iOS 27 Leaks: 'Snow Leopard' Performance Boost, 'Siri Chatbot' and Multitasking for iPhone Fold

Apple's next big iPhone software update is already taking shape, in rumour form, with iOS 27 expected to be unveiled at WWDC 2026 in June and discussed as the release that may finally deliver a smarter Siri and foldable iPhone features originally anticipated earlier. The information comes from a MacRumors roundup of supply chain chatter, analyst claims and feature leaks tied to Apple's next software cycle, much of it still unconfirmed.

MacRumors says Apple had been expected to ship its more advanced Apple Intelligence version of Siri in iOS 26.4, but development problems have slowed that plan and left parts of the overhaul in limbo. The delay matters because it shifts expectations around iOS 27. Rather than a routine annual update, it is now being seen as a second chance for Apple to deliver the AI features it has already teased, though nothing is confirmed and all details should be treated with caution.

iOS 27 and the Foldable iPhone Push

The most concrete shift in the report concerns the long-rumoured foldable iPhone, which MacRumors says Apple plans to launch in September with a 5.5 inch display when closed and a 7.8 inch display when opened like a book. If accurate, iOS 27 will not simply need a fresh coat of paint but will have to scale from a familiar iPhone view into something closer to a compact iPad.

MacRumors says Apple is building larger screen interfaces for the device, with side-by-side multitasking when unfolded and left-hand sidebars in many first-party apps. The report adds that the foldable phone would run iOS rather than iPadOS and would not support iPad apps, reflecting a very Apple approach to a very Apple problem, expansive in hardware but tightly controlled in software. The design is said to use a wider 4-to-3 aspect ratio, suggesting the company is aiming for an iPad-style experience without fully acknowledging it is creating a pocket iPad.

That may be the most interesting part of the leak. Foldables have been around long enough that Apple can no longer present the form factor itself as the novelty. Any novelty will come from whether iOS 27 makes the larger canvas feel coherent rather than awkward, and the report suggests Apple is at least attempting to solve that before the hardware arrives.

iOS 27 May Finally Force Siri to Evolve

Siri remains the real test. MacRumors says some or all of the delayed Apple Intelligence features could slip into iOS 27, while a separate 'Siri chatbot' version is also in development, designed to operate more like ChatGPT, Claude or Gemini. Apple is even said to be working with Google on a custom AI model built with the Gemini team for some of those new capabilities.​

The promised improvements sound substantial. According to the report, Siri is supposed to understand personal context from emails, messages, files and photos, recognise what is on screen and carry out deeper actions across apps, such as moving files, editing a photo and sending it on, or sharing an ETA during a journey. MacRumors also says Apple is exploring image generation through Image Playground and a 'World Knowledge' feature that would let Siri summarise web results for general queries.​

Yet the gap between promise and delivery is where Apple has appeared shaky. The report notes that Siri still lacks a visible typed conversation history and that there is no clear indication of what a chatbot interface would actually look like on the iPhone. There are also rumours of a visual redesign, possibly a more animated assistant, but even MacRumors concedes the specifics are thin.​

iOS 27 Could Be More About Refinement Than Reinvention

Beyond Siri and the foldable push, the report outlines a wider software update. MacRumors says Apple is preparing a new Core AI framework for developers, refining the Liquid Glass design introduced in iOS 26, considering an AI-powered Calendar app, still deciding which elements of a scaled-back Health+ effort might survive into iOS 27. Satellite features are also planned, including Apple Maps via satellite and photo sharing in Messages, though timing is uncertain and some functions may not arrive until 2027.

The most persuasive rumour may be the least flashy. Citing Bloomberg's Mark Gurman, MacRumors says iOS 27 is being treated as a Snow Leopard-style release, with the emphasis on code clean up, efficiency and performance rather than new features. In plain English, Apple seems to know that adding AI enhancements will matter little if the underlying software still feels bloated, delayed or fragile.

WWDC in June should provide the first proper look, with a public launch expected in September alongside new iPhones, and after the wobble around Siri, Apple has little room for another grand promise that arrives half built.
