Drag the CAB from the link in the post below yours onto your phone and install it (
*keep your phone plugged in and ActiveSync up and running on both PC and Touch Pro throughout this process*). After you've installed the CAB, go to Settings>System>Task Manager on the phone and you'll see 'ActiveSync' running in the Programs List. Pull out your stylus and hold it on 'ActiveSync', after a second or two it'll give you an option to "Add to Exclusive", select that. After THAT, go to..
HKEY_Current_User/Software/Microsoft/ActiveSync
..using your favorite registry editor and change "Resilience" from 2 to 0.
NOW unplug your phone from your computer and soft reset. When it boots up, go into any custom Task Manager program (
this one is the best in existence) and kill "repllog.exe". FINALLY, from here until your next soft reset or synchronization with your computer, you are ActiveSync free and will see at LEAST a 20% gain in battery life. I've gotten ~40% more use with this fix, and that's not a joke. ActiveSync just eats away at RAM & battery is painfully inefficient.
Enjoy, and feel free to post or PM any questions!
