Your aging iPhone will feel a little more responsive once you download iOS 27 later this year. At least, that’s Apple’s claim. At its developer keynote at this year’s WWDC, the company said its next mobile operating system update brings several platform stability improvements that will make older devices, as far back as the iPhone 11 from 2019, run a little better.
There’s a laundry list of improvements, from faster PDF saving to the camera launching faster when in Low Power Mode. But the main highlights? App launches are up to 30 percent faster—that’s tested on an iPhone 11 Pro Max. AirDrop file transfers are up to 80 percent faster (tested on an iPhone 16 Plus), and jumping into your photo library after snapping a photo will load images up to 70 percent faster, as tested on an iPhone 15.
The iPhone will get smarter about switching between cellular and Wi-Fi networks. Apple has also rebuilt the system that powers search in Spotlight, Photos, and Mail, meaning you should ideally see exactly what you’re searching for on the first try.

Some of these improvements are thanks to optimizations to the iPhone’s CPU scheduler. This is a standard component in operating systems that coordinates work for the CPU, managing the traffic flow of apps and services so that the main thing you’re doing on your iPhone—the thing you’re currently focused on—runs smooth and fast. Apple’s most advanced CPU scheduler is in its latest devices, but the team brought many of those algorithm advancements down to the iPhone 11 in iOS 27.
It’s in Apple’s best interest to keep older devices updated for as long as possible. Francisco Jeronimo, vice president for Data and Analytics at research firm IDC, says consumers don’t want to feel forced to upgrade their smartphone. If they can keep their device for longer, it’s one less worry, and better value for money, especially as we’re spending more on smartphones today than ever before.
“This is a big differentiator between iOS and Android,” Jeronimo says. “Because consumers now know that if they buy an iOS device, it will last longer, and it will retain value at the end when they decide to upgrade. An Android device—after two, three years, depending on the brand—they will not be able to get upgrades anymore. The device will lose value if they want to upgrade, and they will not be able to sell it at a higher price.”
While Apple typically supports its devices for six to seven years, only select Android phone makers like Google and Samsung promise that level of support.
