After a few seconds of charging the red light comes on?

[AC Question]

I have a Galaxy S6. I had it on the wireless charger last night. I got up this morning and had 0 charge. I plugged it into a usb charger and it will charge for a few seconds and a res light appears. Why? It's not charging, what happened?

A remote diagnosis is hardly possible. Take it to a repairer.
