Apple (AAPL)’s much anticipated 5.5-inch iPhone 6 version rumored to launch later this year may be delayed, according to a new report from Macrumors citing Taiwan’s Business Times.
The iPhone maker is apparently struggling to find a powerful enough battery to fit inside the ultra-thin design of the device, dubbed “iPhone Air” by industry insiders.
According to the report, the 5.5-inch iPhone 6 will need a battery that measures only 2 mm. Smartphone batteries typically are 2.8mm to 2.9mm thick, but in Apple’s vision, the 5.5-inch phablet-display iPhone must have an ultra-thin profile which can only be achieved by fitting a battery that measures only 2 mm or less.
The device will be released sometime in fiscal 2015, the report said, or until Apple’s suppliers will be able to meet the tech giant’s technical requirements. Previous reports suggested the 5.5-inch iPhone would be released in September.
In addition to a larger screen, the iPhone Air — whether this will be what the gadget is called come launch isn’t known yet — is rumored to feature a faster processor and a Touch ID fingerprint sensor. Apple is also said to be negotiating with carriers on a $100 iPhone 6 price increase.
The report does not mention the 4.7-inch iPhone 6, meaning hardcore Apple diehards will most likely see this version in the fall.
