1. Preface: Huami popularizes blood pressure screening, bringing comprehensive health management
Nowadays, with the popularization of wearable devices, the homogeneity of the smart watch market is becoming more and more serious, and both appearance design and functional experience are becoming consistent. All brands have to try their best to add special functions to their products, such as body temperature detection, car-machine interconnection and other functions.
In fact, in this smart era, our original intention of wearing smart watches is not only to check time and message notifications at any time, but the most important thing is to be able to grasp your own health status at any time, followed by data and indicators of various sports.
Speaking of "health", Huami Technology has always been "connecting health with technology". Every smart watch product launched by it is built around "health".
On September 19, Huami launched the new generation Amazfit GTS 4 square smart watch, introducing "blood pressure screening research" in this series for the first time and supporting automatic screening at night. In addition to being richer in health functions, GTS 4 is also more comprehensive in functionality.
. Introduction of blood pressure screening research. Health management is more comprehensive.
Huami watch first introduced the blood pressure monitoring function. It was last year's Amazfit GTR 3 Pro. It was highly praised by users once it was launched, and it also started the wave of blood pressure measurement for smart watches.
This time, Huami applied the blood pressure screening research function to the thin and thin GTS series. At the same time, the upgraded sensor adopts a 4-channel layout of dual three-color lights, and the data acquisition volume and exercise heart rate monitoring accuracy have been improved.
. Added independent speakers to support Bluetooth calls
The previous generation GTS 3 did not have speakers. This generation of GTS 4 completes the regret, adding independent speakers and microphones, which can be used to connect and make calls through Bluetooth connection of the mobile phone.
also has built-in NetEase Cloud Music. We can download our favorite music to the watch, play it out through the speaker, and even play it through the Bluetooth headset to enjoy the music anytime, anywhere.
, a larger battery for long-lasting battery life
Amazfit Yuewo GTS series has always been known for its thinness and lightness. Since its release in July 2019, it has been pursuing the concepts of high appearance, high performance, and high reliability. Since it is a square dial, the screen can be larger than the circular dial, so it is also a point that the GTS series needs to break through in terms of battery life.
The new generation Amazfit The built-in battery capacity of the Yuewo GTS 4 has increased from 250mAh of the previous generation to 300mAh, and the daily use time has reached 8 days. While increasing the usage time, it also takes into account lightness and thinness. With a weight of only 27g, there is no weight bearing for girls to wear.
The following are the specific parameters of Amazfit GTS 4:
. Appearance: a classic small square watch. The large screen takes into account both light and thin
Amazfit GTS 4 is equipped with a 1.75-inch AMOLED square screen on the front, with a resolution of 390×450, and PPI reaches 341.
At the same time, this screen supports natural mode and bright mode, and users can choose any display mode that suits them.
Amazfit The GTS 4 from the middle box to the lug adopts an integrated design, and the visual effect is cleaner and neat. The watch body of
is made of aerospace and aluminum alloy, which takes into account the texture and looks light and thin. The thinnest part of the fuselage is only 9.9mm, and the weight is as light as 27g. Even girls don’t feel heavy when wearing it.
is consistent with the previous generation. The Amazfit GTS 4 watch uses a rotating digital crown, but this generation of crowns incorporates an amber-like design element, showing a gem-like luster while rotating.
crown uses stainless steel , and the surface is equipped with a sandblasting process, which significantly improves the overall texture.
is equipped with a dual triple-color light 4-channel BioTracker 4.0 sensor and two magnetic charging interfaces on the back of the watch.
The version we received is a watch strap made of fluoroelastic material, with a width of 20mm. The buckle adopts a classic pin buckle design, which is easy to wear.
strap adopts a quick-release design and has fluoroelastic and nylon strap materials for users to choose from.
Amazfit Yuewo GTS 4 packaging is equipped with a magnetic charger and instruction manual.
3. New blood pressure screening research: Support night automatic screening, health data can be seen
Amazfit Yuewo GTS 4 small square watch introduces the most important health function of the former elder brother GTR 3 Pro - blood pressure screening research. It is equipped with the PumpBeats blood pressure monitoring engine. Through cooperation with Peking University First Hospital , we jointly study the screening effect of wrist smart blood pressure watch on hypertension in people with undiagnosed hypertension .
