Perhaps, but it still amazes me that something like an iPhone with a GHz processor blasting pixels to the screen all day, can run on a wafer thin battery (Mr. Creosote reference for the cognoscenti) for a full day.

Given that humans sleep at night, recharging the phone at night is a reasonable price to pay for the benefit of a smartphone vs flip phone, but a device that needed charging during the day as well (e.g. due to a form factor with a tiny battery) would almost certainly be a product killer.
