It's looking increasingly like we'll see three iPhone models released this year, with an iPhone 6C launching alongside the inevitable iPhone 6S and iPhone 6S Plus.
While the iPhone 5C was designed purely as a more affordable iPhone, the iPhone 6C is likely to have more to differentiate it, with a smaller screen than either of the 6S models.
Currently the only way to get an iPhone with a 4.0-inch screen any more is to buy the 18-month old iPhone 5S or iPhone 5C, both of which may well be discontinued with the launch of the next wave of devices, especially if we do get an iPhone 6C, so it will likely be aimed both at those who want to save some money and those who want to save some pocket space.
We don't know a huge amount about the iPhone 6C yet, with most rumors focusing on the flagship 6S and 6S Plus, but we are starting to hear a few things and for everything else we've got a hefty wish list.
It may also share some specs with the iPhone 6, as it's rumored that the colourful handset will ship with an A8 processor, though while that's at the top end now bear in mind that the iPhone 6S will almost certainly have a newer, faster chip, marking the iPhone 6C out as a lower end phone.
It's also rumoured to have NFC and Touch ID, which sould mean Apple Pay support, and of course if it launches this year it will run iOS 9. The rest of its specs are completely unknown, but there's a good chance it will borrow liberally from the iPhone 6, given that the iPhone 5C stayed very close to the iPhone 5.
What we want to see
1. Touch ID
While the iPhone 5S has Touch ID, the iPhone 5C (which launched alongside it) doesn't. Two years on it's unlikely that Apple would keep it out of the iPhone 6C, but it is a worry, especially as the phone is likely to be positioned as a budget alternative to the iPhone 6S.
We really, really hope that doesn't happen though, as it's one of the best recent iPhone features and not having it would severely limit the iPhone 6C's appeal. Thankfully its inclusion has already been rumored.
2. A powerful processor
As a budget device we don't expect the iPhone 6C to match the iPhone 6S, but we hope it comes close, especially as it's likely to be the best 4-inch iPhone around.
Buyers who want a smaller phone shouldn't be overly penalised on specs so we'd like to see high-end performance from the iPhone 6C. Current rumors point to it packing the same chip as the iPhone 6, which should just about cut it.
3. A 4.0-inch screen
While it's expected that the iPhone 6C will have a 4.0-inch screen it's not actually confirmed, but we really hope it does.
If Apple only released one iPhone size we'd want it to be the now standard 4.7-inch model, but choice is always good and we'd wager there are many Apple fans who were disappointed by the move to larger screens, so a new model with a small screen would be much appreciated.
4. A more affordable price
While the iPhone 5C was designed to be a comparatively budget option it wasn't and even now still isn't particularly cheap.
So we'd like to see the iPhone 6C be truly affordable. Perhaps not entry-level, but with a mid-range price of around £300/$400/AU$500.
5. A more premium design
One of the cost cutting measures employed with the iPhone 5C was to replace the premium metal and glass builds of other iPhone models with a colourful plastic shell.
It's a solid, well-built phone, but it undeniably looks far less premium or stylish than other Apple handsets.
We'd love to see Apple not skimp on the build materials with the iPhone 6C. Of course it's very unlikely that we'll get both a premium build and a lower price, but we can dream.
6. A slim build
Given that the iPhone 6C will likely be more compact than the iPhone 6S it would be great if Apple went all out and made it simmer too, so it's truly as pocket friendly as possible.
The iPhone 5C is 9mm thick, but we'd like to see the iPhone 6C drop down to around 6.9mm thick like the iPhone 6.
7. Plenty of storage
The iPhone 5C was initially sold in several storage sizes, but it's now just available in a near useless 8GB model.
Given that Apple doesn't allow for expandable storage 16GB is the absolute minimum that we consider acceptable and even that's pushing it these days. So hopefully the iPhone 6C will be available with a range of storage capacities and if 32GB was the smallest we wouldn't complain.
8. Better battery life
The iPhone 5C has respectable battery life, but it's still a phone you'll be charging every night, so we'd like to see the iPhone 6C have longer life.
Very few phones last as long as we'd like, but we've seen from the likes of the Sony Xperia Z3 Compact that two days is possible, so we want to see that from the iPhone 6C.
