- iOS 27 will run on iPhone 11 and other phones released in 2020.
Apple’s latest operating system lists the iPhone 11 as the oldest supported device, while dropping the iPhone X and earlier models. The rollout includes performance tweaks that keep the older A13 chip responsive and preserve battery life. Developers can target the same APIs across a wider hardware range.
This matters because it extends the useful life of phones that are already two years old, cutting down e‑waste and softening the urge to buy a new iPhone each year. It also shows that Apple can extract more efficiency from existing silicon without a hardware redesign.
It’s not a breakthrough, but a modest stretch compared with the tighter cutoffs of past iOS releases.
