Abstract:
Many of the first batch of users who bought the red version of the iPhone 18 Pro recently discovered a terrible problem. Many people couldn't help but ask online whether the new iPhone in their hands has faded. Recently, a large number of users who have purchased the red version of the iPhone 18 Pro have complained on social platforms. They bluntly said that the body of the new phone has oxidized and faded after just a short time of use, which directly compromised the bright texture when it was first purchased.
Judging from the actual pictures posted by netizens, the fading situation this time is quite serious. Users have previously posted feedback that the body color of the burgundy red iPhone 18 Pro lens module has become significantly lighter. Even with the black version, many users have reported similar local discoloration problems.
It is worth noting that the previous generation iPhone 17 Pro series has already exposed the same fading problem.
The Xingyu orange color model was most affected at that time. The originally bright orange casing gradually turned pink and discolored with daily use. Related problem cases concentrated on specific production batches, and not all models were affected.
Many users who have been affected by the scam have reported that they wear protective cases for their phones all day long and have never wiped the phone with chemical cleaners such as alcohol, but they still have discoloration without warning.
Practitioners related to industry processes pointed out that the iPhone 17 Pro series uses an aviation aluminum alloy middle frame for the first time, relying on an anodizing process to color the metal casing.
The film layer generated by anodizing itself has a large number of fine micropores. In the normal production process, these micropores need to be completely blocked by sealing treatment in order to firmly lock the dye inside.
The core root cause of this type of fading problem is that the sealing process of some batches of products is not done properly, and the micropores are not completely closed. The oil and sweat secreted by the user's daily use slowly penetrate into the inside of the oxide film, gradually destroying the internal dye molecular structure, and eventually causing discoloration and fading on the surface of the fuselage.
This generation of iPhone 18 Pro still continues the body material design of the same aircraft aluminum alloy and glass as the previous generation. There is no targeted adjustment in the process level for external publicity. The new fading problem this time is most likely directly related to the insufficient quality control stability of the anodizing and coloring process of the fuselage.
