A promising battery and another operating system



[ad_1]

Like most other modern smart watches, the Watch GT comes with a set of sensors that equip it better to monitor your activity. It has a tri-GPS system (GPS + Glonass + Galileo / Beidou) and an altimeter in addition to the optical six-LED heart rate sensor to better measure your position, your altitude and your pulse . In fact, Huawei claimed to be able to monitor your position more accurately, even in dense cities with buildings that can interfere with GPS signals, as it captures the Chinese Beidou satellite. The Apple Watch Series 4 also features a tri-GPS system (GPS / Glonass / Galileo), while the Galaxy Watch only has a GPS and Glonass. If you are an urban runner who wants to get very specific information about your route, this could be a real selling point.

Another potential benefit that Huawei could have on its competitors is its heart rate monitor. The Watch GT uses the AI ​​to understand where and how it rests on your wrist and uses this data to clean the sensor information. This is supposed to help to provide a more accurate reading, but we obviously have not yet had the opportunity to verify it. I can say, however, that my pulse measurement has been remarkably fast.

Like any smart fitness-oriented watch worthy of the name this year, the Watch GT can also track your sleep and tell you not only how much time you've lost consciousness, but also the quality of your sleep. Despite my general exhaustion and lack of coffee, I actually managed not to fall asleep at all, so we could not test this feature.

Battery life is the main focus here, with Huawei promising that the Watch GT will last up to two weeks with active heart rate monitoring and if you train about 90 minutes a week. For more intense users, the watch will last approximately 22 hours with GPS and heart rate monitoring enabled and the display turned on. So, keep that in mind before getting into your next ultramarathon. And we have good news if you lead a completely sedentary life: with heart rate monitoring and GPS off, the watch is supposed to last 30 days.

It's really impressive, if that's true, and Huawei says he was able to achieve that by combining artificial intelligence and a custom processor, whose name is suspicious. Just like other chipsets using Big.Little architecture, the Huawei Mystery Chip presents a low-speed, energy-efficient component, as well as a high-speed, high-power component of the game. ;energy. The artificial intelligence decides which of the two to use, sending dynamic tasks such as tracking exercises to a larger chip and static processes, such as permanent display at the smallest.

This architecture is in line with what Qualcomm is offering on its latest Snapdragon Wear 3100 chipset, which promises similar battery upgrades. The watches using this processor have not yet been launched, so we do not know how much redeveloped architecture is effective at the moment, but it's certainly promising. With the Watch GT, Huawei tells the world that he still has a horse in the smartwatch race. But the company's decision to use its own operating system is worrisome. From my brief overview, I do not see the appeal of LiteOS. Although that may change after more time with her. For the moment, though, I'm just curious if the Watch GT will even go on sale in the United States. Chances are you can find online, maybe by Amazon, at some point, but finding an audience here is something else.

Update: We do not know exactly where and when the new Huawei smart watches will be launched, but we know that the Sport and Classic models will cost € 199 and € 249, respectively.
