On the health side, you now have faster, simpler workout tracking through both the Samsung Health app and the widget. It now tracks outdoor swimming, too. You'll find Apple Watch-style high heart rate alerts and more detailed sleep tracking that compares your average to your age group. And when you launch Samsung Health, you'll see the Daily Activities screen right from the start to keep tabs on your progress.

Your watch might even last longer. There are promises of better battery life, in part through more aggressive memory management that closes background apps and tweaks settings. You can fine-tune other settings, such as the brightness and screen timeout. While these features won't be so hot if you aren't enthused with One UI's memory management, they could be helpful if you're determined to get through a weekend without recharging your wristwear.
