We all know that our cell phones can easily be tracked through our GPS coordinates but a new study conducted by Stanford and the Israeli government proves that they can also track you through your phone’s battery life. 

The new technique, called PowerSpy, gathers information through your phones apps which are privy to your battery’s usage data. Your batteries work harder depending on your distance to cell phone towers, which can also be obscured by buildings or hills, and this gives spies clues to where you might be. If a spy knows your routine, they are able to track your coordinates with 90% accuracy as opposed to 60% accuracy when those spying don’t know your habits. 

For those who don’t want to be stalked: turn off your GPS, throw away your cell phone, never log into anything online and bury all your assets in the backyard.
