No they won't, until there is a huge breakthrough in battery technology. And please stop talking about "computer power", because most of computer power boils down to how much data per second a CPU can treat, unless you have a really minimal software design. Data per second equates to energy consumption. Although even today batteries hold quite a lot of power and you can watch it when you break it, lithium battery can be dangerous, so more powerful batteries might not be such a good idea.
