been doing a lot of tweaking and experimenting over the past 13 days and i am now at 16 hours with 40% of battery left...did one battery condition cycle on the first day...i had juice defender and smart actions running at the same time and that was just not working....jd seemed to confuse the sa so i removed it and am now running just sa...i also switched my work email to update at 5 mins instead of push...no widgets at all that need updating except beautiful widgets for my home screen but that updates when the screen comes on....i am now going to try sydman's advice and turn off the bg sync and cell data while the screen is off...that should save me a bunch more...also..it is am switching between 4g...3g.. and wifi a lot depending on where i am..
