The next operating system for iPhones, 'iOS 27,' has been released, supporting iPhone 11 and later models, and improving features such as faster photo loading and search.

Apple's annual developer conference, WWDC26 , was held on Tuesday, June 9, 2026, at 2:00 AM JST, and iOS 27 was announced during the keynote address. iOS 27 continues to support iPhone 11 and later, and includes re-tuned Liquid Glass readability as well as faster photo loading and search functions.

Version 27 will be released for iOS, iPadOS, watchOS, tvOS, visionOS, and macOS.

Furthermore, the readability of Liquid Glass has been readjusted. You can now adjust the transparency using a slider bar.

The sidebar extends to the edge of the window. Liquid Glass transparency is also applied to the sidebar, but the color of the sidebar icons is preserved.

Additionally, Liquid Glass will be incorporated into the design artwork of the app icon.

Furthermore, fundamental elements such as memory usage, CPU usage, network processing, and display rendering were thoroughly investigated and optimized for speed. App launch times are up to 30% faster.

New photos appear in your Photos library faster by up to 70%.

File browsing and file transfer speeds from iPad to external drives are improved by up to 80%.

File browsing and transfer in Finder on iPadOS are up to 5 times faster.

They also mentioned that they've been working to further improve the responsiveness of older iPhones. When using an iPhone throughout the day, even when performing many tasks simultaneously and requiring immense processing power, the CPU scheduler, a critical system component that manages CPU resources across the entire workload, ensures that the right tasks are executed at the right time.

It's now possible to extend support to older models, going back to the iPhone 11. In other words, iOS 27 will be supported on the iPhone 11 and all other iPhone models, just like iOS 26.

Additionally, the system can now intelligently switch between Wi-Fi and mobile data connections, and the entire chat no longer freezes when sending large photos via iMessage until the transmission is complete.

Furthermore, the search functionality has been completely restructured across 'Spotlight,' 'Photos,' and 'Mail.'

Updating to iOS 27 will apparently build a search index on your device.

You will now be able to participate in shared albums in full resolution from both Android and Windows devices.

Healthcare apps now allow you to track menopause and the period surrounding it using cycle tracking.

AirPods feature a custom EQ, allowing you to further personalize the sound of your AirPods.

And parental controls have been enhanced. Existing Apple accounts can be converted into child accounts. Parents can now manage screening times, accessible content, viewing time, and who their child can talk to on devices linked to their Apple account.

Next, Apple announced 'Siri AI,' which integrates with the new Siri, as part of its Apple Intelligence line.
