And look at the millet bracelet on sale in the market, the highest degree of enthusiasm for millet bracelet 4 and millet bracelet 4 NFC version of the two products. It can be said that compared to the previous generation (Xiaomi bracelet 3), it has more functions (Xiao-ai classmates, access card, public transport card, smart home control, offline Alipay payment) at the same time also made a lot of upgrades in hardware (better view of the color screen, the resolution of 120x240 new AMOLED screen, etc.).
But one thing that needs to be mentioned over here is that Xiaomi Bracelet 4 doesn't have Xiao Ai Classmate, smart home control, public transportation card, access card, etc., and these features are only available in the upgraded Xiaomi Bracelet 4 NFC version. But this is also a lot of people who want to get into the Xiaomi bracelet 4 tangled point, these extra features practicality in the end is not high, there is no need to choose the more expensive NFC version. For people who have not used a smart bracelet and want to get one to play a little, millet bracelet 4 NFC version in the end is worth buying is also a question. The author experienced the millet bracelet 4 NFC version of a week, may be able to bring you some reference.
Operating logic: easy to use and humanized
To use the Xiaomi bracelet 4 NFC version, you need to download the Xiaomi Sports APP to bind and set up, the process is very simple, the bracelet close to the phone can be bound and set up. First of all, I would like to start from the operation logic part of the story, because a smart bracelet of the first operation mode is touch screen operation, in such a small piece of screen if you want to reach a more convenient and comfortable operation, then its operation logic is certainly to pass.
There are two ways to wake up the bracelet, wake up by lifting and wake up by touching the Home button. Wake up by lifting can be set to open all day and open at regular intervals, and there are standard and sensitive sensitivities, which are recommended to be set to the sensitive mode, and the author's test found that the screen lights up much faster when lifting in the sensitive mode.
After waking up the bracelet, the main interface is displayed, showing the year, month, day, time, power, steps, the overall operating logic can be understood as the main interface to start the left and right slide can be switched to the four functions, respectively, Ai Ai classmates, Alipay Payments, music playback, left and right application switching channel is interoperable, when you slide to the music playback and then continue to the right slide back to Ai Ai classmates interface.
Swipe up and down for the same reason, the default apps are status, notifications, sports, heart rate, card pack, weather, more, more contains do not disturb, alarm, music, stopwatch, countdown, find phone, phone mute, Alipay, dials, settings and other infrequently used functions. If you want to open Xiaoxia when you are in the interface below the main interface, you can only go back to the main interface (slide or touch the Home button), and then slide left again. It is worth mentioning that these functions can be hidden within the Xiaomi Motion APP, which can be said to be more humanized, and the sliding of the screen during operation is also very smooth, no lagging phenomenon occurs, and the animation of the transition is also very comfortable to watch.
In addition, millet bracelet 4 NFC version of a **** have seventy-two kinds of dials to choose from, can be regarded as more on the market in the smart bracelet products, in addition to their own set of custom dials. After you choose the clock display location you can upload your own picture to set the dial, in terms of personalization is still relatively free. But personally, I think the seventy-two dials are just a few of the better looking ones, and the rest just feel like they're a bit of a patchwork.
Basic function part: good but there are slots
After finishing the logic of operation, I believe that you also have a rough understanding of the functions of the millet bracelet 4 NFC version, after a week's experience I love it and hate it, in the convenience of my life at the same time there are some flaws, and listen to me slowly to say.
Notification
Message notification is a feature that many smart bracelets have, and as a standard feature of smart bracelets, it's no longer uncommon, but this feature has also become a point of demand for many consumers to choose a wearable device. Because as the most commonly used function, a smart bracelet display effect, look and feel, the number of words displayed becomes particularly important.
It can be seen that when receiving multiple messages, the whole screen is able to display 35 words, displaying more content. And the whole screen is really good, after all, in the screen equipped with a 0.95-inch, 120x240 pixels resolution AMOLED color screen, its display effect is still good. By the way mention that the received message can not reply directly through the smart bracelet, but is able to view more than one, just need to slide down and slide up to switch.
When receiving an incoming call alert, the bracelet will also perform a vibration feedback, and the screen will display the caller's information. You can choose to mute and reject the call on the bracelet. This is a very useful feature, for example, when your phone is in your bag during outdoor sports, you can see the caller's information and decide whether or not to answer the call.
But from a personal point of view, I still want to complain about the notification function of the Xiaomi bracelet 4 NFC version.
1, WeChat phone call prompts no timeliness, such as other people give you a WeChat phone call, and then the phone prompts when the bracelet will not be real-time reminder. Only after the missed call WeChat receives the message of missed voice call, the bracelet will synchronize the message to tell you that there is a missed WeChat call. In fact, for me, nowadays, I basically use WeChat to make phone calls, and seldom use SIM card for dialing, so if WeChat phone call reminder can't be synchronized in real time, it's still a little inconvenient for daily use.
