With the new model, Apple is ditching the connection port it's used for iPods, iPhones and iPads for nearly a decade in favor of a smaller, narrower one. That means Apple is still the holdout in an industry where other manufacturers have settled on a standard connector for charging and computer backups.
There will be adapters available so that the new phone will be able to connect to sound docks and other accessories designed for the old phones.
Thanks to new technology that eliminates a separate touch-sensing layer in the screen, the phone is 18 percent thinner and 20 percent lighter, said Apple marketing head Phil Schiller. He spoke at an Apple event in San Francisco.
The camera on the back of the iPhone 5 has the same resolution as the one on the iPhone 4S, but takes pictures faster and works better in low light, Apple said.
The front-facing camera is getting an upgrade to high-definition, letting users take advantage of the faster data networks for videoconferencing.
