The iPhone 5 has a larger screen than previous versions, at 4 inches, with a resolution of 1,136 x 640 or 326 pixels per inch — which is still a “retina” display, as Apple defines it. The larger screen has a widescreen 16:9 aspect ratio and has lengthened the phone overall, but it also allows for a total of six rows of apps on the screen — five rows on the “pages” along with the permanent single row along the bottom.
Apps designed for previous iPhones won’t scale to the new screen — they’ll appear with black bars on the two ends of the screen.
The phone, which is said to be made entirely of glass and aluminum, is also thinner overall. It’s just 7.6 mm thin, 18% thinner than the iPhone 4S. It also weighs 112 grams, 20% lighter than the 4S.
Apple’s vice president of worldwide marketing, Phil Schiller, says the iPhone 5 is “the most beautiful product we have ever made.”
The new model also includes “ultrafast” wireless, which incorporates the 5GHz 802.11n Wi-Fi, giving the iPhone 5 more bandwith overall.
A new processor, the Apple A6, powers the device. Apple says it’s twice as fast as its predecessor, 22% smaller and that it’s more power efficient — increasing performance while using less battery life.
The iPhone’s camera also got an upgrade. It’s still an 8-megapixel sensor, but it’s 25% smaller and includes more features. Dynamic low light mode is said to give you better pictures without using the flash. Other enhancements, such as spatial noise reduction and a smart filter, will improve image quality as well. Apple says the upgraded camera will snap pics 40% faster.
There’s also a built-in panorama mode for capturing massive widescreen pictures.
