After only using for ONE day I did not have very good results. Of course when I received it yesterday I did not fully charge it as I should have until yesterday afternoon. Last night I used it quite frequently (emails, BB Chat) and accidently left the Bluetooth on. This morning it was at 21% and this was leaving it in the holster overnight. I will fully charge it today and report back to see if it improves.
It also may be a factor that I have a poor signal at my house. If only Cingular would do something about that I would be golden. I have no issue with Verizon working at my home.
