Apple's iOS 27, expected in September 2026, is rumored to prioritize performance improvements similar to Mac OS X Snow Leopard. Bloomberg's Mark Gurman reports the update will still introduce new features, many centered on Apple Intelligence. The first public beta is slated for WWDC 2026 in June, giving developers months to prepare.

Key rumored upgrades include a redesigned Siri with proactive suggestions and memory of past conversations. An AI-powered Calendar app and a new Apple Health+ subscription with an AI health coach are also expected, potentially using Google Gemini for some backend intelligence. These moves deepen Apple's AI integration across its ecosystem.

Connectivity may see a major leap with reported 5G satellite internet support, potentially limited to iPhone 18 Pro models. Additional satellite features could include Apple Maps via satellite and sending photos via Messages without cellular service. As more rumors surface, iOS 27 appears set to balance stability with meaningful, AI-driven enhancements.
