Introduction: What is your PAI today?
It is an indisputable fact that sports health has become the mainstream positioning of smart watches.
According to relevant statistical data, the proportion of sub-health of white-collar workers in mainstream cities in China is as high as 76%, nearly 60% of white-collar workers are overworked, and the proportion of healthy people in real sense is less than 3%; In addition to the impact of the epidemic at the beginning of the year, people began to pay close attention to personal health.
On April 30, Huami released the latest youth version 1S of Amazfit Meter Motion Watch, which is equipped with the health assessment system PAI developed in cooperation with the Medical School of Norwegian University of Science and Technology. This health assessment system is not used for the first time (Huami AMAZFIT smart watch 2 released in 2019 is equipped with this system), but it has sunk into the youth series of Midong watches for the first time by virtue of technical dividends. Lei Feng.com obtained the youth version 1S of this Midong watch in advance and conducted a detailed evaluation. The following is the actual measurement details of this watch:
parameter
Carbon black, rock white, red orange, warm pink, 4 colors, weight 31g
1.28 inch semi reflective color display, supporting all-weather display
2.5D Corning gorilla glass generation 3+AF coating
BioTracker ™ PPG biological tracking optical sensor, geomagnetic sensor
Sony GPS+GLONASS dual star positioning chip
30 day endurance, 50 meter swimming waterproof
NFC bus access control and Alipay offline payment
399 yuan
Appearance and wear: less 1g weight, more desire
The youth version 1S of Mido Watch adopts the classic design of rounded rectangle. The overall appearance is simple and durable, especially the pure black or pure white as a versatile color, which will not overturn with any clothes.
This basic product, which only sells 399, still uses 2.5D gorilla third generation glass and AF coating, and the glass radian is round and anti fingerprint effect is also standard.
The frosted body is integrally formed, and the back is BioTracker independently developed by Huami ™ The PPG heart rate sensor is one circle larger than the common sensor. The 20mm universal watchband is equipped with quick release buckle, which supports changing the watchband of other colors or materials.
After upgrading the screen and adding NFC, the overall 1S (including the strap) of the youth version of Mido Watch is 1g lighter than the previous generation of watches. The overall weight of 31g is even comparable to the smart bracelet. Therefore, when running and turning the wrist, even players who pursue the ultimate will not have an obvious sense of drag.
The silica gel strap is frosted, which makes the strap slightly hard. It needs to be worn for a period of time to allow it to naturally deform and adapt to the hand shape. But as far as the overall wearing experience is concerned, the texture and skin affinity are already very good.
Senseless wearing is the highest pursuit of all wearing devices. If one day you forget to take off your watch/bracelet when sleeping, it means that it is successful. As a daily wear watch, the youth version 1S of Mido Watch can also be worn without feeling to a certain extent, and even can sleep with it like a bracelet. Light, you can really do whatever you want.
Screen: equipped with "information screen display"
This 1.28-inch semi reflective color display screen is an upgrade highlight of the main hardware of the youth version 1S of Midaction Watch, with the number of colors increased by 8 times compared with the previous generation. Due to the reflective screen, the color can't compare with the screen of mobile phone and computer, but the color performance and animation effect are far richer than those of the early generation.
Some system dials
The special screen and the common LCD/OLED screen used in the youth version 1S of Midaction Watch follow two opposite paths, representing the two extremes of power saving and color respectively. The weakness of this watch is that the color performance and visual angle are slightly insufficient, but it can also reduce power consumption and improve the endurance of the whole machine.
This watch is designed to separate the backlight from the display, so that the screen can always keep the content displayed, while the backlight will only wake up when needed. In fact, this also realizes the rest screen display function similar to the current smart phone - there is no so-called rest screen status, the watch can display the time in real time without lifting the wrist to light the screen, or even without wearing or placing the desktop.
Watch display status when the screen backlight is off
In actual use, due to the use of semi reflective screen technology, this watch can not worry about the light intensity. The stronger the light, the clearer the screen will display, and the clearer you will see, thus avoiding some awkward scenes when using outdoor strong light.
Heart rate and health monitoring: high adaptation brought by self-developed software and hardware
The highlight of Midea Watch Youth 1S lies in its health function, which is also Huami's long-term efforts in the field of sports health, with particular emphasis on the technical advantages formed through independent research and development.
BioTracker on this watch ™ The PPG biological tracking optical sensor is just a sensor developed by Huami. The advantage of the self-developed device is that it will have a high matching degree with the ecology of its own software and hardware. Therefore, even if the 24-hour all-weather heart rate monitoring is launched to the frequency of one measurement per minute, it will not collapse the system and endurance. In terms of specific functions, it supports heart rate interval monitoring during exercise, which can help sleep monitoring with heart rate data. Later, it will also support the automatic screening function of arrhythmia (including atrial fibrillation).
The all-weather heart rate data will be recorded in the APP in the form of 5 minute values. In addition, when the all-weather heart rate is turned on, the watch will automatically turn on the detection when you draw to the heart rate monitoring interface, and these data will also be synchronized to the mobile phone APP.
In terms of heart rate accuracy, it performed normally during one week's use. The heart rate detection accuracy of the watch bracelet is affected by the user's wearing habits. It is recommended to wear it as tight as possible to ensure the accuracy of the heart rate sensor data while ensuring comfort.
