You more than likely have a tristar U2 IC problem. You’ll need to find a repair shop that does micro soldering repair to replace it.

it's doesnt work' i replaced 2 tristar and the problem isn't gone, i have panic log that the iphone created
Ok, that wasn't in your original question, so that's why I suggested the tristar. I'm not familiar with board-level issues beyond the common problems.
