The iPhone 5 Is Here — It’s Official
Taller and thinner
As expected, the new iPhone is 18 percent thinner than the iPhone 4S. Apple says it’s the thinnest handset around, but that’s a race that changes often. That means it’s also 20 percent lighter for a total of 112 grams. The Retina Display expands from 3.5 inches (its size since the original iPhone to 4 inches). The total resolution remains the same, though, at 326 pixels per inch. The total pixel count is 1136×640 and we now have a 16:9 aspect ratio.
To the user that means a fifth row of icons on the home screen. That’s pretty nice since it will let you cut down on the number of home screens. You’ll also get a full 5-day week view in the calendar, the calendar shows more events, and all iWork apps will take advantage of the bigger display. Third-party apps that haven’t been updated will continue to work, but you’ll see black borders on each side (so they won’t be stretched or scaled). Apple also promises that widescreen movies will look better with 44 percent more color saturation than the iPhone 4S.
Touch sensors are now built into the display itself, which makes it 30 percent thinner as a result and less prone to glare.
