Ok not so much but I used to have this very annoying issue with my old storm where i would set my alarm for lets say 7am and go to sleep with a full charge and wake up the next day with no alarm and find my phone turned off because the battery fully drained over night. Since i have had the TB this has happened to me twice, this morning being the latest incident. I had no new apps running before i went to sleep, just the usual and still the phone completely drained. I actually was a bit impressed before this happened because for about 2 days my battery had shown great improvement as far as battery life and then this happened. I love this phone but this is getting very annoying.
