The iPhone 12 has gained immense popularity due to its advanced features and sleek design. However, some users have reported experiencing issues with their devices not charging when plugged in. This problem can be frustrating and inconvenient, especially when relying on the phone for daily tasks and communication. Identifying the cause of this issue and knowing how to fix it is crucial for a seamless user experience.

Several factors might contribute to an iPhone 12 not charging when plugged in to a power source. These include damaged accessories, dirty charging ports, software bugs, or issues with the power source itself. It is essential to investigate each factor to ensure the device charges efficiently and smoothly.

This article will delve deeper into the possible reasons and solutions for an iPhone 12 failing to charge when plugged in. By understanding and addressing these potential issues, users can maintain an optimal charging experience and extend the lifespan of their devices.

Understanding iPhone 12 Charging Issues

The iPhone 12 occasionally encounters charging issues that prevent the device from charging properly. There are several possible reasons for this, ranging from hardware issues to software-related problems. Understanding the reasons for these charging issues can help users find the right solution to fix their iPhone 12 device.

One of the main hardware-related causes is a damaged iPhone charging port, cable, or adapter. This can occur from normal wear and tear or accidental damage. In such cases, users should inspect their cables and charging port for any signs of damage and replace them if necessary. Sometimes, dirt or debris can accumulate in the charging port or on the charging cable, preventing a secure connection. Gently cleaning the iPhone charging port using a dry, lint-free cloth can help to resolve this issue.

If the hardware seems to be in good condition, the issue might be related to software problems. A simple restart of the iPhone 12 can resolve many common issues. Users can do this by pressing and holding down both the Side button and either Volume button until a slider appears on-screen. Then, drag this slider across to power off the device completely. After waiting a few seconds, press-hold the Side button again to turn the device back on.

In some cases, it might be necessary to perform a hard reset on the iPhone 12, especially if a software problem is causing the screen to turn black. To do this, press and release the Volume Up button, then press and release the Volume Down button, and finally, press and hold the Side button until the Apple logo appears on the screen. After seeing the Apple logo, release the Side button and let the device boot.

For those using wireless charging methods like MagSafe, removing the iPhone case might help to improve the connection. Additionally, a hard reset is also recommended if the device won’t charge while using MagSafe.

If all the above-mentioned methods fail to resolve the charging problem, it is possible that resetting the device’s settings might help. To do this, go to Settings > General > Reset > Reset All Settings. Users may need to enter their passcode to perform this action. After resetting, the iPhone 12 should charge properly when connected to a charger.

In case the charging issue persists even after all these steps, the best course of action is to consult with an official Apple service provider. They can thoroughly diagnose the issue and recommend an appropriate solution to fix the iPhone 12’s charging problems.

Common Causes of Not Charging

One common cause of an iPhone 12 not charging when plugged in is using a damaged or fraying charging cable. It is essential to regularly check the Lightning cable for any signs of damage, as this can affect the charging process.

Another potential issue could be debris in the Lightning port or charging port. Over time, dust and dirt can accumulate in these tiny ports, hindering proper cable and connector connections. A simple fix for this issue is gently cleaning the port with a clean toothbrush or a toothpick.

Sometimes, a hardware problem can lead to charging issues. This can involve either the charger or the phone itself. It is recommended to try using a different charger or wall plug to isolate the problem. Additionally, USB ports on a computer or another power source can also be considered. Should the issue persist, considering a professional assessment of the device by an authorized service provider is advised.

In some cases, minor software glitches could be causing the charging problem. An effective way of addressing this issue is by performing a force reboot on the iPhone, which resolves a significant number of software-related issues.

Using non-MFi-certified (Made for iPhone) accessories can also cause charging problems. It is highly recommended to use MFi-certified charging cables and wall chargers to ensure compatibility and avoid potential damage to an iPhone.

Temperature can also impact the device’s charging process. Extremely hot or cold conditions may interfere with charging or cause the device to charge slowly. It is advised to remove any cases or covers during charging to help regulate the temperature and ensure optimal charging conditions.

Optimized Battery Charging, a feature designed to prolong the iPhone battery life, can sometimes contribute to charging issues. This feature delays charging the battery to 80% until it is time for the user to wake up or unplug the device. Disabling this feature can help resolve potential charging concerns.

Lastly, while the iPhone 12 is compatible with MagSafe chargers and accessories, users may experience different charging speeds based on the type of charger used. The phone will charge more rapidly with Apple’s 20W fast charger, while third-party chargers might not provide the same charging speeds. Ensuring that wireless charging pads and connectors are clean and compatible with the device can minimize connectivity issues and maximize the efficiency of charging.

Troubleshooting Steps for Charging Issues

If you’re encountering charging issues with your iPhone 12, iPhone 12 Pro, or iPhone 12 Pro Max, follow these troubleshooting steps to resolve the problem.

  • Check the Lightning cable and power adapter: Inspect the cable for any damage, such as fraying or exposed wires, as well as ensuring that both ends are securely connected. You should also try a different USB-C cable and/or power adapter to ensure they aren’t the cause of the issue
  • Examine the power source: Try plugging your iPhone into a different power outlet, a PC or Mac USB port, or using a power bank. Avoid using the USB ports on your keyboard or any other accessory that isn’t designed for charging
  • Clean the Lightning port: Dust and debris can accumulate inside the Lightning port, causing charging issues. Gently clean the port using compressed air, taking care not to damage any internal components
  • Restart your iPhone: Turn your iPhone off and back on again, as this can often resolve minor glitches. If the device is unresponsive, perform a forced restart by quickly pressing and releasing the Volume Up button, followed by the Volume Down button, and then pressing and holding the Side button until the Apple logo appears
  • Update to the latest version of iOS: Make sure your iPhone is running the latest version of iOS (iOS 16, at the time of writing). Software updates can fix bugs and improve device performance, including charging capabilities
  • Monitor battery icons and lock screen: Look for an iPhone battery icon or lightning bolt on the lock screen when your iPhone is connected to a power source, as this indicates that the device is charging. A battery life icon with a red line or no lightning bolt signifies a problem with the charging process
  • Enable USB accessories on locked iPhone: Some USB accessories may require permission to charge your device. Navigate to Settings > Face ID (or Touch ID) & Passcode > USB Accessories, and toggle it on
  • Reset all settings: If your iPhone is still not charging, you may need to reset all settings. Go to Settings > General > Reset > Reset All Settings. Note that this will not erase your data, but your device’s settings will be reverted to their defaults
  • DFU restore: If none of the above steps work, attempt a DFU restore, which stands for Device Firmware Update. This process completely reinstalls your iPhone’s firmware and resets the device to factory settings. Be sure to back up your data beforehand, as a DFU restore will erase all content on your iPhone

Keep in mind that although these troubleshooting steps are focused on the iPhone 12 series, they can also be applied to other iPhone models, such as the iPhone XR. Remember to be cautious when attempting any fixes, and consult Apple Support for further assistance if necessary.

Contacting Apple Support

If your iPhone 12 is not charging when plugged in, one of the first steps you should take is to contact Apple Support. Apple Support is available to assist with various issues, including problems related to charging.

Before reaching out to Apple Support, it is important to check if your iPhone is still under warranty. If your iPhone is under warranty, you might be eligible for a free repair or replacement of any faulty components responsible for the charging issue. You can also provide the serial number of your iPhone to the customer representative who can assist in determining the warranty status of your device.
