Amazfit Band 6 or Mi Band 5 Pro, is expected to have all these missing features. The huawei band, the spO2, measures very accurate and I have compared it with my oxylometer that I use at the hospital were I work as a doctor. For me, if you want to buy something, best of all is the huawei, even from the now Mi Band 5. If and when 5 pro comes out, to see what exactly includes and we can speak again if I believe the same or not.
