The release of Kirin A 1 SOC and its new features.
On the afternoon of September 6th, Huawei released the first flagship 5G SoC chip Kirin 990 at IFA20 19, integrating the network functions of 2G/3G/4G and 5G into one chip. Smaller chip area can bring lower power consumption!
At the same time, Huawei also announced a brand-new chip: Kirin A 1, which supports Bluetooth 5. 1. The first product equipped with Kirin A 1 chip is the true wireless Bluetooth headset FreeBuds 3. According to reports, Kirin A 1 chip makes the performance index of FreeBuds 3 30% higher than that of Apple AirPods and reduces power consumption by 50%. Its package size is 95% of AirPods H 1 wireless chip.
Smart wearable products should be used close to the body, so "small, thin and light" is the most distinctive label, and it is also necessary to maintain interaction and linkage with smart phones, so connection stability and low power consumption are very important. Kirin A 1 Chip realizes a "compact size" of 4.3mm x 4.4mm by combining Bluetooth processing unit, audio processing unit, APP processing unit and independent power management unit, and can be implanted into any small wearable device. This is also the key reason why Huawei WATCH GT2 can use Kirin A 1.
It is precisely because the chip has the characteristics of small size, low power consumption and many functions that this Huawei watch GT2 should have many different functions.
Observe and guess 1: Longer battery life
According to the data, Kirin A 1 is a Bluetooth SoC (System on Chip) that supports TWS headphones and wearable devices, and it is also the first system on chip that supports Bluetooth/low-power Bluetooth dual-channel 5. 1 standard. Excellent anti-interference ability, high-performance dual-channel Bluetooth connection, and the delay is reduced by 30% year-on-year.
Kirin A 1 chip will greatly improve the stability of the connection with the smart phone during bumpy movement. The file transmission peak based on 4Mbps is about 2.5 times faster than the traditional Bluetooth data throughput, and the physical bandwidth is as high as 6.5Mbps, which is 2.8 times faster than the traditional Bluetooth. This will achieve faster and more efficient data synchronization between smart phones and smart watches. At the same time, it also means that the standby power consumption of Kirin A 1 chip is relatively low, or it will further extend the battery life of smart watches.
Speculation 2: Voice call function
Kirin A 1 Multifunctional Package represents that any device equipped with this chip can realize communication function by connecting a mobile phone. Therefore, it is speculated that this generation of Huawei watch GT2 will probably include a microphone and a speaker, and it is very likely to realize Bluetooth calling, listening to music and replying to WeChat voice messages, and even realize the function of using an intelligent voice assistant through the watch.
New features of rendering and patent exposure
Guess 3: new design
In the renderings and news of early exposure, Huawei WATCH GT2 is divided into fashion models-gravel brown and sports models-obsidian black. Judging from the exposure, Huawei WATCH GT2 will continue to use the classic round dial, the metal frame will be thinner, the touch and vision will be wider, the shape will be simple, and the vision will be clearer; The dial is thinner than the previous generation and the ears are longer. Straps are divided into fluororubber straps and leather straps, so the wearing comfort should be better.
According to the situation of the previous generation GT 1, GT2 definitely has more than two colors, and there should be very rich styles and colors to achieve more usage scenarios and user coverage.
On June 5438+07, the well-known website SlashLeaks released a set of official renderings of Huawei WATCH GT 2. It seems that in addition to inheriting the version of GT 1, there are new products for the integrated 3D glass surface design of dial.
Guess 4: Huawei Truseen technology upgrade
Not long ago, Huawei released a news in official website, "30 1 Hospital will release heart health research results based on Huawei wearable devices in the European Cardiology School Year", which introduced the results of Huawei's heart research series in detail: ① Screening high-risk groups of arrhythmia and atrial fibrillation based on PPG technology; ② MAFA II: Mobile medical technology supports the comprehensive management of atrial fibrillation.
On September 4th this year, Huawei submitted nine design patents to the European Intellectual Property Office, which were included in the patent library two days later. Each patent displays a different graphical user interface. However, these only indicate that Huawei WATCH GT2 will have some new dial appearances, with the focus on the 10 design patent submitted by Huawei.
In the patent 10 applied by Huawei, the graph of the heart rate monitor is displayed on the dial in the form of dynamic animation. Why did you suddenly change the previous heart rate detection animation? This point deserves further study. Combined with the previous research results of Huawei Heart Study series, it is not difficult to guess that the appearance of this new patent should be a new function of heart monitoring. Huawei Truseen technology upgrade will probably support atrial fibrillation monitoring on Huawei WATCH GT2.
Final summary
At present, there are not many products that can appear on the same stage as the flagship products. The two releases of Huawei WATCH GT are accompanied by mate series. Combined with Huawei's current layout in the field of intelligent interconnection and its strategic objectives, HUAWEI WATCH GT has a quite different position in the Huawei system.
