Apple Watch Series 10 leak reveals improved ECG sensor and new sleep apnea detection feature

There are only a few days left until Apple’s big Glowtime event on Monday, and the rumor mill doesn’t seem to be stopping. While the iPhone 16 lineup will undoubtedly be the main star of the show, we’re also expecting the Apple Watch Series 10 (or Apple Watch X) to be unveiled alongside the AirPods 4. Two new leaks claim that the next-generation Apple Watch will feature an updated ECG sensor that can detect sleep apnea.

Sources familiar with Apple’s plans told 9to5Mac that the updated ECG/heart rate sensor could provide more accurate results, unlocking new features on the Apple Watch Series 10. This confirms a Bloomberg report on Friday that sleep apnea detection, a long-rumored feature that Apple has reportedly been working on, will finally be included in the next line of smartwatches.
