I don't think nat64d should be using a significant amount of CPU time. You can check this by running:

cut -d" " -f14-17 /proc/`pgrep nat64d`/stat

This will show four numbers: User CPU, System CPU, Child Process User CPU, and Child Process System CPU. They are in units of 1/100th of a second.

You can also check to see how much traffic has gone through the nat64 process with:

/sbin/ifconfig nat64

I haven't personally noticed any difference in battery usage, but I'll have to compare a day's usage on ipv6 vs ipv4 in battery-eye.
