All, I'm currently using Touchdown for my exchange work email and works great. But I'm currently trying to figure out what is sucking my battery life from my device..i'm getting close to 11hrs if I'm lucky but more like 9/10hrs on normal use. No facebook sync just gmail, touchdown, weather. Brightness at auto. I'm trying to eliminate the obvious and thinking Touchdown might be a battery sucker and hoping the default exchange email app might be better. What do you think?
