My wife has an ~year-old Intel MBA. I have an M1 MBA.
Her battery's dead after 2 hours on Zoom or Discord or any of those battery-hungry web tech multimedia apps.
I've not tried taking it that far, but judging from where the battery on my M1 MBA gets to after a couple hours, I could probably do 6ish hours under that load (it's very dumb that some of these "productivity" programs are high-load and eat battery like crazy, but that's where we are).
If I avoid the webshit (Slack's unavoidable, for me, but I can ditch most of the rest, at least temporarily) I can work a whole day plus another half a workday on battery, no problem.
[EDIT] oh, and it feels faster than my hex-core AMD desktop with the badass graphics card and 64GB of memory does, under Win10 or Linux. Jank, jitter, and pauses galore, when doing basically nothing. Not so on the M1, unless I really abuse it. Granted that's largely the software's doing, but it doesn't really matter why it's better, in the end.
