Monitor your network traffic.
Lots of people do this already for various reasons and haven't noticed anything like this going on.
Yeah, sure, I can brute force encrypted traffic by eyeballing it in my router's dashboard UI. Come on, dude.
You seem to have an axe to grind here and I refuse to participate. I even objectively admitted that I can't know and that I only suspect yet you (a) offer a non-solution and (b) likely downvote a comment because you don't like it.
Sheesh. Fine. You do you.
Obviously I can't know for a fact. I also thought they likely analyze photos and that's my chief suspect even now. But critical thinking demands to keep an open mind -- and that's how I suspect they might use fully-charged iDevices (that are expected to sit on the charger for several more hours) for unsolicited and non-advertised P2P computations.
I don't claim it, I merely suspect it.
