Your device's battery status can be used to track you online

There are a myriad of ways you can be tracked online - from
supercookies, to canvas fingerprinting and malware. Now you
can add your device's battery status to the list, according to
research by Steve Engelhard and Arvind Narayanan - two
academics from Stanford University. The attack takes
advantage of the HTML5 Battery Status API, which allows
servers to determine when they need to send an
energy-efficient version of a website. It lets them see how
much charge a laptop, tablet, or smartphone has in terms of
time remaining until discharge, and as an overall percentage.
