One of the most popular wearables got a massive upgrade this year with the new Xiaomi Mi Band 2. The first Mi Band was a breakthrough because of its battery life, compact size, and bargain price. Then the Mi Band Pulse added a heart-rate sensor, but took the RGB notification LEDs.

And now - with the Mi Band 2, Xiaomi fans all around the world are finally getting the display they wished for.

Xiaomi's Mi Band 2 keeps the iconic design, but replaces the three LED lights with a 0.42" OLED display. There is also a touch-sensitive key below the tiny screen, which helps you switch between the different notification panes.

Other notable upgrades are the bigger battery (70mAh), improved HR sensor, better motion tracking sensor, and enhanced Bluetooth connectivity. The strap also got a refreshed design.
