"The only thing that's changed is everything," says the slogan Apple unveiled alongside the iPhone 6s and iPhone 6s Plus . It's an attempt to address the perception that the odd-year ‘s' updates to the iPhone line are minimal and uninteresting.

“The only thing that’s changed is everything,” says the slogan Apple unveiled alongside the iPhone 6s and iPhone 6s Plus . It’s an attempt to address the perception that the odd-year ‘s’ updates to the iPhone line are minimal and uninteresting.

Everything that feels obvious now, once didn't. This goes double for smartphones: All the pinch-to-zoom, touch-friendly interactions we now take for granted and marvel at a two-year-old's ability to figure it out, didn't always seem so natural.

Everything great about the iPhone is even greater here, because big screens rule; 4K video looks incredible; 3D Touch is going to be transformative; #rosegold, y'all

16GB is not enough storage; Battery life is fine, but only that; Touch ID kind of ruins the lockscreen

Just like its more compact cousin, the iPhone 6s Plus brings superior imaging, 3D Touch, a beast of a chipset and double the RAM and those surely make it a worthy upgrade. Plus, the screen size and resolution help Apple compete in a segment clearly dominated by Android.

Image 1 of 9 Nearly a year after release, and the iPhone 6s Plus still doesn’t come cheap. The iPhone 7 is just around the corner, so realistically you should probably hold off to see if the new handset offers a significant upgrade – or what kind of impact it has on the iPhone 6s Plus’ pricetag.

Verizon's iPhone 6s Plus ($749; 16GB) is mostly just a larger iPhone 6s , which some people want so they have more room to watch videos and play games. But it also has noticeably better video recording than the Phone 6s, and it's a bigger panel to write and draw on as well.

Excellent optical video stabilization; Big screen is ideal for gaming and video playback; Improved network performance over iPhone 6 Plus

Expensive; Average battery life

It was already indicated in the preview : The new Apple iPhone 6S Plus will noticeably raise the bar in respect of the processor and graphics performance. This assumption was confirmed in our in-depth review. The Apple A9 chip is currently the benchmark in the smartphone segment.

extremely high performance; flawless build quality; high stability; operating concept with a real additional value; convenient display; fast communication modules; excellent GPS module; decent battery runtimes; good cameras with nice features

iOS 9 still a bit buggy; NFC not usable for third-party apps; internal storage cannot be expanded; mediocre low-light camera performance; very high price

The iPhone 6s keeps the same design as the iPhone 6, but packs better cameras, a snappier processor and 3D Touch, a smart new way to get things done in fewer steps. Beyond that, the combination of iOS 9 and some well-built hardware help makes the 6s one of the best iPhones ever made...
