iPhone does not charge

[MPB8250]

My IPhone 7 does not charge. I have tried everything. Changed the wire, the charger, the battery (everything Apple-produkt) and cleaned the hole were you put the wire. Also tried a reboot. When I changed the battery it worked fine until it ran out of power. Then it was dead again. Not even a charging-icon when I plug it in.
please help me

If you replaced the battery yourself, maybe you should double-check the connections.

Thank you Caroline. Tried it this morning. But the same

Perhaps the battery is faulty?

Maybe. But two faulty batteries at the same time?
