Just picked up my tbolt today and..

Maybe 4 hours of constant use with the screen on full brightness. But most other phones will die in that time also. Think I got about 4.5 from full to the point that it turned off on my Fascinate while watching various shows on the tv.com app trying to see how fast it would die.
 
It's funny but I notice only a small difference whether the kickstand is out or not.

im looking in the market and see an app called z-devicetest, it says it will check the health of things on your phone. wonder if you try that if it will tell you if you have a bad speaker or not.
 
does it still sound low with the kickstand out?

yeah. little difference with kickstand out or in. I'm not saying its not loud. just saying that its not louder then my incredible. which i don't understand because the speaker on the bolt is bigger and better? lol
