Apple's new patent application claims that a special metal coating could solve the color fading issues of current iPhone flagships. The U.S. Patent and Trademark Office published the tech giant manufacturer's research on Mar. 18.
According to Patently Apple's latest report, the giant company wants to use a doped metal oxide coating to protect its upcoming smartphones' metal casing. This new metal coating could be useful since MacRumors previously reported that iPhone 11 and iPhone 12 smartphones are currently losing the colors of their aluminum chassis.
Consumers complained that the side of their iPhone 12 has faded to an orange shade. This issue can often be seen near the power button.
On the other hand, it was also confirmed that the color fading was not caused by unwanted friction since the complainers used plastic or transparent cases.
How Apple's new doped metal oxide coating works
As of the moment, Apple hasn't confirmed when it will start using the new special coating. The company only explained some possible reasons why the consumers' iPhone smartphones are suffering from color fading issues.
"Enclosures for portable electronic devices may be manufactured from different types of metals, which may be colored with dyes in order to improve their aesthetic appearance," said Apple via Patently Apple's official website.
"For example, anodized coatings may be colored with various dyes," added the tech giant manufacturer.
On the other hand, Apple also explained that its innovation would be intentionally doped with a foreign atom or impurities. Aside from this, the next-gen iPhone's enclosure could also include a metal substrate and a metal oxide coating overlaying the said substrate.
Other issues of iPhones
Aside from color fading, some rumors also claimed that iPhone 12 flagships are also overheating.
Speculations stated that the overheating problem could have various possible causes:
- Apps with abnormal usage
- Overheating during and after initial setup
- Poor network reception
- Faulty unit
- Charging
