Mine and my wife's both seem to be draining the battery faster. Not sure if there are apps running in the background or the phone is updating more frequently. It is also due to the fact that we are using them a little more setting up and using the new apps. Both phones are also slower to react and type on and freeze occasionally. I see a 2.1 revision coming soon to get some of the bugs out, or could just be Apples way of moving us V1 holdouts into the next generation
