On the day of the release of Huawei Mate 30 series, Huawei Watch GT2 also came.

As Huawei’s flagship watch, it has experienced a good reputation and market performance of the first generation. Although the second generation release is not as good as Mate 30, it is a heavy product for the wearable device market. It is.

Huawei Watch GT2 The most eye-catching place is its long battery life of two weeks. It can be said that it is one of the longest life-sustainable wearable devices on the market.

However, for smart watches, battery life is only the basis, and the function determines its upper limit. Huawei Watch GT2 Such a product, how about the performance?

More integrated design

As a device that is “opening” in almost 24 hours, it is important not to look good.

Although its overall design is not much different from the first-generation Huawei Watch GT, at first glance, it will soon be attracted by the large screen made of the integrated 3D curved glass.

Huawei Watch GT2, which is loved by Ai Fan, is a sports model with red color. This screen looksIt is round and clear, and the bezel around the screen is also narrowed. It is made of ceramic material and engraved with numbers and scales.

Compared to the first generation, its screen extends from the dial to the scale of the outer casing, and then bends down to the edge, so the overall look, there is a feeling that a clear spring will pour out.

On the back of the watch, you can see that the center integrates a heart rate sensor, a metal contact charging interface, etc. There are also gyro sensors, air pressure sensors, capacitive sensors, ambient light sensors, etc., which make the Huawei Watch GT2 have A stronger monitoring capability.

The new model is available in two sizes, 42 mm and 46 mm. We got the latter. Not only does it have a thinner body, the thickness has been reduced to 10.6mm, and the screen has been upgraded to a 1.39-inch AMOLED display with a screen pixel density of 326ppi and a resolution of 454 x 454.

As a smart watch with full scene coverage, the Huawei Watch GT2 screen is not bad in outdoor scenes with high screen quality requirements.

The watch is mainly operated by touching the screen. There are two buttons next to the watch. The up button enters the menu bar, long press to turn the machine on and off, and the down button enters the exercise interface.

In addition, the screen can also choose long light, the brightness can reach 1000 nits, but the long light time can only choose 5 minutes, of course, the scenes that need to stimulate the highest brightness are rare.

There are 14 backgrounds in the dial, but if you want to change the custom dial, you can use Huawei’s “one touch” technology to touch the watch and the connected mobile phone, you can quickly put the phone The photo is set to the dial background.

In terms of wearing comfort, the piece we got is a rubber strap. It feels skin-friendly after wearing. It doesn’t feel sticky and oppressive, and it weighs less than 50g and looks heavy. This is not the case.

But because my wrist is thin, this watch is really big and round in my hand.

A good companion for the fitness group

Smart watches are generally able to monitor and track the body. The Huawei Watch GT 2 extends a wider range of sports modes and more practical health management features.

For the first time, you need to download the Huawei Sports Health app. After pairing, you can use your watch and sync your data. Whether you are lazy or fat, it has 15 ways to get you moving.

These sports modes include 8 outdoor sports such as running, walking, hiking, hiking, trail running, cycling, open water, triathlon, as well as walking, running, cycling, swimming pool, free training, ellipse 7 kinds of indoor sports such as machines and rowing machines.

It is worth mentioning that in the swimming mode, the Huawei Watch GT 2 can perform underwater heart rate monitoring, the water depth can reach 50 meters, and the waterproofing is about 10 minutes. Generally, only full-function sports watches have these functions.

Although not as deep as the test, daily showers, shoal swimming, and water splashes are fine. When the swimming intensity is not in the exercise heart rate zone, the watch will give a corresponding message reminder and perform corresponding exercise guidance.

However, for the average user, more usage scenarios are still walking, running, cycling and other sports.

We tried the run first. Choose the outdoor running mode and follow the voice prompts. The watch also features GPS optimization and dual satellite system positioning for real-time route planning during sports.

When exercising, Huawei Watch GT 2 also records my body data synchronously, including heart rate, pace, distance, time, steps, stride, heat, altitude, etc. I can watch the watch during exercise. The value on the screen adjusts its status at any time. When the heart rate is too high or too low, the watch will also remind you when you are not exercising.

After all, for the young people of the present age, the work envied by the previous generation to blow air-conditioning in the office is not new now, and the employees are at the station for one day.

