I need some info here, this might be a silly question. So I did get a PS4 Slim on 4.01 and the package date was November 2016, so it is still in the box(opened only once to check fw), so my problem is that I will be unable to play my PS4 until May 2019 due to some personal reasons. Will keeping the PS4 unused, cause the CMOS battery or something to die?
