You won’t get much use out of an Apple Watch if you don’t have an iPhone nor any other kind of iOS-enabled mobile device. The same thing goes for the Samsung Gear Sport. While the Q Venture does feature some compatibility with Android and iOS devices, it won’t mix well if you’re a Samsung customer. The smartphone you use will ultimately determine which smart watch you get the most value from.
The problem is that to monitor your sleeping patterns, a valuable feature most of these new smartwatches support, the watch needs to be on your wrist. So leaving your watch charging overnight while you slumber isn’t going to work. But smartwatches have small batteries compared to smartphones, so should only take 2 - 4 hours to fully charge, depending on the model.
Samsung's Galaxy Watch, a Tizen OS watch (starting at $329), is our favorite smartwatch for Android users. In addition to up to four days of battery life and a great design, the Galaxy Watch offers built-in GPS, heart rate sensor, water-resistance, Samsung Pay support, plus a nifty rotating bezel for navigating the interface. You can also download music from Spotify to the watch for offline listening. However, you get far fewer apps than you would with a Wear OS watch.
