Problem with quick battery drawing

Hi,

I had a hybrid OS installed on my Bold 9700 for nearly a month now. Yesterday I pulled my phone from the charger (phone was completely charged) and in the evening, about 14 hours since I unpluged it I noticed that I had only 20% of the battery left. Just a day before that my battery could easily "survive" 3-5 days of usage. I pulled the battery from the phone and charged the phone through the night, unpluged it today and now (3 hours later) 25% of my battery is gone and I only wrote like 10 text messages.

What could be causing this sudden battery "leaking"? I haven't installed any new applications or anything.

What were you doing in those 14 hours?

I wrote and send about 30 text messages and that was about it. I usually write about 30 text messages, make about 5 minute of calls everyday and still managed to easily get 4 days out of it.
