Charging
My iPhone 13 pro max got low on battery so I plugged it in and noticed it hadn’t charged. I tried different cords, blocks and wall outlets even have it on a wireless charger and it won’t charge. Now it’s dead. What can be the problem?
See the suggestions in this link but if nothing works, schedule an appointment at your Apple Store Genius Bar for evaluation --> If your iPhone or iPod touch won't charge - Apple Support
