The 3rd hand story I heard ~2011 from a former RIM executive who was there at the time of Steve Job's demo of the iPhone was that Mike Lazaridis' (co-founder of RIM) reaction to seeing the demo: "It's impossible! The whole thing would have to be a battery!"
He's right, it is impossible for the iPhone and clones to match the blackberry's batter life. It turns out any (certainly not all but few enough to keep blackberry in the market) prefer 60FPS scrolling to having the battery last a week.
