The Mi Band 2 does much of the same as its predecessor–track movements, measures sleep, monitors your heart rate, and much more. However, this new model has an OLED display, which will show you your step counts, heart activity and the current time.
Largely because of the OLED display, your Mi Band 2 does take a hit to battery life. The original Mi Band was able to last around 30 days on a single charge, but the Mi Band 2 will only make it to 20 days.
Xiaomi has a June 7 date for when the Mi Band 2 will be available to buy. It’ll be available in black, blue, green, and orange. The wearable will cost interested consumers $23 ($7 more than the original model), and there’s currently no word whether we’ll see this band outside of China.
