Nah, don't have any third party battery app installed. Don't even have any battery tests running from BDA. Plus, this has never been the case with any previous OS. And it's only on 3G. Phone stays on for about 15-20 minutes on EDGE.
I know 3G takes up more battery. Reason for posting was because on no previous OS would it shut down that quick. Even on 3G only or even 3G plus 2G it would stay on for 15-20 minutes.
