One day I suddenly received a phone call from the Royal Park's landline. After I connected, I thought that I was not selling the house. I was ecstatic about what the phone was worth to buy. I was concerned about what I was buying from 12 years ago. This is The first time I received a phone call from Xiao Bian, I forgot to have WeChat. . .
The general idea is that there is a person who is determined to abstain from voting. If I am willing to participate in this period of test as a candidate, as a millet loyalty powder, of course, wishing it could not, I readily agreed and wait for the arrival of the bracelet.
The millet bracelet is a product of the millet eco-chain company Huami Technology. After the millet bracelet generation was released in the summer of 2014, its low price, long life, full waterproof design, practical functions, and Xiaomi's brand appeal Swept the country, so that Wah Technology has become the world's second largest wearable device company. However, in order to control the price of the millet bracelet at 79 yuan, it does not have a screen or heart rate function. In the past two years, with the development of smart wearable devices, the generation of millet bracelets has been unable to meet the needs of users, so in June this year, millet bracelet 2 went on sale.
Because it was the weekend after confirmation, I hope that the stars will receive the express delivery from the moon. This time, it is not the label of Aunt Zhang’s “threshold valueâ€, which is a little lost.

Even if the company couldn't wait to open the packaging, it would be similar to the millet's outer box material, and it would use the original packaging style of Xiaomi instead of the new white packaging.
The packaging is similar to the generation of millet bracelets, but it is much flatter than the previous generation and also reduces the unnecessary space.
On the back is the product model, parameters and other information, typical Mie packaging features.
The opening of the box was almost stunning by such a design, and the black screen of the bracelet was extraordinarily deep under the background of yellow kraft paper.
Due to the presence of the screen, the surface of the millet bracelet 2 has a flat design and is slightly larger than a generation of particles. The texture looks good, too. The touch button below uses a radial brushed design that blends well with the overall black appearance. Finally, the entire surface is manufactured using a UV coating process, which can effectively prevent scratching and prevent fingerprint retention.
When you open the side of the millet granules, you can see wristbands, starter guides, and charging cords. The way to remove the granules is destructive. You must tear them to remove the granules.
In addition to the body of the millet bracelet 2, the wristband is a very important accessory because it is a thing that needs to keep in touch with your wrist. It is very important whether it is durable or not. Value-friends may have heard of how pits millet bracelet wristbands are. In addition to wearing a granule, the end loops of wristbands are easily broken. I also have a generation of original wristbands. Now. . And millet on the wristband warranty rule is 15 days after receipt, huh, huh. .
From the texture feel of the second generation and generation of wristband material is similar, the overall feel more comfortable, but also see improvement for a generation of problems, such as the particles can not be installed from the front, that is, particles can not fall out from the front, The circle at the end of the wristband seems to have thickened a bit too.
With the design of the particle body, the dark buckle of the wristband also becomes a ray-like drawing process.
Other accessories include instructions for use, charging lines, etc.
Finally, Zhang Quanfu ends the box.
The biggest difference of this millet bracelet is that it adds a 0.42-inch OLED display, and the screen can display the time, steps, heart rate, and cell phone alerts. Each time the touch key is pressed, it will switch.
In order to increase this screen, the 2nd generation is one lap larger than the 1st generation and the surface is evener. At the same time, the thickness has increased a lot, and the charged metal contacts have been changed to the inner package design.
In order to match the heart rate test, the back of the rice kernel has a heart rate monitoring module that looks a bit prominent, but it doesn't feel when worn, but only after it is removed it will have an imprint on the arm.
Due to the increase in the size of the rice kernels, the wearing comfort will be reduced. Especially for those of me who have particularly fine wrists, they have never dared to wear watches. In addition, the feel of the wristband is also very important. According to the millet's official statement, this wristband uses a double composite material. The main part is made of a tough elastic material. The body contact part is made of a softer skin-friendly material, and the wearing feeling is better than that of the generation. .
There is not much sense in the actual experience, but it is more profound for me to make adjustments to the bad wristband design. For example, the buckle of the wristband is more likely to be buckled. For example, the rice grain can only be inserted into the wristband from the internal measurement, and there is no need to worry about the falling out of rice grains when worn.
In general, because of the small weight of rice grains, long life time and waterproof design, they are basically not worn after being worn. The overall feeling is much better than a watch or a clunky smart bracelet, and sometimes even forget to wear it. Millet bracelet.
The companion app for Millet Bracelet 2 is Xiaomi Sports, which can be downloaded from the major app stores or the QR code on the instructions. It must be said that the function and interaction of this app have done a great job, adding a lot to the millet bracelet.
First of all, we need to make sure that the connection between the mobile phone and the wristband is Bluetooth, so if you want to connect, you must first turn on the Bluetooth function of your phone. Of course, if you do not open it, you will be prompted when you enter the app. At the same time after the first connection, you usually need to upgrade the firmware, which can be completed in about 1-2 minutes.
After entering the standard Mie style, focusing on the number of steps and other related data. The strange thing is that I did not buy a millet weighing scale, but I was not aware of how it was done, but it was only 55 kg.
