APPLE HAS UPDATED its flagship smartphones with the launch of the iPhone 6S and iPhone 6S Plus . The handsets have already been well received by the market, shifting a record 13 million units in their opening weekend - although this record is partly down to the inclusion of sales across China.

Outstanding design and build quality; 3D Touch is a major step forward; New camera; video capabilities are impressive; Taptic Engine is unsung hero

Battery life same as before; Low-light photography no better than iPhone 6; 16GB as base model is pass; Charge times could be improved

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's interim ‘s' phone reaches its sixth iteration, but can it be more than just a precursor to the inevitable iPhone 7

Excellent screen; Blistering performance; 3D touch more than a gimmick

Screen flash feels gimmicky; No battery life improvement; No optical image stabilisation

A technically impressive, solid smartphone with a healthy helping of touchscreen innovation, ultimately let down by poor battery life. iPhone 6 users may want to wait for next year's model, but the 6s is a good upgrade choice if you're still using an iPhone 5s or earlier.

Is iPhone 6S a great phone? Yes, it is. It does have its unique features and they promise a great deal in future updates. Is it worth upgrading over iPhone 5S? The users of iPhone 5S are the main target, the iPhone 6S being leagues ahead from all points of view (better camera, larger screen, better...

3D Touch; Still a great design; Great performance; Good camera performance; Stable OS

No microSD card slot; Low battery life; No optical image stabilization; Price is quite high

We're not sure that statement would hold up in court, but what certainly hasn't changed is Apple's undeniable way of making a great handset even better.

Wonderfully slick in use; Great with video and audio; 3D Touch is surprisingly intuitive

Screen resolution behind some rivals; Not compatible with high-res audio

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