2. The resting speed of the bracelet is too fast, about five seconds, and after the resting screen, the message is retained in the first priority display of the bracelet for only five seconds. This means that after you receive a message, if you don't have the first time to check the bracelet, then after five seconds you need to wake up the screen to check again. If you don't wake up the screen to check the message within five seconds after the resting screen, then you need to wake up the screen in three more steps - slide to find the notification function - tap the notification or pull out the phone from the pants pocket.
3, I used to bind the bracelet phone for millet's own millet 9 SE, in nearly a week of use, the message notification failed twice, phone notification failed three times. If you encounter this situation should restart the millet movement APP, restart the bluetooth connection can be restored to normal, in general this part of the function is still to be improved.
Weather and status
For me, I don't use the weather and status functions of the bracelet much in my life. But in general the weather part of the display is still very perfect, you can see the weather conditions, temperature, air quality, etc., and you can also see the current location.
Weather can show the weather conditions within seven days, and through the bracelet comes with Xiaoxi students can also query the weather at any time, not only the current location of the weather can query the weather can also query the weather outside of the field, whether there is rain, how much wind can be query. This is still relatively convenient.
And in the status function, you can see the number of steps, distance, calories consumed after wearing the bracelet, and also see the number of sedentary reminders, the number of sedentary times can be set through the millet movement APP switch, open can be set to remind the time period, but I still turned off the function, after all, after turning on the function to sit for an hour will vibrate you a little bit or more annoying, because even if the reminder of sedentary. Because even if the reminder of sedentary. The probability that the user will not get up to move the body ~
Music control, exercise, sleep monitoring and heart rate
Millet bracelet 4 NFC version of the sports function supports outdoor running, indoor running, cycling, walking, exercise, swimming pool six sports modes, the exercise process will record the exercise time, steps, distance, heart rate, speed, stride rate, stride frequency and so on. The handheld can be opened in sports mode, millet sports APP can also be opened in sports mode ~
For example, when running or walking, every kilometer will be a vibration reminder by the way will show the average speed of this kilometer movement, allowing users to understand the approximate movement data, if you are a daily exercise, you can according to the weight change and exercise length, distance data To make an adjustment to the intensity of their own exercise, and in the anti-touch part of the millet bracelet 4 NFC version also do a good job, as shown in the above GIF picture, you need to long press the Home button or return to long press the pop-up pause icon in order to end the movement.
And in the swimming mode, when you open it will allow you to set the length of the pool, the default has 25 meters and 50 meters, on this basis there is also an additional custom distance, after the end of the exercise mode bracelet will show the distance of swimming, the number of trips, paddling rate, swimming posture, etc., which is anti-touch design is still more detailed, you must slide up + down to be able to unlock the bracelet. (PS: in the water is not able to operate the millet bracelet 4 NFC version).
And in the measurement of the accuracy of the number of steps I also tested, the test I walked a hundred steps, millet bracelet 4 NFC version of the number of steps displayed 97 steps, a difference of three steps. Equivalent to a 3% error, but this is a normal phenomenon, because from the technical point of view it is not possible to achieve 100% accuracy, any bracelet will have an error, just say how to reduce this error. But at least from the point of view of the performance of the Xiaomi Bracelet 4 NFC version, it's not bad. As for the detection of heart rate is accurate this side because I do not have a professional medical equipment testing, so there is no detailed test.
But in general, there is no need to deliberately observe how many steps, how the heart rate, how many calories consumed in the exercise, these are not as much as running ten minutes of steps, more exercise to really, the data of the bracelet is just to give a reference.
And sleep monitoring part of the millet bracelet 4 NFC version I also tested, in the sleep because someone called me to wake me up, get up to answer the phone to hang up the phone to sleep the whole process of about two minutes or so, the bracelet also gave me recorded down. And reference data is also more, you can see the specific deep sleep and light sleep time and recent statistics sleep quality table.
And for many people who like to listen to songs when exercising, before acquiring the millet bracelet 4 NFC version may envision the following scenario, wearing headphones and listening to songs running and then the phone can be completely placed in the bag, switching songs, adjusting the volume, checking the news can be completed in the bracelet above. But you may think too much, millet bracelet 4 NFC version in the open sports mode can not be switched to other functions, not to mention the possibility of switching music (but can receive messages and call alerts). But it's okay we can record the exercise on the Xiaomi Sports App and then use the bracelet to perform other operations. Then the problem comes, in the actual use of the author that the millet bracelet 4 NFC version of the function of the control player is relatively chicken ribs, switching music, increase or decrease the volume will have about one to two seconds of delay. This delay in operation will make the author very upset.
