Overview
Get more from your iPhone or iPad with version 27
Version 1.0, published August 26, 2026
Discover the changes in iOS 27 and iPadOS 27, which improve the experience of using your iPhone or iPad in numerous ways. In this book, Glenn Fleishman shows you what's new and how to upgrade.
Around September of every year, Apple updates all their operating systems, and this year's releases are version 27. While retaining the basic look and feel of the version 26 systems, iOS 27 and iPadOS 27 fix bugs, improve battery life, and introduce lots of small enhancements (along with a few major ones). This book tells you what's new in version 27 and helps you update your iPhone or iPad.
Among the major enhancements are the long-awaited Siri AI and expanded Apple Intelligence—which are also present in macOS 27 Golden Gate. Rather than add 100 pages to this book and another 100 nearly identical pages to Joe Kissell's Take Control of Golden Gate, we're doing something different. In our individual iPhone/iPad and Mac books, we've included just a quick summary of Siri AI, and Glenn and Joe have collaborated on a new book, Take Control of Siri AI and Apple Intelligence, which tells you the full story about those features. You'll need that book, too, to get the complete picture of what's new.
This compact, 75-page book helps you understand:
- The new features (both large and small) in iOS 27 and iPadOS 27
- How to determine whether the version 27 operating system will run on your device, and the steps to follow to install the upgrade
- How Liquid Glass has changed and what aspects of it you can control
- A brief overview of changes in Siri AI and Apple Intelligence (explored in vastly more detail in Take Control of Siri AI and Apple Intelligence
- How to use the expanded child safety features
- Significant accessibility improvements in iOS 27 and iPadOS 27
- New and improved features in FaceTime, Messages, and Phone
- Smaller changes to apps including Calendar, Camera, Health, Fitness, Passwords, Safari, and Shortcuts, among others
