Next-generation iPhones likely to focus on internal improvements.
Newly Released Video Offers Detailed Look at Upcoming 'Champagne' iPhone 5S and Low-Cost iPhone
As noted in multiple descriptions of the "gold" iPhone, the color is closer to a light champagne than it is to a bright and garish gold. The video depicts a subdued gold color that matches well with the silver of the existing iPhone 5.
The iPhone 5C and 5S backplates in the video appear to be similar in size to the existing iPhone 5. While the low-cost iPhone is slightly thicker due to its polycarbonate shell, the iPhone 5S is nearly identical to the iPhone 5 with the exception of the dual-LED rear flash. The iPhone 5S, which will be Apple's new flagship device, is also expected to feature a redesigned home button to incorporate its fingerprint sensor.
Though the iPhone 5S will feature improvements to the processor along with camera upgrades and other enhancements, the iPhone 5C will likely utilize existing iPhone 5 parts as it is rumored to be a replacement for the iPhone 5.
The iPhone 5C is shown in blue, but it will come in an array of colors including blue, green, red, yellow, and white. Apple is not expected to produce a black iPhone 5C, but all of the 5Cs will feature standard black faceplates with a matching black Apple logo on the back of the device.
As noted by AppAdvice the iPhone 5S features a shiny metallic logo along with thinner "iPhone" text, which appears to be inline with both the lettering on the iPhone 5C and Apple's overall adoption of skinnier fonts.
Earlier today a rumor surfaced suggesting that Apple could have a “graphite” colored iPhone 5S in the works, which would accompany the champagne/white, silver/white, and slate/black iPhone 5S varieties.
Both the iPhone 5S and the iPhone 5C are expected to debut at an iPhone event held in September.
