Apple internal: Doubts about Siri performance under iOS 26.4
Apple promises a smart Siri in iOS 26.4 – but according to internal sources, the AI system is struggling with serious performance issues.
iOS is Apple's operating system for the iPhone and one of the most widely used mobile operating systems in the world. Unveiled in June 2007 alongside the original iPhone and renamed from iPhone OS to iOS in 2010, the system is introduced every year at WWDC in June and ships in fall with the new iPhones. Since 2025, Apple synchronizes the version numbers of all its operating systems with the calendar year. iOS brings central features such as Home and Lock Screen customization, Dynamic Island, StandBy, Live Activities, Apple Intelligence, the Liquid Glass design, privacy features like Mail Privacy Protection and App Tracking Transparency, FaceTime, iMessage, Wallet, Apple Pay, and deep integration with iCloud, Apple Watch, AirPods, Mac, iPad, Apple TV and Vision Pro.
