Why iphones are so expensive ?

iPhones are expensive relative to many Android phones for a couple reasons—first, Apple designs and engineers not only the hardware of each phone, but the software, too. Apple crafts and controls the entire user experience. Historically, competitors like Samsung have built the handsets, and used Google’s Android operating system to run them. Carefully integrating software and hardware is more resource intensive, and thus, naturally, raises the price of the phone.

As we all know 

Apple also continues to position the iPhone as a higher-end product, which, while keeping it from being a major player in some major developing markets like India, allows the company to reap much higher profit margins on each phone than its competitors. The gambit has worked, thus far: the iPhone is the most profitable product in modern history.
