iPhones released in 2019 still support iOS 27.

Contrary to concerns, iOS 27 continues to support iPhones from the 11th generation released in 2019, making older devices run more smoothly thanks to its advanced CPU management.

Apple just announced iOS 27 at the Worldwide Developers Conference (WWDC 2026). Unlike the radical upgrades to the Liquid Glass interface in its predecessor, iOS 27 focuses on improving performance, stability, and resource management. Notably, this update maintains compatibility with all devices that received iOS 26, extending the software lifecycle for models released since 2019.

Optimizing performance for older hardware

At WWDC 2026, Stacey Ford, Apple's Vice President of Operating System Program Management, confirmed that the iPhone 11 series will be updated to iOS 27 this fall. The most significant change is the integration of an advanced CPU management system – a system previously only found on newer models.

"Even when you're multitasking with dozens of computationally intensive tasks, the CPU manager ensures the right tasks are executed at the right time," Ford explained. This improvement promises to fix lag issues on older devices running iOS 26, making them more responsive and smoother.

With this decision, the iPhone 11 is about to enter its eighth year of software support. Meanwhile, contemporaries like the Google Pixel 4 or Samsung Galaxy S10 only receive a maximum of three years of platform updates. In total, iOS 27 will be compatible with 30 different iPhone models, including the iPhone SE (second generation) and its mini versions.

Limitations in artificial intelligence capabilities

Even after upgrading to iOS 27, older devices will not be able to fully enjoy the new features, especially the Apple Intelligence artificial intelligence tools.

Starting with iOS 18, core AI features, including the upgraded Siri virtual assistant, will be limited to iPhone 15 Pro models and later. Furthermore, Apple states that the most powerful on-device AI processing models will be exclusive to the iPhone 17 and iPhone Air series.
