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.

    I guess that it could also be used to compare different people. Do they have fast and slow connections at about the same time? Then they might be spending time together.

    This is clearly not for mass espionage, but at least a theoretical approach to confirm a suspicion.
