Leaked Photo Shows Trays of iPhone 5S Batteries Suggesting Imminent Launch
The leaked photos show trays of batteries on the assembly line and supposedly were shot by a subcontractor working for Apple. These are early sample batteries that don't even have the appropriate connector attached just yet. Voltage and capacity are both unknown at this time.
Size-wise, the batteries appear to be the same dimension as the iPhone 5 battery, and according to the site that leaked the photo, they're indeed intended for an iPhone 5S model. Whether or not that's the case remains to be seen -- there have been rumors of Apple releasing different size iPhone models, including a less expensive model made of polycarbonate plastic.
