If your iPhone or iPod touch won't charge

If your battery won't charge, charges slowly or an alert message appears, find out what to do.

Plug into a power source

To charge your device, follow these steps:

  1. Connect your device to the USB cable that comes with it.
  2. Plug into one of these three power sources:

Wall power socket

Plug your USB charging cable into a USB power adaptor, then plug the adaptor into the wall.

Computer

Plug your charging cable into a USB 2.0 or 3.0 port on a computer that's on and not in sleep mode. Don't use the USB ports on your keyboard.

Power accessory

Plug your cable into a powered USB hub, docking station or other Apple-certified accessory.

If you're trying to charge wirelessly with an iPhone 8 device or later, first make sure that you're able to charge with the USB cable that came with your device. If that works, then get help with wireless charging. For a third-party accessory, check that it's Apple certified.

When your device is charging, a lightning bolt will appear inside the battery icon in the status bar or a large battery icon will be displayed on your Lock Screen .

If your device charges slowly or won’t charge

Follow these steps and try again after each:

  1. Check your charging cable and USB adaptor for signs of damage, such as breakage or bent prongs. Don't use damaged accessories.

  2. Use a wall power socket and check for firm connections between your charging cable, USB wall adaptor and power socket or AC power cable, or try a different socket. 
  3. Remove any debris from the charging port on the bottom of your device, then firmly plug your charging cable into your device. If the charging port is damaged, your device probably needs a service.

  4. Let your device charge for half an hour.
  5. If your device is still unresponsive, force restart your device: 
    • iPhone 8 or later and iPhone SE (2nd generation): Press and quickly release the volume up button. Press and quickly release the volume down button. Press and hold the side button until the Apple logo appears.
    • iPhone 7, iPhone 7 Plus and iPod touch (7th generation): Press and hold both the side (or top) button and the volume down button until the Apple logo appears. 
    • iPhone 6s or earlier, iPhone SE (1st generation) and iPod touch (6th generation) or earlier: Press and hold both the side (or top) button and the Home button until the Apple logo appears.
  6. Let your device charge for another half an hour.
  7. If your device still won't turn on or charge, take your device, charging cable and charging adaptor to an Apple Store or Apple Authorised Service Provider for evaluation. You can also contact Apple Support.

If your device stopped charging at 80 per cent

Your iPhone may get slightly warmer while it charges. To extend the lifespan of your battery, if the battery gets too warm, software may limit charging above 80 per cent. Your iPhone will charge again when the temperature drops. Try moving your iPhone and charger to a cooler location.

iOS 13 and later use Optimised Battery Charging to slow the rate of battery ageing by reducing the time that your iPhone spends fully charged. Your iPhone uses on-device machine learning to understand your daily charging routine so that it can wait until you need to use your iPhone to finish charging past 80 per cent.* Optimised Battery Charging is active only when your iPhone predicts that it will be connected to a charger for a long period of time.

* Information regarding your charging routine is only stored on your iPhone. The information isn't included in backups and isn't shared with Apple.

If an alert says that your accessory isn't supported or certified

These alerts can appear for a few reasons:

  • Your iOS device may have a dirty or damaged charging port
  • Your charging accessory is defective, damaged or isn't Apple-certified
  • Your USB charger isn't designed to charge devices

Follow these steps:

  1. Remove any debris from the charging port on the bottom of your device.
  2. Restart your iPhone or iPod touch.
  3. Try a different USB cable or charger.
  4. Make sure that you have the latest version of iOS.
  5. Contact Apple Support to set up a service.
