iPhone 4S Battery Life

Has anyone encountered the battery life problem with their iPhone 4S?  I've seen a few articles and heard a few anecdotal reports, but I'm curious what The Verge users have found.  I was considering a 4S as my next mobile device purchase, but the battery woes give me pause.  It seems likely to be a software bug based on the little information I have found, which means perhaps a simple patch may resolve the problem rather than a more costly hardware problem.
