You don’t have to spend a lot of money to get your hands on a smart wearable these days. Take Xiaomi’s Mi Band 2. It is a smart bracelet with a 0.42inch display that can track movements, measure sleep, and monitor your heart rate. The device is waterproof. It displays step count, heart activity, and the time.
Since the Mi Band 2 has a display, it has a battery that lasts only about 20 days. The device will go on sale on June 7th in China. Engadget has more on the story.
