Apple Watch Series 8 launch: From large display to body temperature sensor - what to expect

Apple Watch Series 8 launch: The US-based tech giant Apple may launch its upcoming Apple Watch series 8 with a bigger 1.99-inch display and  a body temperature sensor that will let the user know if he or she is running a fever.

"In October last year, analyst Ross Young suggested that the Apple Watch Series 8 could come in three display sizes, reports MacRumors. Now, responding to a query about the rumour on Twitter, Young claims that the additional display size joining the Apple Watch lineup will be 1.99-inches in size diagonally," IANS said in a report. 

According to the report, it seems likely that the 1.99-inch display size presented by Young has simply been rounded up by Pu. A 1.99-inch Apple Watch display size compares to 1.691-inches on the 41mm Apple Watch Series 7 and 1.901-inches on the 45mm Apple Watch Series 7.

The new display size would offer an additional 0.089-inches of space diagonally over the 45mm Apple Watch Series 7, which is almost a 5 per cent increase. The slightly larger display size may relate to the rumoured redesign for the Apple Watch Series 8 with flat edges.

Earlier this year, the leaker known as "ShrimpApplePro", who correctly said that the Apple Watch Series 7 would feature a rounded design like the Apple Watch Series 6, claimed that Apple was working on a "flat front glass display" for the Apple Watch Series 8.

A recent report suggests that the upcoming Apple Watch should be able to detect a spike in body temperature, and then ask you to use a thermometer.  However, the upcoming lower-end Apple Watch SE is not going to have this health feature.

Famed Apple analyst Ming-Chi Kuo also believes the body temperature sensor will make its debut later this year. Previous reports suggested the sensor could also be used for fertility tracking -- shifts in body temperature could help someone determine when they're more likely to get pregnant.

The watchOS 9 will also bring new features, including an enhanced Workout app, sleep stages, a first-of-its-kind Afib History feature, an all-new Medications app and more.

"This fall, watchOS 9 takes the Apple Watch experience to the next level with scientifically validated insights across fitness, sleep, and heart health, while providing users more creative ways to make their Apple Watch their own," Jeff Williams, Apple's chief operating officer, said last month.
