The whole isn't the fastest, the biggest comes up with big caveats. For example the iPhones don't have the longest battery, but the phone that has the longest battery has two times the amount of battery, while having a much higher consumption than iPhones. If Apple decides to stick a 5000+ mah battery in an iPhone - Android phones would have no way of catching up to its battery life. Another big thing being the latest screen tech - Apple can't afford to do an OLED screen on the iPad, since Samsung and LG can't possibly manufacture enough OLED screens to meet demand. Where Samsung is perfectly fine doing it, when they won't sell enough tablets to matter. In the end it's not that the iPhone is clearly inferior to Androids, it's mostly that Apple has some numbers in mind that they consider optimal and going beyond those won't increase their sales (certain amount of battery, certain screens, etc).
