If the battery is the same charge and power... I don't see how anyone here thinks the iphone 5 will last as long as the 4.
Wow. So many things you're so sure of, even though you're wrong.
Faster processor no matter how efficient, will run the battery down faster. a 1.5 hrz processor will always use more power than a .4 hrz processor.
Faster processor = more power hungry? This is only true when you're comparing the same processor design on the same process. There are *many* factors which effect the efficiency of the chip. The primary two are transistor count and process size.
Yes, within the same processor generation, the faster = more power hungry rule applies, but once you change processor generations or fabrication processes it does not.
If only we had a processor family change in recent history to use as an example (like say the P4 to Core Duo) to disprove this claim.
The screen is bigger thus more light thus more power.
The screen's (rumored) technology is also thinner, and passes more of the backlighting through to the user. This means greater efficiency because it uses *less* light to get the same effective brightness.
This will probably be a net battery life *gain*, despite the larger screen.
LTE... if it the was for 3g.. will drain the battery faster as well.
There's a reason Apple waited for the current generation of LTE chipset. The first generation was miserable for power consumption, *and* still required a 3G chipset as well, making matters worse.
The LTE chipset rumored to be used in the iPhone 5 uses a more efficient (smaller) process, and includes LTE (worldwide), GSM, and CDMA all on the same chip. This means the phone will only need to power a single chip.
This is probably a wash on battery life, but will be heavily dependent upon signal quality in any given area.
The iphone 5 will still be great compared to the competition, but we all have to be pretty oblivious to expect the same battery life as the iphone 4 with the same battery.
Odds are, the announcement of the iPhone 5 will include a statement to the effect of, "all these great features, and still the same battery life", or maybe even a small improvement.

Oh god
Just stop it
So if we don't like something we should shut up?
No, not necessarily. On the other hand, if complaining about it isn't actually going to have any effect, what's the point of wasting your energy?
