Why does the water resistance effect of the Xiaomi 14T fail?

Question

Accepted Answer

Water resistance can fail due to wear and tear, such as damaged seals or ports, exposure to chemicals, or drops that compromise the integrity of the device. Over time, even a phone rated for water resistance can lose its effectiveness. The Xiaomi 14T supports a dust and water resistance level of IP68. The IP68 rating requires still water under 2 meters deep, a test duration of 30 minutes, and a temperature difference between water and the phone not exceeding 5°C. The IP68 protection can degrade due to wear, impacts, high humidity, or corrosive environments. Please avoid using it in harsh conditions, and do not charge the phone in wet conditions, as liquid damage is not covered under warranty in many countries and the repaired device will not support the IP68.
