Any one else having the same issue please report.

I took it off the charger yesterday morning and with a couple dozen texts and ten calls I'm at 55% right now (36 hours later). Just turned on Slacker over the Phone Speaker so I'll post up with my batt life in a bit.
Followup- Since my last device was a Treo 700w, I didn't have the variety of stuff to check out or connectivity options as the Pro2.

So now that my feet are wet, I thought I'd share the results about what I learned. Asking this question prompted me to do some easy tests.

I ran 15 mins of Slacker over Wifi with a couple of texts - 4% drain. Then ran another 30 mins of slacker with nothing else - 5% drain. So, roughly 10% per hour.

Then I ran an hour of Slacker over Ev with nothing else and it used over 30% in 1hr

The number may have been skewed a bit since the battery hasn't been cycled through, I'm thinking that sucker dropped pretty fast after it got under 15%.

And some discharge readings, just for fun.

Idle (Screen 50%) - 135mA (range is 80 to 130)
Idle (screen Dim) - 70mA (range is 35 to 70)
Idle with WiFi active - 300mA
Idle with 3G - 375mA
Slacker Wifi with speaker - 350mA
Slacker 3G with speaker - 425mA

I've dropped a bunch of cabs on this ROM and it's still solid with tons of battery life. The WiFi/3G just burn it up, that's all.
