>The issue in most cases is that hardware that also runs windows will only support S5 Sleep so that Windows 11 can download fresh advertisements while your laptop is “sleeping”.
That explains some things. When I got my new laptop I played with Windows for awhile before installing linux, was surprised by how much the battery drained when unplugged and supposedly asleep. Was also surprised by how poor battery life in general was with Windows. Linux solved both issues, guess I got a laptop which properly supports deep sleep?
