With the threshold of market access getting lower and lower, since the smart bracelet began to appear in the market, there have been a variety of smart watch products, many brands have emerged one after another, eye-catching but also cross eyed. In addition to internationally renowned manufacturers such as pebble and apple, the domestic Weile brand has recently launched a color touch heart rate style - Weile Xiaohei 3.

As an outstanding smart watch R&D manufacturer in China, it has accumulated enough experience and R&D strength since the first generation of products. What surprises can Weile Xiaohei 3 bring to us this time?

>>>Packaging and appearance

‍

‍ When I just received the express delivery, the yellow outer package made me think that this was the only package of Weile Xiaohei 3. But more environmentally friendly, right?

‍

‍

‍

But in fact, this is just the first layer of protective packaging. The real packaging box of Weile Xiaohei 3 is lying quietly in it. The fixing and packaging methods used are almost the same as those of the iPhone purchased on Apple's official website. This packaging can well fix the goods and play a very good role in protection. The sense of class has also multiplied.

‍ In addition, a special paper bag is attached to the bottom of the package. The large logo indicates that Weile Xiaohei is inside. Of course, it is also a matter of pride for Beier to have such a bag containing Xiaohei as a gift.

‍ Xiaohei naturally packs in black, and the three colored bars also indicate that Xiaohei 3 seems to be different?

‍

The assembly method of Xiaohei 3 provides a method of easy pulling, which can tear the package without any other metal tools. The way of opening the goods is also the most important part of the consumer's feeling. Goods that ignore small details are also doomed to be a good product, aren't they?

‍ ‍ ‍

The hollowed out WE LOOP is introduced to the eyes. The paper package contains the product manual and other contents. Below it is placed the small black 3, charging base, charging line, and the strap's packaging box. They are placed in order, and the black color is also quite textured.

Of course, in addition to the charging base and the standard body, the small black 3 comes with a watch strap, and the charging line also has a metal mounting. Buyers can paste it on their favorite objects.

‍

The small black 3 is made of super wear-resistant glass, and is surrounded by DLC diamond carbon film metal. It can be worn for a long time and be as bright as new. The strap is soft, and the detachable design facilitates the replacement of personalized strap.

>>>Features

‍

One of the most important update functions of Xiaohei 3 is that it is equipped with a heart rate sensor, which uses the current mainstream green light photoelectric transmission heart rate detection method. This method is composed of two green wavelength light-emitting LEDs and a photosensitive sensor. Its principle is based on the change of light transmittance caused by the density change of blood in the arm blood vessels when pulsating. It can continuously measure the heart rate (during exercise), calculate the average heart rate, record the maximum heart rate, etc. The metal contact charging mode is adopted, which is easy to charge with the charging base.

So now it is also carried by Apple Watch, which is also a very mature heart rate detection method in the current market. Compared with AW, there is little difference between the two. The accuracy of Xiaohei 3 is relatively good.

‍ The meter body adopts a symmetrical button design, which also allows the small black 3 to be easily worn by left and right hands (the display mode can be changed in the program sequence). This design also facilitates many right-handed users. However, the key is slightly soft and the key range is short. Sometimes it feels that it has been pressed or not, but it is not stiff. Once you are familiar with this button, you can operate it well.

‍

‍

The strap is designed with many holes that can fit most wrist dimensions. The outer surface of this high-intensity Corning gorilla is also very bright and smooth.

‍

‍

This time, the weight of the small black 3 is only 36g, which is very light to wear. Compared with other similar products, the small black 3 is also the lightest. In addition, the color touch screen and heart rate sensor also make the small black 3 very competitive among similar products at the same price. In addition, the small black 3 adopts a very round watch body design and has a certain radian, which can fit the arm well and will not produce a feeling of pressing the hand.

Press and hold the button on the right to start the machine. I believe you can also see that different small black 3 has been matched with a new 1.28-inch 8-color MEMORY LCD, which has a resolution of 176 * 176, and can also be lit as often as the ink screen.

