bloatware
Even if you remove all that crap, battery life is nowhere near the same vs the M-series chips. So while it may be a problem, it’s still not anywhere close to the reason battery life sucks.
It can be if you run linux and throttle the chips. Even my older G14 last a long time, as the AMD SoCs are great, it can run fanless throttled down, and it just has a straight up bigger battery than razor thin Macs.
But again, it’s just not configured this way in most laptops, which sacrifice battery for everything else because, well, OEMs are idiots.
What specific driver and linux tools do you use to throttle your CPU?
Also throttling often produces the opposite result in terms of extended battery life as it likely takes more time in the higher states to do the same amount of work whereas running at a faster clock speed, the work is completed faster and the CPU returns to a lower less energy using state quicker and resides there more of the time.
I would be interested to hear your results. Have you done any tests comparing a throttled versus throttled system with the tools you are using?
On my G14, I just uses the ROG utility to disable turbo and make some kernel tweaks. I’ve used ryzenadj before, but its been awhile. And yes I measured battery drain in the terminal (but again its been awhile).

“Race to sleep” is true to some extent, but after a certain point the extra voltage one needs for higher clocks dramatically outweighs the benefit of the CPU sleeping longer. Modern CPUs turbo to ridiculously inefficient frequencies by default before they thermally throttle themselves.
Isn’t the screen eating most of the power in laptops? I just have an old T490 that I don’t use very much so I might be not that well informed.
I thought so too, but if Apple is getting more than 2x the battery life vs competitors while having a more dense screen, then I suppose it’s not as significant as I had thought.
Denser screen shouldn’t use more power though? Lighter, brighter, larger yes, denser IMO not so much.
