iPhone 7 Battery Not Charging
My iPhone 7 is not charging when plugged in to both USB charger or with the wall power brick. It is a fully updated iPhone 7 purchased on launch day. The battery stays stuck at 16%, doesn't go up, doesn't go down. The software becomes super glitchy and won't move off of the home screen. The phone recognizes there's a charger plugged in and shows it to be charging but the battery icon or percentage never changes.
Any help from the community or Apple? Seems a bit ridiculous for a 4 week old phone?
Thanks!
