THE GOOD Improved speed, better cameras, always-on Siri, and pressure-sensitive 3D Touch display compared to last year's 6 Plus. And it has slightly better battery life, a bigger higher resolution screen, and optical image stabilization for photos and video that can make a difference.
THE BAD It's really big. It costs more than the smaller iPhone. Other phablet-sized phones offer longer battery life.
THE BOTTOM LINE The iPhone 6S Plus has a few key advantages that give it an edge for serious iPhone users, but its big body still may not fit for a lot of people.The width and length usually make more of a difference to me, and my pants. I have pretty large jeans, and my pockets accommodate the Plus fine. Other people I know don't have that luck.
The Plus still doesn't fit easily in one hand, either. I find myself using a pinky tucked underneath.
You do get a 5.5-inch 1, 920x1, 080 resolution display instead of the 4.7-inch 1, 334x750-resolution screen of the iPhone 6S, which matters mostly for photos, videos, and Web browsing. You can fit a bit more of everything on screen at once, as long as apps take advantage( many do, some still haven't upgraded) .
