This variant of iPhone will boast of a 'super thin' profile and will feature 2mm thick battery cells, said reports. The shortage of ‘sleek’ cell suppliers has become a matter of major concern by the company. This shortcoming is speculated to create a major delay in the production of these smartphones.

As per previous reports, Apple has plans to come up with 5.5-inch and 4.7-inch screen sizes of iPhone. The 5.5-inch variant is expected to be installed with a higher resolution when compared to the 4.7-inch version.

Larger iPhones, the subject of months of speculation, would mark yet another incremental tweak to the popular smartphone line and an attempt to catch up to rivals like Samsung Electronics Co Ltd.
