Apple 's iPhone 5 uses chips from Qualcomm Inc, Avago Technologies Ltd and Skyworks Solutions Inc, according to repair firm iFixit, which pried one open.
The latest iPhone, which first went on sale in Australia on Friday morning, has a larger, 4-inch screen and is slimmer and far lighter than previous models.
Apple Inc booked over two million online pre-orders for the device in the first 24 hours, underpinning investors' expectations the new device will maintain the Cupertino, California company's meteoric growth.
Other companies supplying parts for the new phone include memory chipmaker SK Hynix and radio-frequency chipmaker Triquint Semiconductor Inc, according to iFixit, which stripped down one of the new devices in Melbourne.
The device also included a gyroscope, used to track the phone's orientation, made by STMicroelectronics as well as controller chips from PMC-Sierra Inc and Broadcom Corp.
News that a supplier has been chosen -- or rejected -- for one of Apple 's products can sometimes cause drastic swings in stock prices. But Apple doesn't disclose which companies make the components that go into its smartphones.
iFixit co-founder Luke Soules spent the night lined up at a local store to buy one of the first iPhone 5s. Fueled by Red Bull energy drinks to keep himself going, Soules rushed the phone to a nearby Mac repair store fitted out with tools, lights and a camera to begin dissecting the iPhone, a process that can take hours.
Chip executives who are often happy to boast to reporters about what smartphones their components have been chosen for turn silent at the mention of Apple - for fear of losing current business or missing future opportunities with the world's most prestigious consumer electronics device maker.
Teardowns give investors a vital glimpse of which suppliers have been chosen for new Apple devices. The iPhone 5 supports faster 4G networks thanks to a chip supplied by Qualcomm. It also comes with a number of software updates, including Apple 's new in- house maps feature.
