The numbers behind "faster"
Apple has a habit of announcing performance improvements in percentage terms during keynotes, but iOS 27's figures are more specific than usual. Tom's Guide and MacDailyNews report the numbers shared from the stage by Craig Federighi: apps launch up to 30% faster, photos appear in the camera roll up to 70% faster after capture, and AirDrop records an 80% improvement in transfer speed.
The main mechanism behind these gains is an intervention on the CPU scheduler — the component that decides how to distribute workloads across processor cores. Apple claims to have optimized this layer to reduce latency across all supported models, including the iPhone 11. WiFi/cellular handoff has also been improved, with smoother transitions between networks.
A "refinement year" in numbers
These figures neatly describe iOS 27's philosophy: not a major redesign or a wave of novel features, but systematic infrastructure work. For iPhone 11 or mid-tier model users, the perceived gain could be meaningful in daily use. For those already on iPhone 16, the effect may be less dramatic. Either way, the AirDrop and photo loading improvements are universal across all supported devices.
