About a week ago, in preparing to run some errands, I plugged my iPhone 4S into the charger in my car so that I could stream Pandora while I drove. Oddly, a “this accessory may not be supported” message appeared on-screen; when I unplugged and re-plugged the iPhone to the charger, it didn’t reappear, so I didn’t think anything more of it … until a half hour later, when the iPhone again alerted me, this time with a “low battery” message. For some reason, attempting to charge the battery was instead rapidly drainingit; unplugging the phone from the charger restored the normal discharge-via-use rate. But by that point, the “damage had been done;” none of the chargers I tried would restore normal operation, and the battery was soon completely drained.
