Apple’s head of hardware engineering explains why iPhones are so hard to repair

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

Ternus explained that Apple's design philosophy aims to create products that rarely fail, which ultimately benefits 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.

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, which was a prevalent issue in the early days.

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.

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.
