There is no current flow at the LogicBoard.
My iPhone was empty at 100% battery charge after 4 hours - also overnight. Then I rebooted the iPhone to make sure that no apps running in the background. Over night, the battery was empty again and could no longer be charged, and the iPhone could not be started anymore.
I suspect the problem could be on the battery and handed over the iPhone to an Apple partner for repair. I got the answer, "The problem is not on the battery. There is no current flow at the LogicBoard ''.
According to my Apple partner, the iPhone should be sent to Apple for exchange. However, I have made very interesting photos in the last few weeks (holydays) and I didn´t make any backup of these photos. Now I would like to change the LogicBoard myself to bring the iPhone back to work so that I can save the photos. Is the memory on the LogicBoard? Are there any other components between the battery and the LogicBoard whitch can infuence the current flow? Can you imagine that this defect can be corrected by replacing the LogicBoard?
(I posted this question also in german yesterday.)
Thanks for a quick reply.
Is this a good question?
