Learn how to charge your iOS device and get help when you have an issue.

Plug into power

Use the USB power adapter and USB cable that come with your device. For a third-party accessory, check that it's Apple certified. Then use these steps:

1. Connect your iPhone, iPad, or iPod touch to its Lightning to USB cable or Apple 30-pin to USB cable.
2. Plug into one of these three power sources:

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.

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.

Get help

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

If your device won’t charge or charges slowly

If you have very low battery and plug into power, a black screen or a black screen with a red battery might appear for a few minutes. Follow these steps and try again after each:

1. Check your charging cable and USB adapter for signs of damage, * like breakage or bent prongs. Don't use damaged accessories.
   
2. Use a wall power outlet and check for firm connections between your charging cable, USB wall adapter, and wall outlet, or try a different outlet.
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. Force restart your device:
   • On an iPhone 7 or iPhone 7 Plus: Press and hold both the Sleep/Wake and Volume Down buttons for at least ten seconds, until you see the Apple logo.
   • On an iPhone 6s and earlier, iPad, or iPod touch: Press and hold both the Sleep/Wake and Home buttons for at least ten seconds, until you see the Apple logo.
5. Let your device charge for another half hour.
6. If your device still won’t power on or charge, take your device, charging cable, and charging adapter to an Apple Retail Store or Apple Authorized Service Provider for evaluation. You can also contact Apple Support.

*If you aren't sure that an accessory is damaged, take it to an Apple Retail Store or Apple Authorized Service Provider for evaluation, or contact Apple Support.

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 non Apple-certified, or your USB charger isn't designed to charge devices.
