Like most other modern smartwatches, the Watch GT comes with a bunch of sensors that better equip it to monitor your activity. It has a tri-GPS system (GPS+Glonass+Galileo/Beidou) and an altimeter in addition to the six-LED optic heart-rate sensor to better measure your position, elevation and pulse. In fact, Huawei claimed it can more accurately monitor your position even in dense cities with buildings that could interfere with GPS signals because it taps the Chinese Beidou satellite. The Apple Watch Series 4 also has a tri-GPS (GPS/Glonass/Galileo) system, while the Galaxy Watch only has GPS and Glonass. If you're a city runner who wants very accurate info about your route, this could be a real selling point.
Another potential edge Huawei might have over its competition is its heart-rate monitor. The Watch GT uses AI to understand where and how it's sitting on your wrist and uses that data to clean up information from the sensor. This is supposed to help it deliver a more accurate reading, but obviously we haven't had a chance to verify that yet. I can say that it was impressively fast at measuring my pulse, though.
Like any fitness-focused smartwatch worth its salt this year, the Watch GT can also track your sleep and not just tell you how long you were passed out, but also the quality of your slumber. Despite my overall exhaustion and lack of coffee, I actually managed to not fall asleep during our hands-on at all, so I couldn't test this feature either.
Battery life is the big focus here, with Huawei promising that the Watch GT will last up to two weeks with heart-rate monitoring on and if you exercise for about 90 minutes per week. For more intense users, the watch will last about 22 hours with GPS and heart-rate monitoring enabled and the screen turned on. So, keep that in mind before heading out on your next ultramarathon. And we've got great news if you lead a completely sedentary life: With the heart rate monitoring and GPS turned off, the watch is supposed to last 30 days.
That's seriously impressive if true, and Huawei says it was able to achieve this through a combination of AI and a suspiciously unnamed custom CPU. Much like other chipsets that use Big.Little architecture, Huawei's mystery chip has a lower speed, energy-efficient component and a higher speed, power-intensive one. The AI decides which of the two to use, sending dynamic tasks like exercise-tracking to the bigger chip and static processes like showing the always-on display to the smaller one.
That architecture is just like what Qualcomm offers on its latest Snapdragon Wear 3100 chipset, which promises similar battery improvements. The watches using that CPU haven't launched yet, so we don't know exactly how effective the revamped architecture is right now, but it's certainly promising. With the Watch GT, Huawei is telling the world it still has a horse in the smartwatch race. But the company's decision to use its own OS is an unsettling one. From my brief preview, I don't see the appeal of LiteOS. Though, that might change after more time with it. For now, though, I'm just curious about whether the Watch GT will even go on sale in the US. Chances are you'll be able to find in online, perhaps through Amazon, at some point, but whether it'll find an audience here is something else.
Update: We don't know exactly where and when the new Huawei smartwatches will be launched, but we do know the Sport and Classic models will retail for €199 and €249, respectively.
