Sleep Tracking Just Got Smarter: iOS 26.4 Brings New Insights and a Familiar Feature Back
Apple's latest iOS update, 26.4, is here, and it's bringing some exciting changes to the Health app, particularly for those who prioritize their sleep. But here's where it gets interesting: alongside a brand-new feature, Apple is also reinstating a previously removed one, sparking a conversation about the company's ongoing legal battles.
Average Bedtime: Your Sleep Schedule Under the Microscope
For sleep-conscious users, iOS 26.4 introduces an 'Average Bedtime' metric within the Sleep section of the Health app. This feature goes beyond simply tracking sleep duration; it analyzes your bedtime patterns over a two-week period, providing a clearer picture of how consistency (or lack thereof) impacts your sleep quality. Think of it as a gentle nudge towards establishing a healthier sleep routine.
Blood Oxygen Returns to the Spotlight (Sort Of)
And this is the part most people miss: iOS 26.4 also marks the return of blood oxygen level monitoring to the Vitals graph in the Health app – but only for iPhone users in the U.S. This feature, previously available on the Apple Watch, was removed due to a legal dispute with Masimo, a company alleging patent infringement related to blood oxygen sensing technology. While Apple successfully reintroduced blood oxygen monitoring on iPhones in August 2025, the Apple Watch remains without this functionality in the U.S. market.
A Step Forward, But Questions Remain
The reintroduction of blood oxygen monitoring on iPhones is a welcome development for health-conscious users. However, the ongoing legal battle with Masimo raises questions about the future of this feature on the Apple Watch. Will Apple find a way to resolve the dispute and bring blood oxygen monitoring back to its wearable device? Only time will tell.
Beyond Sleep and Oxygen: What Else is New?
iOS 26.4 is currently available to developers and public beta testers, with a wider release planned for spring. While sleep and blood oxygen are the headline features, it's likely that this update includes other bug fixes and performance improvements, as is typical with iOS releases.
Looking Ahead: Apple's Busy 2026
Apple's 2026 is shaping up to be a busy year. Rumors suggest the imminent release of the iPhone 17e and a new iPad Air with an M4 chip. Additionally, a mysterious 'special Apple Experience' event is scheduled for March 4th in New York, London, and Shanghai, leaving fans speculating about potential new product announcements.
