have the Razr, have the same issue.. sorta. Kind of reminds me of my old TBolt days - 20 mins off charger without doing anything, and I was already down to 85-90%.
I did a full reset of mine, didn't reload anything right away, and saw no real improvement in battery life. I have noticed that the screen % in battery usage is ridiculously high all the time - I'm talking 60+% on the regular, when before ICS it was down in the 20s... and the settings are exactly the same.
Sounds similar to what I've been experiencing. Phone off charger for 30-40 minutes, no matter what I'm doing with it, and it's down to 90%.
