If your iPhone or iPod touch won't charge - Apple Support (IN)

The charging ports on iPhone are pretty durable and in most cases when iPhone doesn’t charge, it is because of debris and lint was collected in there, preventing the cord from charging. So use a toothpick and a flashlight, and get that out of there.

If you have very carefully cleaned out the port with a wooden or plastic toothpick and the problem remains, the battery itself may be at fault or there may be board problem on the iPhone.

Tap Settings > Battery > Battery Health & Charging and check on the Maximum Capacity of the battery. If it is under 80%, it is time to replace the battery.

Otherwise, there may be board problem or a physical problem with the port itself. Hopefully, that is not the case because Apple will not replace the port, they will offer a much more expensive board replacement or in some cases, a refurbished phone at a reduced price.

Make an appointment at the Apple Store / Genius bar, or it may be easier to take the phone to a local shop that is closer to your home. You can find a list of authorized service shops in your area using this link:
