Gearallnews compared the characteristics and capabilities of the two models, so you made the right choice.
Body and strap
Both accessories have interchangeable straps, but a silicone bracelet from Mi Band 2 to the Mi Band 3 capsule will not work. The reason for this is not only another form, but also its increased size. The Mi Band 2 main module has dimensions of 40.3 × 15.7 × 10.5 mm, and the novelty has 46.9 × 17.9 × 12 mm.
As for the straps themselves, the Mi Band 3 is adjustable within 155-216 mm with a total length of 247 mm. The Mi Band 2 is 155-210 mm and 235 mm respectively. That is, the novelty can be approached even by those to whom the previous bracelet Xiaomi was not enough.
Along with the increase in size, the overall weight of the accessory also increased significantly: 20 g versus 7 g. However, Mi Band 3 is unlikely to be felt on the wrist.
Xiaomi Mi Band 2 has IP67 moisture protection, which allows the device not to be afraid of rain, shower and even short dives to a depth of 1 m. The new Mi Band 3 has stepped far ahead: it withstands a water pressure of 5 atmospheres, comparable to a depth immersion at 50 m.
It was the screen that became one of the main differences between Xiaomi Mi Band 3. It was almost doubled: 0.78 inches compared to 0.42 inches for Mi Band 2. The resolution increased proportionally: 128 × 80 pixels versus 72 × 40 for the predecessor. In addition, the display is touchscreen, which allows you to operate the tracker with simple svaypami, and not pressing a special button, as in the case of Mi Band 2.
Also worth noting is the appearance of Mi Band 3 trend 2.5D-glass, which makes the screen panel more streamlined and rounded at the edges. The Mi Band 2 display cover was absolutely flat. As for the matrices themselves, they are essentially the same: they are monochrome OLED panels.
Sensors and communications
Both devices are equipped with a three-axis accelerometer, which is responsible for counting the steps, and a heart rate sensor. The latter in the case of Mi Band 3 has a higher accuracy, confirmed by the certificate ISO-10993-5 / 10.
The novelty communicates with the smartphone via Bluetooth 4.2, whereas the previous model of the tracker supports only Bluetooth 4.0. This improvement should provide an increase in the speed of data transmission and reception.
Another important difference is the NFC chip, which will be equipped with a slightly more expensive version of the Mi Band 3. He will use the bracelet for contactless payment, but Xiaomi did not comment on the support of the Google Pay service at the presentation.
The increased display of Mi Band 3 allowed to significantly expand the functionality of the device. Now all the data on physical activity will be more detailed, the text of the messages should be displayed directly on the bracelet display, and with the incoming call Mi Band 3 will display the name of the subscriber. Mi Band 2, working in conjunction with the application Mi Fit, for all this uses only icons.
Even if at the start Mi Band 3 screen will be able to display only notifications of WeChat and QQ, over time the manufacturer or third-party applications developers will be able to adjust compatibility with instant messengers and social networks popular outside of China.
Also Mi Band 3 offers new widgets, such as weather forecast, and reminders of upcoming events. All other features available on Mi Band 2 are preserved, including sleep monitoring, vibration alarm, unlocking the smartphone.
Due to the appearance of the touchscreen, the power consumption of the Mi Band 3 increased noticeably, but the capacity of the battery increased from 70 to 110 mAh and allowed to maintain autonomy at the same level. The new bracelet, like Mi Band 2, works on one charge for about 20 days. This is more than enough to not carry a wire for recharge.
One of the main features of Xiaomi bracelets has always been a low price, and Mi Band 3 did not become an exception. The basic version of the tracker will cost RS 1800, and the option with NFC – RS 2000y. For comparison: Mi Band 2 started with a mark of RS 1500, that is, the difference is not large.
As it usually happens at the start, the first Mi Band 3 on AliExpress will cost about 1.5-2 times more than the official price for China. That is, it costs at least 3,000 rubles. However, even at this price, the bracelet will surely fly like hot cakes.
There are four main advantages of Mi Band 3 in front of Mi Band 2:
- the best moisture protection;
- the emergence of NFC;
- increased touch screen;
- wide interaction with notifications.
