In a sense, "draining the battery" is the entire point of a high-performance graphics plugin and it ought to be the user's decision whether or not to play Flash games based on their need for battery time. So I suspect "it drains the battery" is covering for a deeper issue, like perhaps: were we getting good value from Flash?
