I had forgotten about this thread. I did end up tracking down the real cause of the wifi drain issues I was having, and I'll get to that in a minute.
Battery drain after video call, sounds like the camera daemon bug that 4.4.3 was *supposed* to fix. Have you posted a BBS log for investigation? I did not see one while quickly skimming over the thread. But if you are not on 4.4.3, I would suggest migrating over at your earliest convenience.
Now, to fix the wifi related battery drains is simple. Delete these two directories and reboot: /data/misc/dhcp, /data/misc/wifi
This will also reset all remembered networks.
