If you want really long battery life and no heat at all, you can downclock all the way to something like 200-400MHz. A recent CPU at that speed is actually quite usable for things like text editing and reading documentation.
Laptops shouldn't be using boost anyways, because their form factors and CPU coolers just can't handle the heat output.
On the other hand, if it's plugged in much of the time, then let it boost as much as it can, with speed only thermally limited. Otherwise you're not getting the true performance you paid for.
