Summary
This video explains the black marks that appear on Apple Lightning cables. It clarifies that these marks are not a sign of the cable being worthless, but rather a result of the gold-plated contacts oxidizing over time due to wear, tear, electrical arcs, and corrosion. The creator advises keeping the pins clean to prolong the cable's lifespan.
