What is the typical power consumption of the steamdeck when in use? If you wanted to get an approximation as to how long a battery would last for. Also how much is efficiency likely to matter? If it was 30W and you had a 30Wh battery how likely is a 1 hour lifespan going to be? Would efficiency just be a rounding error or something like cut in half.
Is there a decent way of doing that in the GUI in windows? One of the more common commands I use at work which is the only time I use Windows. Rather than the PowerShell I usually use WSL for it currently because there are usually a few other things I will want to do after as well.
