We do do quantitative > battery drain studies, and the ipv6-off configuration is meaningful better. Is this with or without IPv6 configured (thus, RAs) on the home gateway ? I'm keeping my fingers crossed that this could be one of the cases where the WiFi chipset is IPv4-smart and IPv6-unsmart, therefore requiring the CPU for anything IPv6 related.. Did you have a chance to further narrow down the root cause of this ? --a
