I am of the mind to say it makes battery worse seeing as hyperthreading was not made for mobile devices, as far as I know it was for pc processors, which obviously do not need to worry about batteries running out.
But then reading this: http://www.intel.com...technology.html
You could say hyperthreading uses the processor more efficiently thus making tasks easier to do which in turn should use less juice.
I think this will be an interesting one to look into, does it help battery or drain it more ???
