Battery life for the Q watches is unremarkably reliable, and that’s the best thing you can say about a touchscreen smartwatch. The Q Explorist never ran out of juice entirely while wearing it, even after having it be the primary turn-by-turn direction notifier on two 1-hour drives, followed by 30 minutes of actively tracked cycling and the usual all-day text/app notifications. While we didn’t wear the Venture for full days of testing, most reviews find no fault with the battery. The USB charger is a basic magnetic disc that slides onto the rounded back of the watch (though it could stand to stick onto the watch more strongly, like the Apple Watch’s similar disc).
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.
Our top pick for most people is the Apple Watch Series 4 with GPS (starting at $399), which has a huge display, ultra-fast processor, Raise to Speak Siri, fall detection and a built-in electrical heart rate sensor for taking on-the-go electrocardiograms. It also runs watchOS 5, which makes the watch even more useful with automatic workout-tracking, offline podcast playback and a Walkie-Talkie voice chat feature.
