I was also experiencing a sudden quick battery drain after the upgrade to .148. I followed this problem in a couple discussion threads. Seems pretty random, some have the problem and others didn't. This was a very real problem on my phone. Reading all the other threads, the pattern seemed to be around a few apps. I removed the follow apps and the battery life is back to normal:
Weatherbug (I believe this is the main culprit)
Vcast
Poynt

My battery was draining fully after only 8 hours, and now it's been 12 hours and I'm still at 80% charge. Other then this battery issue, the .148 upgrade has been a big improvement on my phone.

Thanks to all for the helpful analysis and problem solving!
