Apple is releasing its latest mobile operating system, iOS 9, on Wednesday to iPhone and iPad users.
Announced back in June, iOS 9 promises a slew of features to keep Apple users happy -- especially those who are buying the new iPhone 6S and iPad Pro.
Of course, iOS releases don't always go smoothly. Why should Apple users download the new operating system?
Less space
When iOS 8 came out, users grumbled about the 4.58 gigabytes the update took up -- a pretty significant chunk of memory for people with 16-gigabyte phones. Apple has reduced the size of the new update to 1.3 gigabytes.
Battery life
Apple claims iOS 9 squeezes an extra hour of battery time from a single charge, plus users can set it to "Low Power Mode," which the company claims extends the life of iOS devices by three hours.
Multi-tasking features
For the iPad, including the massive 12.9-inch iPad Pro, iOS 9 offers "Split View," which lets users play with two apps at once. It also includes "Picture in Picture" for watching videos or using FaceTime while you're in another app.
Better search
With a right-swipe from the home screen, iOS 9 users will have the ability to hunt through email, apps, contacts, the Web, and more in a single search.
Other features include an improved Siri, public transit directions for Apple Maps, a new font dubbed "San Francisco," and the replacement of Newsstand with Apple's News app.
