If your iPhone or iPod touch won't charge

Find out what to do if your battery won't charge or charges slowly, or if you see an alert message.

Plug into a power source

If you're trying to charge wirelessly with an iPhone 8 or later, first make sure you can charge with the USB adaptor and 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.

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.


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.

Charging icon in iOS

As your device charges, you'll see a lightning bolt beside the battery icon in the status bar, or a large battery icon 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, like 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 service.
  4. Let your device charge for half an hour (if your device is unresponsive afterwards, learn what to do).
  5. 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 you see the Apple logo.
    • 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 you see the Apple logo. 
    • 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 you see the Apple logo.
  6. Let your device charge for another half an hour.
  7. If your device still won’t power on or charge, take your device, charging cable and charging adaptor to an Apple Retail Store or Apple Authorised Service Provider for evaluation. You can also contact Apple Support.

* If you aren't sure whether an accessory is damaged, take it to an Apple Retail Store or Apple Authorised Service Provider for evaluation, or 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 uses 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.* Charging in this way reduces the wear on your battery and improves its lifespan. 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 may be defective, damaged or non Apple-certified, or your USB charger may not be designed to charge devices.Follow these steps:

  1. Remove any debris from the charging port on the bottom of your device.
  2. Restart your device:
  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 service.
