My understanding is that Oreo is even more aggressive with doing things
to save battery than Nougat did.  Mine is on Oreo and is obviously
going into network silence (except for push traffic), but I don't know
if that is standard Oreo or my phone manufacturer being even more
aggressive than standard Oreo.  It would be interesting to see if your
experiments work equally well on a standard Oreo phone.

That's impressive.

I wouldn't disagree, in the case where the phone remains on the network
the whole time it's sleeping.  Mine doesn't.  I wouldn't be surprised
if mine isn't the only one doing that and that more and more will be
doing so in the future.
