I have a Ryzen 5 AI 340 powered machine and average about 6 hours. I might be able to stretch that to 7 if I dimmed the screen a bunch and only did light web browsing.
This is closer battery life to MacBook Neo, not an Air or Pro under the same workload.
My findings on it: https://sjg.io/writing/suspend-battery-drain-framework-13-ub...
IIRC my Thinkpad T14 G2 has S3 and it draws 0.3% per hour, pretty much in line with what Macbooks draw when sleeping.
