What could cause the sharp drop in battery life for my iPhone 4S? Even if fully charged, it will deplete within 5-6 hours of idle time.

I noticed this problem about ten days ago when my iPhone did not wake me up. The experiment repeated the next evening, with a fully charged battery, resulted in a drained phone the following morning.
I have made no changes to the phone that correlate with the suddent drop in battery life. I have been running iOS 5.1.1 since last May (jailbroken). I've restarted, resprung, and made every effort to ensure that no battery-draining apps are running in the background. No success. Extensive Googling has yielded no solution.
I suspect that this is probably an issue with the battery itself that will require replacement of the phone. However, I am interested to learn if there are any last-ditch efforts I can take before I need to talk with the geniuses.
Thank you very much.
