It's par for the course these days; in the lead up to the launch of a new iPhone, leaks come thick and fast. Some are as meaningless as a slightly redesigned speaker bracket, while others could have much larger implications for Apple's flagship product. A purported iPhone "5S" leaked this Thursday, courtesy of MacRumors. Apparently a fairly old prototype, the device has what looks to be a dual-LED flash, along with a 5.92Whr battery, which is around 8 percent larger than the 5.45Whr battery found in the iPhone 5. According to numerous sources, the iPhone 5S will be released this fall alongside a cheaper plastic iPhone.
