I really wish the article explicitly explained exactly what happens when you manually manage the multitasking bar. My anecdotal experience is that removing an app from "recently used" does have the effect of terminating it if it was in one of the semi-background states. While the advice to manually manage this is ham-fisted troubleshooting, it is unfortunately effective (cf. restarting Windows). I suspect (and would love to see more analysis on this) that some apps in the categories allowed infinite background time are behaving badly. It may only be one VOIP app running persistently in the background that drains the battery, but this advice would consequently solve that problem.
