The iPhone 6s is exactly the same height and width as the iPhone 6, but it's also 0.2mm thicker. The difference won't likely bother many iPhone users, but it does seem out of character for Apple, a company that prides itself on steadily slimming and trimming down each generation of its thoughtfully designed gadgets.
The difference in weight will, however, be more noticeable. For example, the iPhone 6s weighs a half ounce more than the iPhone 6 (an increase of 10 percent), and the iPhone 6s Plus weighs nearly three quarters of an ounce more than the iPhone 6 Plus (an increase of 12 percent). The extra heft might be due to new components related to the 3D Touch technology, and it could very well be worth the added functionality. But the weight increases are significant, and again, unlike Apple.
Both new phones are expected to be available for pre-sale on Sept. 12, and they should hit store shelves on Sept. 25. You can learn more on Apple's iPhone 6s Web page.
