Hadn't bought a new laptop in a while. I wasn't expecting power efficiency to be that good! This is on a Lenovo Yoga Pro 7.

Do you have the option to switch to amd-pstate? Would be curious to see a comparison. What size battery do you have? How long does it last on a full charge for light usage (i.e. just browsing)?

amd-pstate gives me worse battery usage (when idle, hard to tell otherwise without a proper benchmark), which is strange because core frequencies were lower. tlp says the battery has 73Wh.
