Apple is preparing to unveil watchOS 27 at its WWDC 2026 conference on June 8th, with expectations of a range of improvements related to health, artificial intelligence, and satellites, along with tweaks aimed at enhancing the overall performance of Apple Watch.

watchOS 27 will introduce health enhancements and new AI features for Apple Watch.

Apple is adding satellite features and performance and stability improvements.

New updates are coming to heart rate monitoring and battery life.

New watch faces and expanded Apple Intelligence capabilities are also included.

Recent leaks and tech reports suggest that the new update will bring more gradual changes than a radical overhaul. This year, the company is focusing on addressing technical issues and improving stability, along with adding features that expand the smartwatch's capabilities for everyday use.

Regarding health and performance features in watchOS 27,

tech journalist Mark Gurman discussed new improvements to heart rate tracking within the watchOS 27 update, without revealing the full technical details of these modifications.

Heart rate monitoring is one of the most frequently used Apple Watch functions, especially given the large number of users who rely on the watch to track their daily activity and health. Therefore, the new improvements are expected to focus on increasing the accuracy of readings during workouts or in situations where movement changes rapidly.

Information also indicates that Apple is working to improve system responsiveness and reduce power consumption, which directly impacts battery life and the smooth operation of apps on the watch. This comes at a time when modern operating systems are facing significant pressure due to the addition of artificial intelligence features and advanced tasks.

Apple is expected to release the first developer beta immediately after the conference, with the public beta arriving in July. The final version is slated for release to all users in September, coinciding with the launch of new Apple devices. Apple continues to expand its use of artificial intelligence across its various devices, having introduced several features in watchOS 26 that are linked to the Apple Intelligence platform when paired with iPhone 15 Pro and later models.
