When is it Apple presented in September 2023 iPhone 15 Pro i iPhone 15 Pro Maxthe titanium frame was the main star of the marketing campaign. Description strong and light titanium design it stood at the very top of the official announcement. Of course, with the explanation that it is this one precious metal enabled the creation of the lightest Pro models in the company’s history.
However, with the arrival of the series iPhone 17 Protitanium has quietly and without much fanfare disappeared from the flagship model. He replaced it – aluminum. Although Apple has never publicly explained this decision, technology analysts and official design data clearly reveal three key reasons for this turn. These are cooling, functionality and savings, of course.
Lesson learned from overheating chips
To understand this change, we have to go back to the iPhone 15 Pro launch. Those models introduced the powerful A17 Pro chip, but early buyers immediately faced a serious overheating problem. Apple temporarily fixed it with a software update. Also, the code iPhone 16 Pro series Apple has somewhat improved the heat dissipation, keeping the titanium frame.
The real hardware cure has arrived with the completely redesigned iPhone 17 Pro series. Apple has built an advanced into these phones steam chambera component that Android flagships have been using for years, but for its maximum efficiency, titanium had to be written off.
Apple„Built with an Apple-designed vapor chamber laser-welded into a strong, lightweight and heat-conducting aluminum unibody, iPhone 17 Pro and iPhone 17 Pro Max deliver our best performance yet,” Apple said in its announcement, subtly explaining the move to 7000 series aluminum, BGR reminds us.
Although titanium is a superior material in terms of weight-to-strength ratio, it is poor heat conductor compared to aluminum. In the case of the iPhone 15 Pro, the internal structure was made of aluminum, while the titanium was only the outer shell. The new iPhone 17 Pro design uses a full aluminum unibody with a vapor chamber, allowing heat to efficiently spread and dissipate across the entire body. The result? Thanks to this cooling, the new A19 Pro chip achieves up to 40% better sustained performance compared to the predecessor. This is crucial for AI models, video editing and demanding games.
Hidden benefits of aluminum
In addition to solving the heat problem, the return to aluminum brought Apple a number of other design and financial advantages. Some of them are:
- Cheaper and easier production. Titanium is expensive, but its machining is even more expensive and demanding. Aluminum is much easier to shape, which drastically reduces production costs.
- More battery space.: The aluminum body allowed the company to enlarge the top camera module (which now houses other vital components), freeing up space in the bottom of the phone to fit a noticeably larger battery.
- Better signal and new shades. The antenna system is now much better integrated along the outer edges of the device. Also, aluminum enables the application of more vivid and attractive finishing colors, which was proven by the great success of the new one Cosmic Orange shades. It was impossible to perform it on titanium at that level of aesthetics.
Titanium is not finished, it is saved for the thinnest devices
Although it lost the performance and cooling battle with the Pro model, titanium has found a new purpose in the Apple ecosystem. And that, where structural strength is the only priority.
The best example is iPhone Airwho is proud with a revolutionary titanium design that is elegant and light, and at the same time incredibly strong. Of course, that’s what Apple says. Since the iPhone Air is the thinnest iPhone yet (5.6 millimeters), a titanium frame was necessary here to prevent the device from bending.
For the same reason, insiders claim that the upcoming iPhone Foldwhose premiere is expected in September, also use titanium. And not only for the outer frame, but also the elements of the complex screen hinge.
