Exchange Activesync is working great, but I'm down to 40% battery after about 5 hours (it was down about 10% when I did the install five hours ago). Only a few phone calls and total of 10-15 minutes with Texas Hold'em and NYT software. Granted this is iPhone I and the "unofficial" downloaded 2.0, but that is a bit on the scary side.
What are others seeing?
I'm seeing the same rapid battery drain here. The previous beta build did not exhibit this issue. I'm starting to hope this isn't the final release.
