S20 ultra won't charge past

I’ve tried a new charge port, ribbon connectors, wireless coil, and a new battery. Its says that the battery a 0% until I plug it in where it shows a charging symbol. From there I have to press volume down and power to turn it on. Then once its on, it won’t charge past 50%. I wish I knew what is all of the components is connected to charging so I could brainstorm on the issue.

Answer this question I have this problem too

Is this a good question?

If it used to be a demo or something check to see is retail is still on, if so try to disable it, then it should work fine, if it was not if it has most of it's storage taken up by ‘system’ then factory reset it, otherwise you might have to put in a new battery or try powering it off and charging it.
