Here's one thing we'd bet our house on: the iPhone 6 will have a larger (probably 4.7-inch) screen along with a 5.5-inch iPhone Air, as mentioned on the previous page - with both being a lot thinner thanks to big improvements in LED backlight technology to reduce the thickness.
Apple has even acknowledged that consumers want a larger screen after an internal slide was revealed in its court battle with Samsung entitled "Consumers want what we don't have."
While we'd love to see the Quad HD resolution adorn the iPhone 6, the fact it's such a great leap from the sub-720p Retina display on the 5S and 5C makes it seem very unlikely.
More recent resolution rumors come from insiders who claim that Apple has been testing a pixel-tripling display which would have a resolution of 1704 x 960.
That's not quite full HD, but it would allow the phone to retain the iPhone 5S's 16x9 aspect ratio and give the 4.7-inch iPhone a pixel density of 416 pixels per inch and the rumored 5.5-inch phablet a density of 355 pixels per inch, both of which trump the 326ppi screen of the iPhone 5S.
Based on information found in the iOS springboard it's also possible that the next iPhone will have either an 828 x 1472 or a 1242 x 2208 resolution according to 9to5Mac.
There is a chance that our eyeballs could be in for a real treat though, with Apple employees apparently quoted in Hong Kong saying that the iPhone 6 will sport a QHD resolution (2560 x 1600) - the same as you find on the LG G3.
That would be impressive, although rather unlikely if you ask us. All the rumors point to an increase in resolution though, so even if it's not quite that good the iPhone 6 screen is likely to impress.
There have been more iPhone 6 leaks than ever before this year - it seems Apple is unable to keep a lid on production any more.
A leak from ifanr.com gives us a very clear look at what's believed to be a final or near final version of the iPhone 6 front panel.
It's clear from the images that we are looking at a screen of around 4.7 inches as has long been rumored and it also has slightly rounded edges, which may allow it to arc seamlessly into the chassis. The source of the leak also claims that the display might be made out of sapphire.
The front panel image slips keep happening, with a series of shots appearing on MyDrivers, again showing very similar looking components against the smaller frames of the iPhone 5.
A shot of one of the panels being held in the hand shows the extra girth the iPhone 6 could be carrying, and you may need to do some hand exercises to ready your palms for a larger iPhone.
An unbreakable display
Here's an interesting one: Apple looks like it's signed a big deal to use a lot of sapphire glass in its phones, with the company buying up enough to use the super-hard technology for its displays.
Sapphire is already used by the Cupertino brand for its Touch ID sensor cover and the camera glass, so extending it out makes a lot of sense. Whether it will be cost effective remains to be seen - but given iPhones are one of the top devices for broken screen repair, reducing this problem would go down nicely.
However, there's an issue here: it's really expensive, and as such seems like it would bump up the cost of the phone too much for Apple, even though its customer base expects to pay a premium.
The sapphire rumour just won't die though, as there's now a video purportedly showing an iPhone 6 display and at one point it's bent between two hands, which doesn't necessarily mean it's sapphire but it's something which wouldn't be possible with Gorilla Glass.
While another video demonstrates just how strong it is, by attacking the supposed iPhone 6 display with keys, a knife and more - a display which apparently looks like Sapphire glass according to Professor Neil Alford of the department of materials at Imperial College, London.
It may only be partially made from sapphire though,as another video puts it up against sandpaper in a battle that the screen loses, which it wouldn't have done if it was pure sapphire, which tallies with other reports like those from LEDinside.
A recent video of the iPhone 6 also suggests that the display isn't sapphire, or not fully sapphire anyway, with the commentator theorising instead that it's either partially sapphire or just tempered glass.
As such, this means it's likely that the sapphire glass hasn't made it to final production, with the front instead just getting a massive bump in strength. This would put it on a par with the rest of the market though, and would still reduce the amount of cracked iPhone screens you see around.
It might not matter too much if it does get scratched though, as we're also hearing that it could even self heal, with Apple trying to patent a special screen coating that could heal to dramatically enhance the appearance of the iPhone 6, as well as other Apple products.
iPhone 6 specs: NFC on the way
What's this? NFC in an iPhone? About time too. New leaks state this is finally happening in the new iPhone 6, and Apple has been busy creating a reason for it too.
It's a theory that's looking ever more likely as it's now been revealed that Apple has partnered with China UnionPay to add its banking service to Passbook. That in itself needn't mean NFC, but apparently users will also be able to make payments on China UnionPay's QuickPass machines, which use NFC.
