Go and have a look at, say, Sammy. There is not a lot of heavy duty stuff gong on in JS-land. Particularly on a phone, the amount of JS required is tiny; certainly not enough to impact power consumption unless one is completely incompetent. Also, try phonegap or jquerymobile. Tons of functionality that is immediate and battery friendly. You _can_ do this stuff badly, but that's not what we're talking about here.
