Dual Survival Uses of Your Phone Battery

Your phone battery can literally save your life in a wildfire and nobody talks about this.

If you're trapped and need rescue, take off your phone case and use the shiny battery as

a signal mirror to reflect sunlight toward helicopters or planes. The metallic surface

creates flashes visible for miles. Here's the twist though. That same battery

can start a fire if you're freezing. Touch steel wool or gum wrapper ends to the terminals

and it ignites instantly for warmth. One device, two opposite survival uses depending on

what's trying to kill you. Most people die waiting for help they could've signaled

for, or from hypothermia with fire-starting tools in their pocket.