The whole APP is divided into four modules: status, discovery, intelligent play, and my four modules. The "state" shows all the measured data, including the number of steps, sleep, weight, and heart rate. The bracelet can't test the weight, so it is recommended to remove or put the weight column to the bottom if you only connect the millet bracelet.
The demonstration of the amount of exercise has detailed data on the number of steps taken during each time period, and the overall recognition is fairly accurate. It also provides the function of counting the number of steps by days, weeks and months.
It is possible to quantify the movement of each period into the bar graph itself, but it is not possible to visually estimate the number of steps in each period of time. It would be perfect if the number of steps in the vertical axis could be increased.
Sleep monitoring has always been a trump card application for millet wristbands. Millet had a very high recognition accuracy at the time of its first generation. The time it took to sleep and wake up was very accurate, and the last time in the middle of the toilet or midnight can be accurately identified. Millet Bracelet 2 inherited this excellent quality and did a good job in sleep detection. Although it was impossible to measure deep sleep and light sleep, it was subjectively accurate.
In addition, it is regrettable that the millet bracelet 2 cannot recognize the siesta, so it is impossible to add the siesta time.
The heart rate function is a function added by the millet wristband generation of light sensitivity version. The principle is very simple, namely the photoelectric transmission measurement method. That is, the sensor in contact with the skin of the wristband emits a beam of green light on the skin and measures the reflected light. Because the blood absorbs light at a specific wavelength, each time the heart pumps blood, the wavelength is absorbed in a large amount, so that the heartbeat can be determined.
This type of technical difficulty is not hardware. In fact, there are many mobile phone APPs that can measure the heart rate using the flash of a mobile phone. The difficulty lies in the software algorithm for calculating the heart rate. Because there will be environmental interference light source first, it is necessary to reduce the ambient light source to a very low level. At the same time, the blood congestion information when the heart pumping blood is removed during measurement, and the blood shake information generated by the human body shaking, so how to plan the interference and get accurate The heart rate data is very difficult. This is the reason why the measurement value of the millet bracelet 2 is too high, and sometimes the true heart rate cannot be measured.
The millet bracelet will display the data of the previous heart rate, and the measurement can be initiated directly from the APP. The measurement bracelet screen initiated directly from the APP will not light, nor will it vibrate after the measurement is completed.
The second module of the APP "discovery" is mainly information on activities that increase sports, as well as smart hardware purchase links and insurance related to the millet movement.
The third module "Chi game" part is mainly some of the reminder functions using the bracelet and mobile phone connection, such as ring alarm clock, reminders, call alerts.
Some of these features are still very practical, I will be divided into two categories, one is the bracelet itself can be completed without mobile phone support, such as bracelet alarm clock, sedentary reminders and access third-party rankings. These three functions I have now opened, bracelet alarm clock has let me give up the mobile alarm clock, because the bracelet alarm clock can wake you up while not affecting other people. In addition, I am in front of the computer to work, it is easy for a few hours to sit and forget to get up activities activities, sedentary reminder function is a good reminder to promptly get up to activities, ways to produce a variety of sedentary hazards. In fact, access to third parties is only to see the rankings. Every day they can see others' rankings in real time. When they get the first time, they are still very satisfied.
The other type is that it needs to be connected to the mobile phone, that is to say, it must always be on Bluetooth, so it will have a certain impact on the life of the opponent's ring, such as incoming SMS alerts, APP notification reminders, and screen unlocking. I use the Meizu Pro6 system version restrictions, can not use the screen unlock feature, calls and SMS reminders are quite practical, basically do not miss the phone, APP notifications on the matter, and now mobile phone push so much, it is estimated that not many Individuals will pay special attention to push.
There's one more thing to note here. Whether it's an incoming call, text message, or an APP push, it only vibrates a few times and there is an icon flashing. There will be no reminder about the incoming phone number or which app is pushed. .
Finally, there are some bracelets and information to wear, such as power, whether to lift the wrist bright screen and so on. Compared with the Bracelet generation, the endurance capacity of the second generation has significantly decreased. It is no wonder that after all, there are more screens and heart rate tests, but it seems that it is not a problem for two to three weeks.
There is a wrist-lifting screen function. Before the generation of the wristband, the second generation seems to be a bit more sensitive. In most cases, the power screen can be recognized. However, due to algorithmic reasons, the screen will not light until it pauses for 1-2 seconds after lifting the wrist. This causes the wrist to be lifted, pauses, and then puts down the whole process. If it is a watch, it may be lifted and put down. This pause will appear silly, making the function of lifting the wrist bright screen become a tasteless.
In addition, you can also customize the type of information for the wristband limitation. In addition to the default step number, time, and heart rate, you can also display information such as history, calories, and battery power.
Overall, the overall performance of this millet's APP is excellent, without being affected by MIUI's random addition of advertisements. The overall style is simple and fresh.
About life and charging
The official life of the millet bracelet is 20 days. The actual use of the bracelet should be able to reach this time. It will not be concerned about whether the bracelet is still carried or not. The speed of charging is also OK. It can be filled in two hours. However, I still feel that the charging is not very convenient and mainly focuses on two points.