After a sudden strong exercise, it is easy to cause the heart rate to be too high or too low. It is necessary to adjust the state in time.

After exercise, the watch will perform a corresponding analysis and give advice based on my physical changes.

App can see complete chart data for each exercise, including walking trajectory, real-time pace, real-time heart rate, interval percentage, etc. Based on these data, we can develop more targeted movements later, such as increasing fuel consumption. Lipid, time to increase aerobic endurance, etc.

Follow it step by step, and there is a feeling of being guided by a personal trainer.

When I was writing in the office for a long time, it would not be able to shake it, and the dial showed a “warning quote”:

The World Health Organization lists sedentary as a serious health hazard.

It is worth mentioning that Huawei’s new smart watch is equipped with a microphone and speakers for the first time.

This means that when you are exercising, you can answer and make a Bluetooth call directly through the watch. The watch can receive calls from your wrist within 100 meters of the phone. This range is enough for you to throw your phone in the locker room and then talk in the gym or pool.

At the same time, the watch has a large storage capacity and can store about 200-500 MP3 songs, and speakers can play music. Although the sound is generally felt, the sound is still louder, and most importantly, it allows people to listen to songs while exercising.

However, if you exercise in the outdoor or public environment, it is recommended not to open the outside. At this time, the Bluetooth headset is the correct solution.

In addition, Huawei Watch GT 2 also supports mobile scan code payment and NFC bus card swipe function. So go out shopping, or before using the subway and bus, pay directly with the watch to pass the gate or Alipay, you can go out without a mobile phone, which also increases its practicality.

24-hour health manager

In addition to sports and fitness, Huawei Watch GT 2 has spent more time on health.

Health monitoring is now becoming one of the core functions of smart watches. Especially for young people who work overtime and stay too much, the heart problem is a potential hidden danger that they can’t ignore. For the middle-aged and elderly people who have a clear diagnosis of heart disease, the top of the head is like a sword of Damocles.

Huawei Watch GT 2 is the first to introduce a new feature: blood oxygen saturation monitoring.

If you are unfamiliar with blood oxygen saturation (SpO2), simply speaking, it refers to the concentration of blood oxygen in the blood, which is an important physiological parameter of the respiratory cycle. Older people and people with long-term mental work will have Decreased blood oxygen saturation, fatigue, drowsiness, slow response, memory loss, etc., will cause serious damage to the brain myocardium. In the alpine plateau and other sports, there will also be an indication of hypoxia.

I tested this in the middle of the night when I wrote this manuscript, showing that the oxygen saturation is still quite high, reaching 97%, which may be why this article can still have the latter part.

In addition, Huawei WATCH GT 2 joined 301 Hospital (Chinese People’s Liberation Army General Hospital) heart health research program, can provide new features for cardiac premature screening.

Premature beat is also an important indicator for detecting heart disease. It is a kind of heterosexual heart rate in arrhythmia. When there is no obvious symptom, Huawei WATCH GT 2 tries to help people prevent this risk in advance.

The official said that based on the experience of 301 hospital experts and Huawei’s artificial intelligence algorithm, not only can make accurate judgments on the hop-by-hop premature beat waveform, but also capture the abnormal premature beat heartbeat throughout the day. This function needs to be monitored with the Heart Health Research app. After the test, the results show that I have “no abnormalities”. The page also gives some dietary advice.

The Huawei WATCH GT 2 can be a useful addition to professional medical surveillance.

It is more intimate that the 301 Hospital’s MAFA system can provide closed-loop management services for users with suspected premature beats. If necessary, doctors in more than 70 hospitals can be diagnosed, treated, followed up and followed up.

In addition, there are functions such as pressure monitoring and sleep monitoring. Stress monitoring allows you to see what state you are in every day, high, medium, normal or relaxed.

This is mainly used by Huawei’s self-developed HUAWEI TruRelaxTM technology, which helps users relieve stress by recording HRV (heart rate variability) values ​​and providing feedback on user stress index.

The sleep monitoring will happen automatically after you wear your watch. The Huawei HUAWEI TruSleepTM 2.0 sleep detection technology is also used here. When you wake up, you can see yourself sleeping well in the app all night. .

In the app, you can not only see your sleep score, but also give you sleep advice through big data analysis, such as “handling out work or learning tasks, listening to light music or doing stretching exercises, then Go to bed.”

