The iPhone 5C features Apple's dual-core A6 processor and 1GB RAM, the same specifications as on the iPhone 5.
However, possibly because the device comes with iOS 7 installed, we found that the iPhone 5C's performance is smoother than the iPhone 5, and that includes one that we've recently updated to iOS 7.
Apple's new multitasking menu works smoothly, apps load almost instantly, and when we spent an entire weekend playing Grand Theft Auto: Vice City we experienced no lag or slowing.
This smooth performance was aided by 4G, with the iPhone 5C claiming to support the most LTE bands of any smartphone available. We used the iPhone 5C on EE's 4G network, reaching peak speeds of around 26Mbps, which added to the handset's slick overall performance.
Of course, it's performance is likely to pale compared to that of the processor found in the iPhone 5C's bigger brother, with the iPhone 5S having an A7 64-bit chip and M7 co-processor.
The iPhone 5C runs Apple's iOS 7 mobile operating system, the most major revamp of the software since the first iPhone was introduced.
iOS 7 looks great on the colourful iPhone 5C, perhaps more than it does on the more metallic iPhone 5S. The reworked app icons, colourful new wallpapers and fun transitions add to the overall "playful" feel of the phone.
Of course iOS 7, much like the design of the iPhone 5C, is bound to divide opinions. However, given that Apple's changes are mainly aesthetic, iOS 7 is instantly recognisable to those who have previous used Apple's mobile operating system, and in our opinion it's a breath of fresh air, with iOS 6 starting to feel dated.
As well as being familiar for previous users of iOS devices, the clean, minimilistic feel of the mobile operating system will be easy for new smartphone users to operate, more so in our opinion than Android or Windows Phone 8. That's clearly intentional on Apple's part, with the firm looking to target new smartphone users with the iPhone 5C handset.
In terms of new features, there are too many to list. The most useful we've found however include: Control Center - a translucent bar accessible by swiping up from the bottom of the screen that offers quick access to controls such as Bluetooth, WiFi, Airplay and Airdrop; Universal Search - accessible by swiping down on any screen, and a vast improvement on Search found in iOS 6; and the reworked Nofications Bar - now offering three different views, Today, All and Missed.
