Buying a New Phone: Controlled experiments

Laurel is in the market for a new phone after cracking the screen on her old one. Her next phone choice will be based on which is more durable: the WePhone 10S or the Universe S10. She looks at a YouTube channel video where the host buys one of each phone and tests how much force is needed to crush each phone with a hydraulic press. If every WePhone or Universe from the factory is truly identical and if the phones are tested under exactly the same condition, then is just one crushing test enough to determine durability?
