iPhone 15 Pro once again reduces weight and adopts titanium alloy mid-frame design

According to news on August 26, there have been recent reports that the designs of iPhone 15 Pro and Pro Max have undergone major changes and will use lightweight titanium alloy middle frames. This means that the new generation of iPhone will be lighter than the previous stainless steel material. Although the specific weight data has not yet been released, this change is expected to bring a new user experience to users

In the past few generations of iPhone designs, the Pro series has remained the same size and shape. However, the difference is the material of the mid-frame, which results in a weight difference of about 30 grams. The density of the aluminum alloy mid-frame is about 2.7 grams/cubic centimeter, while the density of stainless steel is as high as 7.7 to 8.0 grams/cubic centimeter. Now, news has emerged that the iPhone 15 Pro and Pro Max will use a titanium alloy middle frame with a density of approximately 4.5 to 4.6 grams per cubic centimeter. Although there is a certain density gap between titanium alloy and aluminum alloy, it is still lighter than stainless steel

According to the editor’s understanding, foreign media 9to5mac speculates that the new iPhone 15 Pro may be lighter than the iPhone 14 Plus Lightweight, and the iPhone 15 Pro Max, although still the heaviest model, is expected to be lighter by more than 14 grams. This prediction takes into account factors such as camera hardware and battery, and although there are many variables, these data still provide users with an initial reference indicator
