Also note than when your iPhone is successfully charging, you will see a lightning bolt next to the battery icon in the status bar if your iPhone is unlocked. If it is locked or if it is powered off, you will see a big battery icon. Sometimes you may see a message saying “Not Charging” when plugged in which indicates that there are some issues ranging from a faulty or damaged cable to intermittent connections.

Dealing with a phone that has stopped charging can be extremely frustrating. But do not worry. You may easily fix it. If your phone refuses to charge the battery, here is what you can do:

1. Are you plugged in? Yes, this sounds silly but check anyway. Make sure that your iPhone is tightly plugged in and it is connected to a power source. Furthermore, make sure that you hook up everything as it should be. Look at each contact. There should be only a very minimal wiggle room.

2. Check your cables and adapter. Make sure that you are using the cable and adapter that came with the iPhone.

  • try a different cable and adapter.

3. Check the power source. It is possible that your iPhone or your cable and adapter may not be the problem, the problem may be the power outlet. You may want to try a different power source:

  • If you’re trying to charge from the wall, try even a different wall outlet. Make sure that the wall outlet is functioning properly.
  • If you’re charging from a USB port, try a different port and if that does not work, plug iPhone directly into a wall outlet.

4. Maybe your charging port is dirty? One of the causes of your iPhone’s charging problem is dust, lint, and debris. It is possible that this dust and dirt can keep the connector from making an electrical connection. This means that it is possible the lightning port may be clogged. This can cause your charger port to stop working. Try cleaning out the port with a toothpick, and then try again. Please follow the tips below:iPhone charging port

    • (other iPhone models): pressing and holding the power (side or top) button until you see the power off slider. Then drag the slider.
  • Use a flashlight to lit the port, and carefully look for any material. If you see anything:

Do not use a paper clip or pin. You may damage your iPhone’s charging port permanently. Do not damage the charging port. Be gently.
  • You may repeat this step until the port is cleaned.
  • And then turn on your iPhone. To do this, press and hold the power button (side or top) until the Apple logo appears.

  1. It appears to be the charger, not the phone, as my phone charged quickly and easily using a different charger belonging to somebody else.
    Is it possible to get a new charger, please?

  2. Mine won’t charge unless I use the Apple brick or a mobile charger. The cord doesn’t matter, but must have genuine Apple brick.

  3. Check to make sure there is not lint or junk in the connection port on the iPhone. This builds up over time, especially for men that keep the phones in their pockets all the time. Use a tiny pin to scrap it out or clean it. this is usually the first thing to check!
