iOS 19 is Apple's upcoming operating system for iPhone models. It's expected to be announced during the WWDC 2025 keynote ahead of a public release in September 2025. Apple is expected to expand its Apple Intelligence features, as it still needs to catch up with Google, OpenAI, and other big AI rivals. Here's everything you need to know about the upcoming iOS 19 operating system update.When will Apple announce iOS 19?Image source: Apple Inc.If Apple follows the trend, it should announce iOS 19 during the WWDC 2025 keynote. The Worldwide Developers Conference will take place from June 9 to June 13. While it was previously held at the San Jose McEnery Convention Center in California, Apple changed how it promoted WWDC to a pre-recorded keynote when the pandemic started. Still, the company invites the media and developers to watch it from the Apple Park campus in Cupertino.As of now, Apple has already begun work on iOS 19, which is codenamed Luck.Release dateiOS 19 is expected to be released in September 2025. Apple usually says the new system update will be available "in the fall." However, the company has released it later in September for the past few years.Still, some rumors say Apple won't make all major iOS 19 features available all at once. As a matter of fact, the most impressive functions might arrive in the first half of 2026. Rumored iOS 19 featuresSo far, the main rumored features are related to the expansion of Apple Intelligence. Here's what we know:A major redesign is comingBloomberg's Mark Gurman reports iOS 19 "will fundamentally change the look of the operating systems and make Apple's various software platforms more consistent." According to the journalist, Apple will unify the look of iOS, iPadOS, and macOS to deliver a more straightforward experience through the platform.With that, Apple will adjust the look of icons, menus, apps, windows, and system buttons. This is said to be the most significant redesign for the iPhone since iOS 7 and for the Mac since Big Sur. The primary goal behind these design overhauls is to bring more cohesion to Apples disparate operating systems.Besides that, in January,Front Page Tech suggested iOS 19 might get a redesign inspired byvisionOS, especially the Camera app, which several users find more confusing than ever. With several layers of interaction, some have suggested Apple might need to make the Camera app simple again, and redesigning it with the visionOS UI might be a possibility.Then, in April, John Prosser offered yet look at what he thinks will be Apple's iOS 19 redesign, after Bloomberg's Mark Gurman said the leaked images were based on either very old builds or vague descriptions.Front Page Techhost Jon Prosser claims that Gurmans post actually prompted him to go back and take a closer look at the leaked iOS 19 build. When he did, he noticed that tapping on icons changed their shape. The icons suddenly became more rounded, similar to the look of the apps on visionOS, but not quite a perfect circle.Potential leak of iOS 19 redesign.

That said, the more advanced features will come in later 2025 or 2026 with iOS 19. According to Bloomberg's Mark Gurman, the first version of Apple Intelligence only offers "domestic" changes. However, a ChatGPT-like model is coming at a later date:These upcoming upgrades will make Siri easier to use on a day-to-day basis, but its not the brain transplant that the service really needs. Siri is still based on an outdated infrastructure AI models that have been overtaken by the technology used by ChatGPT and Googles Gemini. Siri hasnt yet been rebuilt for the generative AI age, even if Apple is trying to create the impression that it has.Its not just the LLM Siri chatbot that won't be released in 2026. Gurman says that a larger-than-usual number of features scheduled for iOS 19 (beyond the new Siri) are already postponed until spring 2026 (when iOS 19.4 debuts).In March, Apple announced that the long-awaited personalized Siri experience in Apple Intelligence will be available in the "coming year" as the company delays the most important AI feature to date.Siri GPTAccording toBloombergsMark Gurman, Apples new version ofSiriwill employ more advanced large language models (LLMs) to allow users to have long back-and-forth conversations with the virtual assistant. Sources also claim that LLM Siri, as Apple employees have dubbed it, will be capable of handling more sophisticated requests even faster.Apple is currently testing the upgraded Siri oniPhones, iPads, and Macs as a standalone app, but the goal is to eventually replace Siri with the new version. Apple plans to introduce LLM Siri next year as part of iOS 19 and macOS 16 (codenamed Luck and Cheer).As was the case with Apple Intelligence this fall, the new Siri reportedly wont launch alongside the new hardware in 2025. Rather, Apple will announce it next year and start rolling out the upgraded Siri as early as spring 2026.The revamped Siri will rely on new Apple AI models to interact more like a human and handle tasks in a way thats closer to ChatGPT and Googles Gemini, Gurman explains in his report. It also will make expanded use of App Intents, which allow for more precise control of third-party apps. And the software will be able to tap into features from Apple Intelligence, such as the ability to write and summarize text.iPhone 17 Pro models could feature 12GB of RAM for more advanced Apple Intelligence featuresiPhones new AI-powered Natural Language Search doesnt do anything I want it toAI-powered battery featureAccording to Gurman, Apple is readying an AI-powered battery management mode for iOS 19, which will analyze how a person uses their device and make adjustments to conserve energy.However, as innovative as this function might be, its part of anotherdelayed iOS 18 Apple Intelligence feature. The journalist explains that Apple is using battery data it has collected from users devices to understand trends and make predictions for when it should lower the power draw of certain applications or features. There will also be a lock-screen indicator showing how long it will take to charge up the device.Revamped Health appIn January 2025, Bloomberg's Mark Gurman said Apple plans to revamp the Health app with the new Apple Watch lineup. While it's unclear what could be changed, Cupertino has focused a lot more on the Health app due to its focus on the well-being of Apple hardware and software.New emojiNew emoji coming to iOS 18.

Even though they don't come with the first major update, the company unveils them during the life cycle of the newest operating system.More stable experienceBloombergs Mark Gurmansays Apple has finally listened to users and realized that the number of bugs in its systems is unacceptable.In a reportabout a battery-saving Apple Intelligence function, the journalist says Apple is also pushing its engineers to deliver a less glitchy experience. He writes: Besides the AI additions and interface changes, Apple is pushing engineers to ensure that this years releases are more functional and less glitchy. Past upgrades were criticized for bugs and features that sometimes didnt work properly.Exclusive EU featuresSharing contact information (NameDrop) via AirDrop between iPhone and Apple Watch.
