Try quick troubleshooting steps
iPhone 8 and later models are compatible with wireless charging, and MagSafe charging in iPhone 12 and later models. Attaching a wireless charger turns on iPhone if it is off. You can attach a wireless charger to help confirm whether the iPhone turns on or not. This is helpful when the charging connector might be damaged.
Clean the iPhone. Check the iPhone charging connector for debris. Gently clean the connector using a small, non-metallic, soft-bristled brush. Ensure that the brush is clean and dry. Use just enough bristles to fit inside the connector. Twist the bristles to loosen and lift out debris. Brush debris away from the connector to avoid brushing debris into the connector.
Important: Unplug all cables and turn off the iPhone first. Don't use products containing bleach or hydrogen peroxide. Avoid getting moisture in any openings, and don't submerge the iPhone in any cleaning agents. Don't use compressed air.
Ensure that you’re using a recommended power adapter to charge the iPhone. Some power adapters may not provide enough power to charge the iPhone.
Use a compatible charging cable to connect the iPhone to a power adapter that’s plugged into an electrical outlet. Don’t use a computer port or wireless charging. Charge the iPhone for at least 10 minutes. Wait until an image appears on the screen or 10 minutes have elapsed.
Note: The iPhone may have entered a deep discharge state that requires 20 to 30 minutes of charging to turn on. The charging icon should be visible after two minutes of charging.
Gently move the cable around at the connection to ensure there is no intermittent connection. If the connection appears to be intermittent using a known good charging cable, the iPhone charging connector may be faulty or damaged.
Flip the charging cable orientation.
Unplug the cable and plug it back in.
Try a different charging cable.
Try a different USB-C power adapter.
Use a compatible wireless charging pad that’s plugged into an electrical outlet.
Disconnect the wired charging cable before you test wireless charging. When both are used simultaneously, charging defaults to the wired connection. Place the iPhone directly on top of the charging pad. Ensure that the iPhone display is faceup in the middle of the charger or in the location recommended by the wireless charging pad manufacturer.
Wait until an image appears on the screen or 10 minutes has elapsed. If the iPhone doesn’t turn on when using wired charging and turns on only when using wireless charging, then the iPhone may have wired charging issues.
