IPhone 14: Apple would replace the steel of the shell with titanium to reduce its weight
Will it soon be the end of steel on the iPhone? This is what JPMorgan Chase reports, which predicts that the iPhone 14 will instead be made of titanium. This transition will have several advantages, such as making it much less heavy while maintaining its current strength.
The iPhone 13 does not yet exist as rumors about its successor are already swirling. More than a year before the release of the iPhone 14, we know in particular that Apple plans to launch a model with a 6.7-inch screen, marketed at a price of around 1000 euros. As usual, this will not be the only innovation the manufacturer has in stock. According to a report by JPMorgan Chase, the latter also predicted that the Pro model will be made of titanium, replacing the steel commonly used. Production would be delegated to Foxconn, the usual manufacturer of Apple smartphones.
Why this change? Titanium has several advantages over other alloys. First, it is much more resistant than aluminum while being 60% heavier. However, it is just as effective in protection as steel, but is still 40% lighter. Note that titanium is widely used in the manufacture of traditional watches. Since the Apple Watch 5, Apple has also adopted this material.

Lighter iPhone 14, but also more prone to scratches
Despite everything, titanium is not free from flaws. To begin with, it is more expensive than steel, which would explain why Apple would reserve it for higher-end models at first. Moreover, it gets dirty more easily and tends to get scratched quickly. Apple seems to be aware of these problems, since it recently filed a patent for a chemical solution supposed to reduce the risk of degradation. So hopefully she will be up to the task.
In addition, the JPMorgan Chase report discusses the absence of iPhone 14 Mini in the range. This is not the first time that such a possibility has been put forward, knowing that it would corroborate with the bitter commercial failure of the iPhone 12 Mini, of which Apple was forced to stop production. Instead, the Cupertino company would offer a bigger iPhone, but still entry-level.
