Bloomberg and The Wall Street Journal reported that Apple's next watch, the 8th generation, will include a temperature sensor and a new "Pro" category for extreme sports.
Apple's newest smartwatch could have a temperature-sensing feature, but currently Bloomberg reports that it will not be able to provide you with a specific reading, it's more likely to say if you are might be experiencing a fever and then suggest consulting other appropriate sources like a doctor.
Bloomberg is reporting that the new rugged Apple Watch Pro will have 7% more screen space and a larger battery than the current largest Apple Watch so it could compete well with the new watch faces released by Apple. There are new details in the story about what this new watch will be called, for instance, and what its competition will face.
Ross Young's Twitter feed suggests a third Apple Watch size could come this year. It is unknown if that means the display or size may change on the Series 8, but there has been discussion about upgraded displays internally.
The Series 8 will have a new low-power mode, that allows for apps and features to run in order to conserve battery life. Bloomberg also reports that the Apple Watch Pro will have an enhanced battery life.
