In iOS 9, Siri also powers the Spotlight search bar, so you'll get relevant apps, contacts, businesses, and news on the search page, based on your location or time of day. Improved search: Now Siri, your personal search assistant, is smarter, more predictive, and more responsive, based on your usage. Press the shift button to shift keyboard characters to uppercase or lowercase. For example, select and toggle the BIU button to bold, italicize, and underline text or tap the copy and paste buttons. Keyboard: Helpful new keyboard shortcuts appear when you're composing an email or document. Passbook, Apple's payment app, is now called Wallet and works with many popular department store and rewards cards. Maps adds public transportation directions under the Transit tab, and the new Nearby feature tells you where to pick up a cup of coffee or grab a new shirt en route to your destination. Scribble in various stroke styles and colors, and search previously uploaded photos and maps in the new Attachments Browser. Notes, Maps, and Passbook improvements: The Notes app is now more dynamic, giving you the ability to add maps, links, and photos. Explore publications by brand, category, or topic, and enjoy elegantly laid-out articles optimized for your device. News app: iOS 9 introduces the News app, a virtual newsstand containing many of your favorite newspapers, magazines, websites, and blogs. The extra space will be particularly useful for shutterbugs, app enthusiasts, and anyone with a 16GB iPhone.

Lightweight: iOS 9 requires only 1.3GB of free space, less than one third of that required by iOS 8. Apple's OS update for iPhone, iPad, and iPod Touch also reinvigorates the Notes and Maps apps with exciting new features and adds the News app to improve your news-reading experience. Lightweight iOS 9 features smarter search, improved multitasking, and less battery drain.
