> A laptop/phone that needs to be recharged every few weeks… heaven. Agreed. Unfortunately it seems like increases in battery density are soaked up by either increased energy consumption (screen resolution/brightness, processor) or decreased battery volume to make a thinner device. I have a smartwatch that doesn't require wall charging (a Garmin Instinct with solar) and I really like the combination of solar cells, low-power processor, monochrome screen, and frugal radios. That got me curious about a low-powered laptop and I've been eyeing an e-ink tablet with keyboard (e.g. Boox Tab or Remarkable 2) but I think it'd be a little too limited for my laptop usecases. And all the super-energy-efficient phones (e.g. e-ink) I've seen simply shrink the battery volume to offset any efficiency gains.
