According to posts on Reddit, X (Twitter), and Apple Community forums, the problem seems to appear mainly on devices without cases, though a few users have claimed the discoloration occurred even with protective covers. The fading reportedly starts near the edges and gradually spreads across the titanium back panel.

Some users speculate that the titanium coating or anodization process used in the orange variant may be reacting to sunlight, skin oils, or humidity. Others believe it could be a manufacturing defect in the color layer applied to the titanium frame.

Apple has not yet released an official statement regarding the issue. However, several affected users claim they have received free replacements or repairs at Apple Stores, suggesting the company might be quietly addressing the problem.

The iPhone 17 Pro, launched in September 2025, introduced new color options including Titanium Orange, Blue Mist, Natural, and Graphite Black. The orange edition quickly became one of the most popular choices due to its vibrant finish and premium look — making the color-fade issue particularly disappointing for early adopters.

Tech experts advise users to avoid direct sunlight exposure and use a case until Apple confirms whether this is a surface reaction or a deeper coating issue.
