Try Charging Your iPhone With Multiple Charging Cables

When your iPhone or other Apple device won't charge or sync to iTunes, there may be an issue with the cable you're using. Lightning cables are prone to fraying and occasionally gunk or debris will get stuck in the USB end of the cable.

To see if your charging cable is not working, you can try using a friend's charger or inspect your cable for damage.

How Do I Try Charging My iPhone With Multiple Charging Cables?

  1. Try charging your iPhone or other Apple device using a different Lightning cable. If your iPhone charges with one cable, but not the other, then there's probably an issue with the first cable you tried to use.
  2. Inspect the charging cable that's not working. Use a flashlight and look inside the USB end of the cable for lint, gunk, and other debris.
  3. If you see anything inside the USB end of the cable, brush it out using an anti-static brush of brand new toothbrush.

DFU Restore Your iPhone

A DFU restore has the potential to fix software problems by completely erasing the code which may be causing your problem. The code is rewritten as if  your iPhone is brand new, so the software problem may get solved.

Think of it like a house that has cracks in the foundation. Rather than try and fix the cracks, we are building an entirely new foundation.

If you can, back up your iPhone before completing a DFU restore. Any time you do a restore, it erases everything from your iPhone. However, after the restore is completed, you restore all your backed up data back onto your iPhone.

How Do I DFU Restore My iPhone?

Watch our DFU restore video walkthrough on YouTube, or follow the steps below:

  1. Using a Lightning cable, plug your iPhone into a USB port on your computer.
  2. Open iTunes if you have a PC or Mac running Mojave 10.14 or earlier). Open Finder if you have a Mac running Catalina 10.15 or newer. It doesn’t matter if your iPhone is on or off.
  3. On an iPhone 6s or older, press and hold the Home button and the power button. On an iPhone 7, press and hold the power and volume down button.  
  4. After 8 seconds, release the Power Button, but continue to hold the power button (iPhone 6s or older) the volume down button (iPhone 7).
  5. Let go of the power button or volume down button when your iPhone appears in iTunes or Finder.
  6. Your iPhone’s display will be completely black if you’ve successfully entered DFU mode. If it’s not, try again from the beginning.
  7. Restore your iPhone using iTunes or Finder.
