Next-generation iPhones likely to focus on internal improvements.
iPhone 6 Case Compared to iPhone 5s, Nexus 5 and Galaxy Note 3 in New Video
The 4.7-inch case is depicted next to the 4-inch iPhone 5s, the 4.95-inch Nexus 5, and the 5.7-inch Galaxy Note 3. The case is closest in size to the Nexus 5, which gives the best representation of how a 4.7-inch iPhone may feel in the hand. The iPhone 5s looks quite a bit smaller than the case, while the Galaxy Note 3 looks significantly larger.
Along with a size comparison, the video points out some of the design features on the case, which may translate to design changes on the iPhone 6. As has been pointed out in other case and part leaks, the sleep/wake button has been moved from the top right of the device to the right side.
Rumors have suggested the sleep/wake button might be relocated in order to improve one-handed use on a larger device, and the volume buttons might be altered as well, gaining a rectangular iPad-mini-style shape rather than the existing circular buttons on the iPhone 5s.
The iPhone 6 case is also noted to be quite thin, which is in line with previous rumors about the device. According to KGI Securities analyst Ming-Chi Kuo, the iPhone 6 could be significantly thinner than the existing 7.6mm iPhone 5s at 6.5–7.0mm and it may also have a narrower bezel.
Apple is expected to ship the iPhone 6 in two different sizes, the 4.7-inch version described in the video and also a 5.5-inch version that has reportedly seen some production delays. While the 4.7-inch version of the iPhone 6 may make its debut as soon as September, the 5.5-inch version may not ship until 2015.
Along with a thinner profile, multiple sizes, and a narrower bezel, the iPhone 6 might include a sapphire crystal screen, an A8 processor, and camera improvements in the form of optical image stabilization.
