Same machine here as well, running the latest Ubuntu (23.10) power profiles do work but auto-cpufreq is way more effective in increasing battery runtime for me.

I can get ~6h of runtime (~10W draw) if i mostly just code in VSCode + some browsing, with display at 1/3 brightness and the code being executed remote. Went with the OLED panel, so that definitively doesn't help battery runtime, but damn those colors are nice :)

I wish they would fit in a bigger battery or do some more tuning so that some cores could actually turn off if they aren't used, id happily accept the spool up time for big jobs, if this could increase the battery runtime a few hours/allow for higher brightness. What kind of runtimes/draws are you getting?

Also with an OLED, running at 20% brightness indoors, I'm able to get around a 7-8 watt power draw using the lowest AMD-pstate with a relatively modern Linux kernel.

This! One day laptop manufactures (excluding Apple) will understand that a vibrant colorful display is much desired by customers than a 1080p matt finish display.

The OLED that Lenovo is currently shipping for this and related hardware is not matte, but it's close. It's anti-glare, so it doesn't have the mirror finish of Apple panels.

When someone tells me "you know computers, is this a good laptop for me?", I usually reply along the lines of "make sure you like the picture on the screen and the keyboard/touchpad feels comfortable" - those are the things that can drive you furious or sad about the purchase sooner than anything else.

Can't you control which cores you use or what you put on them with the kernel cmdline? On x86-64 I use cpu0_hotplug nohz_full=1-3,5-7 rcu_nocbs=0-3,5-7 irqaffinity=4