Currently, 301 Hospital Heart Health Research has expanded its research direction, such as the upcoming sleep apnea study. Huawei has also joined the research project. The follow-up will be based on Huawei’s heart rate and blood oxygenation technology to record your entire night. Sleep heart rate and oxygen saturation, then help you analyze the risk of sleep apnea.

In the app, I can also record the steps to be performed every day. The calories burned and the number of standings are equal to the information of my body. I have to say that this is a healthy lifestyle and lifestyle. Cheng, still quite supervised.

No longer think about it, it shouldn’t be charged

It can be said that contemporary people are always shrouded in a panic of less than 10%.

Whether it’s a cell phone, a watch, or a Bluetooth headset, endurance is a vital part.

Huawei Watch GT 2 has more new features, and people are most worried that these features will put a greater burden on the battery.

Huawei official said that this watch can provide up to two weeks of battery life, including Bluetooth calls for 10 hours, music for 24 hours, GPS mode for 30 hours, and up to 30 hours of battery life time.

In essence, it is mainly because of Huawei’s first low-power chip Kirin A1.

This chip is the first Bluetooth dual-mode 5.1 certified processor that allows the watch’s Bluetooth connection to be more fast and stable. It can still be used when working under multi-sensors such as sports, music, smart heart rate and sleep monitoring. Low-power operation, and the table is also equipped with a new power-saving algorithm 2.0 mode, which can identify the mode used by the user and process it accordingly to achieve a balance between performance and power consumption.

These all allow Huawei to maintain sufficient power in daily life.

Two days before I fully charged it, I kept wearing my watch on my hands. The usage scene included daily commute to the company, running after work, sleeping at night, and playing about an hour of songs. Two days later, the power left 79%; after a single night of sleep monitoring, the watch only woke up, the watch only lost 2% of the electricity; the middle put a fake without excessive use of the watch, on the ninth day, 42% remaining .

So, although it has a lot of functions, it is expected to be able to maintain at least one week of wear when it is worn for a long time and uses multiple functions. Compared to other watches, the battery life is still excellent, and short-term travel can be competent.

Today is the 12th day of use, and it has 20% remaining.

In the end, we charged the watch once and it was full in less than an hour, so we don’t have to take it off at night to charge it. The battery panic is almost non-existent on this watch.

Summary

In the past two years, sales of smart watches have increased significantly.

According to Market Research Corporation IDC’s recently released report, shipments of smart watches reached 47 million in 2018 Block, there will be faster growth this year.

By 2022, global smartwatch shipments will more than double to 94.3 million, accounting for nearly half of the total shipments of 190.4 million wearables in the same year.

It’s worth noting that smart watches are still paired with the same brand of mobile phones to get the best experience.

I connected the watch with the iPhone and Huawei Mate 30 Pro respectively. Although the same Huawei sports health app is used, the iOS version cannot use the complete heart health research function, as well as the lesson plan, local music, and custom dial. Some details such as the sports annual report cannot be experienced.

Compared with the previous generation, Huawei Watch GT 2 has a large upgrade in appearance, configuration and function, including the use of Kirin A1 chip, with microphone and speaker, support for premature beat screening,Snoring risk screening, blood oxygen monitoring, etc., the price has also changed from 1488 yuan.

However, Huawei Watch GT 2 also has some shortcomings. For example, motion data cannot be synchronized to other sports apps. If you change this new table, you must give up the previous motion data. In the smart part, the applications it supports are also Not too much, it becomes a bit “hardcore” for users who want to make their watch more playable.

Therefore, for the current trend of smart watches, it has actually moved from the previous “trying to replace some mobile phone functions” to “healthy living partners”, Apple Watch is the same, Huawei Watch GT 2 is also true.

In this nearly half-month period, I wear it almost every day. I have only charged it once, and I don’t even think about whether it is running out of power. In addition to the satisfaction of the endurance, a variety of fitness and health monitoring, let me slowly start to care whether it is healthy, exercise is enough, it does not form a driving force for my exercise and fitness.

This is also the potential of a smart watch: to help users develop healthy living habits and get a peace of mind.

This kind of peace of mind is perhaps it gives meThe biggest change brought by life.
