The rumour mill loves an Apple story. It doesn't matter if it's so far fetched it will never see the light of day, or whether it is something that might actually happen, it churns them all out anyway.
The latest claim isn't for one iPhone to be announced in the latter half of this year, or even two, it's for three. And no, we are not joking. These are all the rumours surrounding the iPhone 7 Pro, or iPhone 6SE Pro as it has also been referred to.
We've separated them from the iPhone 7 and iPhone 7 Plus, which you can read about in our separate feature, but for those who want to know about the mysterious third device, keep reading.
Apple iPhone 7 Pro: Release date
The Apple iPhone 7 Pro, as we are calling it, was originally expected to debut at the same time as the rumoured iPhone 7 and iPhone 7 Plus. If this is the case, put 7 September in your diary as this is the date of Apple's next big event.
Apple iPhone 7 Pro: Design
Based on the rumours and the leaked images, it looks like the iPhone 7 Pro will sport a very similar design to the iPhone 7 Plus, but with the addition of a dual-camera setup and the Smart Connector found on the Pro line of iPads.
Japanese-site Mac Fan obtained some schematics for what it claims to be the iPhone 7 Pro, supporting the dual-camera setup and Smart Connector inclusion and a more recent image from Weibo showing all three devices also shows the claimed features.
The schematics show the device to measure 7.3mm, which is the same thickness as the iPhone 6S Plus, as well as what is reported for the iPhone 7 Plus. They also show a device with no headphone jack, which again is something rumoured for the iPhone 7 Plus and iPhone 7.
The image from Weibo showing the three rumoured iPhones side-by-side shows the iPhone 7 Pro and the iPhone 7 Plus to be the same size. All three devices have had their antenna strips moved to the top and bottom, revealing a more seamless metal body.
They also all have "S" underneath the iPhone at the bottom, supporting the rumours that their won't be any significant design changes for the iPhone this year, including the retention of the protruding camera lens.
Apple iPhone 7 Pro: Display
The Apple iPhone 7 Pro should feature the same size display as the iPhone 7 Plus if it arrives at all, and if the leaks are accurate. It's worth bearing in mind that the iPhone 7 Plus and the iPhone 7 Pro could potentially be the same device.
Assuming for the sake of this feature that there will be a third iPhone model released in September however, rumours suggest it will be another 5.5-incher. That will put the 2016 iPhone line-up at four models, with a 4-inch, 4.7-inch and two 5.5-inch devices.
There haven't been a great deal of rumours relating to the iPhone 7 Pro's display specifically, but we can probably expect Apple's force touch technology - 3D Touch - to be included again. The iPad Pro range offers added functionality in its display that allow them to work with the Apple Pencil but there has been nothing to suggest the iPhone 7 Pro will offer the same. If it did, we could be looking at a Note competitor.
Will Apple up the display resolution for the Pro model? Who knows. It's not played the numbers game in the past but perhaps it will want to differentiate the Pro further than just the dual-camera and Smart Connector.
A 2K AMOLED display has been reported for the iPhone 7 and iPhone 7 Plus, which would suggest it will also come to the iPhone 7 Pro if it appears at all. A Quad HD resolution on a 5.5-inch display would put its pixel density at 543ppi, compared to the iPhone 6S Plus's current 401ppi. A switch to AMOLED would also deliver a greater contrast ratio for brighter, punchier colours.
Apple iPhone 7 Pro: Camera
As we mentioned, the Apple iPhone 7 Pro is rumoured to be coming with dual-cameras on the rear. Currently, it is not clear how the setup will work though.
Apple could go down the same route as LG by featuring a standard lens coupled with a wide-angle lens, or it could go down Huawei's route and add a monochrome sensor to the mix. Alternatively, it could do neither and do its own thing, which is probably more likely.
Bloomberg recently claimed the dual cameras on the iPhone 7 Plus will deliver brighter, more detailed images so perhaps the same will apply for the iPhone 7 Pro. Apparently both sensors capture colour differently but take the picture simultaneously, while the device merges the two images for a single photograph. It's been claimed the dual cameras sharpen images in low light environments, while zooming should retain more clarity thanks to the two lenses.
Either way, Apple's iPhone cameras have always performed well so we'd expect no less from the iPhone 7 Pro whether it comes with one sensor on the rear, or two.
The front is likely to see at least a 5-megapixel camera, like the current iPhones, and no doubt the Retina Flash will also be on board, or something similar.
Apple iPhone 7 Pro: Hardware
Aside from the addition of the Smart Connector, which allows for the transfer of both data and power at the same time, there aren't any specific rumours relating to the iPhone 7 Pro's hardware.
It will no doubt come with at least the A10 processor if the device arrives at all. This is what is expected for the iPhone 7 and iPhone 7 Plus too. Whether Apple will choose to put an even faster processor into the iPhone 7 Pro is unclear as we don't even have details on the A10 but it would seem odd for the company to announce two new chips.
The Apple iPhone 7 Plus is reported to be coming with 3GB of RAM, so we would expect the same for the iPhone 7 Pro, if not more. Most competing flagship devices offer 4GB now, with talk of 6GB on its way, but Apple has always avoided the numbers game here too.
In terms of storage, it's been claimed that Apple will ditch the 16GB model for the iPhone 7 and iPhone 7 Plus, suggesting the same will be the case for the iPhone 7 Pro. There has also been talk of a 256GB model, which can be found in the company's iPad Pro range.
Apparently the iPhone 7 Plus will also be upping its battery capacity to 3100mAh, so we'd expect similar for the iPhone 7 Pro.
Apple iPhone 7 Pro: Software
If the iPhone 7 Pro becomes a reality, it will debut with iOS 10, like the iPhone 7 and iPhone 7 Plus.
Like every yearly software update, there are several new features and functions in iOS 10, including a revamp of Messages. You can read more about the new software and what to expect in our separate feature.
Apple iPhone 7 Pro: Will it happen?
This is the big question on everyone's lips. We aren't convinced at the moment but there are certainly arguments for both sides.
Apple currently offers four iPads and no one bats an eyelid so offering four iPhones wouldn't be a completely ridiculous suggestion, not to mention cover most bases. Some of the rumours are also reasonably plausible.
We've seen dual-cameras on other flagship devices and the Smart Connector is a useful feature on the iPad so why not put both on the iPhone?
The only thing we would say is why not just make the Plus, the Pro? Having the option of two 5.5-inch devices with identical designs aside from a couple of extra features seems a little excessive. It will also be very confusing and there haven't been as many rumours of late, suggesting Apple may have changed its mind.
Then again, if the Pro model makes the iPhone appealing to those who currently aren't excited by it, or it gives people a reason to upgrade even though it might look almost identical to the iPhone 6 and 6S, we suppose that's business. Right?