Overall the music player control is pretty good in the functional part, you can pause and play, you can see the name of the song, you can adjust the volume and switch songs. But it would be nice to get rid of the latency issue.
Intelligent part: small love classmates highlights a lot
With the popularity of millet ecological, small love classmates also exists in millet's own various products, such as cell phones, smart speakers, etc., this time also came to the millet bracelet 4 NFC version, but it should be mentioned that the bracelet is a mute version of small love classmates, the interaction way for the user to send voice commands, and then small love classmates text feedback.
And in terms of functionality, Xiaomi bracelet 4 NFC version of Xiao-ai classmates may not be as smart as Xiao-ai classmates on other terminals, after all, limited by the device. However, for the user, the bracelet is also just a personal device, its focus is not artificial intelligence, more will be to assist the phone function and sports aspects. In my opinion, from the nature of the device Xiaomi bracelet 4 NFC version of the small love classmates has also been enough.
The most commonly used interaction scenarios in daily life with Xiao-ai classmates is to ask Xiao-ai classmates how the weather is, whether it is raining, whether the wind is strong, adding, subtracting, multiplying and dividing, and what are the most recent good-looking movies, etc., and the answers are relatively straightforward through the way of the text presented to the author. But let me think the best use of a function is the reminders, reminders can be through the bracelet, using voice to let the small love classmates set up, you can also set up manually on the millet movement APP.
Some people say you don't have reminders on your phone? I would like to say that the bracelet is a more personal device than the phone, I used to use the phone's reminders will occasionally miss the phone reminders, because it is likely to ignore the few vibrations in the pants, and the phone is sometimes not always carried. But millet bracelet 4 NFC version is different, is directly on the hand, vibration down no matter what you are doing you will feel.
This also gives an insight into the use of this, it is best to set the vibration mode of the reminder in the millet movement APP settings to customize the default vibration mode is easy to be ignored, in the use of the default vibration mode at the beginning of the author to use the default mode of vibration, missed the reminder of the matter of the two times, but in the author customize the frequency of a vibration, every point to the point of the vibration of the bracelet will be received very clearly and clearly reminded.
In fact, in terms of the millet bracelet 4 NFC version, I think its biggest selling point in addition to the small love classmates is the smart home control, which is also millet played a very smart hand, the advantages of their own smart home ecosystem embodied in a very good. At least from the present point of view of this kind of personalized bracelet is considered a good solution for the entrance of the smart home control, very convenient.
I also tested the millet bracelet 4 NFC version of the control of the smart home part of the overall building of the smart home as shown in the figure above.
And in the actual use of the effect is also quite good, directly through the millet bracelet 4 NFC can open the TV, turn off the TV, open the air conditioning, turn off the air conditioning, such as summer in the garage is ready to go up the stairs can be through the bracelet of the small love classmates ahead of the home of the air conditioning to open, I think it's still very convenient, and the small love classmates in the receipt of the instruction is also very fast to deal with. As shown in the moving picture above, it takes about two seconds to complete the required operation.
While the Xiao-ai classmates on the Xiaomi bracelet 4 is very useful, but I also have to complain about the place, sometimes call up the Xiao-ai classmates is a second to open, can be used smoothly. But there are times to open the small love classmates at least wait four to five seconds or so it will come out, this instability also gives millet hand ring 4 NFC version of the small love classmates some points, and in the voice recognition rate is still to be improved, once in the outdoor dinner I called the small love classmates to remind the eight o'clock in the evening to remember to watch the game, because of the interference in the vicinity of the sound is more, in the set up of the seven or eight times after all did not set up a successful, no help! The phone out of the open millet sports APP for manual settings.
Alipay, access control simulation and bus card function: third-party support needs to be strengthened
In addition to the Xiao-ai classmates, the highlights of the Xiaomi bracelet 4 NFC version of the Alipay offline payment, access control card simulation and bus card function, in terms of the bus card to support the 13 bus cards (Beijing-Tianjin-Hebei interconnection card, Jiangsu traffic card Suzhou, Lingnan Tong (traffic joint), Shenzhen Tong, Wuhan Tong, Hefei Tong, Jilin Tong, Guangxi traffic card, Chang'an Tong, Green City Tong, Harbin City Tong, Qindao Tong, Taizhou public **** traffic card) and the country's 218 city bus (specific reference to the Xiaomi official website - smart wearable devices - Xiaomi bracelet 4 NFC - public transport city), part of the city to open the card, if you need to open the card fee of twenty to thirty dollars, but because the author is in the city of Chongqing does not support the Public transportation function, so there is no relevant test. However, in the past few days, I read the online information and the evaluation of users, millet bracelet 4 NFC version of the bus card function should be quite good, and I hope that millet can be popularized as soon as possible, after all, this part of the application scenario for consumers is one of the points of purchase, if you do a good job, but also increase the competitiveness of the millet bracelet market.
