What's the impact of distrobox (and by extension docker/podman) on battery life?

I'm trying out NixOS on my laptop right now and I'm loving it so far, but I was thinking of setting up distro box for ubuntu (mostly for a few developer environments dependent on it) and arch (for packages that aren't on nixpkgs yet). I was wondering about the battery life hit on a laptop and I couldn't find anything definitive on google/ddg. Has anyone here noticed a difference?
