If the iPhone is not turning on, you might be able to fix it easily with a few simple troubleshooting steps. These troubleshooting tricks will apply universally to the iPad and iPod touch as well.

1. Check the Lightning Cable


The first thing you should check when your iPhone won't charge or turn on is the iPhone lightning cable. It is possible that the cable could be damaged. Try a different cable to see if that works. Make sure that you are using the original charging cable.

2. Check Charging Port

If the iPhone still doesn’t turn on, it may have a dead battery. Replace the iPhone 11 battery with a partially charged one and then try turning it on again.

4. Diagnose iPhone Display


Check to see of the iPhone display may be damaged in some way. This can cause you to think that the iPhone is not charging when it is.
