The iPhone 15 series, particularly the iPhone 15 Pro and iPhone 15 Pro Max, has introduced a new titanium frame, which, while innovative and aesthetically pleasing, raises several durability concerns. Here’s a detailed look at these concerns and what users need to know.
Material Comparison: Titanium vs. Stainless Steel
The shift from stainless steel to titanium in the iPhone 15 Pro and iPhone 15 Pro Max frames has significant implications for durability. Titanium is lighter and more ergonomic but less durable in certain aspects compared to stainless steel. Stainless steel frames, as seen in previous iPhone models, could absorb impact better due to their flat design, which helped distribute the force of a drop more effectively.
In contrast, titanium is more rigid, meaning any impact is more likely to be dispersed to other parts of the device, such as the front and back glass, leading to potential spiderweb cracking. This difference in material properties makes the titanium frame more susceptible to damage from drops and other impacts.
Drop Test Performance
Several durability tests conducted by various reviewers have highlighted the vulnerability of the titanium frame. For instance, in a 50-drop challenge comparing the iPhone 14 Pro to the iPhone 15 Pro, the iPhone 15 Pro cracked within 10 drops, primarily at the corners, while the iPhone 14 Pro remained unscathed. These tests indicate that the titanium frame may not withstand everyday drops as well as its stainless steel predecessor.
Structural Integrity and Bending Tests
Bending tests have also shown mixed results for the iPhone 15 series. The regular iPhone 15 Pro, with its titanium-aluminum hybrid structure, has withstood strong bends from both the back and front without compromising its integrity. However, the larger iPhone 15 Pro Max has not fared as well, suggesting that scaling the material for larger devices poses significant engineering challenges.
Scratches and Wear
The titanium frame, despite its PVD coating, is susceptible to scratches, similar to anodized aluminum. This vulnerability is evident in tests where the frame showed signs of wear after minimal exposure to abrasive objects like keys and coins. Additionally, the power button and action button integrated into the titanium frame have shown signs of wear, indicating that even meticulously applied finishes can be compromised with minimal use.
Practical Considerations for Users
Given the durability concerns associated with the titanium frame, users should take extra precautions to protect their devices. Here are some practical steps:
- Use a Protective Case: Investing in a high-quality case can significantly enhance the durability of the iPhone 15 Pro and iPhone 15 Pro Max. This is particularly recommended for users who are concerned about the susceptibility of the titanium frame to scratches and drops.
- AppleCare+: For those who prefer not to use cases, AppleCare+ can provide coverage for accidental damage, including up to two incidents of theft or loss per year, depending on the plan.
- Handling with Care: Users should handle their devices with extra care, avoiding situations where the phone might be subjected to significant impact or abrasion.
Additional Durability Concerns
Back Glass Durability
The back glass of the iPhone 15 Pro Max, which is in contact with the titanium frame, has also raised concerns. Some tests have shown that the back glass can break with minimal pressure, highlighting another area of vulnerability.
Discoloration
Another issue noted with the titanium frame is discoloration from fingerprints, although this can be easily resolved with a simple wipe.
By understanding these specific durability concerns, users can make informed decisions about how to best protect and maintain their iPhone 15 Pro and iPhone 15 Pro Max devices.
