I am starting to think something may be wrong with mine, I recently got a Blackberry for work (dilemma, I know!) so have been using my iphone far less (wish it wasnt the case but restricted by email server!!) and still getting fairly poor result from my battery despite limited use.
I have to charge each night and often do not even have 1 hour usage..
Will be taking note tonight as to my official Usage and Standby time from the Usage option in settings - this is by far the most accurate method of comparison.
Also to note, this includes WiFi off, BT off, autodim on etc etc...
What sort of time frame and usage do you get??
