That's a thing, yes. Turn your screen brightness down, or maybe only do a make -j2 and let the little cores idle. They don't have much L2 cache to share, so I'm not sure you gain a ton with them.
But if I start a kernel build with a fully charged battery and my screen at full brightness, I'm down to 50-60% battery by the time the build is done. I think it's just the nature of the power circuitry on this system - it can draw more than the charger can provide.
I mentally toss it in the "Yeah, beta hardware..." quirks category and figure that in a few revisions, USB-C Power Delivery will be used to solve the problem.
