The typically sub-$50 Xiaomi Smart Band 8 launched with the standard elongated, skinny AMOLED fitness tracker display type (albeit with a more novel range of accessories that can convert it into a smart pendant or even a smart shoe-clip) 1 year and 1 day ago today (April 19, 2024). Nevertheless, the OEM has yet to even start teasing a next-gen Smart Band 9 at this point.
However, it is definitely on the way - according to some of the latest rumors, at least. It is thought to have 2 variants (possibly differentiated on the basis of NFC support as usual), although only 1 of them has just re-appeared as a novel Xiaomi device on the regulatory circuit.
The Xiaomi "Smart Band 9", or M2345B1, has now been acknowledged as an actual member of its series this time by both the United Arab Emirates' TDRA and Indonesian Telecom, thereby suggesting that it will indeed join the vanilla 8 and newer, improved 8 Pro on the market soon.
