Xiaomi quietly works on the successor of Mi Band nicknamed Mi Band 1s. According to a list from Taiwan's National Communications Commission, the notebook will include a heart rate monitor.
The Mi Band 1s carries the same design as its predecessor with three LED lights at the top of an aluminum hood. The heart rate sensor is located on the back of the notebook, which is in constant contact with the wrist of the user.
Based on the NCC's list, we can only expect Xiaomi to launch Mi Band 1 in the near future. We will keep an eye for more details on the device in the future.
