after the first day or two i wasn't use to it and thought it was bad, but today it held up VERY well. Then again after a forum member suggested juice defender i have been seeing some good improvements.
I got to do very moderate usage, browse google reader (200+ new articles) send out more than 20+ emails and sms, downloaded around 10 apps, just literally play around with the phone see where everything is.
i have it set to the lowest brightness which is fine for me, i didn't charge it since tuesday night and by wednesday afternoon about 4:30pm it was around 70% which is fairly good. After that time i did some heavy usage and it dropped to 15% by midnight.
All in all I take back what i said about it, it's actually pretty good.
