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.
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.

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

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
