You can see current system current (while on battery):
Play around with some settings, but I'm on a 5.7 kernel, and it seems that on a modern kernel, the scheduler does a really good job of handling the cores to keep power use minimized. You could try turning off most of the cores to save a bit of power, but I'm not sure that gains you a lot.
But you've got USB-C charging. IMO, the far easier option is to just carry a USB-C battery bank (build a DIY one if you want and source the 18650s locally). I don't think even a lot of tweaking will change stuff as much as just carrying more battery.
Code:
cat /sys/class/power_supply/cw2015-battery/current_now
