I think it’s roughly 2 hours at 60fps, but I don’t know for sure because I have mainly been playing with power connected.

“Deep Rock Galactic: Survivor” has been a blast so far. I’m about 12 hours in.

I’m running DualSense on Arch without issues. It even uses the touch pad for mouse movements when not in-game (Steam).

Make sure to check the docs if you aren’t using Gnome: https://wiki.archlinux.org/title/Gamepad.

My only complaint is the atrocious battery life, but that’s not a Linux issue.

Check the second hand market. That’s how I got a 2TB one (with hub and Xbox Wireless controller) for less than what the 256GB one costs new and out of the sales period.
