Help charging

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

Plug into power
If you're trying to charge wirelessly with an iPhone 8 or later, first make sure that you can charge with the USB adapter 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:

Connect your device to the USB cable that comes with it.
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.

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:

Check your charging cable and USB adapter for signs of damage, like breakage or bent prongs.1 Don't use damaged accessories.
Lightning to USB and a USB wall adapter
Use a wall power outlet and check for firm connections between your charging cable, USB wall adapter, and wall outlet or AC power cable, or try a different outlet.
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.

Let your device charge for a half hour (if your device is unresponsive afterward, learn what to do).
Force restart your device:
iPad models with Face ID: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Press and hold the Top button until the device restarts.
iPhone 8 or later: 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 for at least 10 seconds, until you see the Apple logo.
iPad with Home button, iPhone 6s or earlier, and iPod touch (6th generation) or earlier: Press and hold both the Side (or Top) button and the Home button for at least 10 seconds, until you see the Apple logo.
Let your device charge for another half hour.
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 your device stopped charging at 80 percent
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.

iOS 13 uses 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.2 Charging in this way reduces the wear on your battery and improves its lifespan. Optimized Battery Charging is active only when your iPhone predicts that it will be connected to a charger for a long period of time.

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. Follow these steps:

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