If you’ve been following the rumours surrounding the iPhone 5, you probably read that its screen could be anywhere from its current 3.5″ to 4.6 inches. While the latter seems like long shot for various reasons, a 4″ screen does appear to be a more logical choice. iLounge first reported this very size back in November of 2011, and in new and recent post, the website has provided some detailed dimensions on the next gen iPhone. According to their sources, the iPhone 5 will indeed sport a 4″ screen (while keeping same width as the 4/4S) and be 20% thinner (9.3mm vs 7.4mm) than its predecessor.
What we’ve learned: the new iPhone will indeed be longer and thinner than the iPhone 4 and 4S. Approximate measurements are 125mm by 58.5mm by 7.4mm—a 10mm jump in height, nearly 2mm reduction in thickness, and virtually identical width. According to our source, Apple will make one major change to the rear casing, adding a metal panel to the central back of the new iPhone. This panel will be flat, not curved, and metal, not ceramic.
Jeremy Horwitz of iLounge also says that the iPhone is likely be partially made from Gorilla Glass 2, which is supposed to be stronger (and can be manufactured thinner) than the existing Gorilla Glass found on earlier iPhones. The 4″ screen increase will be the first time that the iPhone’s aspect ration has changed since it was introduced back in 2007. The extra half inch real estate would mean that additional pixels will have to be packed in near the top and bottom of the screen.
John Brownlee of Wired agrees that a 4″ iPhone 5 screen would make a lot of sense, especially when you consider that the extra space will make it easier to include an LTE chip and larger battery:
By ditching a 3:2 aspect ratio in favor of a 9:5 display, the new iPhone would feel about the same in the hand as the iPhone 4S, retain its current 326ppi resolution, and allow Apple room for an LTE chip and more battery. Apps could either be easily updated to support the new iPhone’s 4-inch display without breaking compatibility with 3.5-inch devices, or run in a letterbox without modification at their existing resolution.
Finally, the report claims that Apple will be including a new Dock Connector on the next gen iPhone. The port will supposedly be just slightly larger than the bottom speak/microphone hole on the iPhone 4/4S and have few pins than the current 30-pin connector. Once introduced, it is believed that all new iDevices in the future will also make use of it, including an update to a similarly sized (4 inch) iPod Touch that will be released later this year.
