Apple has announced the latest iPhones at an event in San Francisco as expected, but despite being an S year, the company claims it has "changed everything about the new iPhones". The iPhone 6S and iPhone 6S Plus succeed the iPhone 6 and iPhone 6 Plus, although the two older devices will still be available.
Apple fans will know not to have expected anything too dramatic in terms of design changes for the iPhone 6S and iPhone 6S Plus, but there is more to talk about than we thought there would be when it comes to differences.
Apple said these two new iPhones "may look familiar but we have changed everything", so let's find out what has changed between the iPhone 6S and the iPhone 6 and what remains the same.

Same design, but different material and extra colour for iPhone 6S

The design of the Apple iPhone 6S and the iPhone 6 are almost identical. Not much has changed in terms of design. In fact, they look exactly the same with all ports and buttons remaining in the same place for the iPhone 6S as they are on the iPhone 6.
Apple has introduced a new colour for the the latest device however. Rose pink has joined the colour line up for the iPhone 6S adding to the silver, space grey and gold models available for the iPhone 6.
Apple has also changed the aluminium used for the iPhone 6S, opting for the same 7000 grade it used on its recently launched Apple Watch. It is said to be stronger and lighter than the aluminium used for the iPhone 6.

3D Touch display on iPhone 6S

The Apple iPhone 6S and the Apple iPhone 6 both have a 4.7-inch LED back-lit display with IPS technology. Rumour had it Apple was planning to increase the resolution for the iPhone 6S, but alas, not this time.
Both the iPhone 6S and the iPhone 6 come with a 1334 x 750 pixel resolution, which delivers a pixel density of 326ppi. This is pretty low for this level of the market, with competitors sitting around the 600ppi mark and one even at 806ppi, but we had no complaints about the iPhone 6 display, so we expect to be as happy with the iPhone 6S, especially as there is a difference elsewhere.
Apple has made the iPhone 6S's display a little more interesting. The new iPhone features what Apple calls 3D Touch, which you can read all about in our what is 3D touch feature. This technology knows how light or hard you are pressing the display in order to bring up a new level of interaction and it allows you to do things like launch the selfie camera by holding down on the camera app icon.

The Retina display will also double up as a flash on the iPhone 6S so you will be able to light up your shots on the iPhone 6S.
Apple also announced Live Photos, which all Apple devices will be able to play but not capture. It's not a new idea, but it is new for Apple users. When you take a picture, the iPhone 6S will capture 1.5-seconds before the shot is taken and 1.5-seconds after the shot is taken. When you then go back to look at the image, it will show you the ripple of water or moving cars when you hold down.
Everything else remains the same including the True Tone flash on the rear, auto image stabilisation, auto HDR and features such as burst mode and timer mode.

The iPhone 6S will be faster and last longer

As you would expect, Apple has introduced a new chip under the hood of the iPhone 6S, opting for the new A9 processor with an integrated, always-on M9 motion co-processor over the A8 and separate M8 motion co-processor found in the iPhone 6. This should mean the new iPhone is a faster than its predecessor. Apple claims 70 per cent faster in terms of CPU and 90 per cent faster in terms of GPU.
Storage options remain the same with 16GB, 64GB and 128GB models available. The iPhone 6S still opts for no microSD support so if you need the storage, you've no choice but to splash the cash. Talking of cash though, the new iPhone 6S will be the same price as the iPhone 6.

The iPhone 6S debuts with iOS 9, but iPhone 6 will get it too

The Apple iPhone 6S will debut with iOS 9, which was originally previewed at WWDC in June. The new software brings several new features with it including improvements to Siri and search. Apple has also added transit to Maps in the software, which will be useful.
The iPhone 6 will of course get an update to iOS 9 so the software experience on these two models will be the same.

Conclusion

Apple has made some quite substantial changes from the iPhone 6 to the iPhone 6S, which will come as a surprise to most.
The processor has been upgraded, along with both cameras and camera features, while Apple has also changed the aluminium to make the iPhone 6S stronger (and less bendy) than its predecessor. There is also a new colour and the 3D Touch display makes things exciting.
If you were expecting the iPhone 6S to be dramatically different to the iPhone 6, you'll probably be left a little sad because design wise, it isn't. But for those who kept their expectations low, you've more than likely been given more than what you expected with the new iPhone.Improved camera for iPhone 6S

The camera has also seen some improvements for the iPhone 6S, moving from an 8-megapixel sensor, found on the iPhone 6, to a 12-megapixel sensor. Apple highlighted all kind of technical terms during the presentation but concluded with the fact that we didn't really need to know any of them and that actually all we needed to know was that the iPhone 6S will take better pictures than
