The 2014 annual new product launch conference officially released the Xiaomi mobile phone 4. In comparison, the Xiaomi bracelet, which costs only 79 yuan, seems to be just a supporting role. However, when Xiaomi bracelet was released, Lei Jun promised a grand vision of smart home, making Xiaomi bracelet not only a supporting role, but a key to smart home.
In terms of packaging design, Xiaomi bracelet still continues its consistent style. Simple kraft paper is enough to provide protection for long-distance express delivery.
Relevant parameters are introduced on the back. The waterproof grade of Xiaomi bracelet is IP67, which is also a standard feature of smart bracelet. The connection mode is Bluetooth 4.0, and the battery capacity is 41mAh. In terms of device requirements, Xiaomi bracelet requires Xiaomi mobile phones with Android 4.4 and above and supporting Bluetooth 4.0. Since the official app cannot be downloaded at present, it cannot be tested whether it is compatible with other brands of mobile phones.
There is a special charging cable and a guide inside the Xiaomi bracelet package.
The Xiaomi bracelet is actually divided into two parts: the core and the bracelet. The wrist strap is made of American Dow Corning TPSiV material, which has the characteristics of UV resistance, antibacterial, anti allergy, and has good elasticity and comfort. In addition, the Xiaomi bracelet has a variety of wristbands, which are suitable for different use scenarios and combinations, and has a variety of color choices, which will be provided later.
The core surface is made of all aluminum alloy, and the metal surface is 1mm thick. The metal surface of the core uses 12 processing processes, including stamping, polishing, fine milling, laser micro piercing, UV glue injection and other processes. The core has three groups of indicator lights to display reminders according to different functions.
Xiaomi means that the Xiaomi bracelet has passed the rigorous wear environment test, can work normally at - 20 ° C~70 ° C, and can resist impact for 1.2 meters. It has corrosion resistance after being coated with Vaseline for 24 hours. At the core of Xiaomi, there are quite a few high-tech technologies. For example, Xiaomi said that the Xiaomi bracelet uses the most power saving military motion sensor, which is produced by American ADI Company. It is the acceleration sensor with the lowest power consumption, which saves more than 5 times more power than similar ones.
Xiaomi bracelet uses the DA14580 low-power Bluetooth. 0 chip produced by Dialog, and has an 8mm extremely narrow lithium battery with a capacity of 41mAh, which can run the bracelet for 30 days. This endurance is quite shocking, and we will focus on testing in the future.
In terms of functions, the functions realized by the Xiaomi bracelet are basically the functions realized by the sports bracelet, such as recording daily exercise data and calories consumed, recording sleep data and alarm clock reminding functions. Of course, the most important and interesting thing is that the Xiaomi bracelet and Xiaomi mobile phone can be used together to unlock the bracelet. In fact, it is judged through Bluetooth connection to avoid unlocking. The actual experience will be presented later.
