And thank you Bpowder....! If this does not work I will try ultimate.
I had the same issue, except mine was trying to update multiple times a day even when I tried to defer the update. It also removed root access, so I ended up having to reroot using Amon ra, then buy Ultimate Backup to freeze htcdm and htcCOTA. So far so good, thanks for the suggestion I was getting very frustrated with having my battery drained and needing to reboot every morning.
