iPhone 12 or later are IP68 water resistant, so why liquid damage can't be covered?
iPhone 12 mini, iOS 14
Because it’s not. Water resistance is not a permanent condition and does not guarantee that no liquid will enter the device and damage the internal components.
Liquid damage is not covered by the warranty.
Liquid damage is not repairable.
This is what Apple says:
About splash, water, and dust resistance of iPhone 7 and later - Apple Support
Water and other liquid damage to iPhone or iPod isn't covered by warranty - Apple Support
Any questions about "why" Apple does what they do should be directed to Apple. You can use the "Support" link at the bottom left of every page of these forums.
No. that’s not what they said. Those are the criteria used for testing under controlled laboratory conditions.
Your understanding of what water resistance ratings mean is flawed.
According to Apple, the IP68 means the phone can submerge into water up 6 meters for up to 30 minutes. So, if someone drop their phone into a bucket of water for few minutes, and the screen of the phone got damaged, why this isn't covered? If the phone was made to spec, it shall be able to survived from that condition but it wasn't.
