Smart watches have developed rapidly in the past two years, but manufacturers always have choices in terms of function and endurance, such as iWatch The endurance of smart watches such as Moto 360 and ticWatch, which focus on function applications, is quite painful. After all, watches are not mobile phones. More charging in a day will lose the meaning of watches. The other type of smart watches with longer endurance have relatively few functions, mainly focusing on motion monitoring and intelligent reminders. The most impressive one is the Vela smart watch, Xiaohei, who claims to charge only 12 times a year, has now developed into the third generation. What surprises will this Xiaohei 3 released on the treadmill bring to users? Let's see the evaluation of Xiaohei.

The package of Xiaohei 3 is made of all black matte paper boxes. The red, green and blue logo on the front of Weile's logo shows that Xiaohei has entered the era of color screen. The product label on the back and the sealing of the box cover are very humanized. The box can be opened by tearing the notches on both sides.

The inner box is very simple. The upper layer is a very personalized green document bag, which looks very delicate. There are instructions inside. The lower layer is left for the watch body and charging base, and the right is the charging line and strap accessory box.

The small black 3 uses a magnetic contact charging base, but the contacts are distributed on both sides. The strap is designed for quick removal, and it is easy to install and remove. The attached strap is made of TPEE material, soft and light, which is skin friendly. There is a sweat channel on the hand surface, which is not easy to leave sweat. It is said that the small black 3 will later launch standard wristbands for different wearing scenarios High permeability outdoor extreme edition wristband, fitness magic wristband, imitation leather effect wristband, leather wristband and other watchbands.

The whole watch still follows the tough style of the Xiaohei series, but it is more rounded than the second generation Fangzheng. In particular, the upper surface is designed with curved edges. Although it is not 2.5D glass like the Apple watch, it looks more fashionable.

The middle part of the back of the watch is the heart rate detector. At present, watches or bracelets that can measure the exercise heart rate on the market are either less accurate or more expensive. As the main function of the Xiaohei 3, real-time exercise heart rate monitoring is said to be as accurate as a professional heart rate belt. In addition, from the 5ATM logo on the back, the Xiaohei 3 has a 50 meter waterproof level.

Unlike many smart watches, which turn off the screen in order to save power, Xiaohei 3 uses a color Memory LCD. The lock screen interface will not turn off the screen, and the screen will display more clearly in the stronger light environment. Many professional sports watches also use this screen, which is very convenient. The only disadvantage is that the backlight still needs to be turned on in extremely dark environments.

There is an entity key on both sides of the watch. The left side is for cancel or return, and the right side is for confirmation or page turning. Press the left key on the lock screen page to view the status information such as the power of the watch. The right key can enter the function menu, and slide up and down to switch to the motion meter, weather information, and two-dimensional code business card.

Xiaohei 3 connects to the mobile phone APP through Bluetooth, binds the watch on the device interface, updates the firmware, changes the dial, and performs various setting operations. The latest firmware version is 1.8, and its functions have been relatively complete and stable.

As the Xiaohei 3 is a color screen, the picture effect is more vivid, and it has touch screen operation, so it is easier to use than the previous two generations. As a color screen watch, the Xiaohei 3 has a variety of color lock screen patterns, which can show the user's personality. If you can launch the function of self-made dial, it will be even better.

The watch data can be synchronized through the mobile phone APP, and the movement and various data statistics can be viewed. The whole interface is also very clear. The target interface displays the movement and sleep status of each time period of the day in the form of a timeline. Click to enter to view the details.

It can be seen from the separate listing of sports as a block in the APP that Weile has made sports monitoring a key point in the functional development of wearable devices. At present, it can specifically start the sports measurement of running and riding. Moreover, the addition of Xiaohei 3 real-time heart rate detection makes the movement detection function of this smart watch more professional. The detailed interface of sports can see the pace, heart rate, step frequency The accuracy of motion trajectory and other curves, as well as the analysis of motion data, is quite high, and the data can be used in applications such as Happy Running Circle, Yidong GPS, Nike, etc.

The statistics of data include exercise and sleep. According to the daily, monthly and annual periodic column chart, the statistics of exercise monitoring also include the comparison of the previous cycle. The sleep monitoring is also more accurate by obtaining three states of deep sleep, light sleep and wakefulness, which can distinguish late afternoon nap or noon nap, The sleep quality score gives a summary analysis of sleep during the time period.

Xiaohei 3 has ATM5 waterproof grade. Generally, it can be washed and soaked casually. There is no problem with daily waterproof. Swimming and bathing should be OK.

Xiaohei 3 also inherits many practical functions of the previous generation of products, such as message push, daily alarm clock, schedule reminder, call identification, etc., as well as many user-friendly settings, such as wrist flip screen, long sitting reminder, mobile phone loss prevention, remote control camera, etc., can also use Xiaohei 3 to control the music playback of the handset as a stopwatch or timer, which can be a good partner of mobile phones.

In terms of battery life, the nominal life is 40 days. Its built-in 270mAh battery is much larger than that of ordinary sports bracelets. The power consumption of the Memory LCD screen itself is also low. From the perspective of actual use, the power loss is about 26% after 10 days of mild use, which is basically the same as the nominal life. Even users with a large amount of exercise should have no problem using it for a month.

summary

The appearance of the Xiaohei 3 is not outstanding, which is consistent with the practical function positioning of the product. The price is 488 yuan. As a smart watch focusing on sports, its accurate motion monitoring, 40 day long endurance, a change of monotonous color Memory LCD screen, and many practical functions, although these are not black technology, they are so ordinary and simple, But the practical smart watch may be the one you need.
