We've just completed lab tests on six of the newest smartwatches to hit the market. Three run on the very promising Android Wear operating system, which Google created specifically for wearable devices—the LG G Watch, Samsung Gear Live, and Motorola Moto 360. We also tested several basic models: the Martian Notifier, Cookoo 2, and MetaWatch M1. And we included reviews of nine smartwatches that we tested previously; all are still available, and we updated their prices. Find out what we liked and didn't like about the six newly tested models.
A smartwatch is a wearable computer in the form of a wristwatch; modern smartwatches provide a local touchscreen interface for daily use, while an associated smartphone app provides for management and telemetry (such as long-term biomonitoring). While early models could perform basic tasks, such as calculations, digital time telling, translations, and game-playing, 2010s smartwatches have more general functionality closer to smartphones, including mobile apps, a mobile operating system and Bluetooth connectivity. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth or USB headset. Some models, called 'watch phones' (or vice versa), have complete functionality of a typical smartphone using LTE technology.
The Amazfit Bip is thin and light, looks like an Apple Watch, has a lot of sensors inside—GPS, heart rate, accelerometers, barometer, and compass—and can run for about 30 days (which we confirmed) between charges, all for around $100. Those facts are compelling, but actually using the watch is frustrating, and it doesn’t do any one thing well. The GPS and heart-rate monitors can be slow to start, sometimes drop out, occasionally have wild inaccuracies, and produce results notably different from those of running watches and dedicated fitness bands. The screen is also dim and noticeably low-resolution, and the phone software for managing the watch is dense and unintuitive on Android. (We didn’t test iOS, but the reviews imply that it’s not much different.) The watch materials are plastic and rubber, and look and feel like it. Those are all trade-offs you could reasonably make if you just wanted a Pebble-like smartwatch that tracked steps and showed notifications, but even there, the Bip does not succeed: It often dropped connectivity with my phone (a Pixel 2), and it cannot show emoji—getting a dozen blank squares when someone sends you a thumbs-up sign is not helpful. If all you care about is battery life, the Bip has that, but it lacks useful functions while it’s charged up.
We loved Samsung’s characteristic bezel navigation. Instead of having to swipe your finger across the touchscreen repeatedly, all you have to do is gently twist the bezel. It’s a much smoother way of scrolling through your list and it just feels more natural. The are other side buttons which lie almost flush with the side of the watch, making it difficult for them to catch on sleeves.
Qualcomm is preparing to launch a new generation of wearable processors at an event in September. That’s likely going to mean new hardware and maybe even new capabilities within wearable operating systems. So at least for the next few weeks, it might be best to hold off on buying any new smartwatches, at least those still rocking a Snapdragon Wear 2100…
Inside the Charge 3 are an accelerometer, gyroscope, optical heart rate monitor, and an SpO2 sensor for tracking blood oxygen levels. The Charge 3 is the third Fitbit device to include an SpO2 sensor, following in the footsteps of both the Fitbit Ionic and the Versa smartwatches. However, currently the SpO2 monitor lies dormant inside all of these devices as Fitbit hasn't made use of it yet.
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.
