But now I think you can easily replace the battery without interrupting supply. Just solder two wires, connect additional battery and then replace the old one with a new one. Nothing extra necessary.
A CMOS battery lasts about 15 years.
The issue arises when the PS4 APIs are not available.
At what point does Sony drop their APIs?
Is it really just 'a few years'?
Now legally if I bought a game digitally could Sony refuse to offer it to me in 25 years because they can't bother to run some servers anymore? The PS3 announcement specifies that you can still download your games, only purchasing new stuff is no longer supported - which honestly feels weird , why not let people publish small indie games to PS3 too, is it hat extremely expensive to maintain those servers? Is it because of technical issues or is a people issue.
A common part I use is the Epson PCF8563, for example.

Now the PS4 doesn't seem to have an external chip from the teardowns I've seen. And the term "CMOS Battery" makes no sense other than shorthand for "battery that backs up CMOS memory".
But I'd wager the gates on the custom Sony silicon responsible for keeping time are CMOS or similar technology to minimize power when disconnected from mains (and how often is that? I'm curious what their design criteria is for that).

Nowadays BIOS is replaced by UEFI but we sometimes still call it "BIOS", so I thought that possibly "CMOS" battery is same story.
I know it's a meme but I always cringe a bit hearing that.
Yes, that's a pretty shallow promise not a guarantee. If they don't, there's always piracy to get access to the games you already legally purchased.
