Force Restart Your iPhone
When your iPhone won’t charge, performing a force restart eliminates any software issues that may prevent your iPhone from charging. The steps to force restart varies depending on which generation of iPhone you own.
iPhone 8, 8 Plus, X, XR or XS Max
- Quickly press and release the Volume Up button.
- Quickly press and release the Volume Down button.
- Press and hold down the Power button to the side until you see the Apple logo appear on the iPhone’s screen.
- Once you see the logo on the iPhone’s screen, release the power button.
iPhone 7 or 7 Plus
- Press and hold both the Power button and the Volume Down buttons until the Apple logo appears.
- Once the logo appears on your iPhone’s screen, release the buttons.
iPhone 6S, 6S Plus, SE, or Older Models
- Press and hold both the Power button and the Home button.
- Hold both buttons until the Apple logo appears on the screen.
- Once the logo appears, release the buttons.
When your iPhone restarts try charging it again.
Inspect the Charging Cable for Damage
If your iPhone won’t charge then there may be a problem with the lighting cable or adapter that charges your iPhone. Here are some things to look for to verify whether the cable or adapter is damaged:
- Connect your iPhone using your charger to your PC/or other USB power source and see if your iPhone charges. If your iPhone won’t charge, then it’s most likely the charger’s adapter that’s causing the problem.
- Charging your iPhone using a different lightning cable. If it charges then your iPhone charger needs to be replaced.
- Inspect the cable for breaks and inspect the adapter for loose connectors. If you find any, replace the charger.
Clean the Charging Port
When your iPhone won’t charge, there’s a possibility that debris are stuck in the charging port on the bottom of your device. The charger port may also be damaged.
- Use a soft dry toothbrush to remove debris from the charger port (brush gently).
Try charging the iPhone again. If the iPhone still does not charge then your charger port is damaged and you need to take it to an Apple Store for repair.
Check For Water Damage
Liquid damage or water damage may prevent your iPhone from charging or charging consistently. To prevent liquid damage avoid:
- Swimming or bathing with your iPhone.
- Exposing your iPhone to pressurized water or high-velocity water, such as when showering, water skiing, wakeboarding, surfing, jet-skiing, etc.
- Using your iPhone in a sauna or steam room.
- Intentionally submerging your iPhone in water.
- Operating your iPhone outside the suggested temperature ranges or in extremely humid conditions.
- Dropping your iPhone or subjecting it to other impacts.
- Disassembling your iPhone, including removing screws.
Perform a DFU Restore
A DFU restore resets your iPhone to the factory default settings. Use it as a last resort when your iPhone won’t charge or for other issues affecting your iPhone. The process, however, erases all the data on your iPhone.
- Connect your iPhone to your computer and start iTunes. (iPhone can be turned on/off)
- Press and hold the Power button and the Home button for 8 seconds.
- After the 8 seconds, release the Power button but continue to hold the Home button until iTunes shows the message “iTunes has detected an iPhone in recovery mode”.
- Release the Home button. Your iPhone’s screen should be completely black, which means that you’ve successfully entered DFU Mode.
- Follow the onscreen instruction restore your iPhone using iTunes.
