More details of the Xiaomi Mi Band: you can use it to unlock the phone (more details how later), monitor exercise and sleep quality, and there’s a smart alarm clock. It’s waterproof. Xiaomi indicates a standby time of 30 days, but it’s not clear how long it’ll last when you’re truly using it. But there’s no power-sapping screen, so it should be better than the average smartwatch because it’s a different type of gadget.
The Mi Band is bad news for Fitbit, which charges RMB 899 (US145) for the Fitbit Flex in China. Remember this is just RMB 79 (US$12.80).
For about US$13, hell, I’d try it. That’s an easy entry into wearables.
