Cold Syrup

1. Why does your phone die faster in the cold?
2. Because a battery is a river of ions, and cold turns the river to syrup.
3. The ions move slowly, the phone asks for power fast, and the voltage sags.
4. The phone reads the sag as empty and switches off, with charge still inside.
5. Warm it in your pocket and the river runs again.
6. Where does your phone go in winter?

04). A mountain hut in a snowstorm. A phone on the table; inside it, a cutaway battery where ions are a river of glowing balls running between two plates. Cold: the river turns to syrup, the balls crawl, the voltage needle sags, the phone reads 0% and goes dark with charge still inside. Warm it in a pocket: the river runs again.
