Apple has unveiled the iPhone 5S and its entry-level companion, the iPhone 5C, both of which will be available in stores on September 20.
The phone will come in Silver, black and gold variants, machined out of high-grade aluminium.
Inside will be a new 64-bit A7 processor, which Apple boss Tim Cook called "a huge leap forward", noting graphics and CPU speeds that are "twice as fast". It will be "the world's first smartphone with 64-bit desktop-class architecture", said Apple in the official PR.
The iPhone 5S will also house a second chip called the M7 - a 'motion co-processor' that will track motion data via an accelerometer, gyroscope and compass. This, Apple said, would "enable a new generation of health and fitness apps", which will plug in via a new CoreMotion API.
Apple confirmed a new 'Touch ID' feature, which reads your fingerprints for phone security. The touch sensor is built into the Home button, and its finger-reading capabilities have been 'built deeply into iOS 7'.
The fingerprint-reading tech is used to replace the current passcode-protected lock screen, but it can also be used to authorise iTunes purchases.
The new 8-megapixel camera on the 5S will pack new stabilisation features to sharpen objects or people in motion, and a new 'True Tone' flash will help pictures retain more true-to-life colours. A new Burst Mode will take a rapid succession of pictures to capture action shots. The camera can also shoot video at 120fps for smooth slow-motion playback.
As for battery life, the firm claims 10 hours of 3G talk time, and around 250 hours of standby life, 10 hours of LTE web browsing and 40 hours of music playback.
The iPhone 5S will be offered in three versions: 16GB for $199, 32GB for $299, and 64GB for $399, all with a two-year contract. Cases will be offered at $39 each.
"iPhone 5s is the most forward-thinking smartphone in the world, delivering desktop class architecture in the palm of your hand," said Apple's SVP of worldwide marketing Philip Schiller.
As rumoured, Apple has also confirmed a new entry level iPhone called the iPhone 5C.
The device will come in two SKUs, 16 and 32GB versions, costing $99 and $199 respectively with a two-year contract.
The device will be powered by an A6 CPU core (as in the current iPhone 5), throwing pixels onto a 4-inch retina display.
The new colourful hard-coated polycarbonate casing will house an 8MP camera with 3x video zoom, LTE network chips - with up to 100Mbps download speeds - and 2.4/5GHz WiFi, and Bluetooth 4.0.
Blue, yellow, red, green and white were among the colours shown at the presentation. New cases for the phone will also be released for $29 each.
Pre-orders on the 5C will begin September 13. There was no word on pre-orders for the 5S.
