Sony’s recent PlayStation 4 firmware update v9.0 has quietly solved an issue with the console’s internal CMOS battery.
This battery powers an internal clock the console uses to check eligibility for game ownership. Without the battery – such as when it naturally drains – both physical and digital games are left unplayable without connecting online.
Reports this week suggested the problem had been fixed in the v9.0 software update, even though it is not mentioned in Sony’s official patch notes. Our Digital Foundry team has since been able to corroborate this and confirm the problem is indeed now solved.
