there are generally tradeoffs, sure.
but battery tends to be not the right input to that.

ask any datacenter operator.

but even on phones.... most often performance is temperature limited, as 
is battery charging.
if you suddenly make the phone hot due to heavy cpu work, your battery 
will charge slower.
And/or you may have less capacity to raise the cpu speed due to the 
system being warmer already.
