The Xiaomi Mi Band 7 brings numerous innovations to the fitness tracker world while staying reasonably priced. Moreover, compared to its direct competitors, the Huawei Band 7, the Fitbit Charge 5, and the Garmin Vivosmart 5, the health features of the Mi Band 7 are on a reasonable average.
The Fitbit Charge 5 is the undisputed champion when it comes to health tracking. However, even though the Mi Band 7 can now analyze blood oxygen saturation on the spot or when resting, there is a sensor that is still missing: the temperature sensor.
Announced numerous years ago, the Mi Band 7 can still not measure body temperature. To date, very few smartwatch manufacturers offer such a feature that is more complex than it seems. Even Apple had to cancel the release of the temperature sensor for the Apple Watch 7 due to software issues.
Only the Fitbit Charge 5 comes with a temperature sensor, and the measures are unavailable on the spot. Instead, the variations in the skin temperatures are displayed according to a baseline defined during the first couple of days when wearing the band.
Getting a reliable measure of the core temperature through the analysis of the skin temperature is still a distant goal. According to 9to5mac, even though the Apple Watch 8 may introduce such a feature, developing a reliable algorithm remains challenging.
One of the main hurdles to overcome is that the skin is highly dependent on the exterior temperature.
Huami owns Amazfit, and as an early investor in the company, Xiaomi has an exclusive partnership to manufacture its smartwatch and fitness trackers. Hence, significant overlaps are found between the technologies used by the makers.
Considering that Amazfit already offers external and skin temperature sensors in their GTS and GTR series, it is only natural to think that the Xiaomi Mi Band will bring such temperature measurement capabilities at one point.
Unfortunately, to date, the Xiaomi Mi Band 7 is still unable to measure temperature. So we may have to wait for the Mi Band 8 or even the Mi Band 9.
Nevertheless, with the Mi Band 7 adding a blood oxygenation sensor and upgrading its heart rate monitoring sensor, Xiaomi is making significant progress. We look forward to what the future will bring.
