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?
