Would the electrical noise damage the battery in the long run?
I've always been leery about plugging my iPhone into cheap 3rd-party chargers, but I never knew if the logic behind my fear was sound.

The circuits in the phone may be damaged by excessive spikes. Especially if the spikes happen to be of a frequency that the internal filters / regulators in the phone aren't good at rejecting -- some regulators may only reject 20 dB of noise in certain bands, and > 80 dB in others.
