The lifting it up thing is interesting. I wonder if that's done with an
accelerometer? If so, it would be checking that too.

A few more comments, but I don't know much about this topic.

1. Even if a phone is "off", when you plug in a charger, "something
   happens", so is it really off? I don't know, but how does it charge?

2. The government has, in the past, secretly modified gangster's phones
   such that they looked to be off, but were secretly still transmitting.

3. The iPhone, I believe, is never off, which, I'm told, is how the FindMy
   sensing works for stolen phones.

How does any of that work? I don't know.
