Apple Watch Series 8 Will Feature body Temperature Monitoring
According to well-known analyst Ming-Chi Kuo, Apple canceled plans to add a body temperature sensor to the Apple Watch Series 7, but the feature may appear in the Apple Watch Series 8.
In the latest report from Ming-Chi Kuo, he explained that Apple previously tried to bring body temperature measurement for the Apple Watch Series 7, but the plan was delayed when the temperature algorithm failed to meet requirements before launch.

He expects that, the Apple Watch Series 8, which is scheduled to be launched in the second half of this year, may be equipped with body temperature monitoring, only if the algorithm can meet Apple’s high requirements before mass production.
Apple canceled body temperature measurement for Apple Watch 7 because the algorithm failed to qualify before entering the EVT stage last year. I believe Apple Watch 8 in 2H22 could take body temperature if the algorithm can meet Apple’s high requirements before mass production.
The challenge in implementing precise body temperature measurement is that skin temperature quickly varies depending on outside environments. A smartwatch can’t support core temperature measurement in terms of hardware, so it needs an excellent algorithm to work together.

Furthermore, Ming-Chi Kuo said that Samsung is currently facing the same problem. But unlike previous press reports, he believes the Samsung Galaxy Watch 5 later this year may not support temperature measurement due to algorithm limitations.
Samsung is facing this challenge as well. Unlike previous media reports, I think Samsung Galaxy Watch 5 in 2H22 might not support the body temperature measurement due to algorithm limitations.
