As reported by The Guardian [http://www.theguardian.com/technology/2015/aug/03/privacy-smartphones-battery-life], a paper entitled The Leaking Battery [http://eprint.iacr.org/2015/616.pdf] by Belgian and French privacy and security experts say that the API can be used in device fingerprinting. The API can be used to determine the capacity of a website visitor's battery, as well as its current charge level, and the length of time it will take to fully discharge.
