You mean people who posted to the thread with 2 million views have forgetten how to post? Or perhaps they don't have a problem. Which would mean the problem is not huge at all.
There is a constant stream of "battery problem" posts that has been going on as long as there have been iPhones. The number for 6.1.3 is small compared to other versions, and even compared to battery reports between updates. And you will note that many of the posts in this thread say that 6.1.3 FIXED the battery drain problem in 6.1.2.
I'll say it again, as I (and others) have already posted. This is NOT a problem specifically with 6.1.3; it is a side effect of updating with apps running. It will happen to a few phones after every update. And it will happen to a few phones between updates. And Apple will never release a fix for it, because it isn't an iOS problem, it is an app problem, usually a problem caused by bad data in an app.
The bottom line is you either live with it forever, or you troubleshoot it yourself and fix it. Or you continue posting how huge a problem it is, instead of spending that time troubleshooting. It may make you feel better to complain or invoke Steve Jobs, but it won't resolve your problem.
BTW, posts about battery drain were just as common when SJ was alive.
