Reported charge level suddenly drops to 0 for a sec, then back to normal

Tldr: I was sitting in a cafe when suddenly my system reported charge level to be critically low (0%) and initiated emergency hibernate. Whereas in reality the battery was charged to ~85% since half an hour ago I was at home and my notebook was connected to external power. The thing is, this low charge state was reported for, like, 200 ms, and then back to normal. Apparently OS still registers the event and does its thing. This happened a couple times, ~15 minutes apart. First time I cancelled…
