My iPhone 12 says its charging but its not

I've had my iPhone 12 for a little over a year now. Woke up this morning to see it was at 60% even though it was plugged in all night. Every time I plug it in, it shows the little lightning bolt and says its charging but the percentage keeps going down. I've blown into the charging port, used a toothpick to try and gently remove debris/dust, and tried four different chargers/outlets and one wireless charger, same thing keeps happening. I heard that maybe this was my phone telling me I needed to update, but I couldn't install the update before it died.

Since it died I've had it plugged in and it shows that a charger is connected but hasn't changed from the Low Battery screen in 4 hours. I haven't had any previous issues with charging. Does anybody have any clue what the issue is or a way I might be able to fix it?

Any help would be greatly appreciated
