is faster still, even if just barely perceptibly so. Compared to early Apple Watch models-which were painfully slow, especially on startup-Series 5 marked a huge improvement in speed. One update that we can appreciate, however, is the better performance thanks to the new S6 chip, which allows apps to launch 20 percent faster without negatively affecting battery life. Their measurements are sometimes different. The Garmin Fenix 6X (top) and Apple Watch Series 6 both have blood oxygen sensors.
