I. Introduction
First of all, I would like to thank the aunt for the chance to test this opportunity. It is really surprising. I also like the product of this test, Xiaomi Bracelet 2, and she is full of expectations. (Feeling is not only I did not expect it, it is estimated that Zhong Jun did not expect this public test actually there will be two give up.) So this time to go all out to write this evaluation, please have the following protagonist of this evaluation: gorgeous The dividing line. wrong! Millet Bracelet 1 (hereinafter referred to as mi1), Millet Bracelet 2 (hereinafter referred to as mi2), Happy Heart hr Bracelet (hereinafter referred to as Le hr).
Second, appearance characteristics & wearing comfort
(Hint: The corresponding explanatory text below the figure)
Out of the box
This time out of the box did not like to see the value of the tape to the point, directly put poisoning first. The basic components are visible from the box: rice, charging cable, wristband, manual.
2 appearance details and millet bracelet 1 contrast
Here we only compare two generations of millet bracelets, because it may be carrots and vegetables have their own love, everyone is not the same as the aesthetic, the author believes that music is mainly focused on the hardware and its functionality, in the design looks a lot worse (even with the mi1 The ratio is also somewhat inferior.) So here only the appearance of the mi1, mi2 music bracelet in the back of the functional comparison will be described in detail.
2.1 rice grains:
The rice grain is the main part of the bracelet, and the rice grain of mi2 is larger than the rice grain of mi1. The grain of mi2 can be said to be fully upgraded in appearance. Positive 0.42 inch oled display, curved glass is significantly deeper, cd lines of the touch is also the design of the highlights of its design, while the mi1 magnesium magnesium alloy surface is the only advantage is more suitable for the engraving of some patterns up .
2.2 Wristbands
Mi2's wristband will be replaced with the mi1's wristband buckle and the same as the touch button cd lines clip pin than the mi1 to be fine, buttonholes smaller, and the wristband is more flat than the mi1, the touch is more delicate.
2.3 overall effect
The overall effect should be mi2> mi1> Lehr, but here's one more thing to note about the two-point design of mi2. First, mi2 glass is not scratch-resistant, and two scratches appear within two days of use. Second, the cd-grained touch keys and wristband buckle, this cd pattern is relatively easy to dirty, in order to maintain its continued shining or much rub.
3. Comparison of wearing comfort
Mi2 is actually not comfortable to wear because of the addition of this tasteless heart rate sensor (why the chicken would say later).
First of all, sweating at this time is severe and it is easy to store sweat, so it is not appropriate to wear too tight.
However, problems arise if the belt is sent over, since the contact area of ​​the heart rate sensor and the skin is smaller than that of the entire back surface of mi1. So even if the vibration sometimes does not feel too obvious, in fact, mi2's vibration amplitude is larger than mi1.
There is weight, three bracelets mi1 lightest, followed by mi2, Le hr heaviest. However, in the actual wearing process, mi2, and Le hr are the same, can all feel the existence of the bracelet, but generally do not care when they bring mi1.
So in terms of wearing comfort, I think it is mi1>>mi2.
Third, the hardware parameters
We have four aspects of the hardware for this icon (chart produced by echart). It can be seen that the mi2 is more balanced and the Leh is notably outstanding in terms of endurance.
1. Lifetime
The official data is mi1: 30 days, mi2: 20 days, and music hr: 7 days. In actual use, mi1 and mi2 meet the standards while Le hr is sometimes quite a week. Because Le hr's display is more than double mi2, and Le hr internal algorithm should also have some problems, the bracelet is easy to miss. Another point is the difference in heart rate sensors. This will say for a while. Mi2 can achieve 20 days of battery life is not easy, first of all like it, but this life is based on the premise of sacrifice in the accuracy of heart rate.
