My iPhone 14 pro max is not charging

Plug it in to a charger for at least an hour , then try to power it on. If that doesn't work, make an appointment at a Genious Bar to have it looked at.

Clean out the charging port on your phone with a toothpick.

Try a different cable.

Try a different power supply.

Ok, post back if you need further help.

Glad to hear you got it working!

What is the problem she is having?

Good luck!
