Old Exchange Flaw Persists in iOS 7

A series of symptoms that often arrive hand in hand, sporadically, on Apple devices running various revisions of iOS 4, 5 and 6, up through 6.1.3.  Those symptoms include devices running warm to the touch or even hot, a battery that may drain significantly faster than normal, and spikes in cellular data use of up to ten times the user’s normal pattern.  While this trio of symptoms may well have more than one culprit, the many instances that I’ve personally witnessed have since been reduced to a single common cause.  One with a quick solution.
