I’m concerning about the Mi products all the time. As a huge Mi fan, I have Mi router、Mi band 1、Mi Battery、Mi Air Purifier, Mi Power Bank, Mi Action Camera…
Compared with the battery capacity of Mi first generation’s 45mah, Mi second generation has increased to 70mah. The official claim that with the new technology, even if the screen is added, its standby still reaches 20 days. The product’s waterproofing is the same as the original, Ingress Protection Rating 6 and 7. So bathing and swimming aren’t bad for the machine. After professional media profiling, Mi second generation seem to have a better waterproof.
The second layer : a silicone ring, a charging line, and a manual.
You can see that the new charging cable is different, wider and larger. And it doesn’t apply to Mi Band first generation. The silicone ring is also tighter than before and it may not come off easily.
Obviously,the silicone bracelet second generation is better.
Raising hand to display. Because it is a new function, so the firmware is not perfect. It often delays obviously, usually around three seconds. And it often fails. Many times raising the hand does not show any contents. Of course it can be awakened at any time if you touch it, but it’s not that convenient.
Touching the button twice, it will change to the number of steps today, then the number of miles, following is the heart rate, and of course there are more options in the settings of the ring.
Friends who used the first generation are familiar with this interface. The second generation also has the basic setting, but is added to the function of lifting the wrist to bright screen. And it has the same heart rate detection of sleep aid as the Mi Band 1 light version. The feeling is that the data displayed is more accurate, but it will significantly shorten the standby time. This is a trade-off between data accuracy and standby time.
Recommendation Level: 4 stars out of 5 stars. Mi Band 2 does it’s job at this price.