Many Android phones now boast NFC and Apple appears to have been happy to be left behind here, so we'd be a little surprised to see it suddenly rocking the contactless technology when it appears to be on the wane.
Then again, the evidence for it is mounting and with images showing a cut-out where the Apple logo would be it's possible that NFC will be embedded into a non-metal logo.
We've also seen an image of an iPhone 6 logic board which according to Nowhereelse.fr proves the presence of NFC and a leaked schematic, which appears to show an NFC chip, while a new video also highlights an NFC module, so file this one under likely.
Not only does it look like the iPhone 6 will have NFC, but we even have an idea of what it's going to be used for, as Re/code reports that Apple has partnered with American Express to allow users to pay with their phones in physical stores.
It also looks like a 128GB version of the iPhone 6 (needed if the rumours of a much higher-res screen are to be believed) will be offered to cater for the larger apps and more photography many will be doing - it's not going to be cheap, though, and will be the most expensive iPhone yet.
Meanwhile Touch ID is unsurprisingly expected to make a return, but sources claim that Apple is making the sensor more durable this time around. We're not sure how durable something that you lightly press your finger against really needs to be, but it could mean that the accuracy will be further improved for fewer missed presses.
We've also now had our first look at what might be the iPhone 6 Touch ID sensor. The photo was shared by ASCII.jp and shows two sensors. The top one is taken from an iPhone 5S and the bottom one is, well, not. That doesn't necessarily mean it's an authentic iPhone 6 one but it certainly looks different, so perhaps it's the more durable redesign we've heard about.
The iPhone 6 could save your life - with iOS 8
Apple has already lifted the lid on iOS 8 at its WWDC 2014 conference in San Francisco and going by previous iterations of the software it'll arrive alongside a new iPhone.
The much rumored "HealthBook" does make its way to iOS 8, but with the slightly altered name of "Health."
This app can pull in data from various health monitoring applications, providing you with one centralized sourced to view all your vital statistics, while the HealthKit developer tool will allow applications to make greater use of this function.
With the Health app now on the scene, reports that the iPhone 6 will apparently come with an array of sensors to monitor your health and environment begin to look far more credible.
iPhone 6 power
Not a huge surprise, this one: the next processor will be an A8. The big sell here is more power with better efficiency, which should help battery life, as well as being incredibly powerful for gaming. If you saw the demo on stage at WWDC, you'll know that the new iPhone is going to be very capable at rendering beautiful games.
There were thoughts that it might be quad-core, but recent rumors suggest Apple will stick with a dual-core chip, albeit one that's much faster at 2GHz (the iPhone 5S is 1.3GHz) which will allow for a noticeably faster response time and graphics rendering.
It will also apparently be made using a 20nm manufacturing process, meaning that it will be smaller and more efficient than the 28nm processor in current iPhone models.
Anyone hoping for some juicy Samsung technology hidden under the iPhone 6 body will be disappointed though, as reports suggest Apple is looking to push its Korean rival further out of the iPhone picture with its eighth-gen handset.
Apple is apparently cutting the amount of A8 processors it is having made by Samsung, although it hasn't severed ties completely just yet.
There's not been much word on how much RAM the iPhone 6 will come with, but KGI analyst Ming-Chi Kuo reckons it will have 1GB, just like the iPhone 5 and iPhone 5S before it - which would be a shame given there's a 64-bit architecture to the chip, which can't be exploited properly under 4GB of RAM.
It's also possible that the 5.5-inch model will be more powerful than the 4.7-inch one, as according to AppleInsider, supply chain checks from analyst Timothy Arcuri suggest a more powerful processor will be included in the 5.5-inch handset, though there's no word on how much more powerful.
Expect the iPhone 6 to support speedy data too, as both versions are rumored to have a Qualcomm MDM9625 chip, which supports LTE-Advanced. However it doesn't have Cat 6 support, so it caps out at 150Mbps, while in theory Cat 6 LTE-A devices will be able to download data at up to 300Mbps.
On the storage front it's been reported that for the first time we might get a 128GB iPhone, but that only the 5.5 inch iPhone 6 will reach that capacity, while the 4.7-inch model will be capped at 64GB.
The battery could be getting a boost too, as IT168 reports that the 4.7-inch model will have an 1800mAh power pack (which is a 15% increase in capacity over the iPhone 5S) and the 5.5-inch handset will have a 2500mAh unit, which is a huge 60% increase over the iPhone 5S. Of course with the phones also getting larger and more powerful that won't necessarily translate to a huge boost in life.
We've now seen an image purportedly showing an iPhone 6 battery courtesy of Nowhereelse.fr and it comes in at 1810 mAh, essentially matching previous rumors.
