Summary
- If your iPhone 18 Pro Max got wet recently, drying its USB-C connector properly should help get rid of the alert.
- If your iPhone’s connector is not wet at all, try using a different charging cable. Also, clean the charging port, restart your iPhone, and update iOS.
- It’s best to avoid overriding the “Liquid Detected” alert. If you need to charge your iPhone urgently, use a wireless charger instead.
Attempting to charge your iPhone 18 Pro Max but see an alert telling you that liquid has been detected in the connector? Let’s look at the troubleshooting steps you can take to resolve the “Liquid Detected” alert and charge your iPhone normally again.
1. Dry the USB-C Port
Even if you’re holding a dry iPhone in your hands, it’s safer to assume that the “Liquid Detected” alert is accurate. Keep in mind that while iPhones are water-resistant, they are not waterproof.
Therefore, if you dropped your iPhone into the water or went swimming with it recently, it’s highly probable that water got into the charging port. The solution to this is to dry the charging port on your device. To dry iPhone, tap it gently against your hand with the USB-C connector facing down to remove excess liquid. Leave the device in a dry area with sufficient airflow.
In the future, if you do want to bring your iPhone to the pool or a water sports event, you can consider purchasing a waterproof iPhone case that encloses your device entirely. Otherwise, you shouldn’t shower or swim with your iPhone, as Apple warns.
On the other hand, if you’re sure that your iPhone 18 Pro Max has been nowhere near water for the past several weeks, the “Liquid Detected” alert might simply be a glitch. In that case, let’s move on to the other solutions.
2. Troubleshoot the Charging Cable
The next step is to remove and reinsert the USB-C cable into the charging port because the accessory may not have been recognized correctly.
If that doesn’t work, try a different USB-C cable. If the alert only pops up when you use a particular cable, you know the issue is with the cable, not your iPhone.
There are lots of cheap, counterfeit Apple cables out there. It’s always best to purchase official or MFi-certified accessories to prevent compatibility issues and damage they might cause to your iPhone.
3. Clean Your iPhone’s Charging Port
If debris is stuck in your iPhone’s USB-C port, it may also cause charging issues. If necessary, gently remove the debris and clean the connectors on your device.
Don’t use cleaning products or compressed air.
4. Restart Your iPhone 18 Pro Max
The next troubleshooting step is to soft reset your iPhone. Simultaneously press and hold the side button and either volume button until the sliders appear, then drag the Power Off slider. Press and hold the side button until the Apple logo appears. Restarting is an effective solution for nearly all minor technical problems for any device, so it’s definitely worth a try to get rid of the “Liquid Detected” alert.
5. Update Your iPhone
Lastly, it’s best to update your iPhone 18 Pro or iPhone 18 Pro Max to the latest iOS version if you haven’t done that already. iOS updates carry bug fixes and performance improvements, which may help remove unnecessary warnings such as this one from popping up.
Go to Settings > General > Software Update on your iPhone to check if an iOS update is available.
Should You Use Emergency Override to Charge Your iPhone?
The “Liquid Detected” alert may provide an Emergency Override option to charge your iPhone, but is it safe to do so?
If you’re aware that your iPhone is still wet, you should not attempt to charge it with a wired charger, as it may permanently damage your device. A safer alternative is to charge your iPhone wirelessly but dry the back of your iPhone before doing so.
Remember that the “Liquid Detected in USB-C Connector” alert protects your device from permanent damage and ensures your safety. It’s certainly a hazard if an iPhone were to continue charging despite a wet USB-C port.
Still, the alert may sometimes pop up even if your iPhone 18 Pro Max isn’t wet. But by following the steps above, you should be able to resolve the error quickly and charge your iPhone again. If the problem persists, it’s best to contact Apple Support to see if there are other issues with your device.
