Apple introduced water resistance with the i Phone 7 in 2016, marking a shift from earlier models that offered no protection against liquids. The feature was tested in real-world conditions, including submersion in a swimming pool, to evaluate how well the device withstands water exposure under everyday use. This early implementation laid the groundwork for improved water resistance in later i Phone generations.
The i Phone 7 carried an IP67 rating, meaning it could survive immersion in up to one meter of freshwater for 30 minutes. During testing, the device was submerged in a pool and used to take photos and videos underwater, demonstrating basic functionality despite the harsh environment. While touchscreen responsiveness decreased underwater, the phone remained operational after retrieval, confirming Apple’s claims for short-term exposure. Saltwater and chlorinated pools were not part of the official test parameters, leaving long-term effects uncertain.
Apple achieved water resistance through adhesive seals around the display and internal components, along with mesh covers over speakers and ports to block liquid ingress. These design changes allowed the i Phone 7 to resist splashes, spills, and brief submersions without immediate damage. However, the company emphasized that water resistance is not permanent and can degrade over time due to wear, temperature changes, or physical impact. Users were advised against intentional underwater use, even if the phone survived testing.
While the i Phone 7 could function briefly underwater, Apple did not recommend using it for photography or video recording beneath the surface. Touchscreen input failed when wet, requiring reliance on physical buttons to operate the camera. Images captured during testing showed reduced clarity due to refraction and light absorption, limiting practical utility. The experiment highlighted the difference between laboratory ratings and real-world usability, especially in dynamic environments like pools.
Is the i Phone 7 fully waterproof? No, it is water-resistant under specific conditions, not waterproof for indefinite or deep submersion.
Can I take my i Phone 7 swimming? Apple advises against it, as pools contain chemicals that may damage seals over time.
Does water resistance last forever? No, protection can diminish with age, repairs, or exposure to heat and pressure.