1. The charging cable and mobile phone charging cable are different and cannot be compatible.
It may be due to waterproofing that the charging device of the wristband is set to be now, but because it is not compatible with any other device's charging device and the charging cable is so short, I can easily find it somewhere. Finally, a special place was found to place the charging line.
2. Rice grains and wristbands need to be disassembled when charging.
The rice grains and the wrist band need to be tightly combined when worn, so the process of disassembly and installation is still a cumbersome process, and it will also increase the tightness of the wrist band and rice grains, which is also a place where the experience is not so good.
In summary, although the charging is not a high-frequency requirement for the bracelet, the charging experience is not good. It is hoped that Xiaomi can actively try wireless charging and other technologies so that the bracelet can be directly placed on the charging board without dismantling it. Charging. Of course, factors such as the weight of the coil that is added to the wireless charging need millet to trade off.
About waterproof
First of all, make sure that the millet bracelet 2 is waterproof, and that when someone saw the face wash their teeth, the bracelet was removed. . . Millet bracelet 2 waterproof level is IP67, that is, 6 dust, 7 waterproof, can be soaked briefly, under normal temperature and pressure can withstand a depth of 1 meter. The scene that is converted into our daily life is to wash your face, brush your teeth, and wear a millet bracelet when bathing. There is no problem, but swimming is long time soaking, so do not wear it when swimming.
I always showered with my handkerchief, but I found two problems in the bath. When the warm water touched the touch key on the bracelet, the wristband screen would light up, because the warm water is similar to the touch of a finger and I often go to the heart rate. Test mode and shake it. In addition, although the wristband is waterproof, the surface and the wristband are covered with water, and it is not easy to wipe dry when wiped, especially the part behind the wristband is not very comfortable.
In the past few years, smart wearable devices represented by wristbands (including watches) and glasses have sprung up and have largely replaced mobile phones as a personal information hub. In fact, our rational analysis, we will find that in fact the role of the bracelet is very limited.
First look at the interactive mode of the wristband. At present, most wristbands only have one or two keys. If it is a smart watch, the interaction mode is similar to that of a mobile phone, but the screen is much smaller than the mobile phone. This type of interaction restricts the bracelet from being able to take on more heavy tasks unless there is a breakthrough interactive approach, such as speech recognition (current speech recognition is weak), gestures or holographic projection.
Also look at the processing power of the wristband. Even if the previous interactive method is solved, the handling capacity of the wristband is also a big problem. With such a larger wristband, the battery also occupies a part of space, and it must be highly advanced. The processing capacity is very unrealistic.
Therefore, the positioning of the wristband should be an accessory of a mobile phone or other devices in the future. As an accessory of a mobile phone, the mobile phone can help the mobile phone to better satisfy the user's needs. At the same time, he can also have some independent functions, such as step, heart rate and other functions. From this perspective to consider the positioning of the millet bracelet is very clear, the success of the millet bracelet is positioning success.
In the independent function of the bracelet, sports and games are the two possible breakthroughs. At present, most of the bracelets focus on sports and fitness. Step counting is already the core function of the bracelet, but this function is currently done too. A single, can make the bracelet and fitness APP more popular now, in-depth excavation of the fitness market, increase the sticky hand, if you want to commercial later in the more convenient.
On the other hand, the current bracelet on the game interaction does not seem to enter this market, in fact, the bracelet can be used as a sensor to participate in the game. For example, if the wristband itself has a variety of sensors, it can capture arm movements, so that as part of the game operation equipment, such as various types of television sports ball, shake hands can play.
In the end, smart wearable devices will obviously not be limited to glasses and wristbands, but all products worn by the human body will be smart, and even future underwear will be smart. Imagine a future vest that can monitor your heart rate in real time. The alarm clock is a full-body outfit that oscillates (hehehehehe). When the phone calls, the belt directly projects the other party's holographic image. This is when the era of wearable devices comes.
Finally, summarize the advantages and disadvantages of Xiaomi Bracelet 2.
Millet bracelet 2 advantages and disadvantages summaryadvantage
1. The basic functions such as exercise records, heart rate, sleep monitoring, alarm clock, and text message reminder are all good;
2. Long battery life, don't worry about charging problems;
3. The waterproof function is good, under normal circumstances not frequently taken off;
4. The APP is fully functional and interactive.
Shortcomings
1. The ring is too large and does not look good on a thin arm.
2. It is easier to touch and often light up
3. It is not very convenient to remove rice grains for charging
4. Can't keep the display lit, there will be a delay of a second or so when you look up, waiting for the screen to be silly;
5. The notification of the wristband of the incoming call SMS does not display the number, and the mobile phone notification will not show the specific APP.
6. The alarm is turned off a bit weird. The official saying is that you are afraid to close and touch buttons are delayed, but sometimes you touch the touch buttons.
Although the price of the millet bracelet 2 generation 149 is almost twice as expensive as the one generation, it also brings screen and heart rate functions. Regardless of product, function, experience, ecology and other aspects, the millet bracelet 2 is undoubtedly the most expensive price. Excellent products, of course, if you want to buy or rely on hand speed and luck.
