The iPhone 15 Pro and iPhone 15 Pro Max use Grade 5 titanium instead of stainless steel, making both flagships lighter and better at dispersing heat than the previous material, according to Apple. The company has recognized the overheating problems that continue to plague the two models but states that the software and not the new design is the reason for this string of issues.
Speaking with Forbes’ David Phelan, Apple compared the new titanium chassis on the iPhone 15 Pro and iPhone 15 Pro Max to stainless steel that it used on previous versions for several years. While analyst Ming-Chi Kuo has mentioned that the use of titanium and an inadequate cooling solution are the culprits behind the overheating problems, Apple believes otherwise, according to Phelan.
“What’s more, Apple has been consistent about how titanium, in conjunction with its aluminum substructure, is great at dispersing heat. Better, indeed, than any previous stainless steel iPhone Pro model. The design of the iPhone 15 Pro and iPhone 15 Pro is not causing overheating, Apple says.”
Apple might have thoroughly investigated the problem, which is why it is said to issue a software update in the next iOS 17 release to address these overheating issues, and also mentions that the update will not gimp the performance of the A17 Pro. Irrespective of Apple's belief that titanium is a better material at dispersing heat than stainless steel, a slew of evidence reveals that it is not as durable.
During the iPhone 15 Pro and iPhone 15 Pro Max launch date, a series of drop tests separated the camera housing of the newer model, while the stainless steel version chugged along quite nicely. Titanium is also prone to scratches, forcing customers to make an extra case purchase
