The yellowing of an iPhone 15 case cover is a predictable chemical process, not a manufacturing flaw, and understanding why it happens can help you keep the Zapvi phone case crystal clear for the long haul. Heat accelerates the change, so leaving the iPhone 15 case cover on a car dashboard or wireless charger for extended periods can cut the whitening timeline in half. Prevention starts with material choice and routine care. The Zapvi iPhone 15 Plus back cover is blended with UV-blocking additives that absorb harmful wavelengths before they reach the polymer backbone, slowing discoloration by up to 70 % compared to standard clear shells. When the phone is not in use, store the iPhone 15 Pro back cover away from direct sunlight; a drawer or a pouch blocks both UV and ozone, the two primary drivers of yellowing. Eventually every clear iPhone 15 Pro Max back cover from Zapvi will reach a saturation point; when the hue no longer responds to cleaning, replacing the shell restores showroom clarity and ensures the shock-absorbing properties remain intact.

Zapvi offers fresh replacements to maintain that pristine look.
