So my phone was dead and I decided to charge it 20 minutes go past and nothing happened I plug the charger in my other phone and the charger works I don’t know what I’m meant to do and this phone is an iPhone 7 I’ve put a light to see if anything was blocking it but nothing was seen

Plug the phone back to a power source and a force restart as outlined here Force restart iPhone - Apple Support
