How your phone's battery life can be used to invade your privacy

  It looks like this is just another piece of data for [browser fingerprinting][0]. So, it's serious, but since there's already enough information available to uniquely fingerprint any browser the, um, marginal impact, I guess, isn't very high.

    I suspect the marginal impact might be pretty high in certain cases. For example, it looks to me as if on iOS you can only be identified down to (browser * iPhone model * iOS version * timezone). I'd venture a big majority of iPhone users use Safari, most iOS users update their OS fairly quickly, and there aren't that many iPhone models. So battery life could make a big difference there.

      That's a good point which I hadn't thought about. It's probably less true for Android, but still more than for desktop.

  In Firefox, maybe turning dom.battery.enabled to false could help (in about:config).
