iPhone
Modern iPhones incorporate Ceramic Shield front covers and aerospace-grade aluminium frames, achieving IP68 water resistance ratings. Laboratory testing indicates survival rates of drops from heights up to 1.8 metres onto concrete surfaces, though real-world performance varies considerably.
The average iPhone lifespan extends to approximately 4.5 years before hardware obsolescence or battery degradation necessitates replacement. Planned obsolescence through software updates has drawn criticism from sustainability advocates, though Apple has recently extended support cycles to address these concerns.
