(Question) Anyone here with an Adder WS from System76? - eviltoast

I am rocking an Xiaomi Gaming Laptop (i7 9th, GeForce 2060, 32Gb Ram) with PopOS installed since day one. It is working fine (a bit annoyed because there is no way of finding a new battery for replacement), but I was thinking of switching to something more open source and with Linux officially supported.

Anyone here with an Adder WS (or any other System76 laptop)? How do you find yourself with it? Mainly curious about the battery life.

Thank you for reading.
