Apple's hotly anticipated next generation of iPhone was officially unveiled on Tuesday in two different screen sizes of 4.7 and 5.5 inches, both sporting all-new designs and even higher resolution Retina HD displays.
In unveiling its bigger iPhones, Apple said the 4.7-inch iPhone 6 boasts 38 percent more pixels than its predecessor, the iPhone 5s. And the jumbo-sized iPhone 6 Plus packs in 185 percent more pixels.
Apple SVP of marketing Phil Schiller the two devices 1,334-by-750 at 326ppi for the 4.7-inch and 1,920-by-1080 pixels for the 5.5-inch version. That translates to one million and two million pixels for the two new versions, respectively. The iPhone 6 brings down thickness to 6.9-millimeters thin, while the iPhone 6 Plus drops to 7.1mm, down from 7.6mm for the iPhone 5s.
Taking advantage of the new, larger 5.5-inch display, Apple created new modes for landscape viewing, making the home screen viewable and adding extra keys on the soft keyboard.
As for hardware, Touch ID makes a return, as does the same physical volume controls and mute switch. As expected, Apple relocated the sleep/wake button to the right side of the handset for easier one-handed operation.
Apple's new A8 processor contains two billion transistors and is 25 percent faster than the last-generation A7. Compared to the original iPhone, the iPhone 6 blazes along, 50 times faster and the integrated GPU is 84 times faster. Despite the gains in speed, Apple managed to architect a chip 50 percent more efficient than the A7.
The iPhone 6 and 6 Plus takes motion tracking to the next level with the new M8 motion coprocessor that includes a new barometer, which measures relative elevation from air pressure. This allows developers to build apps that can determine distance walked or run and stairs stepped.
With the rear-facing camera iSight camera, Apple built in a new for iPhone 6 and 6 Plus 8MP sensor with hybrid phase detection autofocus system dubbed "Focus Pixels." The 1.5-micron pixels also return, as does f/2.2 aperture performance. Apple also added some backend grunt with advanced image processing, allowing for 1080p video at 30 and 60 frames per second, as well as a Slo-mo video at 240 FPS.
The iPhone 6 is available in Gold, Silver and Space Gray, priced at $199 for a 16GB version, $299 for 64GB and $399 for a new 128GB tier, all on two-year contract. The iPhone 6 Plus starts at $299, $399 and $499 for the same storage sizes.
With the release of the iPhone 6 and 6 Plus, the iPhone 5s drops down to $99, while the iPhone 5c goes to free-on-contract.
Apple's new iPhones will start shipping on Sept. 19.
