> At what point do battery improvements become completely unnecessary?

A week of heavy CPU/GPU use, on full brightness. We should strive for better. I want to go on a trip without carrying my charger.

This is asking for a battery with hundreds of times more capacity, which, regardless of any future advancements in battery tech, would result in laptops with batteries which are hundreds of times heavier, hundreds of times more expensive, and using hundreds of times more materials than they could otherwise be (to say nothing of being hundreds of times more dangerous in the event of a battery failure).
