So, I’m going to college up in the catskills of New York, meaning it’s currently about 7°F where I am.
I went on a walk the other day with my DAP, and noticed it randomly rebooted in the cold, but then worked fine inside. I figured that was just one of the perils of niche, low volume android devices, but just today my well-built smartphone died randomly at 50% battery and refused to reboot.
I get that this has to be something with battery, but I thought it was supposed to be heat that killed batteries. And besides, I don’t remember my Gameboy Advance ever dying of frostbite.
In: Technology
A battery is chemical storage for electrical power. That means that the electrical power is provided when chemical reactions (specifically, electrochemical reactions) occur, which are reversed when charging. Cold temperatures can slow down the rate of chemical reactions; this would, in turn, reduce the power output of the battery. In cold enough weather, this might be enough to stop the device from working, as it cannot draw enough power to function.
