I love the iPhone 6S. There, I said it. If you want a phone that's always going to be by your side, that will never argue with you and that will look as good as your smug little face while using it, then the iPhone 6S is for you.

A class-leading camera and 3D Touch bring major new functionality to the gold standard in smartphones.

More powerful than iPhone 6; 3D Touch livens up iOS 9; Major camera upgrades; front and back; Stronger aluminum construction; Crisp; gorgeous screen

Smaller battery than iPhone 6; Entry-level 16GB model is insufficient

For this generation of iPhone Apple's tagline is, "The only thing that's changed is everything." Based on our experiences with the iPhone 6s this is only really a half-truth and the implications of it aren't always for the better.

Great cameras; Stunning screen; Blazing fast performance; Best app experience

Apple launched the iPhone 7 and iPhone 7 Plus , but what's new? Check out our iPhone 7 vs iPhone 6S if you're looking to upgrade, but the short version is quite a few things. While the overall look is very similar, it's now waterproof and comes in a few new colours.

Great look and feel; 3D Touch adds interesting new dimension; Subtle but useful camera improvements; Outstanding performance; Clever front-facing camera flash

Battery will deter power users; No wireless charging; Others charge faster

While the launch of an ‘s' model iPhone is generally more of an update than an overhaul, there are actually quite a few new features in the iPhone 6S to get excited about.

Great 12 megapixel camera; fun video modes including 4K; 3D Touch; powerful

Pricey

An iPhone with an "s" in its name is never quite as exciting as one with a new number. The "s" years don't bring slick new form factors but iterative improvements. A bump in RAM or a jump in camera specifications is useful, but it's much easier to get enthusiastic about a change in design.

3D Touch is a meaningful innovation; Amazing cameras; 2GB of RAM makes the iPhone 6s zippier

Battery may underwhelm power users, Still starts at 16GB, More expensive this year thanks to Aus; dollar

The iPhone story for 2015 is remarkable in that it is an ‘S' year, which usually means incremental changes with no obvious physical difference from last year's model, but Apple's given the iPhone 6S a complete structural and functional makeover.

Our conclusions for the iPhone 6s on T-Mobile still hold for the Verizon model, although a little less emphatically. Despite almost identical looks, the 6s is still a considerable step up from the iPhone 6. It's faster, it has better cameras, and 3D Touch shows potential.

Recovers from dead zones faster than iPhone 6; Excellent cameras; Super-fast processor; 3D Touch has lots of potential

Front-facing camera could be sharper; Average battery life

Big changes have been made to Apple's iPhone 6s. The naked eye will consider this smartphone identical to its predecessor with its eerie, twin-like looks, and yet this generation's model represents a substantial step forward, from the fabric of its metal body to the computing components that...

Improved construction; 3D Touch will reap genuine benefits; Faster processor and double the RAM; 12MP rear and 5MP front camera; TouchID is among the best finger scanners

Cameras lack OIS and could be higher in resolution; Battery life still lesser than rivals

The Apple iPhone 6s has a strengthened exoskeleton that employs aerospace-grade 7000 Series aluminium and glass which, according to Apple, is the strongest and most durable used in any smartphone.
