Over the past two full days of use...
Taking it off of the charger at 9am... with about 1.5hrs of talk... ~40 emails... around 30min total of web browsing... ~10 text messages... by midnight or 1am... it's still got 4 out of the 5 battery bars. Going to Options/status shows battery no lower than 70%.
I'd say that's fantastic for a CDMA device.
Blows my Q away.
