never seen this before. battery lost 46% in 45 minutes

[UTnick]

alright, took my phone off the charger at 8:22 am when i woke up this morning and didn't touch it. not a single thing. after getting ready and leaving for work at 9:09 i turned the screen on to turn on Bluetooth to call someone. that is when i noticed my battery was at 54%. Whaaaaa? 4g wasn't on. the phone wasn't hot. i have not idea what was running in the background, but i am gonna put up my appbrain list if anyone wants to take a look at it.

and i plugged the phone in before i looked at the battery history. bah.
