Performance issues are a common frustration for iPhone users with older devices as they typically experience a decrease in speed over time, especially after Apple releases its annual iOS update in September. However, the upcoming iOS 27 release in 2026 is set to change this narrative.
Recently announced at WWDC in California, iOS 27 brings various enhancements, including a smarter Siri assistant, improved Apple Intelligence, better photo editing tools, and new customization options for the Liquid Glass appearance. Notably, Apple promises a significant performance boost with this update.
Apple claims that iOS 27 will enable apps to launch up to 30% faster, resulting in a smoother everyday user experience. Additionally, the company pledges that photo loading speeds across devices will increase by up to 70%, while AirDrop transfers will be up to 80% quicker.
What sets this performance upgrade apart is its inclusivity. The new CPU scheduler feature will not only benefit users of the latest iPhone models but also enhance the speed and fluidity of older devices like the iPhone 11 and iPhone 12.
The CPU scheduler optimizes performance by allocating maximum processing power to the active app on the screen, rather than distributing resources evenly across all loaded applications. This dynamic adjustment of performance levels ensures users enjoy a superior device experience.
While the true impact of iOS 27 remains to be seen, Apple is confident that it will prolong the lifespan of aging devices and eliminate the need to upgrade iPhones that are still in good working condition. According to Apple, these enhancements aim to accelerate key system capabilities, making everyday tasks faster, smoother, and more enjoyable.
Although an official release date for iOS 27 has not been announced, it is anticipated to be available in September.
