I hope you understand that adding more features equals more processing power to be used, equals higher power draw, equals worse battery life.
Add more features that enables you to use more content online and here you go. It all does cost you more CPU cycles...
Obviously, every comment that points to a possible Apple's fault on worse battery life will be taken as if it was an attack on Apple and/or some of the users of this board. I did not mean to attack you or anyone here, I just said you and others should consider a few more things than simply saying "runaway applications are the issue" + posting a link <-- this seems pretty much like saying: Apple good, your_3rd_party_application bad.
I am not 100% happy with battery life but cannot complain either. Also, this thread has plenty of reports saying that even clean installation did not solve the battery life - this has to be considered as well.
@CSound1: what is so strangely enough that happened with me? Where exactly did I say that I discourage others from investigating their issue?
