Hi Med,
No, it was not an IETF document, it was another study. I can't find anymore a link where it was published ...

Hi Jordi, all,
I guess you are referring to the study that was echoed in RFC7849:
==
According to [Power], the consumption of a cellular
device with a keep-alive interval equal to 20 seconds
(which is the default value in [RFC3948], for example)
is 29 mA (2G) / 34 mA (3G). This consumption is reduced
to 16 mA (2G) / 24 mA (3G) when the interval is
increased to 40 seconds, to 9.1 mA (2G) / 16 mA (3G) if
the interval is equal to 150 seconds, and to 7.3 mA (2G)
/ 14 mA (3G) if the interval is equal to 180 seconds.
When no keep-alive is issued, the consumption would be
5.2 mA (2G) / 6.1 mA (3G). The impact of keepalive
messages would be more severe if multiple applications
are issuing those messages (e.g., SIP, IPsec, etc.).
==
That’s said, and as usual, we need to be careful in extrapolating results.
Cheers,
Med
