Fix, iPhone 8 is Charging Very Slow

Use Original Power Adapter

Some third-party chargers may not have the desired output power for your iPhone so it will take a lot longer for the battery to become fully charged. This is one of the main reasons why it is but highly recommended to use only OEM or Apple-supplied charger for your iPhone.

Check Power Source Properly

To make sure the problem is not due to the power source, try to switch between power outlets or power sources. You can use three power sources when charging your iPhone including wall power outlet, computer USB port (2.0 or 3.0), and power accessories like a powered USB hub, docking station, or other Apple-certified accessories.

When charging from a computer USB port, be sure that the computer is turned on and not in sleep mode. But then again, the supplied power from computers or power accessory may not be similar to that from the wall power outlet. So it’s still possible for your iPhone to charge slowly.

Check Lightning Cable for any Physical Damage

Examine both ends of the USB cable or Lightning cable you use to charge your iPhone. Note that Apple’s Lightning cables are prone to fraying especially at the end that connects to your iPhone. If ever you see any visible signs of damage, then you need a new cable.

Properly Clean the Lightning Port

Any debris or gunk in the port can prevent the lightning cable from making solid contact with your iPhone so it’s possible that your device won’t charge or may charge but very slow. If necessary, brush it out with something that won’t conduct an electric charge to prevent causing any damage to the electronics components at the bottom of your phone.

  • Press and quickly release the Volume Down button.
  • Press and hold the Side/Power button until the Apple logo appears.

  • These apps are in standby mode and running in the background.

  • Press and quickly release the Volume Down button.
  • Press and hold the Side/Power button when you see the Connect to iTunes screen. Do not release the buttons when you see the Apple logo since you’ll need to enter recovery mode.
  • On the next screen, you should see the option to Restore or Update.
  • Select Update first to update iOS. Otherwise, select the option to Restore.

Wait for iTunes to attempt to reinstall iOS without erasing your data. iTunes then downloads the software for your device. If the download takes more than 15 minutes, your iPhone exits the Connect to iTunes screen. If this happens, wait until the download is finished then go back to the previous steps to enter recovery mode again.

Restore your iPhone in iTunes via DFU mode

It’s regarded as the deepest type of system restore you can do on your iPhone. It allows your device to communicate with iTunes on a computer without loading the operating system or bootloader


Here’s how to perform a DFU mode restore on your iPhone 8:

  • Close any running programs on your computer.
  • Connect your iPhone to your computer using the Apple-supplied USB connector or Lightning cable.
  • While your phone is connected, press and hold the Side/Power button for about 3 seconds.
  • Keep pressing on the Side/Power button then press and hold the Volume Down button for about 10 seconds. If the Apple logo appears, it means you’ve held the buttons too long and that you’ll have to start all over again.
  • If you see no logo, release the Side/Power button but keep holding the Volume Down button for another 5 seconds.
  • If the screen stays black afterward, it means that you have successfully entered DFU mode. At this point, you will be prompted with an alert message on your computer saying that iTunes has detected your iPhone. If you see that message, follow the onscreen prompts to complete the DFU mode recovery process.
  • If you see the Plug into iTunes screen, it means you haven’t entered DFU mode and that you will need to start all over again.

If none of that works, then most likely what you’re dealing with is a hardware problem.