The sleep detection function can bring players sad or happy mood when compared with previous data, and it can also be regarded as a little fun in boring life. In addition, it is rumored that REM (rapid eye movement) will be upgraded later, which can show a more detailed and comprehensive sleep state.
huami-PAI ™ Assessment system: health is hard won
Huami regards PAI as a new health evaluation standard. Huami PAI is installed on the youth version 1S of Mido Watch ™ Health assessment system, whose data is based on Huami Self developed BioTracker ™ The high-precision heart rate data collected by PPG biological tracking optical sensor can also be better polished on the combination of software and hardware.
Huami's evaluation criteria come from users' daily activity intensity and personal multi-dimensional dynamic physiological data, and then convert daily activities or exercises that bring changes in heart rate range into intuitive and readable PAI values, so that users can judge their health and exercise level according to PAI values.
huami-PAI ™ The health assessment system does not rely on the generation of single data, and is more systematic, scientific and effective than traditional simple data such as step counting and heart rate. Its scientific basis comes from the Fitness Study of HUNT, which is led by Professor Ulrik Wisloff of the Norwegian University of Science and Technology School of Medicine. The research has lasted more than 35 years, involving more than 230000 participants, and its scientific foundation can be said to be relatively stable.
Very detailed PAI description in APP
This PAI system is a bit like fighting monsters and level training. Every activity or sport that meets the intensity requirements can obtain PAI value. The more daily exercise, the longer the duration, the greater the value. The stable PAI value can be used to assess health and predict the probability of various cardiovascular diseases, and the official suggested that the target value should be set at more than 100.
The data of HUNT study shows that when the total PAI value is between 51-99, the risk of death caused by cardiovascular disease (CVD) in men is reduced by 11%, and that in women by 14%; When the total PAI value is ≥ 100, the risk of death due to cardiovascular disease (CVD) is reduced by 17% for men and 23% for women.
According to the actual measurement, the PAI value of the office still stays at 3 after giving up treatment and living in a dead house for 4 days. However, the moderate speed running of 500 meters twice a day, slowly climbing 11 floors, and persisting in 3 days can only increase the PAI value from 3 to 11. This kind of health statistics system, which is incorporated into the time dimension, avoids the impact of previous surprise exercise on the detection data. It can display directly, but also brings some challenges to players. It also confirms the aspiration of young people at present that health is hard won.
Violent endurance: start in one month
The endurance is a selling point that Huami Smart Watch has always emphasized. The endurance of this smart watch has been greatly improved again, even more than some bracelets. Even if the screen is upgraded and NFC is added, the official brand's endurance has reached one month. The basic endurance mode with heart rate turned off can reach 80 days, and the GPS and heart rate can reach 22 hours when they are normally turned on.
The measured initial power was 76%. After one minute of intensive heart rate detection and heart rate assisted sleep monitoring, the cell phone was continuously connected to receive and push, and 17% of the power was lost in five days. The performance was very close to that of the official standard in one month.
With such endurance, it's easy to forget where the charger is next time you charge it. It's really "you must keep your charger". After a week, our chargers haven't been unpacked yet
Life service: support bus brushing and access control
NFC bus and subway cards and NFC access cards are the focus of this upgrade. In terms of bus cards, 14 bus cards in different regions are supported, covering 313 cities including Beijing and Guangzhou.
The access card supports an unencrypted 13.56MHz access card. Like most mobile phones, many communities need to write white cards. If your access card is just right, or you can solve it with a little trouble, this function is very practical;
Alipay offline payment, in addition to binding with the Alipay account to deduct fees, now has a "wallet method", where the amount is pre deposited before consumption, separated from the Alipay account, which is more suitable for the elderly or children at home;
In addition, there is a waterproof upgrade that the official did not mention. It has been upgraded from the original IP68 to 50m waterproof. Now it is enough to wear simple diving.
Finally, the price of 399 is very friendly, even cheaper than the TWS earphones on the market today. The basic functions are also very restrained and grounded. On the contrary, you should worry that such a practical product will be like a Kindle. After using it emotionally, you will always feel "no reason to replace it" when you go to see the new product.
Actual measurement summary: technical dividend brings popularity of "flagship function"
The youth version of Midong watches is actually called Amazfit Bip in foreign countries. It is one of the best-selling watch products of Huami. As of the middle of last year, the shipment of the youth version of Midong watches has exceeded 3 million sets. The 2018 Comprehensive Best Smart Watch Award of BGR, a foreign media company, was awarded not to Apple Watch, but to Midaction Watch Youth Edition, which was also the third best-selling smart watch on the earth in the second quarter of 2018.
After upgrading the screen, waterproof performance, NFC, and the still strong endurance, the youth version 1S of Midong watch further strengthens its practicability. The addition of the PAI health assessment system makes the "health" attribute of the youth version 1S of Mido Watch more prominent.
As a "watch factory" that has been deeply engaged in the field of smart watches for six years, Huami has previously cooperated with many medical institutions and manufacturers in the field of sports health to carry out technical research and development in the field of sports health. The 399 yuan smart watch launched this time can be equipped with BioTracker, PAI, and arrhythmia local recognition health technology previously applied to high-end products, which is also benefited from the "flagship function" brought by its own technology dividend to further sink into basic products. From this point of view, the youth version 1S of 399 Midong watch may be a product with high technical cost performance ratio.
