I saw several people mention this in the 1.2 thread, but haven't seen any kind of conclusive decision.

I noticed that after updating to v1.2 firmware I can no longer make it all the way through my work day. This is a very consistent finding now having used the firmware since the first day it was released. I have the Seido extended battery (though not the really big one) and was able to get through my work day 95%+ of the time but now it just doesn't happen.

I haven't changed my usage at all with the new firmware.
