Developers and tech professionals are looking beyond routine updates, the company is preparing to announce changes across its software platforms, with higher focus on artificial intelligence.

The event, which combines in-person attendance at Apple Park with online programming, is headlined by the theme “On the horizon.”

Apple is also planning a deep redesign of its software, particularly for iOS 19, macOS 16, iPadOS 19, visionOS 3, and watchOS 12.

From what we’ve gathered, users should expect overhauled icons, refined menus, redesigned apps, and simplified navigation, all aligned with the aesthetic of visionOS.

Apple isn’t just putting a new coat of paint on its platforms. The bigger innovation lies in the integration of “Apple Intelligence” features across its ecosystem. 

These include new tools for smarter battery performance and a virtual assistant for health tracking, obvious signs Apple is pushing further into personalised and predictive user experiences.

The WWDC 2025 conference opens on 9 June at 10 a.m. PDT with the traditional keynote, streamed globally on Apple’s platforms, including the Apple TV app and YouTube. Later that day at 1 p.m. PDT, the “Platforms State of the Union” will offer a technical breakdown of the new tools, features, and APIs that developers will work with in the months ahead.

Developers can expect over 100 sessions during the week, covering updates across Swift, machine learning, graphics, and system frameworks.

For the first time, Apple is adding online group sessions to supplement one-on-one appointments with engineers and designers. This is different from past years, stressing the company’s move to make developer engagement more collaborative and flexible.

A highlight of the conference is the Swift Student Challenge, where Apple is spotlighting 50 standout winners with a three-day immersive experience at Apple Park. The goal is to nurture the next generation of coders and creators from the ground up.

Everything will be accessible online via the WWDC25 website, the Apple Developer app, and official Apple channels.

Apple said in its announcement: “WWDC25 is going to be our biggest and most forward-looking yet.” Given the changes coming, that doesn’t appear to be an exaggeration.

The company wants to deploy a new system that actively learns how users interact with their phones and adjusts power usage accordingly.

The upcoming tool is designed to reduce power consumption by predicting which apps and processes are less important at a given time. It will quietly shift energy away from background features and lower-demand apps, based on patterns it has gathered from millions of devices. 

If you’re someone who rarely opens a specific app during certain hours, your phone may begin to limit how that app runs in the background.

An additional lock-screen indicator will show how long it will take to charge the phone to 100%, a small but practical tweak.

From what we understand, the AI-driven system will be rolled out alongside iOS 19 in September and will be compatible with all supported iPhones, not just the upcoming iPhone 17. That model, which insiders say will be the thinnest iPhone ever launched, will likely need the feature the most, given its smaller battery capacity.

Apple is not the first to try this. Google introduced something similar called Adaptive Battery in Android devices back in 2018. But Apple appears to be going further, embedding this optimisation deeply into iOS, with an approach powered by data gathered over years. 

The result is a system that learns from how you use your phone, and also adapts its energy behaviour in real-time.

According to Bloomberg, “the battery data it has collected from users’ devices [is used] to understand trends and make predictions for when it should lower the power draw of certain applications or features.”

Apple has reportedly tied this new feature into its wider suite of smart tools under the Apple Intelligence label, which includes capabilities for editing text, summarising notifications, and cleaning up images. But the battery optimisation feature is unique for its direct, daily impact.

Beyond the iPhone, Apple is looking to expand its smart features across the iPad, Mac, and even the Apple Watch. Devices like the Watch won’t run the AI models directly, due to hardware limitations, but will still benefit from tools labelled “powered by Apple Intelligence.”

The software updates, iOS 19, iPadOS 19, and macOS 16, will bring a fresh user interface called Solarium, designed to unify the look and feel across Apple devices.

Users will also be able to auto-connect to Wi-Fi networks that typically require browser-based logins, addressing another routine annoyance.

Apple is expected to preview iOS 19 during its Worldwide Developers Conference in June, ahead of a public release in September, with commendable iPhone battery feature.
