When I broke my elbow, I was stuck in the emergency room with a phone at 3% battery and no cord or spare battery.A doctor let me borrow his charger so I could get texts out to friends, and they convinced the gift shop to send a cord to my hospital room.And cookies. And iced tea. And stuffed bears.Since then, I've had battery anxiety.I bought a plug-in hybrid car instead of a Tesla because of battery anxiety.And I panic when I see a coworker's shared desktop on Zoom when they're not plugged in and charging.
