iOS 27 makes iPhones faster, with no older models excluded from upgrade

Apple has unveiled iOS 27, its latest operating system for iPhones, at the WWDC 2026 developer conference. A key highlight for users is that no older iPhone models will be phased out, ensuring all devices capable of running iOS 26 can be upgraded to the new version.

Beyond the anticipated Apple Intelligence features and a new "Siri AI," iOS 27 introduces substantial system performance enhancements. Apple stated that through extensive bug fixes and underlying optimizations, users will notice a tangible increase in speed during daily operations, leading to a smoother and more responsive iPhone experience.

Quantifiable improvements include app launch speeds that are up to 30% faster, photo loading times after shooting that are up to 70% quicker, and AirDrop transfer speeds that can be up to 80% faster. These advancements mean that not only the latest iPhone models will benefit, but older devices will also experience a significant boost in performance after upgrading.

The compatibility list for iOS 27 mirrors that of iOS 26. This means the entire iPhone 11 series and iPhone SE (2nd generation) and newer models are eligible for the upgrade, providing continued support for a wide range of devices.
