Ranked: The best iPhones ever

Which iPhone is the best ever iPhone? We don our ponder caps to identify the winniest of Apple's many wins

Every iPhone has been a great iPhone – and nearly all of them have been excellent. Love 'em or hate 'em, Apple knows how to make fantastic devices.

Many have been game-changers in their time, ushering in hardware advancements, new ways of interacting with gadgets, and software additions that became indispensable. And every single one of them has been influential, considering how often other makers ride their coattails.

In pure quality and ability terms this would be a simple list of newest to oldest, but what's the point of that? Instead we've considered form, function, impact, influence, quality of competition, and any red flags to work out which was the most successful and impressive in its time.

Will the iPhone 6s and 6s Plus turn out to be classic iPhones? Only time will tell. For now let's enjoy Apple's greatest iPhone hits.

10. iPhone 5c

The iPhone 5 was a brilliant phone when it was released in 2012, and it was still pretty great when Apple dressed it up in plastic and knocked down the price in 2013. And those colours! Whether or not you liked them, you have to admit they were daring (or utterly mad) picks by Apple.

But as the only iPhone ever released specifically to be a "lesser than" model, it was hard to drum up too much enthusiasm for its release. It was a year-old iPhone housed in cheaper materials to save a chunk of change, yet it was still a pricey Apple device. If it was your first iPhone, the 5c was probably still one heck of an introduction. But for the rest of us, it just couldn't stack up.

9. iPhone 3GS

When the iPhone 3GS launched in 2009, it was certainly a notable enhancement over the prior iPhone 3G. The "S" stood for speed, and it was surely felt: the 3GS ran upwards of twice as fast as its sluggish predecessor, plus it added a better camera – with video capabilities! – along with voice control.

But in the historical context of core iPhone upgrades, it's arguably the least consequential of the bunch. It doesn't help that it's sandwiched by the upgrade to 3G data on one end and the iPhone 4's beautiful design and Retina display on the other. If you got the 3GS, you surely appreciated the upgrade. If you didn't, well, you didn't miss that much.

8. iPhone 4s

Here's another "S" upgrade that was very nice at the time, but ultimately not as critical in the grand scheme of things. The iPhone 4s built upon the revolutionary design and Retina display of the original iPhone 4, with enhancements to the camera and graphics capabilities. And the revised antenna design avoided the issues some encountered on the iPhone 4.

But the biggest feature addition was that of voice assistant Siri, which… let's face it, didn't end up being as useful as it initially seemed. (That might change with iOS 9; fingers crossed.) Still, we have to give the 4s props for one thing: longevity. It's getting the iOS 9 upgrade this autumn, four years after release, making it the first iPhone to stay active that long.

7. iPhone 6 Plus

Steve Jobs might not have approved in his time, but Apple finally entered the phablet market last year with the iPhone 6 Plus. With a 5.5in display, it's a massive leap over the iPhones of yesteryear, and even a significant bump over the 4.7in screen of the standard iPhone 6.

But it's huge – even larger than some Android phones with same-sized screens or even slightly larger. For some, it's the giant iPhone they've always dreamed of. For others, it's just too unwieldy to handle. We're sure Apple will find the sweet spot in size with future revisions, but one thing's for sure: it's the most tech-packed iPhone to date, thanks to that Full HD screen and the optical image stabilisation in the camera.

6. iPhone 5s

Whereas the iPhone 5c took the iPhone 5 and made it feel cheaper, the iPhone 5s started from that same device and made it markedly better. The Touch ID sensor was the most obvious perk, offering innovative security functionality that worked startlingly well (even if not perfect), but the upgrade to a 64-bit processor also allowed for glossier game and app experiences.

That said, the iPhone 5s launched at a time when Android makers were pushing into phones with much larger, sharper screens, and Apple's phone couldn't help but seem a little dinky by comparison. It was still a great device; it still is today, to be sure. But after the brilliant iPhone 5, the 5s couldn't help but seem a little too familiar.
