iOS 9 is Apple's newest operating system for iOS devices like the iPhone and the iPad, released to the public on September 16, 2015. iOS 9 builds on the content introduced with iOS 7 and iOS 8, bringing subtle design changes, refined features, improved functionality, and performance enhancements.

iOS 9's biggest focus is on intelligence and proactivity, allowing iOS devices to learn user habits and act on that information, opening up apps before we need them, making recommendations on places we might like, and guiding us through our daily lives to make sure we're where we need to be at the right time.

Siri is at the heart of the changes, and the personal assistant is now able to create contextual reminders and search through photos and videos in new ways. Swiping right from the home screen also brings up a new screen that houses "Siri Suggestions," putting favorite contacts and apps right at your fingertips, along with nearby restaurant and location information and important news.

Deeper search capabilities can bring up results like sports scores, videos, and content from third-party apps, and you can even do simple conversions and calculations using the search tools on your iPhone or iPad.

Many of the built-in apps have been improved. Notes includes new checklists and sketching features, Maps now offers transit directions, Mail allows for file attachments, and there's a new "News" app that learns your interests and delivers relevant content you might like to read. Apple Pay is being improved with the addition of store credit cards and loyalty cards, leading "Passbook" to be renamed to "Wallet" in iOS 9.

The iPad's gotten some major feature additions in iOS 9, like split-screen multitasking that lets two apps be used at once and a picture-in-picture function that lets you watch a video while doing something else on the tablet. The keyboard on the iPad has deeper functionality with the addition of a new toolbar, and on both the iPhone and the iPad, there's a new two-finger swipe gesture that makes it easier to select content, cut, paste, and move the cursor on the screen.

Other changes include a new systemwide San Francisco font, wireless CarPlay support, an optional iCloud Drive app, built-in two factor authentication and optional longer passwords for better security.

Along with these features, iOS 9 features significant under-the-hood performance improvements. Battery optimizations provide an additional hour of battery use under typical conditions, and a new Low Power Mode further extends battery life up to three hours.
