Last time I did a battery drain I did on the IP5 on iOS 6.1.4, I got 7 hours and 57 minutes of usage and 11 hours of standby. My IP5 is the first batch from launch day.
I'll screenshot it for you guys in the next couple of days.
EDIT:
Might as well screenshot something to give you an idea, these stats wouldn't be possible if the useage state above was bogus.
