running 14 hours with about 3 hours of awake time at 19% now- did this on off charge 2ce - along with some sync disabling and installed Advanced Task Killer to Kill aggressively things that i do not use like the sprint software and voice dialer but setup things i always use in the "ignore" list so that it wouldnt kill those things.

before i installed Launcher pro - i got over 24hrs even with the Htc weather animation on the home screen.

things i synced every 2 hours were
google gmail mail and nothing else
facebook contacts and unchecked live feed
weather

i too on my first few days had around 4 hours of battery time with light use - text mostly and app instals with some camera pics.
i first didnt want to install the task killer - BUT AFTER i did all the disabling of the live sync stuff my battery still didnt have the 10 hour use like others did.. after i installed the tasK killer and set it up to kill apps i do not run nor that i thought were somehow linked to eachother - i got over 24hours plus on a charge while sending out lots of text - watching HD you-tube surfing numerous websites downloading apps configuring my pages - all at about 8 hours of awake time.
