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.

If your device won’t charge

Follow these steps and try again after each step:

1. Plug your device into one of these power sources:

   • Computer

   • Power accessory

   • Wall power socket

2. Restart your iPhone or restart your iPod touch.

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

   

4. Use a wall power socket and check for firm connections between your charging cable, USB wall adapter and wall socket or AC power cable, or try a different socket.

5. Remove any debris from the charging port on the bottom of your device, then plug your charging cable firmly into your device.

   

6. Let your device charge for half an hour.

If your device stopped charging at 80 per cent

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

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

Find out what to do if your battery gets too warm

With iPhone 15 models and later, you may have a charge limit, which will stop your iPhone from charging past a set limit. If you want your iPhone to charge past 80 per cent, change your charging limit.

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

1. Connect your device directly to the charger, without any adapters or other equipment between your device and the charging accessory.

2. Remove any debris from the charging port on the bottom of your device.

3. Restart your iPhone or restart your iPod touch.

4. Try a different USB cable or charger.

5. Make sure that you have the latest version of iOS.
