To charge your device, follow these steps:
Connect yourdevice to theUSB cable that came with it.
Plug into one of these three power sources:
Wall power socket
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 device or later, first make sure you're able to 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.

If your device charges slowly or won’t charge
Follow these steps and try again after each step:
Check your charging cable and USB adapter for signs of damage, such as breakage or bent prongs. Don't use damaged accessories.
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.
Remove any debris from the charging port on the bottom of your device, then plug your charging cable firmly into your device. If the charging port is damaged, your device probably needs a service.
Let your device charge for half an hour.
If your device is still unresponsive, 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 the Apple logo appears.
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 the Apple logo appears.
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 the Apple logo appears.
Let your device charge for another half an hour.
If your device still won't turn on or charge, take your device, charging cable and charging adapter to an Apple Store or Apple Authorised Service Provider for evaluation. You can also contact Apple Support.
If your device stopped charging at 80 per cent
iOS 13 and later use Optimised Battery Charging 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, 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.
With iPhone 15 models, you may have turned on 80% Limit, which stops your iPhone from charging past around 80 per cent. If you want your iPhone to charge past 80 per cent, you can either turn on Optimised Battery Charging or turn off charging optimisations.
