Past 5h, irrelevant to me. 5h is the longest continuous amount of time I can work on a hard problem, at least without the modern amenities that come with DC power, like a cold drink, etc.
After that, I get a break, and so does my laptop, for 30 min to 1h during which we both recharge our batteries.
That's far less sexy than a laptop with 24h+ of battery life, but I like to carry my laptop in a small bag, so the AC adapter doesn't intrude much.
Actually, I have 2 bags: both feature an AC adapter. I carry either the "big" bag with a regular Lenovo keyboard (I like it) and a 65W GaN adapter from Aohi (a cube about 2cm per side, that's not your grandpa power brick) or a flat 20W adapter (shaped like a 6mm thick credit card, with foldable blades) that's perfect for my Lenovo that barely sucks 10W (I measured).
With everything else equal, I'm offered a longer battery life with no tradeoff, I'll take it!
However, if I have to use arm binaries instead of amd64 binaries, I'm far less interested.
If I also have to use a laptop where I have little room to adjust the OS defaults, to the point of being in a walled garden, I start asking myself if I need it, and when.

I agree, but TBH with anything over 5h, I rarely need to look for one. Maybe it happens once every month?
Both the VM and the host runs Docker and containers. The host also runs k3s (Kubernetes single cluster) continuously for me to do various container running comparisons vs plain Docker.
With me logged in watching Netflix in a browser full screen it gets around 1.5 - 1.75 hours.
I guess if I were to just stream full screen without the VM running it'd run somewhat longer.
