I’ve heard a lot of people say your swap should be 2x RAM… but do I really need 32GB of swap?

I believe the swap partition is also used when hibernating. So when you use hibernate you need at least equal swap space as memory size.

Hibernate and suspend are different. I configure my laptop to suspend for 3 hours before hibernating. That means I can close the lid for lunch or a commute and instantly resume, but if I leave my laptop in my bag over a long weekend, the battery isn’t drained. Does it save much battery? Dunno. A few % over a few days maybe.

The point isn’t to save power, the point is that the laptop is completely off. You can even take out the battery if needed
