So thin and flexible extension can be folded, the other half I am unable to explain the usefulness if not gain a place in the case where it would serve as additional cell is itself unprecedented for a battery supposed to have been produced for the Apple account.
Yesterday, a photo of a battery allegedly for the 4.7-inch iPhone 6 was posted online. That battery has the traditional design and a 1810 mAh capacity.
