I don't have much to offer this thread yet from a technical solution perspective, but i can share that Samsung and others deactivate ipv6 when the smartphone screen is off due to battery issues with ipv6 and wifi. This is not for anyone to judge, this is a problem statement and the current solution deployed on 10s (100s) of millions of hosts that go from dual-stack to single stack when the screen is off. We do do quantitative battery drain studies, and the ipv6-off configuration is meaningful better. These phones do a fair amount of background traffic to major ipv6 enabled clouds (google , facebook, yahoo ...) when the screen is of, so that is an ipv6 opportunity missed ... we need a better solution to take to the smartphone oems so they can keep ipv6 on and still meet the battery drain targets. We already know home routers dont get upgraded ever, so a client based solution would be nice. Said another way, i can help drive deployment of a client based solution. CB
