I installed this update yesterday afternoon. I had no real issues then or overnight, but first thing this morning, I was seeing a fast drain on my battery. In the first hour after unplugging it, I was already down 11-12%. I decided to perform a "Reset Network Settings" and then restart my iPhone, and after fully charging it, I was about an hour and 10 minutes unplugged and still showing 99% battery remaining. Since then, I've been unplugged 10.5-11 hours with 4.25 hours of that being "screen on/usage", and I still show 68% battery remaining.
I do sync email, calendars, and contacts to a corporate Exchange server with my iPhone 5 as well. To be honest, I am getting a little betttery battery life with this update than I was getting before I applied the update. One last note, I installed this update OTA, rather than trying to download 970+ MB from the Apple servers through iTunes. The OTA update was 12.5-12.8MB for me...
