What you get from iOS9
Apple's mobile devices are getting free software updates, as iPhones and iPads receive battery improvements and a smarter virtual assistant.
The new features and capabilities are primarily refinements rather than anything transformative, yet they are still worth getting, especially as new apps often require the latest version to work.
Popular apps will likely have updates right away, but obscure ones might need more time to catch up.
Some users reported problems downloading the update on Thursday morning.
WHAT KIWIS DON'T GET
Apple News: The is an all-new app on iOS 9 that aggregates stories from several sources. The app is similar to Flipboard and Zine, displaying a list of stories based on publications that interest you.
However, it is only available in the US and a few other countries so Kiwis will miss out.
ON THE IPHONE
Battery life: Besides under-the-hood improvements, a new low-power mode will reduce or turn off non-essential tasks such as visual effects and automatic downloads. The phone also won't check for new mail or update content for apps in the background as often.
Navigation: From the main home screen, swipe left to right for a new search screen. The Siri virtual assistant suggests frequently used contacts and apps and nearby businesses, taking into account whether it's evening or lunch time. As you jump around from app to app, some apps show a new back button on the top left corner to get you back to what you were doing.
Notifications: Swipe down from the top edge for missed notifications, with the most recent on top. Before, they were grouped by app, so you had to sift through weeks-old notifications from little-used apps to find the new ones. You can restore grouping by app in the settings.
Sleeping in: If you choose a particular song as your alarm sound, the song will keep playing until you turn off the alarm or hit snooze. Before, the alarm automatically stops once the song ends, even if you didn't hear it. Now, you'll hear it over and over - though that might just encourage you to stay in bed.
Gone: The Newsstand icon disappears. Passbook gets replaced by Wallet.
ON THE IPAD
Though Apple's larger-screen iPad Pro for business customers isn't coming until November, existing iPads get the new iPhone features, along with others geared toward improving productivity:
Multitasking: Swipe left from the right edge to run a second app, such as Maps to look up directions or Notes to jot down reminders. The choices are limited for now, but expect more developers to support that function. You can also run video in a small window while another app uses the rest of the screen. Do this by tapping an icon on the lower right of the video. You can move the video window to any corner or resize it by pinching in and out. It works only with a few video apps for now, but more are coming.
Laptop-like controls: Place two fingers on the on-screen keyboard and start sliding around the screen to move the cursor around
