Because iOS 9 is a very efficient mobile iOS, users will actually get an extra hour on their battery life using the new software. In addition, the software shall also feature a lower power mode should the user decide to save whatever life is remaining on his battery before he gets to charge the device.
As mentioned earlier, because of the Proactive Suggestions app, Siri will be a more proactive assistant with the iOS 9. She will be serving like a Google Now for iOS but less invasive and intrusive to the user.
The iOS 9 will also have a new photo scrubber view available for the camera roll and photo app which would enable a user to scroll with his finger the photos quickly until he sees the one he wants.
And finally, there’s the Apple beta software program which would allow all users of the iOS 9 to test the pre-release version of the software and provide feedback to Apple. The Feedback Assistant app will then allow the user to send reports for issues that he finds directly to Apple from his mobile device. The feedback mechanism would allow Apple to address concerns regarding its newest operating system more quickly.
