My trusty Xbox One X has bricked during an update. I suspect a CMOS issue owing to it being unplugged from mains power almost always when not in use. I know that CMOS problems have killed some PlayStation units prior to Sony fixing the issue with an update. I’m wondering if I’m likely to encounter similar ramifications of treating a Series X in the same way vis-à-vis mains connection. Do they even have a battery? You’d think by now devices like this would use an EPROM but I can’t find a definitive answer other than opinions.
