Not charging after replacing battery and charging port :_(

Hey folks, I replaced first the battery, then the charging port daughter board in my Samsung Galaxy A21s, but it still will not charge from any source. It boots and runs just fine on the ~50% factory charge in the new battery. It does detect the cable connection, and the software shows charging/fast charging status and even gives a time until fully charged estimate, but the total percentage only ticks downward.

I have also tried booting into recovery mode and leaving it plugged in for 30 minutes, per another post I found in my searching.

Really hoping a motherboard component isn't zapped, as I have plenty of experience with basic part swaps, but board work will be beyond my tools and skills.

Thanks for reading!

@stefanleinberg the only other thing you can try is the flex cable coming from the sub board to the main board. Those have a tendency of failing. Ultimately it does sound like you are having issues with the power management IC for your charging circuit. I know you mentioned that you are not yet into board repairs etc, but here is what you could check

To locate the components get the Samsung SM A217F Component Layout and use the search function of your PDF reader to locate the components (i.e. C6001 and so on)

I am in awe, you are an inspiration sir. If the cable doesn't fix it, I will see what I can learn of this skill.

Thank you!