‍

The right button can enter the main menu interface, which is divided into three screens, while the left button can enter the watch status interface to conveniently display information such as power. It is worth mentioning that the Xiaohei 3 supports touch operation at the same time, and it is capacitive touch. The memory of the system combined with ARM CORTEX M4F core and 96K RAM system is 2.5MB. Through the technology accumulation of several generations of products, the system and touch response of the Xiaohei 3 are very sensitive and smooth.

‍

‍

In addition, Xiaohei 3 continues to support a good waterproof level of 50 meters, which is no problem in daily life. Of course, enthusiasts can also wear it for swimming.

>>>App experience

‍

Weile's mobile app can be easily downloaded from the mobile app store, and the interface color matching design is clean and coordinated. In addition to mobile phone number login, you can also directly login through WeChat or QQ account. The functions and icons displayed on the main interface are clear and easy to understand. It is not difficult for IOS users to get started, because the health of AppleWatch also provides similar interfaces such as target information.

‍

Of course, logging in to Weile Xiaohei 3 for the first time requires manual association. Through the device page, the app can automatically find Xiaohei 3 after opening Bluetooth. The association process is very simple. After success, the watch function setting page will be displayed, providing a lot of function options, such as custom adding schedule reminders, setting message push, and of course, the important function of changing the label. The sports interface displays the sports related data records, while the daily walking data is displayed on the first page, and the personal page displays the summary data of sports information, as well as the options to associate with WeChat, QQ and Apple health data, which also basically meet the needs of users to share sports data. It's a lot of fun to play with friends.

‍

After several years of accumulation, Weile Xiaohei has accumulated rich label resources and provided personalized color label. Thanks to the new color screen adopted by Xiaohei 3, the display effect is more pleasing than that of the previous generation. The backlight of the small black 3 can be set independently by the left and right hands. Thanks to the fact that the small black 3 equipped with a 9-axis sensor is also very sensitive when it is lifted to unlock. Basically, the visibility of the small black 3 is good during the day, and the backlight is not required. At night, it is particularly convenient to lift to unlock and light the screen. The automatic detection of heart rate can also be turned on or off manually to save more power, but actually the endurance of Xiaohei 3 is extremely excellent. The official data of standby is 40 days, and it can be used for up to 48 hours after charging for 5 minutes. This also leads me to know that Xiaohei has not been charged until now, and the remaining power is more than 60%. This is also one of the things I think is better than Apple Watch. It feels great not to charge every day.

The system of Xiaohei 3 is updated in a timely manner. It has been updated twice since it arrived. Each update may also have new small functions added. The latest one has added the anti harassment function for incoming calls. It is also very practical. The notification of Xiaohei 3 is very good. The content of IOS built-in applications and third-party applications can be fully displayed, and the shock of Xiaohei 3 is very obvious. It is difficult to ignore a notification, which is much better than my apple watch!

The daily health data interface shows the summary of steps, sleep, and exercise types of the day. The results are intuitively matched with the corresponding icons and evaluation results, so that users can easily see their own health records.

You can also view the data reaching the standard on the day through the calendar interface. The running data is displayed in an independent tab page - the sports interface. However, the track needs to be matched with the mobile terminal to record GPS data. Otherwise, the track cannot be recorded. The pace, heart rate and other information are displayed in great detail, which is very helpful for running enthusiasts.

‍ >>>Summary

As a well-known smart watch R&D manufacturer in China at present, Weile has released many products, and each product has received very good feedback from the market. The Xiaohei 3 released this time leads many domestic similar products in terms of hardware convenience, and has very good price competitiveness with foreign similar products. The color display screen is equipped with the outer screen of Corning Gorilla, and the heart rate sensor is also equipped. The engineering design of the watch also fully considers the wrist wear, and the weight is well controlled. The wearing comfort is very good. After several generations of product iterations, the system performance ability of Xiaohei 3 is very excellent. It has rich personalized settings, rich label resources, and smooth touch without jamming. The notice display and timely vibration effect make the wearer easy to use.

However, Xiaohei 3 does not support the expansion of application app functions. Although it is a little pity, Xiaohei 3 has already met the needs of users in terms of its own functions, so it will not become a very short board. Moreover, the coordination with the IOS system is also very good, so it is not a problem for Apple fans to replace the applewatch with such a smart watch. If you need a smart sports watch, I believe that Weile Xiaohei 3 will not disappoint you.
