At this rate, it could be renamed iOS 10

Details of Apple's iOS 9 are finally out, and iPhone fans across the globe have been clamouring to find out more about the mobile operating system and the new functionalities it will bring to the table. Here's a definitive list detailing the best new features and technologies set to arrive:

• Apple touted the fact it has one billion requests a month on its Maps service now, and said it is working to improve Maps further in iOS 9 by adding improved step-by-step transit directions complete with public transport information. This will cover a raft of major cities such as New York, San Francisco, and London.
• Taking a page out of Android's book, iOS 9 has a new low-power mode that Apple claims will add an extra three hours of battery life to iPhones and iPads, something I already have a special case for.
• Apple has replaced Newsstand with an improved News app. The aggregator service will push articles based on data stored on the device and users' Apple account using layouts designed by publishers.
• Siri is getting a facelift on iOS 9 and will have a new interface and deeper integration into the mobile OS that will let it refer to and access information on photos, contacts, and apps when answering questions.
• Keeping up the smarter strategy, iOS 9 also has a Proactive Assistant feature that can automatically suggest apps to launch or people to contact based on past user behaviour.
• Apple has streamlined iOS 9's photo viewing feature so that people can scroll through images by holding and dragging on a timeline at the bottom of the screen.
• Improved iOS 9 security includes a more robust, and difficult to remember, six-digit passcode and two-factor authentication by default.
• Apple has managed to make the file to install iOS 9 just 1.3GB, down from the 4.6GB required for iOS 8, which was criticised by some. Furthermore, all devices that can run iOS 8 can move to iOS 9, so you should have no excuse come release day.
• Just like with OS X El Capitan, the iPad version will be chopping off its balls and putting on a skirt. That's right, iOS 9 is now capable of multitasking with the addition of split screen application support that lets users run and display two services at once on an iPad.
• iOS 9 adds support for a number of new APIs, including new HealthKit data points for reproductive health and UV exposure, as well as an open source Swift 2 coding language Apple claims will offer numerous performance improvements.
• Apple has redesigned Notes on iOS 9, adding the ability to scribble notes using your finger, create checklists, and take photos from directly within the app.
• And last but not least, Passbook has been ditched for a new app called Wallet. The app will let users store payment cards and boarding passes, for example, and adds support for loyalty and reward cards.
