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.
Refer to steps and support resources in Troubleshooting Quick Checks.
Run manual and diagnostic tests
If the issue wasn’t resolved by following a support article or checking for potential causes, run these diagnostic and manual tests to help isolate the cause of the issue:
Follow all steps in If your iPhone won't turn on or is frozen to attempt to place the device in recovery mode. If an image appears in recovery mode, connect the device using a known good cable to a computer running the latest version of macOS. If the device is recognized by the computer, then the device has power. Restore the device if prompted.
Follow iPhone Repair Manual procedures to open the device and disconnect the battery. 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. Attempt to turn on the iPhone with the battery disconnected. If the Apple logo appears on the iPhone screen with the battery disconnected then battery replacement is recommended. If the iPhone remains off and unresponsive then the issue is likely unrelated to the battery.
Note: Battery and charge indicators may fluctuate briefly when you connect the iPhone to power or wake it from sleep. If this happens, wait a few seconds then check it again. The battery percentage may remain at 99 percent with a full charge, which doesn’t indicate a battery or hardware issue. Refer to iPhone Battery and Performance for more information.
Open and inspect the iPhone
If the issue wasn’t resolved or isolated by following support articles or running diagnostics tests, refer to the iPhone Repair Manual to open and inspect the iPhone. A damaged or out-of-place part may be causing one of the issues.

Run manual and diagnostic tests
If the issue wasn’t resolved by following a support article or checking for potential causes, run these diagnostic and manual tests to help isolate the cause of the issue:
Important: Devices with a non-genuine or unknown battery may exhibit several symptoms such as:
False failures with MagSafe or wireless charging
MagSafe is not detected
Unexpected shutdowns
Charging issues where the device does not charge above one percent
If any or all of these symptoms are present, check MRI results. If MRI results show an unknown battery flag with MagSafe failures such as MagSafe not being detected, or charging issues where the device does not charge above one percent, battery replacement is recommended. If battery replacement does not resolve these issues then continue troubleshooting. If the issue is unrelated to these symptoms then continue troubleshooting.
Use a MagSafe Charger or a Qi-certified wireless charging accessory 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.
