Battery life and heat on the FW16, notably windows without the graphics expansion bay

What I would do to measure minimum consumption is (on a fresh boot with no applications running) go to desktop, enter battery-saver mode, turn brightness to 0% (5% works too if you’re more comfortable with that, it’s not actually a huge difference in draw, but a big difference in viewability), open a battery monitoring software (e.g. powertop or btop) and then check on it in 5 minutes after it’s settled.

If I were in your shoes and found that power draw is still high after that, I’d be using htop to check if there are any processes using more than 1% of the CPU, and use nvtop to see if there are any applications using the dGPU (or better yet use cat to see if the dGPU is in d3cold with cat /sys/class/drm/card1/device/power_state).

Edit: There some more info in this thread: Minimum Power Draw Competition - Framework Laptop 16 - Framework Community

You can also try powertop --auto-tune
