Long answer: depends on software/use, so the only measurable comparison between any machines is idle power consumption.
Min brightness: 5 Watts/16.5 hours
Half brightness: 5.3 Watts/15.6 hours
Full brightness: 7.7 Watts/10.7 hours
In my experience, basic lightweight desktop apps or web browsing, at half brightness, you will get 80% to 100% of a laptop's full brightness idle power draws, so in this case, a usable 8-10 hours. Doing something more intensive will depend on the Wattage you pull for those tasks - bogging down 2 CPU cores under turbo will consume another 20W of power, which will reduce the 80Wh battery to 3-4 hours of runtime. Playing a game with the GPU burning 60W and CPU at 20W, you'd have under an hour. Mine had 82.7Wh of new -battery capacity.
Anyway, those were the numbers I logged when I briefly owned this laptop. The CPU will maintain 4.7GHz all-core under stress testing, pulling 60W of power in Performance mode, 54W/4.6GHz in balanced mode, and 50W/4.4GHz in quiet mode. With 100W USB-PD as a power source, it will peak at 45W CPU TDP for 4.3-4.4GHz all-core load. The zen4 6-core 7640HS is as fast, and faster in some workloads, as the zen3 8-core CPUs.
It's a good machine, and zen4 is a nice improvement over zen3. There's nothing to dislike about this "value" 6-core chip - it's fast, and the GTX4060 is a sweet spot for 2023 laptops. Full dual-stick RAM upgradability too, and mine had zero backlight bleed, or any other panel issues.

So IF you have the choice most people are better with the non slim. But this is a heck of a price for a LOT of laptop.
Our community has rated this post as helpful. If you agree, why not thank Masejoer

Edit: I am currently using a Galaxy Book S, so I'm really not going to get anything out there at the sub 1200 price point for a carbon copy of what I'm using now.

I got the S mainly because it was super light and portable and was perfect for when I was in law school. Also big fan of the no fans/hyper cooling tech.
