Your Phone's Battery Can Tell You Site-Specific Weather

We first brought you OpenSignal’s crowdsourced weather data from Weather Signal in May, but since then, the team have discovered that there was a correlation between your phone’s battery and the weather outside. It’s not black magic after all!

Of course you don’t need an app to tell you how hot it is, unless you live in San Francisco, where a five minute walk can have you adding layers faster than you can say fog.  The weather here is based on microclimates, and no matter how much predictions you are given, non are as useful as real data, from someone down the street.
