Okay, I just remembered that I have an H2O and an old µSD card.

Confirmed. The bad news is, I can reproduce it on vanilla Nickel. It appears having an SD card inserted adversely affects the PMIC's ability to provide reliable information about the battery's state or something...

That bit of kernel code is quite frankly... an unreadable mess, so, who knows what's happening there.

On the other hand, the kernel on my H2O hasn't been updated since January 2017, so it's quite likely a *really* old bug.

EDIT: On the other hand, if I push the CPU to max clockspeed for a sustained period of time by essentially busy-looping, it works. o_O.

EDIT²: Not *completely* sure it's entirely SD-card related, because the gauge is generally still crap even without one, especially on < Mk. 6.
