The Apple Watch is left without a temperature sensor

The body temperature sensor was one of the rumored new features that the new Apple Watch model, Series 7, would include, however. according to Ming Chi Kuo, we will have to wait for series 8.

Bad news for those who were waiting for the new Apple Watch: one of the new functions that were expected in the model that will arrive after this summer has been removed by Apple. The reason? Failure to meet strict company quality requirements

, which has decided to postpone the inclusion of the body temperature sensor until next year. The information was given by Ming Chi Kuo in a series of tweets in which he explains the exact reasons for this delay.

Apple’s problems with measuring body temperature have to do with the fact that skin temperature varies rapidly with ambient temperature. Since Apple cannot measure core temperature (the “right one”), this feature was based on measuring skin temperature and applying algorithms so that depending on different factors, such as ambient temperature, the actual body temperature can be estimated.

Core temperature is the temperature inside our body. Since we cannot easily measure the temperature of our interior, we generally use the temperature of other more accessible areas such as the armpit, mouth, eardrum and rectum, since their values ​​are very approximate. None of these areas are close to where we place our Apple Watch

the one where you can measure the temperature directly is at the wrist, an unreliable place for this measurement, which is why proper algorithms are needed to give us more reliable measurements.

Apple has failed to ensure that its algorithms allow reliable measurement of body temperature, so before launching a malfunctioning feature, he preferred to postpone its implementation until next year’s Apple Watch. As Kuo added, Samsung is having the same issues with the Galaxy Watch 5.
