My iphone xs got wet and after charging some buttoms starting to fail. It still has warranty. Pls provide other options?

As mentioned by the others, the basic hardware warranty does not cover liquid damages on a new Apple products. However, if you purchased an additional AppleCare+ service plan, it may be covered as one of the two "accidental" damages at a reduced repair cost. The price quoted would be determined by the Apple technician and based on either a repair (if possible) or.a replacement phone. Note that a replacement may not necessarily be with a new phone but could potentially be a refurbished model.

Water damage is not covered by the standard warranty and the device can't be repaired and must be replaced.

The warranty was voided when it suffered liquid damage.

You can pay for an out of warranty replacement or buy a new phone.

Liquid damage is not repairable.

Doing so will forfeit all rights to an out of warranty replacement from Apple.

Apple does not sell iPhone parts. Unauthorized service providers do not have legitimate access to Apple parts.
