I’ve read the article - but what can an attacker actually DO using this technique? Drain battery? The article mentions ‘tracking’, but in what way?

    The article states patterns could be drawn from response times. Fast response times could indicate a high-availability, low-latency network (such as being at home), where longer response times could indicate the phone is away from that network, whether on the road or at a store or business, etc.
