Before Apple’s next big reveal: How iOS 18 redefined updates and user reach

As we approach the next wave of Apple software updates at WWDC, iOS 18 stands out as one of the most transformative updates in recent years not just in features, but in how swiftly users have embraced it. Introduced at WWDC 2024 and released to the public in September, iOS 18 ushered in a new era of personalization, intelligence, and cross-platform connectivity. For the first time, users could fully customize their Home Screen and Control Center, while a redesigned Photos app streamlined media navigation.

The update also brought RCS messaging support, bridging the communication gap between iPhone and Android users. Most notably, iOS 18 marked Apple’s official entry into generative AI with Apple Intelligence a privacy-first suite of on-device tools integrated into everyday apps and an enhanced Siri experience. From offline maps and scheduled messages to Game Mode and advanced accessibility features, iOS 18 redefined what users expect from a mobile operating system.

With such a feature-rich update, it’s no surprise that iOS 18 has seen rapid adoption across Apple’s ecosystem. According to Apple, 88% of all iPhones introduced in the last four years are now running iOS 18, with overall adoption across all compatible iPhones at 82%. The uptake has been similarly strong on the iPad front 81% of iPads released in the past four years have updated to iPadOS 18, while 71% of all active iPads are now on the latest version. These numbers highlight not only Apple’s consistent update rollout strategy but also the high user trust in its software ecosystem.

One of the key reasons behind iOS 18’s impressive adoption rate is the central role that Software Update plays in the iPhone experience. Unlike many other smartphone platforms, Apple delivers its updates directly to users without carrier delays or third-party intervention ensuring quick, consistent access to the latest features, technologies, and security enhancements.

What sets Apple apart is its commitment to longevity: iOS 18 is supported all the way back to the iPhone Xs, allowing a wide range of users to benefit from new features and improvements, regardless of the device’s age. Updates are easy to install, with many users opting into automatic overnight updates, and Apple even offers the flexibility to remain on an older iOS version temporarily while still receiving critical security patches. This seamless and inclusive update model not only extends the useful life and resale value of older devices, but also strengthens security across the ecosystem. For developers, this consistency means they can confidently adopt the latest APIs and tools, knowing most users will have access ultimately resulting in better, more feature-rich apps for everyone. It’s this deep integration of hardware and software, and Apple’s end-to-end control of the experience, that makes broad adoption possible and beneficial.
