I was about to replace the battery on my iPhone X, when I stumbled upon my logic board panel which has 2 screws that seem to be stripped. Any idea on how to unscrew them?

try to put a rubber band in the center of the screw. Then try to unscrew it. The rubber band gives grip sometimes to the driver that is being used. Otherwise you might need to get a screw extractor. They have someone on i fixit.
