How to eject water from your iPhone 
Did your iPhone take a dive into the water? You usually don’t have to worry, as all modern Apple smartphones have a good level of water resistance. The iPhone 14 series (and most other recent iPhones) come with an IP68 rating. Apple claims it can be submerged up to six meters of water for as long as 30 minutes. This doesn’t mean leaving water in the phone’s crevices is good, though. This is why the Water Eject iPhone feature can be a helpful tool to get liquids out of speakers.
To use Water Eject on the iPhone 13 (or any iPhone with iOS 14 or newer), you'll need the Water Eject Shortcut. Download the Shortcuts app from the Apple App Store. Then open Safari and go to ShortcutsGallery.com. Find Water Eject and go into its Shortcut page. Select Get shortcut, and the Shortcuts app will open it. Tap on Add Shortcut, hit the Water Eject Shortcut, select Start, and pick an intensity level.
