> When macOS resumes from 0% battery, it's stuck in 30Hz mode

This sounds like detailed, testable data; I wonder how much effort it is to query this in code at resume just to confirm?

View on HN

iStat Menus will tell you the current "Frames Per Second", which is where I recall seeing it cap at 30Hz no matter what interaction I tried, after the 0% resume event. You have to basically scroll or do something that is supposed to be smooth to force the GPU to work as fast as it can, then immediately check the "Frames Per Second" in the iStat Menus toolbar. The "Frames Per Second" wouldn't display a number past 30Hz, whereas right now in the non-buggy state I can easily make it show 60Hz by scrolling in HN and clicking the iStat Menus toolbar immediately. It's been a while since I let my M1 Air fall to 0% but I am almost certain that's how I confirmed it.

I can't find "Frames per second" in iStat. I checked CPU/GPU section. Where is it?
