The Apple iPhone 6s and 6s Plus are more resistant to water damage than their predecessors, according to iFixit.
The company tore down the new iPhones and discovered the frame supports a gasket that helps protect against liquid ingress. Moreover, cable connectors on the logic board — a weak link in any electronic device — are sealed with silicon.
iFixit notes that Apple did not take any apparent measures to protect the speaker nor the SIM card tray, which still allow some liquid to seep in. The subtle changes made by Apple do appear to help the phone survive quick dunks in water, as evidenced by various videos posted across social media, but Apple is making no claims about the new iPhones being waterproof or even water resistant.