And in the access card simulation of this part of the function is also the author set up the most difficult, first of all, millet bracelet 4 NFC version does not support the simulation of encrypted access card, only to support the market is not encrypted and the frequency of 13.56MHz door card, which makes the author's head hurt. It can be said that most of the door cards on the market are encrypted, so the author's home neighborhood access card is no exception, after testing is not directly simulated to the bracelet.
The good thing is that the millet bracelet 4 NFC version has another set of solutions, you can use the bracelet to open a millet blank card, and then go to the property for authorization and access control entry. I opened a blank card after the use of the gatekeeper to give a mother card entry, the results of the entry was successful. Unfortunately a *** entry of four door access control, but only one door can be used. However, after using the author feels is really cool, the bracelet can open the door as soon as you lean on it ~
Overall millet bracelet 4 NFC version of the access card simulation is indeed still to be supported by the third party, I also searched for related issues on the Internet, a lot of netizens have said that this feature is a good feature, but limited by the third party. First of all, to ensure that the community's access card is non-encrypted 13.56MHz (but most access cards are not), if not, we must go to the property office to enter the authorization (this step to ensure that the property can give you to carry out the operation, there are relevant technology and machines). If the above two steps can not be reached, then either like the author of the luck to find the mother card, or you can search the Internet for a specific solution.
And as one of the selling points of Alipay offline payment is still relatively good, need to mention that the Alipay on the bracelet is the need to recharge and then use, as shown in the picture Alipay a separate small program smart device, in which the binding after recharging, rushed in the money can be unbundled at any time to take out. Guess the reason why the use of recharging is also in order to reach the offline payment, in actual use can be said to be good and bad, a **** used three times, of which two are very comfortable and convenient to sweep away. And once the salesman swept four or five times before sweeping on, after all, the screen is too small sometimes there are still some small problems.
Charging and battery life: performance is enough
And in the charging and battery life I feel is more than enough, Xiaomi bracelet 4 NFC version is equipped with a 123mAh battery, the official claim that the duration of up to twenty days, but this twenty days of battery life only support Xiaomi bracelet 4 standard version, while the NFC version of the duration of the NFC version was not informed, so I also conducted a test.
First of all, I have to complain about the millet bracelet 4 NFC version of the charging can not see the percentage of progress, the bracelet can not see even if the millet movement APP can not see, but finally a record, I started charging from 3% of the power at 4:40 pm until 6:25 pm charging to 100% of the power, a total of one hour and forty-five minutes.
And in terms of battery life, I also made a record, first of all, open the heart rate detection is very consuming power, so I turned on the first day of the heart rate monitoring and set up every minute detection, during the period of use of sports walking mode twice, each time about fifty minutes, twenty-four hours of power consumption of 23%.
On the second day, I turned off the heart rate monitor, and used the same exercise walking mode twice for about 50 minutes each time, consuming 10 percent of the power in 24 hours. If you look at this rate of consumption, you'll only be able to use the device for about four days with the heart rate monitor on, and ten days with it off. But it's still enough, after all, the Apple Watch is a one-day charge.
In addition, in the process of using the author at first thought it was like Apple Watch only need to connect to the phone Bluetooth on it, and then found that the millet bracelet 4 NFC version not only to connect to the phone Bluetooth, but also to keep the millet movement APP running in the background, otherwise it will be missing part of the function, out of curiosity, I also did a small test.
If you only turn on Bluetooth to close the millet sports APP, you can only receive phone notifications, love classmates and message notifications will say goodbye to you. But think about it, after all, nowadays the phone memory do also quite big, background more reserved an APP is not a big problem.
Writing in the end
Using the millet bracelet 4 NFC version of a week's time, I still use the way the phone has produced a certain change. When I received a message while focusing on doing something, I don't need to open the phone to view it, and directly use the bracelet to view it. If it is not a very important message will choose to ignore and then continue to do things, avoiding the opening of the phone and thus affecting my concentration. And although the voice recognition rate is not as good as I thought, it is also very convenient to set reminders and control smart home appliances at any time. The access card can also be thrown away, a brush can enter the neighborhood, with millet fingerprint lock for use out of the house can not bring anything.
Overall Xiaomi bracelet 4 NFC version in the convenience and freshness brought to me at the same time there is a little flaw, not smooth enough to control the music, the occasional failure of the message notification, can not be used for public transport card, but overall the advantages outweigh the disadvantages, after all, the price of this bracelet is also only 229 yuan, at least I feel that this bracelet is affordable to this price. If you are a handheld millet bracelet 3 want to upgrade the latest model of the user, or no smart bracelet is ready to get a play a user, then I think the purchase of millet bracelet 4 NFC version or not lose.