Before using the blood pressure monitoring function, blood pressure research and screening is required to be added to the ZEEP APP.
Next, we need to use the upper-arm medical blood pressure meter to perform data calibration 3 times and manually input it into the APP. Then Amazfit GTS 4 will deeply learn and perform 30 seconds of automatic calibration.
It should be noted here that in order to ensure the accuracy of the measurement data, Amazfit GTS 4 needs to be calibrated at least every 28 days. After the calibration is completed, we perform measurements.
After 30 seconds of measurement, the watch will not only display diastolic blood pressure and systolic blood pressure , but also display the measured heart rate.
From the measurement effect, the data given by the watch does not differ much from the data measured by the professional blood pressure instrument .
Through the ZEEP APP, we can view the blood pressure measurement results in real time, and have a data curve chart to visually display it. We can also obtain statistics on the highest and lowest values of daily contraction and diastolic blood pressure.
Amazfit GTS 4 supports automatic blood pressure screening at night. When the device monitors that we are sleeping, the blood pressure data will be automatically measured at a frequency of 5 minutes/time, and the monitored data will be plotted into a curve.
However, it should be noted that Since the watch measured data is based on the blood pressure algorithm of the wrist PPG signal, the blood pressure change during measurement is predicted based on the blood volume changes of the microvascular blood vessels in the wrist by measuring the difference between the signal characteristics and calibration. Blood pressure screening research function is recommended for the wearer to use it himself and should not share it with his family.
In addition, the research and application of blood pressure screening and Amazfit GTS 4 smart watch is not a medical device product. The blood pressure measurement and blood pressure calibration provided are all used for blood pressure screening projects. They are for reference only and are not used as the basis for medical diagnosis and treatment.
4. Health: Five indicators for one-click measurement. Master health data at your fingertips.
—heart rate, blood oxygen , pressure monitoring
As a smart watch, the three routine health monitoring must be indispensable. Amazfit GTS 4 supports all-weather heart rate, blood oxygen saturation and stress detection.
Thanks to the latest generation of Huami Technology's self-developed BioTracker 4.0 PPG biotracking optical sensor, it adopts a 4-channel layout of dual three-color lamps, which greatly improves the data acquisition capability and accuracy of Amazfit GTS 4 compared with previous generations.
first is heart rate monitoring. Amazfit GTS 4 is equipped with the new BioTracker 4.0 biotracking optical sensor, which supports 24-hour heart rate monitoring all-weather. Combined with the upgraded heart rate algorithm, it can capture more signals, and daily heart rate monitoring is more accurate.
combined with ZEEP APP, you can view daily resting heart rate, average heart rate, maximum heart rate and minimum heart rate.
When the watch detects a high or too low heart rate, the watch will automatically issue a reminder to warn the user that the heart rate fluctuation is in an abnormal condition at this time.
Amazfit Yuewo GTS 4 supports 24-hour intelligent blood oxygen automatic monitoring. Thanks to the addition of BioTracker?4.0 sensor and the improvement of algorithms, users can accurately understand their blood oxygen status at any time.
blood oxygen saturation is an important physiological parameter of the respiratory cycle and represents the ability of blood to carry oxygen . The normal blood oxygen saturation of the human body is above 95%. The higher the oxygen content in the blood, the better the human metabolism.
Since the human blood oxygen saturation changes in real time, the Amazfit GTS 4 watch will automatically judge the physical activity status every 5 minutes. When it is recognized that it is currently sitting or quiet, it will automatically trigger the blood oxygen measurement, which ensures all-weather intelligent monitoring of blood oxygen saturation.
Secondly, the watch will record the highest and lowest values of the blood oxygen saturation of the day and calculate the average value of the day.
When the average value is standard, the watch will still make vibrations and sound reminders to warn us to adjust our physical condition in time.
Now we live in a fast-paced era, and daily pressure is inevitable.
Amazfit Yuewo GTR 4 also supports all-weather pressure monitoring. It can generate the highest and lowest pressure values and pressure analysis charts of the day in the background, and display them in four different colors. At what time the pressure is high, it is clear at a glance, and it is also convenient for us to watch it in real time.
