By taking an iPhone 7 apart, a company figured out the phone is Apple's second-most expensive to date — at least in terms of parts. But that's not the only reason iPhone devotees pay a premium: British analytics firm IHS Markit found that making the 7 costs Apple only about a third of sticker price. Despite those high figures, Apple pulls a tidy profit on each phone. The study didn't account for costs of marketing, packaging or research and development. The launch of a revamped iPhone 8 will be timed to coincide with the first iPhone's 10th anniversary, and the device is rumored to have more exciting features on deck, including an iris scanner. While the iPhone 7 had a few upgrades, they were more incremental, including improved battery performance and a new body. One piece of good news is that IHS Markit confirms that it is — in fact — water resistant.
