If you have an iPhone 5s, there is a good chance that one or more of its water-damaged components have started to leak. If this is the case, you need to take action to fix the issue as soon as possible. The first step is to remove any water-damaged components from the phone. This can be done by using a hairdryer or a vacuum cleaner to suck out any water that has built up on the component. Once all of the water has been removed, you will need to replace any damaged parts. If you are not able to remove all of the water-damaged components yourself, you can call AppleCare and have them do so for you. AppleCare will also provide a replacement part for free if they find any damage on your phone.