—One-click measurement
One-click measurement function is also a unique function of Huami watch. Amazfit GTS 4 supports one-click measurement of five major indicators: heart rate, blood oxygen saturation, pressure, respiratory rate and heart health. After 60 seconds of detection, multiple data are mastered in one hand.
is really much more convenient than the frequent testing of smart watches from other brands.
——Sleep monitoring
Amazfit Yue Me GTS 4 can monitor our sleep status 24/7. It can not only monitor the time periods of deep sleep , light sleep, rapid eye movement and awake state, but also provide sleep quality analysis.
At the same time, the watch will record the breathing frequency when we are sleeping and intelligently judge the risk level of snoring.
Amazfit Yue Me GTS 4 has a new feature - "Customized Personal Sleep Plan".
"Customized Personal Sleep Plan" function is mainly a new feature specially added for the shift people. The sleep plan is cycled by week, and different daily sleep durations can be set, so that the watch can automatically record the sleep monitoring status status regularly, and the device monitors your sleep based on the planned period.
. Sports: 150+ sports mode Dual-band positioning is fast and accurate
Amazfit Yuewo GTS 4 has built-in ExerSense AI engine developed by Huami Technology, which can intelligently identify users' 8 sports modes such as indoor walking, outdoor running, and outdoor cycling.

or above is an outdoor walking test we conducted. The watch will monitor our movement status in real time, automatically turn on the built-in " walking " mode, and record the number of walking steps, walking distance, pace, heart rate range and calories consumed during exercise in real time.
During the walking process, slide the screen to the right to call up the music module, and enjoy the rhythm brought by the music during the exercise.
watch has an independent positioning system built-in, supporting the world's six major satellite positioning systems . It uses L1 + L5 dual-band GPS
technology, which can achieve faster navigation and recording of outdoor trajectories, and automatically generate motion trajectories after the operation of the work.
In the ZEEP background, we can see the walking route displayed in the map, and can view the average pace, average speed, number of steps, pace frequency, stride width and altitude information during the walking process.
This is the data we conducted the riding test. You can see information such as the cycling trajectory, distance, duration and pace in the watch. After the movement is over, a motion trajectory animation map will be automatically generated.
In the ZEEP APP, you can see richer data. Cycling sports generate animations on the map to vividly show our cycling routes, and you can also see information such as pace, real-time heart rate and altitude during our cycling process.
When we are doing outdoor running and outdoor cycling, Amazfit GTS 4 will remind you in real time during exercise, and you can know the exercise duration, safe heart rate, distance, energy supply, drinking water and other sports data that users care about without operating the watch.
. Featured functions: offline voice frees your hands. Various dials are matched with

Of course, with independent speakers, music playback function is naturally indispensable.
We can upload our favorite music through the ZEEP APP and store it in the watch. During the exercise, enjoy the music while exercising, improve the quality of exercise and enjoy the mood.
. Charging and battery life: 1 hour full battery. Use 8 days.
—Battery test
Amazfit Yue Me GTS 4 has a built-in 300mAh battery. According to official publicity, daily use can reach 8 days. If unnecessary functions are turned off, use smart watches as traditional watches, and the battery life can reach 30 days.
As a smart watch, health monitoring must be the first priority.
Therefore, when we turn on all-weather heart rate, blood oxygen saturation, stress monitoring and sleep monitoring, we also turn on the night sleep blood pressure screening function to test the battery life of the watch.
We started using it at 100% of the battery and simulated the usage status of daily users. During this period, we conducted two 20-minute riding and walking data records, totaling 40 minutes.
started to calculate at 19:30 on the same day. After 12 hours of testing, the time came to 7:30 on the next day, with 8% of the battery consumption and 91% remaining.
continues to be used until 21:30 on the next day, with a cumulative use time of 26 hours. At this time, the power consumption was 21%, and the remaining 79%.
After another night of sleep, it came to 7:37 am on the third day. At this time, the cumulative use time reached nearly 36 hours, with 29% of the battery consumption and 71% remaining.
is converted according to this power consumption speed. Excluding the motion record, the comprehensive usage time can basically reach about 8 days.
——Charging test
