Yes, all electronic cables—especially charging and data cables—undergo both physical and chemical degradation. Physically, the internal copper or fiber-optic strands experience "mechanical fatigue" every time the cable is bent or coiled, eventually leading to microscopic fractures that increase resistance and slow down charging speeds. Chemically, the plastic or TPE sheathing can become brittle and crack due to UV exposure or "plasticizer migration," especially in cheap, unbranded cables. In 2026, with the high power demands of 100W+ USB-C charging, a degraded cable isn't just slow; it's a fire hazard. If you notice a cable feels unusually warm, has visible "fraying" near the connector, or requires "wiggling" to start a charge, it has reached the end of its safe lifespan and should be replaced immediately to protect your device's battery and circuitry.
