Say whatever you want to say, but the Incredible runs multiple apps and services in the background. Also, I read somewhere, I think on the battery conditioning in the tips and tricks, that that last ten percent of battery takes longer to actually charge to full, even if it reads full, it isn't. That could account for it going from 100% to 90% in that short of time. As far as the iPhone goes, I used to own one myself. It only runs one app at a time, and with the incredible running multiple, and only have a 1300mah battery, it's going to go down a bit faster then something running one app at a time, and the battery is 1400mah. Not a big difference, but if the phone could run multiple processes at once, it would probably have more of a drain itself.