2. Heart rate sensor
The first one in the picture above is mi2 and the second is Lehr. It can be clearly seen that Lehr's sensor brightness is higher than m2, which is one of the reasons for m2 power saving. But in fact, reducing the sensor power will sacrifice the accuracy of the heart rate measurement and prolong the measurement time. This is particularly evident in practical use. Le hr is faster when scrolling to measure heart rate. It is generally around 3s and the meaning of a bit of real-time data is that the heart rate changes at any time. It is estimated that the heart rate is measured for a period of time and then displayed. The heart rate of the mi2 must wait about 6 seconds (or it must be in the immovable condition), so care should be taken in the children's shoes in this aspect of the heart rate sensor. It can be said that mi2 made the heart rate a more tasteless function. As for accuracy, since there is no professional instrument for the time being without accuracy-related information, the heart rate data measured by the two bracelets can reflect the trend of change.
3. Waterproof and dustproof
All three wristbands are IP67 waterproof and dustproof. There is no problem with a typical hand bath, but swimming has not been tried. If you have tried it, you can tell it in the comments.
4. Function points
This is somewhat related to the hardware here, because some of the function points are closely related to the hardware. For example, mobile phones transmit data to each other and their heart rate. Le hr has more features than mi2, such as caller ID. There was also trajectory tracking in the past. I do not know why in this new version. I think that these functions should not be a problem for Xiaomi's development team. It depends on whether the latter can be improved.
Fourth, software features and details
The author here would like to apologize to everyone because the box of music that I am interested in is not being thrown (the QR code on the box is connected to the music and motion app). I can't connect to the sports app, so the app section can only be illustrated here. Mi1 and mi2 are different.
1. The main function
This picture comes from the Internet, because the hand is relatively unrefined in the function point icon did not shine like a sample point, simply find a good display on the Internet.
This is the five displayable function points of mi2: time, heart rate, mileage, number of steps, remaining battery power
There is also a number not shown: heat
2.app control
Adjustable display in its millet sports app
Newly added heart rate interface
Mi2 has 2 more function points than mi1 (the standard reminds mi1 also has adjustment in different positions) Seated reminding and Do not disturb mode is very suitable for white-collar office use. Very much used features, like it. The alarm clock can still set up three alarm clocks. Here, we must mention the three wristbands. The most powerful one is the sense of happiness. However, the sense of tremor is strong enough to be excessive... The alarm clock of Lehr cannot stop. Mi1 and mi2 can stop the alarm by tapping or touching the key, but Le hr is always shaking ... ... shock to your wrist numb. This also leaked out some of the problems of Lehr's lack of soft power. At some extremes, the details were not in place. The millet's details are handled well.
Because the display mi2 has been added more controllable items than the mi1, there are some details to say that the next one is to lift the wrist light screen. In fact, mi1 also has feedback but it is not good, often unsuccessful. Often missed, mi2 can guarantee 100% success based on few false-positives.
There are more to say here because the millet system of skills to millet bracelet blessing, millet bracelet as long as the phone and millet remain connected, you can automatically unlock the password-free screen. However, mi1's experience is a bit bad, often failing or losing the password. The success rate of mi2 has obviously improved a lot.
3. Step function
Mi2 and Lehr can display steps from the phone due to the display. I recorded changes in the number of steps in the two bracelets for the next day and found that there was not much difference between the two bracelets. In most cases, the score was slightly higher than mi2. Listening to the official saying that mi2 upgraded the algorithm to judge the number of steps, it will filter out some steps, but the actual use gap is not great.
V. Summary
advantage:
Yan value in the same price bracelet is the leader
Long life time
Touch operation is simple
Detailed features in place: such as the direction of the display, lift the wrist bright screen, detail settings
Disadvantages:
Heart rate function is not good enough, in fact, you can increase the battery to increase the power of the sensor. Because you can still feel the presence of the bracelet.
It is not comfortable to wear, and the wristband is easy to collect sweat.
Suggest:
Since there are already physical buttons, you can add more interactive features. For example, when the phone rings when you call, determine whether the headset is attached. If you directly connect the headset, you can automatically answer the call by touching the physical key to avoid the phone.
Can increase the point display function.
The last real beast
Looking forward to seeing the next meeting with the kings on the platform
