It's VERY hard to understand what you're trying to say.
Would we want a firmware update to increase Vita's battery life? Of course. Who wouldn't? That doesn't mean performance can't increase though. You seem to have some sort of idea that they can tinker with the CPU/GPU inside these handhelds when in reality they can't. Games are made to run on a set of specifications and they can't underclock these components without messing up how these games run.
The only way performance can increase is if the system was underclocked to begin with and these companies remove that in some update.
