The Apple Watch Series 8 expected to arrive in Q3 2022 was rumored to feature body temperature measurement, but a report earlier this year claimed an Apple Watch with a body temperature sensor is not coming for at least another year. However, popular analyst Ming-Chi Kuo now says the Watch Series 8 with body temperature measurement could still happen in H2 2022.Apple Watch Series 7
Kuo says last year's Watch Series 7 didn't feature body temperature measurement because the measurement algorithm failed to qualify before entering EVT (engineering validation test).
Getting the algorithm right to produce accurate results is important since a smartwatch can't support hardware for core temperature measurement and has to rely on skin temperature, which quickly varies depending on outside environments.
Hence, if the algorithm meets Apple's quality requirements before the Watch Series 8's mass production begins, the smartwatch will come with body temperature measurement, else we'll have to wait longer for an Apple Watch that can measure body temperature.Apple Watch Series 8's leaked render (Source: LeaksApplePro)
The analyst further said that Samsung is also facing similar challenges with its Galaxy Watch 5, and the smartwatch might not measure body temperatures due to algorithm limitations.
Still huawei watch 3 series has a body temperature
Very true, but health pros won't agree with the benefit part. I personally would not trust any watch not even a proper sports watch something as important as blood preasure etc. I'd get medical grade stand alone and monitor from the watch l...
Apple truly needs to figure out how to include the blood pressure sensor for the apple watch. This would give them a true edge and benefit millions.
