Apple's brand newand have been given a whole host of over their predecessors, but it's the new camera that I've been giving the most attention.
Thewas already one of our favourite camera phones, but with an upgraded 12-megapixel sensor, I was keen to see what the new snapper can achieve.
I've put the iPhone 6S Plus through a series of challenging trials, alongside its main rival the, and the previous iPhone 6 to see how it stacks up.
iPhone 6S Plus vs. Galaxy S6 in outdoor camera shootout
In an unusually sunny West London, the iPhone 6S Plus took some superb shots, with very rich colours and great exposure. It had the iPhone 6 beaten in terms of clarity (unsurprising, given the increase in resolution), and had more natural colours than the Galaxy S6, which erred for a warmer colour tone in many shots.
iPhone 6S Plus vs. Galaxy S6 in low-light camera shootout
When the light dropped, all phones suffered a drop in quality, but the iPhone 6S Plus managed to keep image noise to a minimum while still keeping natural colour tones. The Galaxy S6 was brighter and sharper in some shots, but its white balance fell short, resulting again with an orange colour cast to some scenes.
iPhone 6S Plus vs. Galaxy S6 in selfie camera shootout
Let's be honest, selfies are important, so it's great news that Apple has bumped the front-facing camera on the iPhone 6S Plus to 5 megapixels. Selfies from the phone looked rich, with a good balance between bright outdoor skies and darker shadowy areas. I prefer the tones of the iPhone 6S Plus, although the Galaxy S6 will suit many selfie fanatics more due to its wider-angle lens, which captures much more of the scene.
We now have our full reviews up of both the, as well as the smaller , so make sure to read up on everything you need to know about both phones, including the beefed up processors and the neat new 3D Touch displays.
