Xiaomi’s design for its Mi Bands has roughly been the same all along. You have a capsule that has all the guts of the Mi Band 3 and a strap made out of thermoplastic elastomer which latches securely onto your hand. The capsule has grown in size and the Mi Band 3 has the biggest one yet in the series. It is curved at the sides and is slightly extruded from the strap when snapped in place. The OLED display is also bigger than the one on the Mi band 2 and it is also brighter making it more legible outdoors.
There are grooves on the side of the capsule which allow the strap to hold it in place. This also helps prevent the capsule from popping out when you are running, something the original Mi Band was notorious for. Xiaomi ships a USB charging cable in the box which can be plugged into any adapter or a laptop to charge the capsule. The Mi Band 3 has a tiny dimple below its touchscreen which is a capacitive button. This button has two functions — a single tap to go back, and a long-tap to accept. Turn the capsule around and you can see the slightly raised heart rate sensor.The Mi Band 3 pairs with a smartphone using the Mi Fit app and Bluetooth 4.2 LE, which keeps the power consumption down. The app is available on both the Google Play Store and the Apple App Store, and it is very easy to pair the band with a phone. When using the Mi Band 3, one can swipe upwards to go through various bits of information. When there is more than one readout available, you will see a scroll indicator hinting that you can swipe right to left to see more.
The Mi Band 3 displays a lot more information than the model it replaces. Apart from the time and date, you can check the number of steps taken, distance covered, calories burned, battery level, a three-day weather forecast, heart-rate, and a stopwatch. You can also switch the ringer profile of the phone (Andriod only), use the band to find your phone, and start recording exercise sessions directly from the band. Pros
