iOS 27 makes older iPhones faster
Apple's first iOS 27 beta reveals performance improvements that also benefit older iPhones back to the iPhone 11. Tests and reporting (via Wired) show tasks like saving PDFs, switching lock screens and Apple Music playback run faster after the update. Measured gains in early tests include apps launching up to 30% faster on an iPhone 11 Pro Max, Airdrop transfers up to 80% faster on an iPhone 16 Plus, and the photo gallery opening up to 70% faster on an iPhone 15 after capturing a photo. Apple achieves these gains through changes to the CPU scheduler, though the company has not disclosed exact technical details. Not all iOS 27 AI features (Apple Intelligence) will be available on older devices. The article quotes IDC on how extended device support affects upgrade incentives and device resale value.

iOS 27 Boosts Performance on Older iPhones
Apple's iOS 27 first beta is available and includes under-the-hood changes that improve performance on a wide range of iPhones, including older models back to the iPhone 11. Early tests and reporting (Wired) show faster app launches, quicker AirDrop transfers, speedier photo gallery opening after capture, and smoother common tasks such as saving PDFs and switching lock screens. Apple’s changes appear to involve adjustments to the CPU scheduler. IDC’s Francisco Jeronimo noted longer update support increases device longevity and resale value, though some iOS 27 AI features will still be limited on older devices.
iOS 27 arrives — some Apple AI features need newer iPhones
Apple’s iOS 27 update will be available on all devices that supported iOS 26, including iPhone 11, and is claimed to improve performance on older devices. However, several advanced features of Apple’s new "Apple Intelligence" suite — including the enhanced, personalisable AI Siri voices and improved dictation — will be limited to the very newest hardware. At WWDC 2026, Apple software chief Craig Federighi said full-feature support requires iPhone 17 Pro/Pro Max or the iPhone Air, leaving iPhone 16 models without the complete set of AI capabilities despite earlier marketing. The article also notes regional rollout differences (the EU will see some Apple Intelligence features on Mac first) and that the original Apple Watch Ultra will not receive watchOS 27.
Apple Announces iOS 27; Features Vary by iPhone
At WWDC 2026 Apple announced iOS 27 and confirmed that not all new software features will be available on every iPhone. The update supports devices back to iPhone 11, but advanced 'Apple Intelligence' capabilities (including personalized Siri voice and enhanced dictation) are limited to the newest hardware. Apple lists iPhone Air, iPhone 17, 17 Pro and 17 Pro Max as able to run all features; iPhone 15 Pro/Pro Max, the iPhone 16 series, 16e and 17e will receive Apple-Intelligence features with certain limitations (no Siri voice personalization, no simultaneous front+rear FaceTime streaming). Older models (iPhone 11–15 and iPhone SE 2/3) get the iOS 27 update but without Apple Intelligence. Siri AI is not initially coming to Europe, and Apple indicated possible future price increases for hardware. The article was published 2026-06-18.
