Apple’s Head of Hardware Engineering Explains Why iPhones Are So Hard to Repair

In a recent interview with popular tech YouTuber MKBHD, John Ternus, Apple’s Head of Hardware Engineering, provided valuable insights into why iPhones are notoriously difficult to repair. The discussion, which was posted on X (formerly Twitter), delved into Apple's approach to balancing durability and repairability in its smartphones, offering a deeper understanding of the company’s design philosophy.

 
Design Philosophy: Durability Over Repairability

 

Ternus explained that Apple's primary goal is to create products that rarely fail, ultimately benefiting both customers and the environment. He contrasted this with products that are easy to repair but less reliable. According to Ternus, a highly durable product is more advantageous for users and environmentally friendlier, as fewer repairs translate to less material usage and waste.

 

Apple's commitment to durability involves designing devices that can withstand various forms of damage. One critical aspect of this durability is the iPhone's battery. While batteries inevitably wear out and need replacement, Ternus highlighted that Apple’s long-term improvements have significantly reduced other common failures, particularly water damage. Over the years, Apple has enhanced the water resistance of iPhones, achieving an IP68 rating. This rating has led to almost no incidents of water damage, a prevalent issue in the early days.

 

Innovations and Challenges in Durability

 

Ternus recounted stories of customers retrieving their iPhones from water after weeks and finding them still functional, a testament to the robustness of Apple's design. However, achieving such high durability involves using many seals and adhesives, which complicates repairs, especially battery replacements. Despite these challenges, Ternus assured that Apple provides solutions for necessary repairs, like battery replacements, while maintaining the overall reliability of the device.

 

He asserted that the reduction in failure rates has also positively impacted the environment. Fewer repairs mean less frequent use of new materials to replace damaged parts, aligning with Apple's environmental goals. Ternus pointed out that there is a threshold where making a device slightly harder to repair can be justified by its enhanced durability, benefiting customers and the planet.

 

Environmental Considerations and Criticism

 

Apple’s approach has faced criticism, especially from advocates of the right-to-repair movement, who argue for easier access to device repairs. However, Ternus' explanation sheds light on the company’s rationale. By focusing on creating durable products that require less frequent repairs, Apple aims to provide a better overall experience for its customers and contribute to environmental sustainability.

 

Why iPhones Are So Hard to Repair

The right-to-repair movement has gained traction globally, pushing for legislation that would require tech companies to make their devices more repair-friendly. Critics argue that the difficulty in repairing iPhones forces consumers to buy new devices instead of repairing old ones, contributing to electronic waste. However, Ternus emphasized that Apple's design strategy is aligned with long-term environmental benefits by reducing the need for frequent repairs and replacements.

Balancing Customer Experience and Environmental Goals

Apple’s approach to product design is a balancing act between creating a seamless, high-quality user experience and achieving environmental sustainability. By making iPhones more durable, Apple reduces the frequency of repairs and replacements, which in turn lowers the demand for raw materials and decreases electronic waste.

This strategy is evident in Apple’s broader environmental initiatives, such as using recycled materials in their devices and aiming for a carbon-neutral supply chain by 2030. Ternus’ insights highlight that while repairability is important, durability plays a crucial role in reducing the overall environmental impact of consumer electronics.

Looking Ahead: The Future of Durable Design

As Apple continues to innovate, the company remains focused on enhancing the durability of its products while addressing repairability concerns. Future iPhone models will likely incorporate new technologies and materials that further extend their lifespan without compromising on performance or user experience.

The company’s ongoing efforts to improve device durability and environmental sustainability reflect a commitment to responsible innovation. By prioritizing long-term reliability and minimizing the need for repairs, Apple aims to lead the industry towards a more sustainable future.

Conclusion

John Ternus' interview with MKBHD provides a comprehensive look at Apple's design philosophy regarding the durability and repairability of iPhones. While the complexity of repairing these devices poses challenges, Apple’s focus on creating robust, long-lasting products offers significant benefits for both customers and the environment. As the debate over right-to-repair continues, Apple’s approach underscores the importance of balancing immediate repair needs with long-term durability and sustainability goals.
