The year passed and I looked in the mirror and watched my happy belly. I discovered that it was time to pay attention to my body, and I thought of buying a sports bracelet. After an meticulous comparison, Xiaomi Bracelet 2 was selected. The price is not expensive and the evaluation is not bad.
Millet (MI) Millet Bracelet 2 Intelligent Sports Heart Rate Monitoring Incoming Call Reminder Sedentary Reminder LED Display Time Display Waterproof Pedometer Without Feet Wristband 159 Yuan Millet Bracelet Second Generation Jingdong Direct Links View Encyclopedia II Jingdong Logistics is to force, the order was issued at eight o'clock the evening of the previous day and was delivered the next day.
The packaging box looks very millet, white simple style, the front is the product image of the bracelet, and the back is the product-related information.
Open the box, "rice" is set in the center of the box, the black is very thorough.
Open the top floor. The bottom layer is a wristband, charging cable, and instructions.
Let's take a look at the appearance of the core part "rice". "Grain" has a mirror design on the front. The following is a touch button with CD lines. The upper part has a small screen displaying information. The size is 0.42 inches. The material is OLED. The screen is almost integrated with the panel.
The back of the "rice" is the chip that monitors the heart rate and the logo of the millet.
At the bottom of the "rice" are two copper contacts for charging.
According to the instructions, "rice grains" must be inserted from the back of the wristband. Somehow, "rice grains" and wristbands are closely attached. Please refer to the above picture for the effect. As for aesthetics, this subjective thing is not evaluated by me.
Third, the function evaluationDownload the millet sports app. After setting, you can connect the wristband to the app. Note that you need to turn on the Bluetooth and location functions of the phone when you connect.
1, step count
The pedometer is one of the basic functions of the Millet Bracelet 2. Compared to the first generation, the built-in new-generation accelerometer is said to be more accurate. The APP can present daily step information in a very intuitive form, at a glance.
2, heart rate
Another basic function of the millet bracelet 2 is heart rate measurement. After understanding, millet's heart rate sensor measures the heart rate through the photoelectric measurement method, and irradiates the blood vessel with the LED light and the photosensitive photodiode for a period of time. The heart rate is measured according to the blood's change of the green light absorption amount. Before measurement, in order to measure accurately, APP will remind you not to walk while measuring, and wear the wristband away from your wrist.
3, monitor sleep
Millet bracelet 2 can record the whole process of sleep, and statistics on the corresponding sleep quality at each moment. The left graph above shows the statistics of sleep status on a certain day. Horizontal represents the time axis, dark blue represents deep sleep, light blue represents light sleep, and yellow represents awake state. You can see that I spend more than three hours in deep sleep each day.
Heart rate assisted sleep monitoring can be enabled in the wristband setting, which can improve the measurement accuracy, but it will increase power consumption and reduce battery life. If the requirement is not very high, it is recommended not to turn it on. After all, high frequency charging is troublesome.
4, remind function
Various types of reminder functions can be set in the app. The wristband will be alerted in the form of vibration.
5, bracelet display content settings
The display of the wristband defaults to the time, number of steps, and heart rate. Through the settings, information such as mileage, calories, and remaining power can also be added. In addition, the time display style can also be changed.
6, raise your hand bright screenThis feature is very practical, eliminating the need to touch the touch screen to light up the screen every time, and occasionally raising your hand to see the time is very convenient.
Milli Bracelet 2 uses a 70mA lithium battery. Officially stated that the components are all low-power components (low-power OLED display, second-generation low-power Bluetooth 4.0, low-power acceleration sensor + heart rate sensor), and life is about 20 Days or so.
The frequency of use of these two days is roughly as follows: lift the wrist 20 times or so, connect the mobile phone 3 times, and use it mildly. The average power loss was about 6% a day, which means that the battery life is about 17 days. It is basically consistent with the official propaganda and is still relatively satisfactory. This kind of endurance ability is just like a counterfeit watch compared to a smart watch. Nowadays, many smartwatches on the market have been absolutely forbearing.
Fifth, wear feelings
1, millet bracelet 2 and the human body contact with a soft skin-friendly material, breathable and sweat-proof, good comfort;
2, small size, light weight, rice size, see above, weight only 7g, no pressure to wear it up;
3, protection level IP67, can play a protective role against short-term soaking, can be worn when washing hands or showers, to avoid the frequent removal of the troubles, very convenient;
Six, summary advantages: 1, long life time;
2, IP67 protection level;
3, APP function, data statistics clear and intuitive;
4, comfortable to wear;
Disadvantages: 1, the unhappy rate monitoring sleep record is not accurate enough to get up a few times in the evening but have been counted into light sleep state;
2. It takes a long time to measure the heart rate, and it requires a static measurement.
Overall, millet bracelet 2 is a good upgrade to meet the basic needs of the average user, but the price is not expensive, it is worth a try.
