It happens to almost everyone at some point each winter. You are out in the cold, you pull out your phone to check a map, and the screen goes dark, even though it showed forty percent battery only moments earlier. Had the battery been lying to you? In a sense, yes.

Inside every phone sits a lithium battery, which is less a tank of stored electricity than a small, ongoing chemical ...

Inside every phone sits a lithium battery, which is less a tank of stored electricity than a small, ongoing chemical reaction. Power is generated as particles migrate between the two sides of the battery, and like most chemical processes, that migration slows down considerably once the temperature drops. In freezing air, the particles move so sluggishly that the battery cannot deliver power quickly enough, its voltage collapses, and the phone, reading that drop as an empty battery, switches itself off to protect its circuits.

The proof arrives the moment you step back indoors. The chemistry warms up, speeds up, and the very same phone switch...

The proof arrives the moment you step back indoors. The chemistry warms up, speeds up, and the very same phone switches back on showing perhaps thirty percent, as though nothing had happened at all. The energy had been there the whole time, merely trapped behind a sluggish reaction. Which is why, in winter, it pays to keep your phone in an inner pocket, close to your own body heat: the battery is not actually weak, it is simply unenthusiastic about your weather. Warmth, not charge, was the missing ingredient all along.
