Battery life and charging options: Charging your smartwatch is a hassle and the biggest downside to trading in your manually-wound or button battery-powered watch. A Fitbit Versa might last 3 - 4 days between charges, but a smartwatch like the Samsung Gear Sport or Apple Watch will need recharging every couple of days and sometimes every night if you are tapping on the screen regularly and using its apps.
Most stores that sell these smart watches feature display models that you can pick up and touch. We recommend getting a feel for how these watches operate before you invest in one of your own. Specifically, you’ll want to know the form of navigation each of these use to go through the various screens, apps, and functionalities. We were partial to twistable bezels and dials, but you might be used to swiping your way through screens.
Wirecutter writers have been researching, testing, and writing about smartwatches since early 2013, just after the first Pebble watches were shipped to Kickstarter backers. I’ve personally worn nearly every notable smartwatch since that first Pebble and have written about them for a number of publications, including IT World and Fast Company. I also have extensive experience with Android phones, having written the (since outdated) Complete Android Guide and numerous articles about Android. I also contribute to and help edit the Wirecutter guide to the best smartwatch for iPhones.
We actually got our hands on over a dozen of these smart watches just to get a feel for what it was like to use them. While all of them came with at least one main button (or a home button if you’re an iPhone-user), the ones that stood out had scrolling down to a science. On such a small screen, swiping isn’t always the most ideal form of navigation. Some of the best smart watches for navigation, we found, had twistable dials or bezels you could turn.
Software may include digital maps, schedulers and personal organizers, calculators, and various kinds of watch faces. The watch may communicate with external devices such as sensors, wireless headsets, or a heads-up display. Like other computers, a smartwatch may collect information from internal or external sensors and it may control, or retrieve data from, other instruments or computers. It may support wireless technologies like Bluetooth, Wi-Fi, and GPS. For many purposes, a "watch computer" serves as a front end for a remote system such as a smartphone, communicating with the smartphone using various wireless technologies. Smartwatches are advancing, especially their design, battery capacity, and health-related applications.
Samsung Gear S3 Frontier: Until we see what Google can pack into a smartwatch with its long-awaited Pixel Watch, the best smartwatch for Android users is the Samsung Gear S3 Frontier. It pretty much has everything a user with an Android phone needs in a smartwatch - GPS, heart rate monitor, water resistance, near field communications, an always-on digital display, messaging alerts and app support. I don’t see a real need to opt for the 3G version yet, which would untether you from your phone completely but adds around $100 to the price. ($549)
The Charge 2 was one of Fitbit's most popular trackers, so the company stuck with the winning formula with the Charge 3. If you're at all familiar with the Charge 2, you'll notice that not much has changed in the updated device—it's still a rectangular tracker hugged on its short edges by two parts of a band. Fitbit updated the connecting mechanism that lets you switch out the bands on the Charge 3, making it easier to press the black sliver of a button on either end to release the device's current band. The new band snaps right into place without any extra effort.
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.
