APPLE'S iPhone 6 is, perhaps unsurprisingly, one of 2014's most hotly anticipated smartphones, and looks to challenge the Galaxy S5, Xperia Z2 and the LG G3.
Building up to its launch, the online rumour mill has spat out rumour after rumour about Apple's next generation smartphone(s), which are widely expected to launch in 4.7in and 5.5in models.
Here, we round up everything we know about the anticipated iPhone 6 handset so far. Keep this page bookmarked, as we'll update it with every new detail, feature and rumour about the iPhone 6.
iPhone 6 release date
If the launch of the iPhone 5S and iPhone 5 is anything to go by, Apple's iPhone 6 is likely to make its debut in September 2014, with last year's unveiling taking place on 10 September 2013. While some rumours have suggested that Apple will do things a month earlier in August this year, we'd take this chatter with a pinch of salt.
The iPhone 6 is likely to be made available a week or so after its unveiling. Last year, for example, the iPhone 5S and iPhone 5C went on sale on 20 September, 10 days after they were announced.
German operator Deutsche Telekom thinks it knows when the iPhone 6 will debut on shelves, telling staff to advise customers that it will go on sale on 19 September.
However, it's worth noting that speculation has suggested that the larger iPhone 6 model could be delayed due to manufacturing issues, and might not see a release until next year.
Despite this, however, Apple reportedly has ordered "70 to 80 million" iPhone 6 units ahead of its launch, which means its expecting it to be its best-selling smartphone yet.
iPhone 6 specs
First up, the display. There have been many conflicting rumours about the iPhone 6 screen size, and some reports have even claimed that Apple is plotting to unveil two 'curved' iPhones in 2014. If these rumours are to be believed, Apple's iPhone 6 will launch in two versions - 4.7in and 5.5in - that will feature flexible displays, much like the LG G Flex.
However, these rumours were quickly debunked, and more recent speculation has claimed that while the displays unlikely will be curved, the will measure in at 4.7in and 5.5in, respectively. The Wall Street Journal, for example, has said that Apple will launch two, non-curved iPhones this year featuring screens larger than 4.7in and 5in.
According to Reuters, the 4.7in iPhone 6 display will go into production in May, followed by the 5.5in panel later in the year.
There's also talk that Apple will improve its Retina display screen resolution with the next generation iPhone, with the firm reportedly set to out the even higher resolution Retina display+. This, if the latest rumours are to be believed, will weigh in with a resolution of 1704x920.
The screen's material is also set for an upgrade, with Apple expected to equip the iPhone 6 with a sapphire crystal display. This, one leaked video showed, could make the the iPhone 6 "impossible to scratch," having withstood keys and a knife. However, a more recent clip has shown that it won't be entirely-scratchproof - failing to pass the sandpaper test - suggesting that the phone's screen will feature a sapphire/glass blend.
It's likely that the iPhone 6 will feature a new design compared to the iPhone 5S and previous iPhone 5, especially if leaked images (below, via 9to5mac) are anything to go by.
There's talk that Apple's iPhone 6 will be crafted from Liquidmetal, lighter than the aluminium that's used for the iPhone 5S. This will allow Apple to make it slimmer too, with rumours claiming that the iPhone 6 could measure just 7.6mm thick.
This same design has been echoed in images leaked by a Taiwanese pop star on Weibo - the same person who leaked legitimate images of the iPhone 5C ahead of its release. He spilled some more details about the design too, saying, "4.7-inch screen, power shifted to the right, no built-in antenna coated outside, in addition to the previous right-angle design, feel more rounded."
We'll likely find the same Touch ID fingerprint scanner as debuted on the iPhone 5S, with multiple reports claiming that Apple will bring the technology to all future iOS device. Rumours have also suggested that Apple might take things one step further by equipping the iPhone 6 with a built-in iris scanner.
Much like the Samsung Galaxy S5, it's expected to have some fitness-focused features too, with the latest rumours claiming that Apple will integrate a heart rate monitor into its next generation earbuds that will ship with the iPhone 6.
There's also talk that the iPhone 6 could be the first Apple smartphone to feature a light up Apple logo on its rear, with the below image showing the redesigned casing. This, if the rumour is to be believed, will light up when a user receives an SMS or email, for example.
There are not many rumours yet regarding what we can expect under the bonnet of the iPhone 6, with last year's iPhone 5S debuting Apple's new 64-bit A7 processor and M7 co-processor. However, some reports are claiming that the iPhone 6 will be the first to feature Apple's yet-unannounced A8 processor, which reportedly will offer longer battery life and subtle speed improvements.
While it's still hazy as to whether the handset will feature upgraded components, we do know, however, that the iPhone 6 will feature Imagination Technologies graphics, with the two firms having extended their multi-year agreement.
That's not the only improvement the iPhone 6 will boast under the hood, as speculation has it that the handset will be the first iPhone to feature NFC. This reportedly will allow users to make payments using the device, and could allow for NFC pairing with Beats headphones.
We likely will see an improvement in the camera, however, with speculation suggesting that the iPhone 6 will sport an upgraded 8MP or 13MP rear camera.
Further speculation has suggested that the iPhone 6 will be the first iPhone to support wireless charging, much like the Google Nexus 5, and the first to ship with 128GB storage.
iPhone 6 software
Of course, the iPhone 6 is expected to run a yet to be announced version of Apple's mobile operating system, which will likely launch as iOS 8 at WWDC on 2 June.
Thanks to the online rumour mill, we already know quite a lot about Apple's next generation iOS release. Speculation suggests that the software build will have a greater focus on fitness, with Apple looking to challenge Samsung's Galaxy S5 with its own Healthbook app. Mapping will be another focus, with the firm reportedly overhauling its Maps application with more accurate locations and public transport information.
Thanks to a leaked image of iOS 8 allegedly running on an iPhone 5S handset, that's not all we know. The software will also likely launch with Preview, Textedit and Tips applications, alongside a dedicated wearables app named iWatch Utility. You can read everything you need to know about the iWatch price, release date and rumoured features by following this link.
Split-screen multitasking is also rumoured to be introduced in iOS 8, a feature which would allow iPad users to use two applications on the tablet's screen at once.
However, the leaked images also suggest that Apple won't be redesigning iOS, despite the criticism iOS 7 received.
iPhone 6 price
The price of the iPhone 6 is still unclear, but it likely will fetch around the same as Apple's flagship iPhone 5S. If so, expect 16GB, 32GB and 64GB models of the handset to cost £549, £629 and £709, respectively.
However, speculation has suggested that the iPhone 6 could cost around $100 more than Apple's 2013 flagship, due to its rumoured larger screen size.
If previous launches are anything to go by, the iPhone 6 will also likely get a clean sweep of the major UK mobile operators. On contract, the iPhone 5S was available from around £35 a month at launch. µ
