How Google tests Pixel smartphones for durability: engineers reveal details

Google has shared details of the durability testing process for its Pixel smartphones. In a new blog post, the company described how its product engineering team ensures that the devices can withstand daily use and damage.

Here's What We Know

The process begins with studying real-world situations in which users might use their phones. Based on these scenarios, the team develops tests that are repeatable and scientifically based. For example, they investigate why certain components, such as internal connectors, might loosen and work with designers to fix these problems. This approach is called Failure and Design Effect Analysis.

Google tests its phones for real-world conditions to ensure that they can withstand unforeseen situations like being dropped or damaged and remain intact - without a cracked screen or a faulty camera.

Specific tests include the use of a robotic arm that simulates the constant packing and unpacking of a bag, repeated drops of tablets from low heights, and vibration testing using a special machine. Tests are also carried out at altitudes up to 14,000 feet to check how the device can withstand the unpressurised cockpit environment.

Temperature tests simulate real-world situations, such as leaving a phone in the sun on a hot summer day or subjecting it to sudden temperature changes when moving from warm rooms to cold. Devices are tested in a temperature range from -30ºC to +50ºC (or +60ºC) to simulate real-world situations.

One of the most interesting aspects of the testing process is the product's design margin. Google asks itself the question: "How many more drops can a phone withstand if 90% of users drop their devices a certain number of times a year?" This allows them to create phones that not only withstand standard accidental damage, but also last longer.
