Liquid Detected in Lightning Connector? Try These Fixes

liquid detection alert on iphone

After the iOS 10 update, iPhone users now receive a new error message that states “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.”

This is a warning message that can protect you and your device from permanent damage. However, disconnecting the Lightning connector isn’t enough, there are a few other things that you need to do after disconnecting the cable.

The reason why disconnecting the lightning connector isn’t enough is the fact that this error doesn’t necessarily mean that the lightning port is the one that’s wet or has a trace of moisture in it.

It could be other lighting accessories you use. It could well be a system glitch that could have prompted this error.

So, just to ensure that everything is in the right place, you need to apply a few precautionary fixing techniques to prevent further damage that liquid might bring.

Why Does Your iPhone Say Liquid Detected in Lightning Connector?


Your iPhone says Liquid detected in the lightning connector either because there’s liquid in your lightning connector, or you’re using the wrong lightning cable and there’s a glitch on your iPhone that’s letting you know that there’s a problem with your lightning cable indirectly.

Sometimes rather than letting you know that there’s an issue with your lightning cable, your iPhone will say that liquid has been detected in the lightning connector even if it’s not wet.

If you do notice that the lightning connector is wet, then you need to get liquid out of the lightning connector. If the lightning connector isn’t wet and you’re getting the error, then you need to change your lightning cable and fix the error.

1. Fake Lightning Cable

A fake lightning cable for your iPhone can make it send you false warnings about detecting liquid when it is not wet. The phone’s highly sophisticated system can detect a fake lightning cable, which is one of the effects.

Once this warning is launched, your phone will not be able to charge. If the problem is a fake cable, there is no solution other than getting an original lightning cable.

However, using a fake cable on your iPhone can cause other significant damages such as damaging the iOS, preventing the phone from syncing well, making the phone hot, and poor performance.

2. iPhone Software Out of Date

Your iPhone software is in charge of functions such as the liquid detector. As a result, when the system is outdated, there are high chances that such functions will be affected.

So if you are getting the “liquid detected” when you connect your lightning cable, and it is not wet, check for updates.

You can check whether your iPhone software is up to date by following these simple steps.

1. Go to your iPhone settings.

2. Scroll to the “General” options on the settings and tap to open.

3. Locate and tap on “Software Update”

If your phone software is up to date, you will get a message informing you.

If your phone software is out of date, you will get a message indicating an update available. You can click the install option to update the software.

3. Damaged Charging Port

Yes, a damaged charging port could be why you are getting a liquid detected warning even when the phone is not wet. There are several things that can spoil your iPhone charging port. Since the system detects wetness from the port, it is possible to get the wrong signal resulting in this warning.

When the charging port is damaged, other symptoms will be experienced in many cases.

Such symptoms include poor charging, slow charging, loose grip on the charging port, phone not charging, fluctuations in charging, and false liquid detection.

An iPhone charging port can be damaged by several things, including corrosion from foreign materials, debris, dust, dirt, bent connector, broken charging port, or a loose charging port.

4. Port Filled with Dust

Dust is a common foreign material that can make the charging port of an iPhone misbehave. As dust occupies your charging port, it creates layers that affect how well the phone detects your lightning cable.

This means that when you insert the lightning cable, the phone can detect and send wrong information of liquid available even when there is none.

Note that this is not a situation that will happen just within a single day of using your phone in the dust.

Instead, it is a situation that will take to manifest itself. So, it will take quite some time to build up dust in your phone’s charging port before it can be problematic to cause such issues.

5. You’ve Dropped Your iPhone in Water

The liquid detector system detects any wetness in the charging port. It will give you a warning whenever there is any wetness detected. So, if you have dropped your iPhone in the water, do not be surprised when you get this warning.

When you drop or touch your iPhone with water around the charging port, and the water gets in, it will send this warning. Even when you clean the phone, there might be some wetness left in the charging port that will cause this issue, and a warning will be sent.

3. Replace Cable with an MFI Certified iPhone Cable

As discussed earlier, one of the possible causes of a false warning of liquid detection in iPhones is a fake cable. If you have replaced your lightning cable recently, then there are high chances that you are using a fake cable.

It is crucial to investigate this and replace it with a certified cable. When replacing the cable, you must ensure that you get an original MFI Certified cable (view on Amazon). Here are the steps to check whether you are getting an original iPhone lightning cable.

1. The packaging must have an MFI badge. The cable will also have the words “Designed by Apple in California and assembled in (Vietnam/China). Next to this sentence will be a serial number with 12 digits.

2. Get a toothpick, then roll cotton product or a small piece of paper to form a small tip to fit into the charging port.

3. Carefully and slowly insert the tip with the cotton or paper piece into the port. Then jiggle the tip to touch the surfaces and loosen any dirt.

4. Now, use compressed air to blow all the loosened dirt out of the charging port.

You may now insert the lighting connector and turn on the phone.

5. Use Compressed Air or Blow into Charging Port

Compressed air can be used to clean the charging port and remove any debris that may be causing the error.

1. Start by turning off the phone. Next, go to settings, click on general and click shut down.

You first need to have a wireless iPhone charger. You can use a MagSafe wireless charger (view on Amazon) for this case. The charger will allow you to charge your phone just like a normal charger.

It is also a good route to take when you detect water in your charging port. Using a wireless charger will keep you connected until you can fix the charging port issue.

7. Remove the Lightning Connector/Charging Cable and Power Off the device

The most logical thing to do after receiving this warning is to remove the lightning connector or charging cable from the iPhone.

However, that alone is not enough; you will also need to power off the device for at least an hour. Once the iPhone is switched off, place it in a dry and warm place. Do not shake your iPhone and do not blow into the port.

Importantly, do not attempt to charge your iPhone regardless of how low the battery is. Air-dry the lightning accessory to make sure it has been properly dried before using it with any device.

After an hour or two, try turning on your iPhone to see if the error still shows up or try to connect the accessory to know if the error is triggered again. If it shows up then do you should consider taking your iPhone to an authorized Apple Store for better advice.
