iPhone is one of the most popular smart devices in the world. Unfortunately, it is prone to issues like not charging when you plug in. This can be frustrating and cause many problems if you rely on your device to stay connected. This can lead to various other issues, including but not limited to battery drain, slow charging, and completely drained batteries.

Fortunately, you can take a few steps to try and fix the issue of the iPhone not charging when you plug in. Before proceeding, ensure your charger is compatible with your device. If the charger is incompatible, this could be the root of your problem, and a new charger may be needed.

What Are The Causes Of The iPhone 12 Not Charging?

The most common causes of iPhone 12 not charging when plugged in are:

  • Damaged Lightning Cable – The most common reason iPhone 12 devices fail to charge is due to damage done to the lightning cable. If your charger has been bent too much, then it’s likely that the wires inside have been damaged, preventing a proper connection between your device and charger.
  • Faulty Charger – If your device is not responding to charging, the charger itself may be faulty. The best way to diagnose this issue is by using another charger to see if that resolves the issue.
  • Software Problem – If your device is not responding even when using another charger, it’s worth checking if a software problem is a cause. Try restarting your device or doing a factory reset to see if this fixes the issue.
  • Damaged Charging Port – If the charging port has been damaged, then, likely, your device will not respond to charging. If you have tried all of the above and it still doesn’t work, then it’s likely that your charging port needs to be replaced.
  • Battery Health – It’s also possible that the battery health is poor, meaning your device will not respond to charging. This can be checked using a third-party app or the Apple store.

How To Fix iPhone 12 Not Charging When Plugged In

Do you have an iPhone 12 that won’t charge when plugged in? If so, you can try several methods if your iPhone 12 is not charging when plugged in. Below are some troubleshooting steps that may help you resolve this issue:

1. Check The Charging Port, Cable, And Adapter

Sometimes, the issue can be due to a faulty charger, cable, or adapter. Ensure the charging cable is securely connected to your iPhone 12 and a power source. Check the Lightning port on your device to see if it is clogged or dirty. If so, use a clean toothbrush to remove debris from the port.

After doing so, reconnect your charging cable and try to charge your iPhone 12 again.

If your charger is defective, you can try charging your device with a different charger, cable, and adapter. If the problem is resolved after switching to a new charger or cable, then the issue is most likely due to a faulty charging device.

When purchasing a new charger, make sure it is an Apple-approved device.

2. Reset Your iPhone 12

Minor glitches can sometimes cause the iPhone 12 not to charge when plugged in. In this case, resetting your phone can be the answer. Software errors or minor malfunctions can be easily solved by resetting your phone. To do this, you need to follow these simple steps;

  • Press and hold the Volume down button, then press and hold the Power/Side button simultaneously.
  • You should release both buttons when the Apple logo appears on your screen and Power Off your device by sliding the switch.
  • Once the device is off, press the Power button until you see your Apple logo again.
  • Your device will reboot, and your phone should start charging when plugged in after successful restarting.

3. Update Your iPhone’s iOS Version

Your iOS version could be to blame if your iPhone 12 is not charging when plugged in. Make sure you’re running the latest iOS version available for your device. This makes your iPhone compatible with the latest technology.

To update your phone’s iOS, open Settings > General > Software Update. Tap Download and Install if an update is available. You may also connect your device to a computer and use iTunes to update it. Make sure you back up all your data before updating, just in case. Once complete, try charging your iPhone 12 and see if it works.

4. Reset All Settings On iPhone 12

If your iPhone has some misconfigured settings, it can cause the iPhone 12 not to charge when plugged in the issue. Resetting all settings will restore the configurations to their defaults, which can resolve the problem. To fix this problem, you can reset all settings on your iPhone 12.

Here’s how to do it:

  • Launch the “Settings” app on your iPhone 12 and select “General.”
  • Scroll down to the bottom of the page and tap “Reset.”
  • Tap “Reset All Settings” and enter your passcode if asked.
  • Tap “Reset All Settings” again to confirm.

After resetting the settings, the issue should be fixed, and your iPhone 12 should charge properly when connected to a charger.

5. Restore iPhone In Recovery Mode

Recovery mode is used to repair iOS system problems. You can try restoring your iPhone from recovery mode to see if that solves the charging issue. To put your iPhone into recovery mode, press and quickly release the Volume Up button, then do the same with the Volume Down button.

Sometimes, the issue isn’t with the iPhone but the power source. Try a different outlet or power source if your iPhone 12 is still not charging when plugged in. If you use a wall outlet, try a different one or a USB port with your charger instead.

Don’t forget to check if the outlet is working by plugging in another device. You can also try using a different charger or a computer USB port to see if the iPhone 12 charges. If the issue is with the power source, your iPhone should start charging once you switch to a different outlet or power source.
