iPhone 6: Here's what you need to know

Apple will start selling the iPhone 6 and iPhone 6 Plus on September 19 and here's what's new to help you decide whether to buy the new, bigger iPhone 6.

Screen
The most important change is that the iPhone 6 comes with two different screen sizes: 4.7" and 5". This is a big step up from the 4" iPhone 5/ iPhone 5S screen. And Apple will continue selling the iPhone 5S and iPhone 5C along with the new iPhone 6.
The resolution of the new iPhone 6 models has also increased. The iPhone 6 has a screen resolution of 1,334px x 750px at 326ppi (pixels per inch), while the larger iPhone 6 plus has a screen resolution of 1,920px x 1080px at 401ppi.
Because of the huge screen real estate, the iPhone 6 Plus will have a landscape viewing mode for the home screen which makes it more like a phablet.

In terms of dimensions of the phone, the iPhone 6 is only 6.9mm thick and weights 129 grams. The iPhone 6 Plus is 7.1mm thick and weights 172 grams. For comparison, the iPhone 5S is 7.6mm thick.


Processor
The new A8 processor that powers the iPhone 6 and iPhone 6 Plus offers a 25% improvement over the A7 processor, while it's 50% more efficient in terms of power usage. Apple has also updated the motion coprocessor which now includes a barometer which is able to measure relative elevation from air pressure.

Cameras
While the back camera has the same number of pixels as the iPhone 5S (8-megapixel), it's a brand new camera and it has some new and useful features. The sensor now has focus pixels which allows the iPhone 6 and iPhone 6 Plus to focus up to 50% faster than the iPhone 5S. This is the same type of technology that has been used succesfuly in DSLR cameras. The focus pixels allows the new iPhone to also automatically focus while shooting videos. This is a great improvement over the previous models.
Speaking of video, the new iPhone models can record 1080p videos at 30 frames per second and 60fps. There's also a new slo-mo mode at 240fps.
There is only one difference between the iPhone 6 and the iPhone 6 Plus cameras, and it's a big one: the iPhone 6 Plus has an optical image stabilisation, while the iPhone 6 has only software based image stabilisation. This means that when you take a picture with the iPhone 6, it uses the data recorded by the motion coprocessor to move the lens. This should allow the iPhone 6 Plus to generate much better pictures, especially in low light conditions where a longer exposure is needed.

The front facing camera (also called FaceTime camera by Apple) has also been upgraded and it now sports a 1.2-megapixel sensor and 720p HD video recording. Also, it now has HDR and improved face detection. Overall, you should be able to take much better selfies now :)

Other changes
The power button has been relocated on the right hand side of the iPhone so it's easy to to use with only one hand.

The iPhone 6 battery is at least as good as the iPhone 5S, while offering some improvements here and there. But the iPhone 6 Plus, due to its size, is able to offer a much better battery life and might be the first iPhone which could last up to 48 hours between charges.



The new iPhones will be available in Gold, Silver and Space Grey and will have three capacity options: 16GB, 64GB and 128GB. Prices in the UK start at £539 for unlocked models. If you're renewing your contract or getting a new one then check with your network provider as the prices vary depending on the plan you choose.
