received a not charging iPhone 8, I have both the charging flex and the battery replaced. There is still no signs of charing.
And the battery indicator shows only 1% battery life, while it is actually 88%.
The wireless charging is not working either. however, it can be connected to iTunes.
Have no idea what to do next?

According to your description, The USB circuit works normally. The faulty may related to battery detection circuit. This circuit is consist of the battery connection J3200, Feld-effect tube Q3200, Q3201, Electric resistance R3202, R3201 and A11 processor U1000. So you troubleshooting start with these components.
