Apple Watch 6 review: blood oxygen test is here, and hand washing test

Today's living standards are gradually improving, and people are paying more and more attention to their health. Coupled with the outbreak of the epidemic this year, people are becoming more and more concerned about their own health. So the question is, is there any way to monitor people's physical health in real time?

With the continuous development of technology, manufacturers have begun to add many health functions to their smart watches . The one with the best reputation in the market is Apple's Apple Watch .

On September 16, Apple officially launched a new generation of smart watches-Apple Watch Series 6 at the new product launch conference. Compared with the previous generation, Apple Watch Series 6 has a new blood oxygen detection function, the processor is upgraded to S6, the overall performance is increased by 20%, and the brightness of the all-weather display (without frequent wrist lifting) is increased by 2.5 times. The pre-installed watchOS 7 of Apple Watch Series 6 brings users new functions such as family sharing settings, sleep tracking, and hand washing detection.

Late blood oxygen detection function

In fact, many Android smart watches already support the blood oxygen detection function, and Apple Watch Series 6 can be regarded as being used, which is definitely a happy thing for fruit fans.

Apple Watch Series 6 has a built-in brand new blood oxygen sensor, composed of four groups of LED light clusters and four photodiodes. These components are all integrated in the new crystal glass case back. When the user opens the blood oxygen App and performs blood oxygen detection, red and green lights will be emitted on the case back.

These lights will illuminate the blood vessels of the wearer's wrist, and the photodiode will measure the amount of light reflected, and then the AI algorithm will calculate the color of your blood to determine its oxygen content.

From a medical point of view, blood oxygen level is an important indicator of a person's overall health. It helps to understand the body's ability to absorb oxygen and the amount of oxygen transported to the body through the blood. Under normal circumstances, blood oxygen levels of 95% and above are normal. If the value is lower than 95%, the user may need to pay attention.

It is worth mentioning that when performing oxygen detection, you will see a very cool transition animation. At this time, you may sigh that Apple is an animation or advertising company delayed by technology.

In addition, in order to ensure the accuracy of the measured data, when using Apple Watch Series 6 for blood oxygen detection, you must place your wrist flat on the table or leg. During the measurement, the wrist cannot be moved, or the system will automatically terminate the test and remind you The user restarts the measurement.

The specific data can be viewed in the iPhone Health App. At present, the blood oxygen data measured by Apple Watch Series 6 is temporarily unavailable for medical use, but in order to solve this problem, Apple is also actively cooperating with medical experts, just like the watch’s slogan "A healthy future, wear it now" .

What improvements did the chip upgrade get?

With the addition of blood oxygen detection, the health function of Apple Watch Series 6 has been further improved. To achieve such a multi-function, of course, powerful performance is indispensable. The Apple Watch is equipped with an S6 chip based on the A13 Bionic Magic Modification. According to the official statement, the overall performance is increased by 20% and the operating speed is increased by 20% compared to the previous generation.

In order to verify the running speed of Apple Watch Series 6, we found a colleague’s Apple Watch Seiries 5 for comparison. Both are the latest watchOS 7 systems. According to actual measurement, when the same App is opened, the Apple Watch Seiries 6 on the right does seem to be slightly faster, but the gap between them is not big.

In addition to the increase in the speed of opening the App, the upgrade of the chip has also brought a brighter screen. Thanks to the better power consumption control of the S6 chip, the screen brightness of Apple Watch Series 6 has been increased by 2.5 times, which means that users can see clearer content when viewing the watch in an environment with strong outdoor light.
