7 things you need to know about the iPhone 6

Everything you need to know about Apple's latest superphone

The iPhone 6 is finally here.

Forget the rumours. Forget the speculation. The iPhone 6, alongside the iPhone 6 Plus phablet, is now official.

Here's everything you need to know.

1. It has a bigger screen

Apple's bumped up the 4in screen size of the 5s and 5c to a substantially larger 4.7 inches. Naturally, the resolution has increased to 1134 x 750 to compensate, providing a ppi count of 326, with a wider overall view.

The display is ion strengthened as opposed to sapphire. While that means it's not unscratchable, it's still toughened glass and should hold up well against the occasional loose change in your pocket.

2. It's got a newer design

The iPhone 6 sees the biggest design change since we saw the 4s evolve into the 5. Despite its larger body to accommodate the bigger display, the overall design is rounder and smoother, borrowing from the iPad school of design.

The power button has also shifted to the right, presumably for easier thumb access. The volume buttons have also adopted the iPhone 5c's elongated pill shape.

Apple has also somehow managed to shave the thickness of its latest iPhone down to just 6.9mm, making the already svelte 7.6mm iPhone 5s sound fat in comparison.

3. It's more powerful than ever

The iPhone 6 is more than just a pretty face. Beneath its sleek exterior beats the powerful heart of Apple's new A8 processor, which Apple tells us is 25% faster than its A7 predecessor.

The graphics chip also has 50% more grunt, and overall the A8 is 13% smaller, thanks to a 20nm manufacturing process.

The M7 motion co-processor has also been upgraded to an M8 affair, which is clever enough to not only distinguish between running and cycling, but can also track elevation, letting you know how many stairs you've climbed.
