Aside from the body temperature sensor, Gurman claims that any additional upgrades to the Apple Watch’s hardware will be “minimal,” and he also suggests that higher-end models may have a better display. Gurman projected last week that the Series 8 processor will have the same level of performance as the preceding S7 and S6 chips, with no upgrade probable until 2023. In terms of health-tracking features on other future products, Gurman believes that the latest model of AirPods Pro, which is supposed to be fitness-focused, will not have temperature or heart rate sensors this year.
