Dude, I've got the same issue when I updated my phone to 8.0 GDR3 preview about half a year ago. I was even wondering if it was a problem for products from specific distributors (mine was purchased in China, kind of a local type called 920T, modified by the stupid network operator here).
I tried everything just as you did, and at last my rescue was to first roll back to GDR2, by using Nokia Software Updater for Retail, which did not solve the battery draining problem, but get my warranty and every information needed back; then I go to a Nokia service department, asked them to re-flash my 920T to factory defaults. That's when everything became normal again. It did not take long, each rolling back may take 10mins to 30mins perhaps.
When GDR3 was officially pushed out, I accepted it with full preparation of having a same issue and having to roll back again, but to my relieve it turned out to be just fine.
This time I became clever by holding back my curiosity and waiting patiently for a public official release. It's just why the battery issue appears to a certain number of products confuses me.
Anyway I hope this might be of any help, and may you get your system back to normal again very soon.
