The Apple Watch Series 8 may not bring a slew of upgrades that earlier rumors prattled about, but it could have one health feature allowing users to measure their body temperatures. However, it all depends if the upcoming flagship wearable passes the internal tests.

On his Power On newsletter, Mark Gurman talks about past information related to the Apple Watch Series 8, including one where he painfully reminds readers that the smartwatch will arrive with the same SoC present on the Apple Watch Series 7 and Apple Watch Series 6. Fortunately, one change, according to him, is the addition of a body temperature sensor, but if you were hoping for accurate readings, you will be disappointed.
