You are so lucky I was at 80% after 2 hours of use. I am not sure what is going on with my phone I did the update and then did the FDR yesterday but the battery is still not giving me the type of length that you are experiencing.Not sure what I need to do to make it better.
Things I have done: Set screen brightness to auto and checked battery saver. Set weather sync to 6 hours. Killed the facebook process ( a big battery hog). Set my pictures to auto upload only on wifi when plugged in. I also turned off the feature in "gallery" to see others pictures (another big battery hog).
Once a week I let it drain down to about 30%, turn it off and let it charge overnight. The rest of the time I charge it with it turned on - about every other day now.
Funny thing though is I've thought from the start I got a "good" phone because I really haven't had a lot of the other problems I've seen posted on the forums.
Did a lot of the same things on my wife's Samsung Stratosphere and she sees similar results, as opposed to our son who won't let me tinker with his phone and has to charge twice a day.
What all did you do to save your battery life, or is it just what you listed here??

Can you describe what you mean by "checking battery saver", "killed the Facebook process", and what Gallery feature are you referring to about seeing other pictures?
In Screen settings under brightness, there is a check box for "Display Battery Savings" that I checked.
For gallery, I had unchecked "Display Friends Pictures" (or something like that) but apparently that setting is no longer present in JellyBean.
To kill facebook, I go into running apps under manage apps and stop all the FB processes. I don't use FB that much on my phone so I may actually disable the process alltogether.
