iPhone17 Pro氧化问题越来越严重，苹果正调查原因

Core Viewpoint - Apple is reportedly recalling iPhone 17 Pro and iPhone 17 Pro Max devices due to a color fading issue, which is believed to be a limited manufacturing defect rather than a widespread problem [1][9]. Group 1: Issue Overview - Users have reported color changes in their iPhone 17 Pro and Pro Max, particularly in the "Starry Orange" color, leading to significant attention on social media [1]. - The fading issue has been observed mainly at the edges and around the camera bump, while the back panel with the Apple logo remains largely unchanged [1]. - Some users have also noted similar fading in the deep blue version of the iPhone 17 Pro, although the color difference is less pronounced [3]. Group 2: Technical Analysis - Apple has advised against using bleach or hydrogen peroxide for cleaning the iPhone 17 Pro, suggesting that exposure to such substances or prolonged UV light may contribute to the discoloration [7]. - Analysts suggest that the issue may stem from the aluminum alloy used in the iPhone 17 Pro, which is less corrosion-resistant than the titanium alloy used in previous models, making it more susceptible to oxidation [7]. - The anodization process, which is intended to protect the aluminum, may not have been properly sealed during production, allowing the aluminum to oxidize and change color [8]. Group 3: Company Response - As of now, Apple has not officially responded to the reports of color fading, but users have indicated that Apple is providing replacement services for affected devices [9].
