How Apple Durability Tests New iPhones [Video]

Check out this inside look at Apple's durability labs where new iPhones undergo rigorous testing to ensure they meet the company's high standards of durability and reliability before hitting the market.

In a recent Twitter thread, popular YouTuber Marques Brownlee, also known as MKBHD, detailed the various testing methods employed by Apple to ensure their devices can withstand everyday wear and tear.

Water and Ingress Testing


Brownlee's first revelation was about the water testing process for iPhones to achieve their IP ratings. He shared a video demonstrating a room full of machines dedicated to this purpose. The testing levels include:


• IPX4: Simulating rain with a drip tray, applying no real pressure.
• IPX5: A sustained, low-pressure jet spray from any angle.
• IPX6: High-pressure spray from a firehose.
• IPX8: Locking the phone underwater with added pressure to simulate depth for an extended period.





Drop Testing


Apple has invested in an industrial robot to conduct drop tests. This robot can simulate hundreds of different drop angles onto various materials. Ultra-bright lights and high-speed cameras capture these tests, allowing engineers to observe the titanium frame's reaction upon impact in slow motion.




Frequency Exposure Testing


Brownlee also highlighted a unique testing method where devices are subjected to computer-controlled frequencies. This test simulates the vibrations a device might endure from a motorcycle engine or a subway car over time. Although difficult to capture on camera, this method ensures that iPhones can withstand sustained frequency exposure.




Insights from Apple's Head of Hardware Engineering


Brownlee also interviewed John Ternus, Apple's Head of Hardware Engineering, about durability and repairability. Ternus said that iPhone is harder to repair due to the trade-offs necessary to maintain the device's structural integrity.




Evolving Repairability


Brownlee noted that Apple is gradually softening its stance on repairability. The company is moving slightly along the durability vs. repairability spectrum, making strides to improve the ease of repairing iPhones without compromising their durability.




Real-World Testing


Connecting the dots between lab tests and real-world performance, Brownlee revealed that Apple tests over 10,000 pre-release phones before launching a new model. This extensive testing ensures that each device meets Apple's stringent quality standards.
