In addition to replacing the U2 IC, I would recommend inspecting the board under a microscope to look for corrosion or deposits (as a result of water damage) that could be shorting out connections, this would lead to excess battery drain. If there is corrosion/deposits from water damage, the first thing I would recommend is a good cleaning.
