The claim to fame on the Ticwatch Pro is battery life. The Pro offers up to 30 days of battery on a single charge. Of course, that all depends on how you use it. Mobvoi’s trick to improve battery life comes with the addition of a layered screen that acts as two displays. One is designed for use when the watch is idle, only showing crucial information such as the time to sip power. Under that is a standard OLED display that delivers the full Wear OS experience.
Its only drawback is its use of Samsung’s own Tizen OS. Tizen is a custom OS that’s based on Linux. On paper it’s pretty good, letting you pair the Gear S2 with any Android smartphone, not just Samsung Galaxy phones. But it’s nowhere near as developed as Wear OS, which itself isn’t perfect. There aren’t nearly as many apps available as the Wear OS app store, but the core functionality is at least present from what is available.
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.
When you do switch to the OLED display, you are in TicWatch Pro’s Smart Mode, and you can perform all of the features and functions that are available in the smartwatch. However, switching to the low-power FTSN LCD display puts the watch in its Essential Mode. The nice thing is that when you switch back to Smart Mode. all of the heart rate and steps info gathered by the watch’s Essential Mode are synced up and transferred to the onboard Wear OS. As you might expect, the battery life in Essential Mode can last up to 30 days, while using the smartwatch in Smart Mode cuts that battery life down to just two days.
To round off the Gear Sport’s positives, it has very solid battery life (almost never less than 50 percent of the battery remaining after a full day), it can play offline Spotify playlists (even for free accounts), and if you have a Samsung phone, it integrates easily with most of the apps you have installed there. The Gear Sport is easier to set up with a non-Samsung Android phone than previous versions of the Gear watch, too. It still requires the installation of at least four apps and some regular updating, but it’s not the hour-long trial-and-error of other Gear watches we’ve tested, working reliably in our testing.
I go for a middle-of-the-road approach—I enable alerts for most of my installed apps, save for ones that are niche (mostly shopping apps that alert me to coupons) or ones I don't use regularly. All alerts make the Charge 3 vibrate and show the message on its screen, and all past alerts live in the notification drawer that you can access by swiping down from the top of the Charge 3's display.
Smart watches are here to change the way you live. Now you can power through your workouts while the latest technology keeps track of your every move, check your calendar and keep an eye on the weather forecast wherever you are. You can also sync your smartphone with your watch, so you can check your texts, see who’s calling and receive notifications while keeping your iPhone 6 Plus safely tucked away.
