Kuo: Apple Watch Series 7 Missed Body Temperature Monitoring Due to Algorithm Problems, but Feature Could Still Come to Series 8

Apple canceled plans to add a body temperature sensor to the Apple Watch Series 7, but the feature could come to the Apple Watch Series 8 instead, according to reputable analyst Ming-Chi Kuo.

Apple Watch Body Temperature Finished
In a thread of tweets, Kuo explained that Apple originally intended to offer a body temperature measurement feature with the ‌Apple Watch Series 7‌ models, but the company shelved the plans when the body temperature algorithm it had developed failed to meet requirements before the device entered the engineering validation testing (EVT) phase last year.

Kuo believes that the upcoming ‌Apple Watch Series 8‌ could feature body temperature monitoring, providing "the algorithm can meet Apple's high requirements before mass production."

The problems Apple has experienced relating to body temperature measurement purportedly relate to the fact that skin temperature quickly varies based on the environment, and since a smartwatch cannot monitor core body temperature using hardware, the feature is heavily dependent on an algorithm that produces accurate results.

Kuo added that Samsung is experiencing similar challenges with body temperature measurement, noting that the Samsung Galaxy Watch 5 may not come with a body temperature monitoring feature due to algorithmic limitations.

Both Kuo and Bloomberg's Mark Gurman have previously discussed how the 2022's Apple Watches were likely to offer body temperature monitoring capabilities, but rumors related to the feature have quietened in recent times. Kuo's comments today appear to raise further doubts around whether the feature will actually debut with the ‌Apple Watch Series 8‌ later this year.

I went from a S0-watch to S6. Some updates, a little faster and a few gimmicks like EKG and Oximeter - but essentialy it still feels like a minor upgrade to me - probably going to wait for S10-S12 for the next one.
Unless you stayed at watch OS 2.x, I’m calling you a liar.
For me, 3.x was a performance killer on my S0. Every touch took seconds to react.

There’s no way the watch 6 doesn’t feel faster unless you just use it to tell time.

I have a S3... I think It'll be at least another generation or two before a worthy/needed update.

Even if they are not super accurate but they can just provide an indication that something might be off I would buy this for my mother right away.

I went from S2 to S5 and it’s night and day. The series 2 was so slow it was laughable, and the battery only lasted about half the day. I love my S5 but am still hoping to upgrade to the S8 if there are some worthy changes. I decided to skip the S6, so when the S7 was discovered to be essentially the same as the S6 I decided to skip the S7 too. Really hopeful S8 brings something new to the table or at least a faster processor and better battery life.
