When the CMOS battery in your PlayStation 5 eventually dies, you will still be able to play it, according to a new report.
Based on a new video from Hikikomori Media, a PS5 with an expired or missing CMOS battery will not invalidate the launch of any PS4 and PS5 games on the console. The CMOS battery is used to power a PlayStation internal clock, and then when a game is started on it, the internal clock verifies the date and time on a remote server to ensure that you are able to play them.
In the past, when the CMOS battery either died or was removed, the PlayStation console would ask you to manually enter the date and time and then try to sync them online. However, if PlayStation Network did not work properly, your console will not connect to it, making all games unplayable. This applied to all digital games, as well as physical PS4 games and some PS5 games. But now, fortunately, it is no longer a problem.
Hypothetically, the problem meant that if PlayStation Network ever shut down permanently in the future, then you would not be able to play any game if the CMOS battery died. Sony released an update back in September that corrected this issue on the PS4.
This issue was brought to the forefront earlier this year when Sony announced it would close the digital PS3 and Vita stores, which it later changed. Several years from now, if you want to play on your PS4 or PS5, you will still be able to.
