IPhone 5 battery life review?

How good is the battery on the iPhone 5, last years model?
I'm getting the 5S which will be improved because of the lower power consuming processor, and the larger physical battery. But on average how well was the iPhone 5 battery? Better than the iPhone 4S? How many hours of mixed usage on average?

Can I transfer my iPhone to a prepaid? If so, how?

Ok. So I have an iPhone, and my mom got really upset with AT&T and all the surprise extra charges and stuff, so she just ended up canceling the whole thing. We all had iPhones except for my mom, my mom got a galaxy SIII, so the rest of us got the iPhone 4 (except my dad, he got the 4s) and my mom ended up finding a way to switcher her galaxy SIII to prepaid with straight talk, so now she doesn't worry about all the expensive bills and so on… The rest of us however, got switched to prepaid and ended up with these cheap little prepaids that practactly do nothing. And she said if it was possible, we could switch our iPhones over if we wanted. So the other day I went online to just search some of this out. All the prepaid plans I looked at, have the iPhone4 displayed for sale at like over $400 dollars! So I already have an iPhone, so rather than paying for a whole other phone, can I just switch over this one I have now? What are some good company's?

I'm planning on ordering it on the 20th early in the morning (I mean like 2:01 because I live central). How long should it take for me to get it? I should be one of the first ones to order it, but do any of you have an estimate? Thanks…
P.S. - I'm hoping I will get it by at least the 27…
