If your iPhone or iPod touch won't charge

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

Plug into power

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 outlet

Plug your USB charging cable into a USB power adapter, then plug the adapter 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 or later, first make sure that you can 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 charges, a lightning bolt appears inside the battery iconNo alt supplied for Image in the status bar, or a large battery iconNo alt supplied for Image on your Lock Screen.

If your device won’t charge

Follow these steps and try again after each:

  1. Restart your iPhone or iPod touch.

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

  5. Let your device charge for a half hour.

  6. If your device still won't power on or displays a battery icon on screen, force restart your device:

If your device stopped charging at 80 percent

iOS 13 and later use Optimized Battery Charging to slow the rate of battery aging 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 percent.* Optimized Battery Charging is active only when your iPhone predicts that it will be connected to a charger for a long period of time.

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

With iPhone 15 models and later, you might have a charge limit, which stops your iPhone from charging past a set limit. If you want your iPhone to charge past 80 percent, change your charging limit.

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

These alerts can appear for a few reasons:

  • Your iOS device might 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.
