Apple Watch 8 early rumor: biggest upgrade ever


A fresh report from an Apple expert sheds light on Apple Watch’s body temperature sensor.

Bloomberg’s Mark Gurman reported last month that the Apple Watch 8 might have a temperature sensor, which would be the first new health sensor for the gadget since the Apple Watch 6 included blood oxygen monitoring.

Ming-Chi Kuo, an analyst for Apple, has raised doubts about the accuracy of the Apple Watch 8’s body temperature sensor. If Apple can make the algorithm precise enough — something it battled with for the Apple Watch 7 — it may still be planned for the next-generation Apple Watch launch, Kuo added.


After failing to qualify before joining EVT last year, Apple dropped body temperature measurement for Apple Watch 7, according to Kuo. “If the algorithm can match Apple’s rigors standards before mass production, I think Apple Watch 8 in 2H22 might measure body temperature.”

It isn’t that it’s difficult to take an accurate body temperature, but rather that the wrist where the Apple Watch rests isn’t a spot that any physician would choose to take skin temperature, if given the option..

Skin temperature changes rapidly in the outside environment, making it difficult to accurately monitor body temperature, Kuo said. To enable core temperature monitoring, a smartwatch requires an effective algorithm to function in tandem with the device’s hardware.


Gurman made it clear that he did not promise that the sensor will be included in the Apple Watch 8 and just claimed that it may come as early as this year. Wearables makers are still making modest progress on integrating more health sensors, but Kuo’s tweets explain why this is happening.

As Kuo points out, Samsung is also experiencing issues with their own temperature sensor. Samsung’s Galaxy Watch 5 may not be able to record body temperature in the second half of this year because of “algorithm restrictions,” he said.

If done correctly, skin temperature may be a useful supplementary indicator for smartwatches, however it isn’t the most engaging health sensor on the market.


As everyone who has had their temperature measured as part of the COVID-19 screening process knows, a high fever may be an indication of disease, too. In fact, the Fitbit Sense and Fitbit Charge 5 both monitor your body temperature overnight to alert you to any irregularities or even the need for additional sleep. both of these.

Fitness monitors may also utilise temperature as a gauge of how well-prepared the body is for activity. While Oura Ring Generation 3 suggests that you take it easy if you notice an unexpected temperature fluctuation, Whoop 4.0 uses its temperature sensors to provide recovery counselling.

As far as health sensors go, it’s safe to say Apple won’t be slacking off when it comes to the Apple Watch 8. Last year, Rockley Photonics, a company specialising in mobile sensors that can monitor anything from alcohol to carbon monoxide levels, disclosed that Apple was its largest client. Just to lend a little more credibility to the present topic, we’ll also include body temperature.


We’ll have to wait until September to find out whether any of them make the cut this time around, when the iPhone 14 is scheduled to appear with Apple’s next wearable.
