When is the next iPhone 5c coming out? It's likely that Apple is considering a new version of its cheaper iPhone, which could be called the iPhone 6c, but there is a lot of doubt surrounding the smartphone. Here, we'll be bringing you all of the latest iPhone 6c release date speculation, rumours about the new features the iPhone 6c could have and iPhone 6c leaked images and mockups from around the web.

There's so much talk about the iPhone 6 already, but not so much about the iPhone 6c, which is what we're calling the successor to Apple's iPhone 5c, the iPhone 5s's (marginally) cheaper and (massively) more colourful sibling. We think it seems inevitable that the iPhone 6c is going to happen, though, following Apple CEO Tim Cook's comments on the success of the iPhone 5s during an earnings call in January, the fate of the iPhone 5c is in question.

What's the next step for Apple's 'c' series iPhones? Will Apple bring new colours for the iPhone 6c? Will it get new features such as a camera upgrade, a processor boost or a design tweak? Or will Apple ditch the 'c' series already? Here, we discuss the rumours. We'll update this article as soon as we find out more about the iPhone 6c, so check back regularly for the latest information. See: Is the iPhone 5c really a flop?

iPhone 6c release date

There's widespread debate about the future of the iPhone 5c following Apple's 27 January financial call for the first quarter of 2014. During the call, Tim Cook effectively acknowledged that the sales of the iPhone 5c were not as high as expected. "It was the first time we'd ever run that particular play before, and demand percentage turned out to be different than we thought. We sold more 5S than we expected," Cook said, tacitly admitting that the iPhone 5c under-performed.

When asked about the pricing strategy of the iPhone 5c, Cook said: "If we decide it's in our best interests to make a change then we will make one. We're willing to make any product that's a great product."

Combined, these comments sparked speculation that Apple is considering a price drop for its next iPhone 5c, or alternatively, that its considering ditching the iPhone 5c already.

Piper Jaffray analyst Gene Munster said: "Demand has not been good. [Apple] will discount it and use that as a lever to improve unit growth. I don't think they will get rid of it completely."

However, Jefferies analyst Peter Misek thinks the iPhone 5c has a short life-span ahead of it. "I would expect them to cancel the product after the iPhone 6," he said. "Price cuts are not what Apple does. They build products that they are passionate about and then charge accordingly."

We think it's also possible that Apple will decide not to update the iPhone 5c in 2014, but rather wait until 2015 when it releases what will presumably be called the iPhone 6s. That way, when the iPhone 6 arrives later this year, the iPhone 5s would be reduced in price and the iPhone 5c even more so. See: Bigger iPhone release date

iPhone 6c images

While there are no leaked images of the iPhone 6c, designers have been busy creating concepts of the device. The fact that there are no leaked images of a new iPhone 6c is evidence in itself though. We've seen so many leaked iPhone 6 images that it's highly likely we would have seen an iPhone 6c leak by now if one was in the works alongside the new flagship.

The most recent iPhone 6c concept, and definitely the most appealing yet, is a new concept video by designer Joseph Farahi (below). He's imagined a 4.7in iPhone 6C with colourful plastic chassis just like the iPhone 5c.

SET Solution thinks that the 'c' in iPhone 6c could stand for Curve, so has created a video to show what a curved iPhone 6c could look like.

We quite like iPhonesoft.fr's iPhone 6c concept, which is slimmer and has an edge-to-edge display.

Designer Martin Hajek has also created a similar concept image, as shown at the top of this article.

Other iPhone 6c rumours

Aside from the release date speculation and concept images, there isn't much chatter about an iPhone 6c yet, but this is where you'll find all of the latest rumours as they arrive on the web. We'll be updating this article regularly.

For now though, it's easy to imagine the changes Apple may decide to make to the iPhone 5c should it decide to continue the product line.

The iPhone 6c could have additional, or different, colours. The five colours used for the iPhone 5c are on-trend for the year 2014, but will they still be fashionable next year? If not, Apple may decide to update the colours to suit new fashion trends.

It's also likely that a new iPhone 6c would have an improved camera and processor, and would possibly also be thinner and lighter than the current model. As it stands, the iPhone 5c is slightly thicker and heavier than the iPhone 5s, at 8.97mm and 132 grams compared to the iPhone 5s's 7.6mm and 112 grams.

If Apple decides to introduce the widely rumoured edge-to-edge display with the iPhone 6, it's possible that the iPhone 6c will get the same treatment, too.

It's likely that the iPhone 6c will get iOS 8, which Apple unveiled during its WWDC 2014 keynote. You can find out more about iOS 8 here.
