I have the extended battery, since the last updated I could get about 3 days use! Yes, I'm a very light user & have crazy settings toward this goal.
In the last couple weeks I've been lucky to get 40 hrs out of a battery & I blame it on the dialer. Right now dialer is #2 on the use list taking up 28% of the last 1d 2h battery since taken off the charger. Odd thing is I haven't used the for over 3 days, no incoming or outgoing calls.
I know, I should be happy with 40 hrs, whatever - I manage the phone to get my time. It's one thing to have the cell standby or phone idle or whatever has to run in the back ground using up battery. It's another to have an unused service eating it up like a fat kid at a buffet. grr.
