What to do if prompted with liquid has been detected warning on your iPhone 7 Plus (easy steps)

New iOS platforms particularly iOS 10 and later versions introduced a number of new features for end-user’s safety and security. One of these is a warning system that usually prompts whenever moisture is detected in the charging port. The warning message says that, “Disconnect lightning accessory. Liquid has been detected in the Lightning connector. To protect your iPhone, disconnect this Lightning accessory and allow the connector to dry.” There are only two possible reasons as to why you’re getting this warning message. Either it’s true that your iPhone’s charging port is damp, or it could be that your iPhone system is glitching.

If ever you too will get to encounter the same warning message when plugging your iPhone 7 Plus to charge or connect it to a computer, then thoroughly check the charging/Lightning port to ensure that it isn’t damp or wet. Doing so will prevent causing any damage to your device should the warning you see is true. If you find the totally dry and yet you’re still getting the same “liquid has been detected” warning on your iPhone 7 Plus, then most likely it’s a software glitch that requires troubleshooting. Read on to find out what to do to get rid of this warning message from your device.

For iPhone owners who found our site while trying to find a solution, try to see if your phone is one of the devices we support. If it is, then visit the troubleshooting page for that device, browse through it to find issues that are similar with yours and feel free to use our solutions and workarounds. However, if you still need our help after that, then fill up our iPhone issues questionnaire and hit submit to contact us.

First solution: Perform a soft reset.

If the inner port is not damp or wet, then software glitches are most likely to blame. To rule this out, performing a soft reset can help. A soft reset or device restart is the simplest possible solution to random errors and minor issues transpiring in mobile devices. It also clears and free up space on the internal memory for performance stability. Any corrupt data including temporary files or cache from within the app or phone system itself will also be cleared up in the process. If you haven’t restarted your iPhone yet, then do so with these steps:

  1. Press and hold the Power button until the Slide to Power off menu appears.
  2. Drag the slider to the right to power off your device.
  3. After 30 seconds, press and hold the Power button again until the Apple logo appears.

An alternative workaround to a soft reset is a force restart. Doing so will help clear any errant apps that might have triggered this warning to occur whenever you plug a cable into the charging/Lightning port.

To force your iPhone 7 Plus to restart, press and hold the Power and Volume Down buttons simultaneously for about 20 to 30 seconds and then release both buttons when the Apple logo appears.

Wait for your device to finish booting up and then try to plug in the Lightning cable or USB connector to the Lightning port. If the warning persists, then troubleshoot further.

Second solution: Manage apps.

Rogue apps can also be the trigger. Your iPhone system is comprised of various components including data segments, services, or apps and they are all interrelated. This denotes that if something goes wrong on any of these components, the phone system itself (iOS) gets affected. And this is when your device would start to misbehave. As remedy, you can try updating your apps to keep them optimized and bug-free. Otherwise, delete or uninstall errant apps. Updates usually embed fix patches to address certain device issues triggered by bugs and malware. If you didn’t configure your device to install updates automatically, then you will need to check for and update apps manually. Here’s how to update apps on your iPhone 7 Plus:

  1. Tap the App Store icon from the Home screen.
  2. Tap the Updates icon at the bottom right of the App Store main screen. A list of apps with pending updates will then show up.
  3. Tap the Update button next to an app to update individual apps.
  4. If multiple app updates are available, tap the Update All button instead. Doing so will update all apps simultaneously.

Wait until the update process is finished and then restart your iPhone to apply the new changes.

Third solution: Reset all settings on your iPhone 7 Plus.

You can try resetting all settings on your iPhone 7 Plus to clear the current settings including invalid options and erroneous configuration. This will restore the default system settings on your device so you will need to enable options that you need to use and disable those that aren’t needed. Here’s how it’s done:

  1. Tap Settings from the Home screen.
  2. Tap General.
  3. Scroll to and tap Reset.
  4. Tap to select Reset all settings from the given options.
  5. Enter your device passcode, if prompted.
  6. Then tap the option to confirm all settings reset on your iPhone.

Allow your device to complete the reset process, restarts, and then restores the default system values. Enable the features you need to use on your iPhone including Wi-Fi, Bluetooth, etc.

Fourth solution: Update your iPhone software to the latest iOS version available.

Installing the latest iOS update can be the key to resolving issue if it’s inflicted by system bugs or malicious software. iOS updates not only bring in new features but also embeds fix patch to rid of any existing bugs. Apple has by far released the iOS version 11.3.1 in the later part of April this year. To check if that version is already up for grabs on your iPhone 7 Plus, follow these steps:

  1. Go to Settings-> General-> Software Update menu.
  2. If you see a message saying that an update is available, tap Download and Install button to continue.
  3. To update software now, tap Install. Otherwise, tap Later and then select Install Tonight or Remind Me Later.

If you prefer to Install Tonight, plug your iPhone into power to ensure it has enough juice to get the update finished. Your device will implement the update automatically overnight.

Fifth solution: Reset your iPhone 7 Plus to factory defaults (master reset).

A master reset is often required to deal with major software issues. If the warning persists after exhausting all possible means to get rid of it, then it could be a complex system error that needs more advanced solutions. As your last resort, you can either reset your iPhone to factory defaults or restore your iPhone from a previous iOS backup.

To master reset your iPhone 7 Plus, navigate to Settings-> General-> Reset menu then select the option to Erase all content and settings. If prompted, enter your device passcode to continue and then confirm reset.

Please note though that this process will wipe all your data including personal information, customized settings and downloaded contents on your iPhone. That said, be sure to create a backup beforehand.

Alternatively, you can use iTunes to reset or restore your iPhone 7 Plus on a Windows or Mac computer instead. To get started you will need to connect your iPhone to your computer using the supplied USB cable so expect to get prompted with the warning again. Just dismiss the warning to continue to reset your iPhone in iTunes.

Other options

Contact your carrier or Apple Support to report the issue especially if it occurs after installing the latest iOS update on your iPhone 7 Plus. There might be some bugs that caused your device to show the liquid detected warning when a cable is plugged into the Lightning or charging port even if it isn’t wet. In that case, a fix patch would be necessary.

Alternatively, you can take your device to an Apple service center nearby and have it diagnosed by an authorized technician instead. Doing so will help rule hardware damage out from the possible triggers.
