3、Intermittent Charging

• Charging stops and resumes randomly while connected to the charger.

You can use the following to detect the reasons why the iPhone charger is not working properly

• Test with Other Devices:Plug the charger into another iPhone or iPad. If other devices also don’t charge, the issue may lie with the charger or cable.If the other device charges properly, the problem could be with your iPhone (such as the battery or charging port).
• Try Different Charging Cable or Adapter:Use a different cable and charging adapter. If the iPhone charges with the replacement, the original cable or adapter may be damaged.If the issue persists, the power outlet or iPhone’s charging port might be faulty.
• Check for Physical Damage:Examine the charging cable for any visible damage such as frays or breaks, which could cause unstable or no charging.Ensure the cable fits snugly into both the iPhone and the adapter. If it feels loose, a replacement cable may be needed.
• Check for Dirt in the Charging Port:Dirt, dust, or lint in the iPhone’s charging port could cause connectivity issues. Use a soft brush or compressed air to carefully clean it.
• Look for Charging Messages:If you see a message like “This accessory may not be supported,” it usually indicates a compatibility issue or a faulty charger or cable.
• Monitor for Overheating:If the charger or cable overheats quickly, this could indicate a malfunction. Stop using the charger to prevent further damage.
• Try a Different Power Source:Test the charger with a different power outlet or USB port. If it still doesn’t work, the charger may be defective.
• Use Original or Certified Accessories:Ensure you’re using an Apple original or MFi (Made for iPhone) certified accessory. Non-certified third-party accessories can cause charging issues.
