I've been thinking about this for nearly half my life: why do our phones always run out of battery at the worst possible moment? In this episode, we trace the journey from the first telephones to today’s smartphones, explore why solar power hasn’t changed the game, and consider what could happen if our devices started harvesting energy from the world around them: body heat, motion, even radio waves. What if our phones stopped being energy-hungry and became energy-aware instead? A conversation about technology, life, and why something as simple as battery life can tell us a lot about the way we live.
