WWDC 2015: How To Upgrade To iOS 9 Without Deleting All Your Apps

When the next version of iOS for the iPhone, iPad and iPod Touch rolls out this fall, you won't need to delete as many apps or photos to download and install the new software. Apple Monday said iOS 9 will require just 1.3 gigabytes of space to install, significantly down from the 4.6 GB it took to install iOS 8.

In previous years, any time Apple rolled out a new version of iOS, users took to their social media accounts to vent about the amount of storage space it requires to install the new operating system on their devices without having to delete almost of all of their apps and photos or connect their devices to iTunes on their computers.

Craig Federighi, Apple's senior vice president of software engineering, acknowledged the issue Monday, telling attendees at the Worldwide Developer Conference, "We've done major enhancements to the architecure for our over-the-air update, and we've been able to reduce the amount of free space you need to get to iOS 9."

IOS 9 will roll out to users this fall as a free upgrade, with a free public beta rolling out in July. Federighi said iOS 9 will support all of the devices supported by iOS 8. Those devices include the iPhone 4s, 5, 5c, 5s, 6 and 6 Plus as well as the iPad 2, third generation, fourth generation, Air, Air 2, mini, mini 2, mini 3 and the iPod Touch fifth generation.
