Performance issues can be a common annoyance for iPhone users, especially those with older models. Over time, devices tend to slow down, particularly after Apple’s annual iOS update in September. However, a change is on the horizon for 2026.
Recently unveiled at WWDC in California, iOS 27 brings a host of new features, including a smarter Siri, enhanced Apple Intelligence, improved photo editing tools, and customizable Liquid Glass appearance. Notably, Apple is also touting significant performance enhancements with this update.
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 set to increase by up to 70%, while AirDrop transfers will be up to 80% quicker.
Excitingly, the performance boost isn’t limited to the latest iPhone 17 Pro Max. Through a feature called the CPU scheduler, even older models like the iPhone 11 and iPhone 12 will benefit from increased speed and smoother functionality.
The CPU scheduler optimizes device performance by prioritizing the app currently in use, rather than distributing power evenly across all loaded applications. This dynamic adjustment promises a superior user experience.
While the actual impact remains to be seen, Apple expresses confidence that iOS 27 will prolong the usability of aging devices and potentially eliminate the urge to upgrade perfectly functional iPhones.
Apple elaborated, stating that “Improvements across platforms push key system capabilities forward so everyday tasks feel faster, smoother, and more enjoyable.” Although the release date is yet to be confirmed, iOS 27 is expected to launch in September.
