I have an older work laptop but a nearly brand new (comparatively) battery that's about a year, maybe 18 months old. If I'm actually using my laptop, it will last maybe an hour or two. I might get it to last 3-4 if I just have email up with the screen dimmed.
Not sure if it's Windows, too much work surveillance-ware, or just HP being garbage, but my M1 Mac will last twice as long as I've ever needed it to without getting plugged in. Even my older Intel MBP lasts most of the day.
