Honestly, I'm quite paranoid myself and it probably wouldn't have occurred to me that such a nice little feature could pose a risk to the users' privacy... Let's see if and how the W3C responds to this.The battery status API is currently supported in the Firefox, Opera and Chrome browsers, and was introduced by the World Wide Web Consortium (W3C, the organisation that oversees the development of the web’s standards) in 2012, with the aim of helping websites conserve users’ energy. Ideally, a website or web-app can notice when the visitor has little battery power left, and switch to a low-power mode by disabling extraneous features to eke out the most usage.
