Summary
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. even if we wish it had some of the 6s Plus’ niceties.
The iPhone 6s Plus has 3D Touch, iOS 9, a pair of improved cameras and the powerful A9 chipset, just like its smaller sibling. A long-lasting battery and optical image stabilization for its 12-megapixel rear camera help give the iPhone 6s Plus a slight edge over the regular 6s, although we wish it were a little easier to hold.No, your eyes don’t deceive you: The 6s and 6s Plus look nearly identical to last year’s models, save for a new rose gold color option that oscillates between "vaguely lavender" and "shiny new penny" depending on the light. The sleek, rounded aesthetic might not raise as many eyebrows as it did last year, but it’s still one of my favorite iPhone designs. Aside from the pink color option, the other changes aren’t particularly noticeable. Both phones are now made from 7000-series aluminum, an alloy used in the aerospace industry that, when compared to last year’s phones, makes for a sturdier but similarly lightweight design. The regulatory icons that used to live on the iPhone’s back have been removed too, leaving a teensy "S" logo to let the world know you’ve upgraded.
