Anyone notice higher power consumption on 2.2.0.29 on Xperia X?

Normally it takes a few days to settle (reindexing and whatnot) after an update, and the battery is back to normal. But this time it doesn't seem to last anywhere near as long as before.

I may reflash and see if it fixes it, but right now it's not looking good. I'd kill for a custom kernel that I could undervolt with...
