I too tried the SMS fix, no luck… still running at 100%.

Then I reset my Hero to factory defaults and tried the SMS fix again. That worked until I setup my Exchange Account in the built in Email client (NOT Gmail client). So it is the built in Email client that causes the phone to stay awake 100% of the time too.

Therefore, I reset my Hero again... Installed HandCent to fix the SMS issue. I then installed the TouchDown trial (5 days only) and setup my Exchange account and all is working well. My phone now reports between 30% and 40% awake, which is tons better than 100%. However, I still haven't made it thru a typical 16 hour day without having to charge the phone on the ride home from work. But at least I am not having to charge it at work any more. Part of the problem for me, might be that I get terrible reception in my office so the phone frequently switches between the Sprint netowrk and roaming.

Finally, I have noticed that the awake time percent will creep up around 80%+ from time to time, but a power cycle fixes that. So I am pretty sure that there is yet another app causing the phone to stay awake. If I find it, I will post my discovery or at least try to update this post. If I can figure out how to do that. ;-)

Hope this info helps someone!
