This update address the battery in no way whatsoever. If you are seeing better battery life something corrupted was overwritten or its in your head.
I got better battery life today (post update) then I did yesterday (pre update). I'd hardly consider that a very conclusive test.
6.1.2 didn't really introduce battery issues in general. Yes some people ran into battery issues as it happens with a lot of upgrades with at least some people but the overall majority didn't experience battery issues with 6.1.2. For various different reasons there will always be people with battery issues with pretty much any version of iOS and any iPhone, sometimes there are more of those people and sometimes less--and sometimes it is the particular iOS version that is at fault while quite a few other times it's something else (and often enough simply resetting settings or reinstalling the OS can get rid of those issues, which is why often people might see improvements after a new update simply due to a new installation if they were seeing issues before).Woo hooray! you got a perfect iPhone! Believe me, 6.1.2 screwed up my battery Royally. Please don't comment if you don't know anything about what you're talking about.
