You could argue that the iPhone can get away with having significantly weaker specs than most Android flagships because of the optimization that iOS allows, and you wouldn’t necessarily be wrong, but two things that no amount of optimization can make up for are the iPhone’s camera and resolution. While we’ve already heard rumors that Apple will finally upgrade the iPhone’s camera with the iPhone 6S, another rumor claims that the next-generation iPhone will adopt Full HD resolution, while the Plus version will feature a 2K display.
