A piece in TechRadar says:
Devices that use IPv4 to connect to the internet use less power than
gadgets running on IPv6. A report by the Internet Engineering Task
Force (IETF) has found, by comparing identical smartphones running on
IPv4 and IPv6 respectively, that IPv6 requires roughly 5% more power
to run. 5% may seem like a small amount, but when multiplied by a
billion or two, that number becomes a significant energy expenditure.
It then goes on to say that the solution is to forget IPv6 and instead
lease IPv4 addresses. By an astonishing coincidence, the author is a guy
who leases IPv4 addresses.

You do not have to tell me this is nonsense, the IETF doesn't produce
reports, and certainly not reports about phone power consumption (so
please don't.) But does anyone have any idea what this "report' might be?
R's,

The main thing that comes to mind when I think of "IPv6" and "power consumption" is RFC 7772, "Reducing Energy Consumption of Router Advertisements" (but there's zero mention of IPv4 in there).
