We pulled together a list of currently available smart watches that met these criteria from Apple, Android Wear, and Samsung. Our list included watches from tech brands like Apple, Asus, and Samsung, as well as fashion labels like Fossil, Nixon, and Tag Heuer. Then, we cross-checked with respected review sites, such as Tech Radar and PCMag, as well as tech retailer Best Buy, to make sure we weren’t leaving out any hidden gems.
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.
The Charge 3's screen has 40-percent more active space than the Charge 2 has, and it makes for a better touchscreen overall. From the watch face, swipe from top to bottom to reveal the notification drawer; from bottom to top to see the daily dashboard; and side to side to see available apps. Transitions between screen pages are smooth, and stick-figure animations in apps like the Exercise app move with ease.
If you want a smart watch that uses cellular data without using up the battery, consider upgrading to the Samsung Gear S3. A close cousin to the Gear Sport, the S3 has all the perks of an LTE smart device (downloading apps, texting, checking email) and, unlike the Apple Series 3, it won’t quit after three hours. In fact, you could feasibly get 72 hours out of this LTE version of the Samsung Gear Sport.
It's also very bulky. Sitting at 46mm wide might not sound like much, but then you have the depth, and there's a lot of it here. In fact, if we had to pick one criticism of the Watch Sport it's that it crams so much in, it does so to its detriment. The size will be too overbearing for many, but the pay-off in size means that most of the great features of the Watch Sport have been discarded.
The Samsung Gear Live is the first of the company’s smartwatches to be compatible with any Android phone running Android 4.3 or higher; other Gear models can be paired only with specific Samsung phones. Like the LG G Watch and Moto 360, it runs the Android Wear OS, allowing voice commands and pushing relevant information to the wearer. Compared with the LG G Watch, we prefer the style and fit of the Gear Live. The watch body is slightly curved, which made it more comfortable. The Gear Live also has a heart-rate monitor, which the G Watch lacks.
The watch faces themselves are classic Kate Spade designs. You get a sultry winking moon face with perfectly curled lashes, calling you a leading lady; cute bubbly balloons for a digital watch face with numbers; a speeding cab that reassures you that you'll be there in a New York minute; and a daisy that loses petals as the time ticks away in a classic game of "He loves me; he loves me not."
We test every new smartwatch to gauge its design and comfort. If it’s not stylish and comfortable enough to get you from an early morning workout to the office to a night out, you probably won’t wear it every day. Most smartwatches are also fitness trackers, so we put all of its sensors to the test, from step counts to heart rate to GPS (when applicable).
