This is an issue with the configuration on that particular WiFi network and not an architectural issue with IPv6.

But these measurements were during active use. https://tools.ietf.org/html/draft-petrescu-v6ops-ipv6-power-ipv4-00 Cloudfare’s view: "That means that a v6-only mobile phone (looking at you, T-Mobile users) can establish a clean path to any site or mobile app behind Cloudflare instead of doing an expensive 464XLAT protocol translation as part of the connection (shaving milliseconds and conserving very precious battery life)." https://blog.cloudflare.com/always-on-ipv6/ https://blog.wirelessmoves.com/2008/03/why-ipv6-will-b.html Check out the slide titled “IPv6 brings savings in battery life” about 8 minutes into the video. https://www.youtube.com/watch?v=o5RbyK0m5OY Another RFC for network administrators. https://tools.ietf.org/html/rfc7772 So if you find that a specific WiFi network accelerates battery drain send some of the info mentioned in this thread to your local WiFi network administrators but don’t tell the world to turn off IPv6. > On Oct 6, 2017, at 7:32 AM, Mike King <m...@mpking.com> wrote: > > So I saw this on Reddit this morning.
