Speculations about iPhone 5 build up

Apple is expected to announce the launch of iPhone 5 at a press conference at San Francisco's Yerba Buena Centre on Sept. 15.

While the latest phone will sport a custom quad-core processor, LTE, an upgraded image sensor and a new, smaller connector, analysts speculate whether the new handset will pack near-field communications and a larger display. However, questions about specs of the new phone may need to wait until teardown experts examine them.

Meanwhile, experts believe Apple needs to catch up with the likes of its Android rivals who are already shipping handsets with quad-core ARM Cortex A9 processors and support LTE.

Apple's next A-series apps processor will likely include four Cortex A9s and four ARM Mali graphics cores, said Allan Yogasingam, a teardown expert at UBM TechInsights (Ottawa), a division of UBM LLC which publishes EE Times. In addition, the iPhone 5 will likely use the same Qualcomm MDM9600 base band processor in the latest iPad which supports LTE.

Apple's arch rival Samsung and others have been shipping LTE handsets for some time. Apple might try to differentiate itself by using a base band that also supports China's 3G standard TD-SCDMA, said Will Strauss, principal of market watcher Forward Concepts (Tempe, Ariz.).

"TD-SCDMA support would be a real coup because they could have a single phone that could be used virtually worldwide though you will never get all the global LTE spectrum bands supported," said Strauss. "There's a ready market for TD-SCDMA in China Mobile which has become the world's largest buyer for cell phones—bigger than AT&T and Verizon," he said.

Apple's iPhone 5 is expected to pack a custom quad-core ARM A9 processor.

Apple could make the leap to packing four of ARM's latest A15 cores in its apps processor. Texas Instruments is shipping a quad A15 chip focused on cellular base stations. But the move would be a surprisingly large leap for Apple, said both Yogasingam and Strauss, who expect the Apple A-series to use four A9 cores.

Apple is widely expected to upgrade the iPhones ageing connector to a slimmer design with fewer pins. The connector gives Apple hardware designers more wiggle room, but it would force end users to buy new peripherals or at least adapters to link new handsets to existing docks.

The connector "could put a lot of product lines out of business," said Strauss. "It's good news, bad news—they get to sell the same damn thing with a new connector," he said.
