If your iPhone has water damage, it may not be working correctly. If you can’t turn it on or if the battery is low, then it’s likely that the phone has been damaged in some way. Here are a few tips to help determine if your iPhone has water damage: -Check the battery level: Make sure that the battery is at least 50% charged before checking for water damage. If it’s not, you may need to replace the battery. -Check the screen: Make sure that there are no tears or dents in the screen. If there are, then water may have caused them. -Check for any signs of corrosion: Corrosion can indicate that water has been present and may have caused other problems with your phone. Corrosion can also be a sign of a fire or other accident.
