Apple has seeded the fifth developer betas of iOS 27 and iPadOS 27 for testing as the company continues to refine its next-generation operating systems ahead of their public launch this fall.
iOS 27 introduces a significant overhaul to the iPhone experience built heavily around Siri AI and Apple Intelligence. The digital assistant now utilizes a more conversational interface capable of drawing on personal context and maintaining onscreen awareness to interact with active content. Apple is also testing a dedicated Siri mode inside the Camera app for Visual Intelligence, alongside expanded generative tools in Photos, Safari, and Shortcuts.
Beyond artificial intelligence, the operating system includes structural and visual refinements. Users can manually adjust the transparency of the Liquid Glass interface to improve readability, while an updated CPU scheduler helps apps launch faster and improves overall battery efficiency.
Registered developers can install the latest firmware over the air. To get the update, open the Settings app, navigate to General, select Software Update, and ensure the developer beta option is turned on.
