Not on my first gen though, still could last me the whole day.
I'm on Gen 0. I ended up hard resetting and restoring with a recent backup. Experienced the same issue. Hard reset again and used an older OS 3.x backup - it worked! I'm back to the same battery life as before, which is last the entire day and end up with about 30% by 11PM.
Something is buggy about either OS4 or OS4 related app/watch faces. The only thing I did recently was use the Siri watch face. When I noticed the battery drain issue, I figured it's because of how often it must update the various cards available. Even after removing the Siri watchface didn't resolve the battery drain - only the old pre OS4 backup did the trick.
Weird.
