Battery is toast?!?

[avhokie]

I spent last week in Europe. I had my Sprint Diamond with me. It doesn't work there of course, but I turned off all of the communications (phone, data, bluetooth, etc) and kept the phone on just for meeting reminders and alarms. It lasted 6 days and still had 80% or more power.

However, since returning it has died a quick death each day. Today, with bluetooth off, no programs running, 30 minutes of talk time, no text or surfing, it went from full charge to dead in 6 hours! I'm using a Juicy ROM and battery life has been great. What gives? Do I have to get a new battery now?!?
