A YouTuber named Marquees Brownlee, also known as MKBHD, was recently invited by Apple to visit one of their laboratories. In this laboratory, there are various advanced machines used to test the durability of iPhones before they are released to the market. That's why MKBHD shared some short videos on X that show the behind-the-scenes process of how Apple tests water resistance (IP rating), drop resistance (drop test), and vibration resistance on iPhones.

MKBHD explained about IP rating testing for the iPhone. He mentioned that there is a special room used to test the water and dust resistance of the iPhone. To test water resistance alone, Apple goes through four different processes, namely: 1. First, a rainwater test is conducted by placing the iPhone under a special device that drips water like rain, but without pressure. 2. Next, a low-pressure jet spray is performed using a special device that sprays water onto the iPhone from all directions.

Vibration testing is designed to simulate the use of the iPhone in everyday situations, such as when used while riding a motorcycle or traveling on the subway. Although the durability tests conducted by Apple are not as rigorous as those conducted by YouTubers like JerryRigEverything, Apple performs testing on a much larger scale. They often test more than 10,000 iPhones before releasing them to ensure their strength and durability.
