I believe the batteries are the original 1340mah ones.
The battery icon will say it's 100% after charge. Pull it from the charger and within maybe 15mins it will drop to 90% with no usage. Then with various usage (texting, maybe a call or two, checking movies times, etc) it will drop down to 40% or so.

I tried my normal usage, calls, texting, streaming slacker in the car, browsing the internet which does drain the battery but I've never had to charge the phone 3 times in one day.

One thing I did notice that seemed odd. After I synced the phone with activesync for the first time it kept kicking off activesync on the phone like every 10 or so mins. This behavior did not happen until after the first successful sync. It was repeatable for me as well.
