Update: We have revisited the iPhone 6 Plus almost three years after its launch. It's now packed with iOS 10 and our fully updated review reflects the new features that are packed inside the newest operating system.
Apple's debut phablet is still a winner if you're in the market for a cheaper iOS device with a big screen. But if you're curious to see how it stacks up to the iPhone 7 Plus, we've added that to the competition page. As you might expect, a lot has changed - but there's a lot that hasn't, too.
Has your iPhone 6 Plus exhibited symptoms of the dreaded Touch Disease, like a flickering display? You're in luck. Apple now has a repair program exclusively for the phablet (Sorry, iPhone 6 owners). You can find that right here.
A 5.5-inch iPhone. That might not seem so unusual now, but when it first appeared it was something which would have sent a shudder down the spines of a collective of die-hard Apple fans, as it was a handset some thought we'd never see from the Cupertino-based outfit.
Yet here I am, staring down the barrel of what was once the biggest iPhone in history – the iPhone 6 Plus.
It arrived alongside the iPhone 6 – Apple's 2014 flagship smartphone – which measured 4.7 inches, making it more welcoming to a wider array of palms than the supersized iPhone 6 Plus.
Many of you, especially those of an Android persuasion, may be wondering what all the fuss is about – after all, the Samsung Galaxy Note 2 turned up with a 5.5-inch display a few years before the 6 Plus graced us with its presence.

Take a moment to glance at the history of the iPhone though, and you'll see why the iPhone 6 Plus was such a big deal.
Previously Apple has only dealt in two screen sizes: a 3.5-inch display graced the first five generations of iPhone, and just three have had the pleasure of a larger 4-inch display.
5.5 inches then is a huge leap forward for Apple, moving its iPhone range into the uncharted waters of the phablet market currently dominated by Samsung and other Android manufacturers.
Apple is looking to reach a previously untapped audience of smartphone users – those who demand a large screen – with 'productivity' the main buzzword being thrown around. A key market for the iPhone 6 Plus is Asia, where the general consensus seems to be bigger is better when it comes to smartphone screens.
In terms of specs and design, there isn't a huge amount of difference between the iPhone 6 Plus and the iPhone 6, apart from the obvious size.
The iPhone 6 Plus does boast a couple of unique features however. It was the first iPhone to pack a full HD display, plus its bigger body means it houses a larger battery than its 4.7-inch brother.
Both sport A8 64-bit processors, 1GB of RAM, M8 motion coprocessors and 8MP rear-facing cameras – although the snapper on the iPhone 6 Plus benefits from OIS (optical image stabilisation), while the iPhone 6 makes do with EIS (electronic image stabilisation). This is a much smaller difference than we see in today's batch of iPhones, with the iPhone 7 Plus sporting a dual-camera setup.
iPhone 6 Plus price
As with all Apple products, the iPhone 6 Plus didn't come cheap at launch, but you can expect to find it much more affordable today.
The iPhone 6 Plus is no longer offered on the Apple Store, pushed out by the iPhone 7. However, the last time we saw it on Apple's online shop the SIM-free 16GB version was priced at $649 (£539, AU$1,079) – and that's just the start.
Apple ditched the 32GB variant for both the iPhone 6 and iPhone 6 Plus long ago, so if you're searching for one, you'll probably have better luck finding the 64GB variant in the wild.
There was also a 128GB model, but that's been discontinued as well, so if you need a boatload of storage you'll have to opt for the newer iPhone 6S Plus or iPhone 7 Plus.
As Apple no longer makes the iPhone 6 Plus, new handsets aren't so easy to come across these days. You'll have to take to the likes of Amazon, eBay and other online retailers to find box fresh handsets.
On Amazon we've spotted the 64GB iPhone 6 Plus for $345 (£499, around AU$435) but the price is likely to vary wildly as the last of the stock is snapped up.
