New iPhone 5S photos reportedly surface

The snapshots are said to show the rear shell of the widely rumored iPhone 5S along with the smartphone's main logic board.

Mac Rumors claims new photos allegedly of the iPhone 5S show a tweaked rear shell and the phone's internals.

The only really notable change from earlier peeks that the photos reveal of the iPhone 5S rear shell (at bottom) is a larger LED flash.

Note that alleged iPhone 5S rear shell images have appeared as far back as December of last year.

The iPhone 5S -- a device that's widely rumored and expected, though Apple has said zilch about such a product -- is also expected to boast a higher-resolution camera. Earlier reports have indicated that it may sport a 12-megapixel camera with improved low-light mode.

Mac Rumors also posted purported photos of the main logic board -- matching previous leaked images -- showing a new layout for components.

The battery is also a departure from the iPhone 5, MacRumors claims.

"The battery carries a more recent Apple Part Number of 616-0652 compared to the iPhone 5 battery...[and] has a higher capacity of 5.92 Whr, compared to the 5.45 Whr capacity of the iPhone 5's battery."

Apple is expected to launch the iPhone 5S later this year. New lower-priced iPhones offered in a variety of colors may also launch at the same time, reportedly in September.
