Performance issues have long plagued iPhone users, particularly those with older devices. As time goes on, these devices tend to slow down, especially after Apple’s annual iOS updates. However, a significant change is on the horizon for 2026.
During the recent Worldwide Developers Conference (WWDC) in California, Apple unveiled iOS 27. Alongside enhancements like a more intelligent Siri, improved Apple Intelligence, better photo editing tools, and new customization options for the visually striking Liquid Glass design, Apple also promises a substantial performance boost.
Apple claims that iOS 27 will enable apps to launch up to 30% faster, enhancing the overall user experience. Additionally, photo loading speeds across devices are expected to increase by up to 70%, while AirDrop transfers will be up to 80% quicker.
What sets this improvement apart is that it won’t solely benefit owners of the latest iPhone 17 Pro Max. Thanks to a feature known as the CPU scheduler, even older models such as the iPhone 11 and iPhone 12 will experience enhanced speed and fluidity.
The CPU scheduler optimizes performance by allocating maximum processing power to the active app on the screen rather than spreading resources across all loaded apps. This dynamic adjustment of performance levels ensures a smoother user experience.
Apple anticipates that iOS 27 will prolong the usability of aging devices and eliminate the need for users to upgrade iPhones that are still in good working condition. The tech giant emphasized, “Improvements across platforms push key system capabilities forward so everyday tasks feel faster, smoother, and more enjoyable.”
While an exact release date for iOS 27 has not been announced, it is expected to be available in September.
