After dealing with short battery life like many of you, sometimes only getting 4 hours after a full nights charging and the phone just sitting on my desk,i figured out how to make it go the full day, even with regular use of web and email/sms. For me, it was simply reducing the frequency of syncs between all the various social networks I'm part of. My setting used to be every hour for Facebook, Twitter, and the worst culprit, Flickr. i would notice the phone constantly getting warm to the touch even if it just laid on the desk. Since changing the frequency to manual refresh, my battery is still well over 60% by nights end. YMMV.
